The goal of conducted research was to analyse the functioning of prospective memory in daily life, depending on structure of everyday life and type of prospective memory task. Fifty people took part in Study 1, including students and working people with higher education. The respondents generated intentions for the next week, classed them as three types of intentions (event-based, time-based and activity-based), and then assessed performance of these intentions after a week. As expected, students planned more time-based prospective memory tasks than event-based and activity-based tasks. However, unexpectedly and contrary to the results of previous laboratory research, they performed better on time-based tasks compared to event-based tasks. In order to replicate the second unexpected finding, Study 2 was conducted in which 43 students took part. Similarly to Study 1, students handled time-based intentions better than event-based intentions. The results suggest that differences in the level of difficulty of three basic types ofprospective memory tasks that have been found in laboratory research, do not generalize to the realization of respondents’ individual intentions in everyday daily.
