Intensive longitudinal data was collected through theconcurrent use of a passive experience sampling (ES)smartphone application collecting objective measures ofexperience, and an ecological momentary assessment (EMA)app collecting self-reported affect. After a week-longretention interval, participants completed a memory testgenerated from paired ES and EMA data. Participants wereasked to select the GPS location at the time of a paired targetevent from four alternatives. Correct retrieval was notpredicted by self-reports grouped by negative valence/higharousal or negative valence/low arousal. Positivevalence/high arousal reported at encoding predicted greaterprobability of incorrect responses. Conversely, positivevalence/low arousal predicted greater probability of correctidentification of target. At retrieval, choice was predicted bydissimilarities in discrete emotions between target anddistractors, suggesting the use of affect as a contextualmechanism.
