Abstract The proposed research will examine the accuracy of people’s recall of emotional states and specific events over the course of a 2-hour period. Unlike prior studies of recall over periods of this length, the current design is experimental in that participants will be presented with pre-specified patterns of stimuli allowing us to determine how various characteristics of the temporal presentation (placement of stimuli in the period and intensity of stimuli) affect recall. A series of studies are proposed that include extensive development of the experimental stimuli and pretesting of a computer-administered protocol. Techniques to construct questions that improve recall will also be developed. A final, remote-administration study of 1,000 participants will provide the data for analyses. We expect the results to be applicable to the coverage model of Ecological Momentary Assessment and similar assessment modalities.
