Effects of attentional demand, cue typicality, and priming on an event-based prospective memory task

The main purpose of this experiment was to examine the independent and interactive effects of three variables—attentional demand, cue typicality, and priming—on an event-based prospective memory task. High attentional demand was expected to lower performance, but cue typicality and priming were expected to improve performance. The prospective memory task entailed writing an ‘X’ after hearing items from four semantic categories (e.g. birds), while performing a free-association task. Results showed the predicted effects of attentional demand and typicality. Priming did not affect overall prospective memory performance but, as predicted, improved performance under conditions of high attentional demand with a typical cue. Overall, these results show the importance of cue and capacity variables, but they also support the value of examining how different variables in the prospective memory task can interact in affecting performance.
