Collaborative cognition, in which two or more people work together on a cognitive task, may be typical of everyday life, and may even represent an important aspect of everyday cognitive adaptation for older adults. We examined collaborative memory for stories by comparing younger (n = 64) and older (n = 66) individuals and dyads with collaborative performance produced by married spouses and stranger dyads. Overall, across four collaborative recall products (two positive and two negative performance indicators), some evidence for our hypothesis of general or selective collaborative effectiveness was observed. Moreover, such evidence was obtained at both an immediate and delayed recall episode. Discussion includes applications, limitations and suggestions for future research.
