| Annotation | It was hypothesised that increasing the number of relevant pieces of information would reduce the difficulty associated with processing irrelevant information on a categorisation task, since the number of relevant solutions to solve the problem would increase, while the total number of pieces of information to be processed would remain the same. This hypothesis was tested on 26 young adults (undergraduates at the University of Tours) and 30 older people (volunteers canvassed from Université du Troisième Age) using a task requiring the matching of a stimulus figure to one of the two response figures having one or more attributes in common with the stimulus. In line with previous findings, the results indicated an age-related inhibitory decline. However, consistent with the hypothesis, as the number of relevant attributes increased, the performance of older people improved and response time decreased, supporting the notion of latent cognitive resources.
