Electrical smiles spark better moods



The debate on whether facial expressions can influence mood rages on, with new work using electrical stimulation adding a fresh twist.

Can the physical act of smiling make you feel happier? According to the facial-feedback hypothesis, it can. However, the idea that feedback from facial muscles can influence our emotions has been hotly debated, with research in the field producing mixed results. In 2016, for example, one of the best-known findings in support of the idea — that holding a pen in the mouth, to simulate a smile, made humorous cartoons seem funnier — notoriously failed to replicate.

In 2022, however, research by a global team that included sceptics as well as supporters of the facial-feedback hypothesis led to the conclusion that while holding a pen between your teeth is unlikely to change your mood, there is some evidence that smiling can make you make feel happier. And now, into this mix, comes a new study in Emotion, which found that using electrodes to stimulate some of the muscles involved in forming a smile or a frown affected the participants' mood.

Themis Nikolas Efthimiou at the University of Essex and colleagues studied 58 people, who across a series of trials, had electrical current applied to either their zygomaticus major muscles, which pull up the edges of the mouth, into a smile — or to their depressor anguli oris muscles, which pull the ends of the mouth down, into an 'unhappy' expression.

In some of the trials, the participants were also shown images. These content of these images was either emotionally neutral, or was chosen to match the expression being induced by the electrodes. In other words, sad images were sometimes shown when the ends of the mouth were being pulled down, and happy images were sometimes shown when their mouth was being made to smile. These participants also regularly rated their mood, on a scale from 1 to 100.

When the team analysed the data, they found that the highest levels of positive emotions were reported when the participants' mouths were being pulled into a smile and they were looking at happy pictures. However, even in the absence of positive imagery, stimulation of these smile muscles was still associated with feeling more positive emotion. The researchers also found that the lowest mood ratings accompanied stimulation of the depressor anguli oris 'frown' muscles, especially when the participants were also looking at sad images.

One note of caution about these results is that the size of the effect of muscle stimulation on emotional experience were small. However, the induced muscle movements were themselves small, the team writes. And they did not target all the facial muscles that are recruited for a smile or a frown, only a few around the mouth. If the induced smiles and frowns had been more pronounced, perhaps the effects would have been stronger, they suggest. Further research will be needed to explore this.

Still, these results clearly do contribute to the ongoing debate about whether facial muscle movements themselves have any impact on our emotions. "The finding that changes in felt emotion can be induced through brief and controlled activation of specific facial muscles is in line with the facial feedback hypothesis," the team concludes.

Thumps, bumps and bangs: When your dog fears loud noises



An excerpt from 'Bark! The Science of Helping Your Anxious, Fearful, Or Reactive Dog', by Zazie Todd.

01 October 2024


Some years ago, when we still had both of our previous dogs, Ghost and Bodger, we went for a walk on a sunny afternoon. We ambled at dog pace, letting them sniff here and there and, in Ghost's case, listen for mice in the long, dry grass, cocking his head from side to side. We were partway up the hill on our way home when we heard a distant rumble of thunder. It was still bright sunshine, and the storm was way off on the other side of the valley. Even so, we decided to pick up the pace. Just two minutes later, big drops of rain began to fall, slowly at first, but quickly becoming heavy. The storm had jumped many kilometers all at once. We were hurrying now – not easy, as Ghost's health issues meant he was slow. I was already soaked to the skin when I felt the hairs on the back of my neck prickle and stand up. Just as we approached the top of the hill, there was a blinding flash of light and simultaneously one of the loudest noises I've ever heard.

Time seemed to slow right down. I was aware of light in the sky, approaching fast, and then a finger of blue stretched out to touch the transformer at the top of the hydro pole just meters away. In front of me, Bodger levitated several feet in the air and then landed on the road again. His coat was dripping, and he was pulling hard on the leash, desperate to get home. Behind me, my husband was doing what you're supposed to do when you sense that a storm is so close – get down to the ground. Ghost was standing still, staring at me. Even he looked startled.

"We have to get home," I said.

And then we set off, not at a full run, because Ghost couldn't manage it, but moving as fast as we could towards home. The road was running with water. I held on to Bodger's leash for dear life because I didn't want him to escape in the middle of a storm. Holding Bodger back, splashing through what was now a stream, encouraging Ghost to move faster, I was afraid of another bolt of lightning. The last two hundred meters felt like ten kilometers. Finally, we were home safe, scared, and sodden.

The next few times I left the house on foot, it felt like the sky could no longer be trusted and might smite me at any moment. Bodger seemed to feel the same, only worse. Over the next few days, he was reluctant to go outside in the dark. It took patience and many, many pieces of deli meats to get him to go out and pee at night. For weeks after, if it was even slightly cloudy, he was not interested in a walk. I can't say I blame him. Being almost hit by lightning was one of the most terrifying moments of my life.
Recognising a fear of loud noises

Fear of loud noises is the most common fear in pet dogs, affecting between a quarter and half of dogs, depending on the study. The sounds of thunder, fireworks, and gunshots are upsetting for many dogs, but any loud sound – even routine domestic noises like the vacuum cleaner – can upset some dogs. In one study, 25 percent of dog guardians said their dog was afraid of loud noises. But in follow-up interviews with a subset of the participants, it turned out that half of the dogs were afraid of loud noises. The most common responses to noises were trembling or shaking (43%), barking (38%), and seeking out people (35%). Perhaps surprisingly, some people who said their dogs trembled when there were fireworks, or sought out people in response to a sudden noise, nonetheless said their dog was not afraid of loud noises. This suggests that some people don't recognize the signs of their dog's fear, which is a problem because it means they don't do anything about it. In fact, less than a third of dog guardians had sought advice for their dog's fears. Unfortunately, fear of loud noises does not go away on its own.

A study of over 13,700 pet dogs in Finland puts the prevalence of sound sensitivities at 32 percent, and fear of fireworks in particular at 26 percent. The scientists suggest that genetics are one factor, and that breeders could help by not breeding from animals with known fears and anxieties. At the same time, they stress the importance of socialization. Positive early experiences can go a long way towards helping dogs cope with loud noises. This is also the finding of a study that has similar ballpark figures of 20.5 percent of dogs afraid of fireworks and 30.9 percent afraid of storms. Dogs who had been to a dog training class were less likely to be afraid of fireworks. However, it's not known if this is because people who take their dog to training class are more likely to be clued up on dog behavior, or if the classes included prevention exercises. Similarly, another study found that dogs who had been to puppy class were less likely to be afraid of noises; however, it also found that gradual exposure to sounds was one of the things least likely to be included in the puppy class curriculum.

Taken together, these studies show that if your dog is afraid of loud noises, you are definitely not alone. A number of approaches can help. The sooner these techniques are implemented, the easier it will be to make a difference, as every time the dog is subjected to the experience can make things worse. If your dog has spent many years cowering every time they hear fireworks, expect it to take some time to resolve the issue. When a fear of loud noises develops in an older dog, see your vet to rule out any medical issues.

One study looked for signs that might distinguish a dog simply being afraid of loud noises, from a dog being afraid of loud noises because they were in pain. Later onset of the fear was one sign, as dogs in pain were typically four years older than the fearful dogs without pain. Another sign was that the fear quickly generalized, so that, for example, the dog also became afraid of the situation in which the loud noises had occurred, no longer wanted to go out in the car, or became afraid of other dogs. The dogs in the study were examined for musculoskeletal issues such as hip dysplasia. When the dog was in pain, they were prescribed painkillers, and the dog's guardian was given advice on how to manage the dog to avoid making the pain worse. An individual behavior-modification plan was given for all dogs, and all improved—with the exception of one dog deemed to be in pain whose owner declined pain meds.

Another reason to see your vet about fear of loud noises is that in many cases psychoactive medication can help. Your vet may prescribe long-term medication. Or, if an event known to include fireworks is approaching – a national holiday like the Fourth of July, Halloween, or Bonfire Night (Guy Fawkes) – they may prescribe short-term medication to help your dog get through. I asked Dr. Rachel Szumel, a small-animal veterinarian in South Lake Tahoe, California, when to consider seeing your vet about medications if your dog is afraid of loud noises.

"Now. Yesterday. Right away," she said. "Because we know that noise phobias are notoriously difficult to treat with behavioral modification alone. So, if they're showing any signs of fear, you should be talking to your veterinarian about medications that help lower their sensitivity to noise so that you can start the behavioral modification part of things. If the dog is over threshold, no amount of chicken is going to make them love thunderstorms. But if they are on [a medication like] Xanax, that chicken actually does make those thunderstorms a little bit better. You can get a lot further with medications onboard."

Dr. Szumel also stressed that there can be times when pain is a contributing factor in fear, and that's another reason to see your veterinarian.
Training dogs not to fear noises

It was a hot and humid evening after another sunny day. Bodger and I set out for a short walk. But we only got halfway up the drive when we heard two loud bangs from a neighbor's property. It sounded like bear bangers set off to make a black bear go away. But it didn't matter what it was. Bodger immediately turned to run home, and I, as the one holding the leash, had no choice but to be dragged along by him. He was a big, strong dog, and so scared that nothing would stop him. I would have liked to offer him a treat, but it wasn't an option until we got back in the house. Then I gave him some of his favorite treats and put his leash back in the drawer, hoping to try the walk again in half an hour or so.

The approach I was using was counterconditioning: teaching Bodger to associate the loud bang with something great. I carried his favorite sausage treats in my bait bag and reserved them for when there was a bang. Research on what helps dogs with fear of loud noises shows how important it is to do something, rather than to wait and see, because doing nothing is associated with the problem getting worse. This research also shows that the approach I was taking with Bodger – known as ad hoc counterconditioning, because I was responding to sounds as they happened to occur, rather than arranging for them to happen – can be very successful. In fact, 70.8 percent of people who used it said that it helped. This is good to know, because, traditionally, approaches to fear of loud noises have focused on desensitization, a gradual exposure training. Desensitization works too, but it relies on a controlled environment. In real life, it's easy to suddenly find yourself in a situation where loud noises are unexpected and unpredictable. In those situations, if you don't do counterconditioning, you are undermining the desensitization process you had so carefully planned.

According to this research, relaxation training and preventive exercises also help dogs with sound sensitivity. Overall, this study showed that both puppies and adult dogs benefited from some kind of training. And given that dogs who were or were not being trained were equally likely to be on medication for their fear of noises, the research suggests that training, not just medication, does benefit dogs.

In fact, less than half of the people in the study (43%) had done any training to either prevent or resolve their dog's fear of loud noises. But amongst people whose dogs were afraid of fireworks, 70 percent had sought help, commonly from a trainer, veterinarian, the internet, or a book. And most people said their dog recovered from the fright within half an hour or an hour, or even right away, although some dogs took several days.

If you want to do desensitization, be sure to set it up very carefully. There are plenty of apps, CDs, and YouTube videos designed to help with this kind of training. Expect it to work better for things like fireworks and the sound of a car backfiring than for thunder, which is accompanied by atmospheric changes that you can't re-create. Listen to the sounds on a headset first (so your dog can't hear them), so you know what to expect. Set the volume super, super low. The aim is to have the volume so low that your dog barely even notices it – a volume much lower than you'd expect. As well, you should be prepared to do counterconditioning to those super quiet noises. This means setting up your treats well in advance. Once you start to play the sound, you can run to the fridge or the dog's cookie jar to get the treats. The open bar–closed bar technique is great here: once the noises start happening, so do the treats, but once the noises stop, treats stop too.

While it may be tempting to do this training at the same time each day say, 5 p.m., when you happen to be around and preparing dinner it works better if it happens at random times. You don't want to associate a specific time of day with the noises. You want to make it really clear that the (now very quiet) noises predict the treats, and nothing else predicts the treats. Over time, you can very gradually increase the volume of the recording.

But unfortunately, while training helps, many people make mistakes. I've been guilty of these training mistakes too. If you notice even the slightest sign of stress from your dog while attempting desensitization, stop the noises right away. And still offer food to the dog, because even if the desensitization part went wrong, you still want to get the counterconditioning part right. It's very common for people to play the sounds too loud and accidentally terrify their dog.

A common mistake with counterconditioning is to get the order of events wrong. If you know that sounds are going to happen and you reach for your treat before they occur, your training is not going to work the way you intend it to. This situation is called "backwards conditioning," and dog trainer Kate LaSala of Rescued by Training sees it often with her clients.

"Instead of teaching that fireworks predict chicken, we're getting chicken predicts fireworks, because you're doing it backwards," she says. Another time she sees this happen is when people are using a pressure wrap, such as the ThunderShirt, with their dog, to help calm them by applying gentle, constant pressure. "As humans, we have the benefit of knowing it's the Fourth of July or it's New Year's Eve. I know at 10 o'clock people are going to start shooting off fireworks. So we anticipate that this is going to happen and we prepare and say, 'Oh, I'd better put the ThunderShirt on the dog because I know they're about to shoot off fireworks.' That can actually backfire, because then the ThunderShirt becomes a tip-off to the dog that fireworks are about to happen, and the shirt itself can become panic-inducing for the dog."

Like Dr. Szumel, LaSala stresses the importance of seeing a vet in case your dog is in pain, or in case medication is recommended. One of the times when clients especially struggle, she says, is when the dog is too anxious to take food. "If you have a dog who's really over threshold and they just are so anxious and over threshold that they won't even consider taking food, it's really difficult to make progress in training, because they've got bigger fish to fry. They're just so panicked. The world is exploding around them, and the last thing they want to think about is your chicken and cheese. So getting that anxiety down to a manageable level where they don't think the world is ending around them is not just the most humane thing to do, it's the best thing to do for training."

One thing is certain: as with so many other fears and anxieties, seeking help from a professional is a sensible idea.
Coping in the short term

In some summers, many bears ambled through the neighborhood where we live, and therefore many bear bangers were set off to frighten them away. This wasn't good for Bodger's nerves, but it did provide lots of training opportunities. It became a recurring theme on sultry summer nights. Bodger and I would set out on a walk. Sometimes we would get halfway down the street, sometimes we would not even leave the driveway. Then we'd hear a loud bang. Bodger would turn to run and I'd follow, offering treats that he would not eat till we got safely indoors. But there was progress, of sorts; he was not running quite so fast, and I no longer felt like he was going to pull me over. It was encouraging, and showed the training was working even though it was only ad-hoc, whenever loud noises occurred.

After a while, something interesting happened. He would hear the bang, I would grab some treats from my bait bag, and he would eat them hurriedly. Then we'd run home.

Training takes time, maybe months or longer. What I was doing in those moments was training, along with giving Bodger a choice the choice to run home, where he felt safer. So what can you do if there isn't time, and you know that a bout of fireworks is just hours or days away—say, that the Fourth of July or Bonfire Night is coming up fast, or that there's a thunderstorm in the weather forecast? One thing is to make sure you know that your dog can't escape. It's not unusual for dogs left in the yard to be so terrified of thunder or fireworks that they find a way out and run away in a complete panic (even though they've never escaped before). So keep them safe by keeping them indoors. And, as always, make sure your dog has both a microchip (that can't be removed) and a collar tag, so that if they do get loose and are found, the finder can identify your dog and call you directly. Also plan ahead by taking your dog out to toilet well ahead of the start of any loud noises.

Make sure your dog has somewhere safe to hide during the noisy event. In a thunderstorm, that's not in the bathroom next to a pipe, even though that may be where they would like to pick because it's the smallest space. Remember that lightning can transmit through the ground, and that if it strikes the house, the electrical current can travel along the plumbing. It's the same reason that you shouldn't take a shower during a thunderstorm. The hiding place should be in a room with the drapes closed to block out the light from fireworks or lightning, or in a basement, which will block some of the noise too. If your dog happens to be cratetrained, their crate might make a good safe space, and you can use blankets to block out the light.

Masking the sound is another good idea, but it can be hard to do a good job of this. Simply turning the TV on does not work so well, according to dog writer Eileen Anderson, who also happens to have a background in acoustics.7 She recommends using something with a low frequency for acoustic masking, because those low frequencies will help drown out the low rumbles. She says the best options are to use a fan or to play random noise (especially something called brown noise) through your speakers; running the dishwasher or washing machine, or putting a pair of sneakers in the dryer, are other good options. The masking noise needs to have some low frequencies to do the best job. At other times – for example, when you want to mask the sound of workers in your house – you can use an audiobook. But it's important to know that the masking sound isn't something your dog is afraid of, so pick something they know and like. In other words, only play loud rock music if you know already that your dog is okay with it!

And remember that it's fine to comfort your dog if that's what they'd like. Some dogs will be too terrified to take food or to want comfort, but if they will take treats, that's great, and if they seem to want to be petted, then you should pet them.



On some of the last summer evenings before Bodger was taken ill, we made real progress with his fear of loud noises. When we heard a bear banger, he'd turn as if to head home, then stop and look at me expectantly. "I'll have my treats, please," he was saying. And so I gave him some of his favorite sausage treats. Then we didn't even have to run home. We could walk, slowly. Sometimes he would even change his mind and we could turn and head back out again. He trusted me that he had the choice to go home, and he was no longer so terrified of the loud bangs. We'd gone from what felt like a near-death experience with thunder to seeing bear bangers as a signal for a snack. Counterconditioning may take time, but it works.



"For us, with dogs, it's often love at first sight. But not all dogs immediately love us back. Fearful dogs need patience, time, and empathy as they encounter new things and people in the world.

I wish that people would prioritize relationship-building over training. This means ensuring your dog feels safe. Put this need over your needs to cuddle, walk, or show the dog off to your friends. Help the dog create positive associations with you. These associations are more important than learning to sit or fetch. Show the dog that your presence predicts something wonderful: lots of treats, a game or toy, anything you are sure the dog loves. Be lavish with treats and toys and fun. Be patient as the dog learns to associate you with good stuff, and eventually is happy to see you coming. Use this time to reflect on your dog's needs and commit to meeting those needs. A great relationship with you is your dog's gateway to the rest of the world."

Feeling Better About Our Bodies





Content note. We discuss how we might feel better about our bodies. So we touch on the social messages we get about bodies and this includes us talking about fatphobia, diets, ‘health’, disablism, but we don’t go into much detail. It’s a long one — sorry about that.



Around the time of year that we recorded this podcast – early Spring – it’s easy to feel bad about our bodies. Cultural scripts suggest that we should overindulge and hibernate over the Winter, but that after new year we should be follow resolutions to diet and ‘get in shape’ for the summer ‘beach body’.



The media doesn’t help. At the moment there are a number of billboard adverts and makeover TV shows focusing on weight-loss and ‘improving appearance’. Particularly problematic are the links that are made between looking a certain way and ‘health’ and ‘fun’. Not only are we meant to have a certain appearance in order to be attractive and sexy, but also we’re blamed and shamed for being ‘unhealthy’ if we don’t conform to cultural beauty ideals, as well as often internalising the idea that caring about ‘looks’ is a fun and pleasurable thing to do, and to do otherwise would mean being a killjoy.

But the beauty ideal is incredibly limited. Looking around at the aspirational bodies that surround us they’re overwhelmingly young, thin, white, ‘flawless’, non-disabled, and gendered to match the ideals of rugged masculinity and delicate femininity, and a good deal of wealth is required to buy all the products necessary for maintaining such an ideal. We scientifically estimate on the podcast that 97% of people will not match these ideals for one reason or another, and all of us will move away from them as we age of course.
Love your body?

Most of us are likely to feel bad about our bodies if we’re surrounded by such narrow body ideals that we can’t possibly match up to. But what can we do about this? There has been a move among some people to replace the ‘change your body’ message of so much advertising and other media with a ‘love your body’ message.

This is pretty risky because it still locates the problem in us as individuals – rather than wider society. It’s bloody hard to love your body when the whole world is implicitly – or explicitly – telling you not to. If we receive the message that we should be able to easily love our bodies, that gives us yet another thing to feel bad about.

There’s a real tension when we live in a very individualising culture to know how to address things like this without continuing to individualise our struggles. At megjohnandjustin.com, we find the following diagram helpful – for all kinds of things – to think through how they work on multiple levels, and how we might address them on all those levels too. We can’t just try to relate differently to our body on an individual level if the people around us, our communities, and wider culture simply stay the same.

In the podcast we explore what we might do at each of these levels:Society – We could notice the images around us and be critical of them. We could confront fat-shaming remembering that it’s actually poverty, type of diet, and fitness that relate to health – not fatness; that being ‘underweight’ is generally more risky health-wise than being ‘overweight’; that these categories are based on an old model of measurement that doesn’t relate to how bodies are these days; and that shaming people about their bodies makes everything far worse – not better – for them. We could engage in body-related activism. We could seek out different subcultures that incorporate more diversity of bodies or expand our ideas of what is beautiful.
Communities – We could deliberately share materials that are critical of body ideals, or which incorporate a wider range of bodies. We could curate our social media accounts to avoid body-shaming from others, and to put out different messages ourselves, including filters and content notes. We could find communities which are trying to cultivate different ways of engaging with bodies. We could deliberately follow communities online which challenge narrow body ideals, including fat activists, disability activists, dwarf community activists, age activists, etc.
Interpersonal Relationships – We could keep an eye on whether we shame people in our lives for aspects of their bodies or bodily practices and try to stop doing that. We could have consent conversations about how we like to be treated in relation to our bodies, and what we find difficult from others.
Yourself – We could try to incorporate more embodied experiences into our lives where we feel ‘at one’ with our bodies rather than separate to them and scrutinising of them. These can include activities where the body is in motion, being alone, being in nature, etc.


Acceptance and Change

The ‘love your body’ message risks replacing the idea that we should always change our bodies to fit beauty ideals with the idea that we should always accept our bodies as they are and that changing them in any way is a bad thing that’s always about conforming to cultural norms.

Actually each person needs to find their own way of navigating the possibilities of change and acceptance in relation to their bodies (and in other areas). For example bodily changes of various kinds can be extremely helpful in decreasing physical pain and discomfort and/or improving mental health and/or opening up new possibilities in our lives.

Many trans people, disabled people, people with chronic health conditions, fat people, and others face a constant barrage of messages from one group of people telling them they should make changes to their bodies, while another group of people tell them they shouldn’t and that they should accept their bodies as they are. It’s not for anybody else to tell us how we should relate to our bodies, and – as a culture – we should help everyone to navigate these complex decisions about change/acceptance and support them through the various options instead of telling people what they should or should not do with their bodies.

Want to play better? Try changing your avatar's gender

New study finds that from NPC kills to exploration, gamers' avatar gender affects various in-game behaviours.

07 October 2024

By Emily Reynolds


If you've played any recent videogames, chances are at some point you'll have spent an inordinate amount of time customising your character. Tweaking clothing, facial features, and body builds can add new layers of enjoyment to the gaming experience, and help us connect to the characters that we (at least in some series) play a large role in creating.

As well as changing how your avatar looks, many games now also give the option of selecting your character's gender. As Kim Szolin and colleagues from Nottingham Trent University explore in a new paper published in Entertainment Computing, this particular customisation choice can actually change how we behave in-game – both for better, and for worse.

This study involved 353 adult participants, most recruited from video game forums. Everyone who took part had played one particular well-loved title: Fallout: New Vegas, an open-world roleplaying game in which players act as a courier trying to survive in an apocalyptic landscape. Most participants (276) identified as male, and the rest as female (77).

Participants answered questions based on a save file from a previous game of Fallout to understand how they played and with what avatar. Firstly, they shared their own gender identity and the gender of their avatar, as well as how long they had spent playing. Next, they indicated how many quests they had completed; how many locations they had discovered; and how many non-player characters (NPCs) and enemies they had killed.

Analyses uncovered several interesting relationships between the players' gender, avatar gender, and in-game behaviour. In terms of quest completion, male players with a male avatar completed an average of 76 quests, compared to 66 quests when playing with a female avatar. For women, however, avatar gender had no impact on how many quests they completed.

When looking at the number of in-game locations discovered by players, female players with a female avatar found 30% more locations than those with a male avatar. In this instance, though, there was no significant difference in location discovery rates for male players playing as either gender.

There was no significant interaction between player gender and avatar gender on the number of NPCs and enemies killed – though perhaps counter to expectations, those with female avatars had a higher number of NPC kills than those with male avatars, regardless of their own gender. Men were more likely to kill NPCs than women.

Congruence between the gender of a player's avatar and their own identity seemed to improve game performance in several areas, chiming with other research suggesting that a visual similarity to an avatar can improve gameplay. The team suggests that increased identification with a character may be the driver behind this, engaging the player more deeply and improving their gameplay.

As for why female avatars had a higher NPC kill rate, the team argues that this may be to do with the game's "absence of physical world virtual users to reinforce societal expectations of gender and aggression." So, while in the real world women may be seen as less aggressive than men, a world in which gender roles are more regularly less fixed and binary may give players the freedom to engage in less stereotypical aggressive behaviour.

What wasn't covered in the study was gender identity in a broader sense. The team didn't explore whether participants were cisgender, transgender, or otherwise gender diverse — factors which may influence the exact ways players experience, relate to, or embody their avatars. The reasoning behind choosing different gendered avatars was also not probed, but future explorations of this could open up further interesting insights.

Learning from women and girls




Key insights from the five year Women and Girls Initiative
Research & evaluationPublic SectorCommunityGender & diversity






Still from the Women and Girls Initiative animation



Back in 2016, The National Lottery Community Fund (the Fund) invested over £44 million in the women and girls’ sector through its Women and Girls Initiative (WGI). We are proud to have been a key part of this work, delivering WGI Learning and Impact Services with our partners, DMSS Research and CWASU, since January 2018. As we now publish the Final Impact Report, it seems fitting to share a few reflections, and signpost to some of the WGI legacies.

It has been so refreshing and such a joy to work on the Women and Girls’ Initiative (WGI). It demonstrated what could be achieved when women and girls are listened to and given the time and space to access support as, when and for as long as it is needed. It was a brave and insightful investment from the Fund, with flexibility embedded. The WGI enabled projects to develop their expertise, improve the availability of holistic, specialist support and build stronger evidence of what works well. It supported projects to develop, adapt and grow, whilst ensuring the voice and influence of women and girls remained at the centre of this support.

As Learning and Impact Services partners between 2018 and 2022, we were also able to be flexible and adaptive to projects’ needs, particularly during the COVID-19 pandemic. Activities included running Theory of Change and evaluation workshops, facilitating action learning groups, masterclasses and webinars — and bringing together a range of public outputs: blogs, briefings, reports, and audio-visual resources.

In 2020, when an in-person conference became impossible because of pandemic lockdowns, we adapted our support offer by hosting regular on-line community calls for project staff. As an alternative to the conference, we commissioned Leeds Animation Workshop to create an animation, involving project staff, volunteers and participants in the process. All published outputs produced through the Learning and Impact Services can be found through the Women and Girls Initiative home page and via references throughout the Final Impact Report.

‘I understand the power of words to both uplift and hold back’



Dr Denise Miller on her journey to being awarded a National Teaching Fellowship by Advance HE.

07 October 2024


During my secondary school years, one moment stands out with particular clarity. I shared my aspiration to become a teacher with the deputy headteacher/careers advisor. His response, a dismissive laugh, suggested that my goal was unrealistic and unworthy of serious consideration. Rather than allowing this to deter me, it fuelled my determination to prove that I was more than capable of achieving what he had deemed improbable.

You see, I come from a long line of activists, dreamers, and achievers. My amazing parents, Eric and Shirley Miller, migrated from Jamaica to the UK in search of a better life in the 1950s, during the Windrush era. They embodied resilience and perseverance, traits that were deeply ingrained in me as I grew up in this supportive environment. Their influence instilled in me a quiet confidence that I could succeed in any endeavour I committed myself to; albeit they told me that as a Black woman I would have to work at least 10 times harder than my White peers. This belief sustained me until 1996 when I qualified as a primary school teacher, absolutely cognizant of the power of words to both uplift and hold back.

My journey in education did not end there. In 2004–2005, I undertook training to become an educational psychologist. Once qualified, this role became a natural extension of my commitment to equity, diversity, and inclusion (EDI). Almost a decade later, I returned to the University of Greenwich, where I had initially trained as a teacher, to contribute to institutional change. In my academic positions, I remained fervent in my mission to advance EDI by working across various roles to develop educational environments where all university students felt valued, respected, and supported.

Like many others, however, my career in higher education has had its challenges. Notably, in 2022, I was made redundant from the School of Education. While this was a significant setback, I viewed it as an opportunity to refocus. I transitioned into a new job within the School of Human Sciences, and thereafter, I continued my work towards achieving educational transformation on local, national, and international platforms.

The impact of my efforts and hard work is reflected in the recognitions I have received for my contributions to teaching, learning, and research. A career highlight came in 2024 when I was awarded the prestigious National Teaching Fellowship (NTF). This achievement was historic, as I became the first Black person at the University of Greenwich, and the first Black educational psychologist in the UK, to receive this honour. For me, the NTF represents a personal milestone and also a symbolic victory for people from underrepresented and marginalised backgrounds who are invariably 'working harder' in academia.

So, for those of you who are aspiring to apply for the NTF, my advice is this. Begin the process as early as possible, as preparing a winning application requires considerable thought and planning. Indeed, I found it challenging to balance working on my application with my professional commitments and personal responsibilities, but an early start allowed me to create a structured timeline with space for multiple revisions.

It is equally important not to compare yourself to others. During my application process, I frequently questioned whether my achievements were 'good enough' compared to other candidates. However, you should keep in mind that the NTF recognises excellence in many forms, so just focus on your own unique strengths and contributions.

A significant part of the application process concerns self-reflection and identifying areas for improvement. However, balancing the need to acknowledge shortcomings while highlighting accomplishments can be quite tricky. I would recommend surrounding yourself with mentors and colleagues familiar with the NTF process. Seek constructive feedback from people who can critically evaluate your drafts and who can help you to address the criteria efficiently and effectively.

Finally, make the most of your word count and avoid unnecessary 'waffle'! Instead provide specific examples of your work that clearly align with each criterion. Develop a cohesive and compelling narrative that emphasises your influence and impact, and importantly, support every single claim with strong qualitative and quantitative evidence, such as student feedback and outcomes, evaluative data.

I hope my journey to NTF serves as a source of inspiration for those of you who have encountered doubt, ceilings, or marginalisation, and it encourages you to pursue your aspirations with confidence.

Could exposure therapy, without conscious exposure, actually work?


New meta-analysis suggests that unconscious exposure therapy is surprisingly effective.

23 September 2024

By Emma Young


Phobias are among the most common psychological disorders, and are the most common anxiety disorder. An estimated 6% of the population suffer from full-blown arachnophobia, for example, while around 1 in 10 people in the UK are affected by claustrophobia at some point in their lives.

The standard treatment for phobias is 'exposure therapy'. For someone with a phobia of spiders, that could mean encouraging them to look at pictures of spiders, encounter virtual reality spiders, and ultimately even hold a spider — all in a safe setting. The aim is to help them to confront and overcome their fears, lessening their severity along the way.

There is abundant evidence that exposure therapy does work. But it is distressing, and this means that most people with phobias are reluctant to start therapy, or, if they do, they often drop out. A new paper in the Psychological Bulletin concludes, however, that unconscious exposure therapy — in which the person isn't even aware that they are being exposed to the object of their phobia, and so which does not stress them out — can be remarkably effective.

Paul Siegel at the State University of New York and Bradley S. Peterson at the University of Southern California conducted an exhaustive meta-analysis of findings from 39 studies that used an unconscious exposure intervention.

The interventions were not identical. In fact, the researchers identified 10 different approaches. In the 'very brief exposure' paradigm, for example, sufferers receive a series of 'microexposures' to images of their feared object (such as a spider), with each image immediately followed with another, benign image, to help to prevent it from being consciously recognised.

Another intervention, called 'spiderless arachnophobia therapy' takes a different approach. It involves showing people images of objects that resemble spiders, but which they don't consciously appreciate are spider-like — such as a camera tripod with its legs bent to resemble spiders' legs. Though the images themselves are consciously seen, this intervention relies on unconscious processing.

Overall, 38 or the 39 studies found that the intervention made a difference. Based on their analysis, Siegel and Peterson conclude that there is "ample evidence" that unconscious approaches work to reduce fear responses — even in highly phobic participants — and that they do this without inducing feelings of fear. Though the effect sizes on behaviour (willingness to approach a live spider, for example) were not quite as large as those found for standard exposure therapy for specific phobias, they were still "mostly large", the pair reports.

It's also worth noting that the vast majority of these unconscious exposure studies consisted of only a single 'treatment' session, whereas standard exposure therapy is often conducted over multiple sessions. Perhaps, then, a series of unconscious treatments may be even more effective, but further work is needed to explore this.

Based in part on brain scan data from some of these studies, the researchers think that the reason unconscious therapy can work is that our brains react both unconsciously and, separately, via different pathways, also consciously to scary things. They think that when someone with a spider phobia is repeatedly unconsciously exposed to a picture of a spider, their amygdala, which detects threats, is activated, but they don't go on to experience a racing heart or sweaty palms — or feel fear. With repeated 'training', this "likely revises the memory representation of phobic stimulus", the pair writes — so that their brain learns that this object should not trigger fear. "In essence, we are arguing that unconscious experience reduces fear by preventing fear itself," the researchers write.

Exactly which brain regions play a role in unconscious exposure therapy is not yet well understood. Neither is it clear yet which types of unconscious phobia intervention may be the most effective. But, given that specific phobias are so common, and that research shows that they often precede the development of other types of anxiety disorders, the pair argues that further research into unconscious approaches is now needed. They add that in theory, it's possible that the approach may also help people with some other anxiety disorders, such as PTSD.

"Psychologists have long maintained that feared objects and situations must be directly confronted to reduce fear of them," Siegel and Peterson write. "The findings of this review call this long-standing belief into question and suggest that a new generation of exposure therapies that reduce fear via unconscious processing is on the horizon."

However, since the unconscious and conscious memory systems that underlie fear-related learning are not completely independent, they think that the ultimate phobia treatment will probably target both systems. First, an unconscious treatment might make someone with a spider phobia, say, less terrified of spiders. This could then make it less stressful for them to embark on standard exposure therapy, in which the conscious, cognitive processes of phobic beliefs and subjective fear are tackled.
