Abstract:
OBJECTIVES: Creative production has been reported to decline with normal aging. With aging, there is a loss of brain connectivity and this loss may cause a degradation of convergent-associative processing. This study investigated differences in performance between young and older adults in the production of an original story using provided words. METHODS: The participants were 30 healthy younger and 30 older right-handed adults. Study testing included standardized language and cognitive assessments, as well as the experimental task, wherein participants were asked to create short stories incorporating three words that are not commonly related, semantically or associatively. Three judges, blinded to group, rated the resulting stories for originality, cohesion, organization, and appropriateness. RESULTS: The the younger adults’ stories were rated as being significantly more original and more appropriate. CONCLUSIONS: Integrating unrelated words into a cohesive and original narrative involves the activation of distributed semantic networks to develop novel associations. The older adults’ reduced performance on this task result from changes in neural network connectivity due to the white matter degradation commonly seen in normal aging as well as from decrements in frontal-executive network mediated lexical-semantic disengagement. Further studies using neuroimaging may help to elucidate possible neuroanatomic correlates of reduced associative creative verbal production in older adults.
