Our sense of humour may vary as you age

A person's age can influence how receptive they are to certain types of humour, a new study has found.

According to research by the University of Akron, young and middle-aged adults often find aggressive humour - jokes at someone else's expense - on TV sitcoms funny.

However, the study revealed that older people do not find these kinds of jokes amusing, instead preferring humour when characters have to overcome a difficult situation together.

Scientists behind the research believe the findings, published in Psychology and Aging, raise some "intriguing questions about our concept of what is funny".

For instance, they said some might interpret the findings to believe people's concept of what is funny is based on factors specific to their generation.

However, they suggested it could also mean people's sense of humour evolves over a period of time.

The research involved measuring participants' reactions to clips on TV sitcoms including The Office, Mr Bean and Curb Your Enthusiasm.

Dr Michael Apter, a Fellow of the British Psychological Society, comments:

"According to one theory of humour (Reversal Theory), the things that people find most funny are the very things that worry them the most. Humour is one of a number of mechanisms identified in the theory that convert the anxiety caused by threat into pleasurably high arousal. It is not surprising therefore that people in different age groups find different things funny, given that different aspects of life are likely to be troublesome for them.

"Thus young men and women trying to establish themselves and their careers frequently find themselves in highly competitive situations in which they have to act aggressively, or react to the aggression of others. Middle-aged and elderly people are more concerned with being parts of social and family networks, and feel threatened above all by the possibility of a loss of caring and love.

"This is what seems to be reflected in the contrasting kinds of humour enjoyed at these two age levels. Each converts its particular worries into its preferred form of humor. (Exactly how it does this is elucidated in Reversal Theory. See my forthcoming book 'Zigzag'.)"

Introducing the SuperAgers - the elderly people whose brains have stayed young

They say the slow inevitable decline sets in during our early twenties. Like a rocket reaching its apogee, once the brain is fully developed there is the briefest lull, and then it's all downhill, the last neural areas to develop being the first to start unravelling. By the time of old age, so certain are the impairments in mental processing that psychological tests are age-adjusted - "You're slow Bob, but not for your age. For an 80-year-old you're doing just fine."



But wait. A team led by Theresa Harrison at the Cognitive Neurology and Alzheimer's Disease Center at Northwestern University say they've identified a group of elderly individuals whose brains appear relatively immune to the physical effects of ageing.



Harrison and her colleagues identified these 12 "SuperAgers" (average age 84) by their exceptional mental performance. They outperformed 10 typical healthy older folk (average age 83) on a test that involved recalling lists of words, and they matched the performance of 14 healthy middle-aged volunteers (average age 58). The SuperAgers also matched the middle-aged on tests of naming things, attention and task switching, and identifying drawings by category.



Using a structural brain scanner, the researchers found that the SuperAgers had brains that seemed to have resisted the erosive influence of time. Whereas the typical older participants had thinner cortices and smaller average brain volumes (244mm cubed average) than the middle-aged (306mm cubed), the SuperAgers' brain surfaces were just as thick as the middle-aged and their brain volumes (288mm cubed) not significantly different in statistical terms. Moreover, there was one brain region - the left anterior cingulate - that was actually thicker in the SuperAgers than in the middle-aged.



"These findings are remarkable," the researchers said, "given the numerous reports that grey matter loss is a common, if not universal, part of normal ageing."



Across the groups, brain volume correlated with episodic memory performance. Although cingulate thickness did not, Harrison's team still think it's interesting that this region was thicker in the SuperAgers. Relevant here is previous research showing that early protein accumulations in the cingulate region have been detected in Alzheimer patients.



This new study provides a tantalising demonstration that continuing neural decline into old age is not inevitable. Crucial now is to find out why the SuperAgers are so well preserved. It's not known, for example, if they had larger brains and greater cognitive reserves to begin with, or if their brains have simply aged more slowly than usual. Perhaps their lifestyles will hold clues, although the obvious role of education appears not to be relevant with this group. Their time in education was no longer than the other participants and in fact only four of them went to university.



"Identifying the underlying factors that promote this trajectory of unusually successful cognitive aging may lead to novel insights for preventing age-related cognitive impairments or strategies for evading the more severe changes associated with Alzheimer’s disease," the researchers said.
