<p>Emotion and age modulate episodic memory. In both young and older adults, emotion has a beneficial effect on item memory, with an advantage for positive vs. negative stimuli in older adults. In young adults, emotion has also been shown to enhance memory for intrinsic item features (e.g., temporal memory), but to degrade memory for contextual/extrinsic information. How emotion affects memory for these components in older adults is less clear, as findings are mixed. Small sample sizes are at least partly responsible for these heterogeneous results. Therefore, the aim of this study is to simultaneously investigate how age modulates the effect of positive vs. negative emotion on 1) item memory (what?), 2) temporal memory (when?), and 3) associative memory between items and their extrinsic context (in which context?). To this end, we will extend the paradigm developed by Palombo et al. (2021) by including combinations of negative, neutral, and positive images and neutral videos, and compare younger and older adults on image memory, temporal positioning of images in videos, and association between images and videos. In order to guarantee a satisfactory statistical power while potentially reducing the cost of the experimental runs, we will conduct sequential statistical analyses in three time points (time 1: 75 younger vs. 75 older adults; time 2: 113 younger vs. 113 older adults; time 3: 150 younger vs. 150 older adults).</p>
