Affective state and event-based prospective memory.

Event-based prospective memory tasks require the realisation of a delayed intention at the occurrence of a specific target event. The present research investigates how performance in this kind of prospective memory task is influenced by the current affective state. By manipulating participants' mood during intention realisation we tested two competing models of mood effects on memory (i.e., a capacity consuming account and a processing style account). Furthermore, we manipulated the valence of the target event to investigate mood-congruency effects in prospective memory. No evidence was found for a mood-congruency effect, but the results showed that prospective memory performance increased with a sad mood. This effect is consistent with recent theories on mood-dependent processing-style regulation, postulating that a sad mood produces a more analytic and detailed processing style whereas a happy mood produces a more global and less detailed processing style.
