Everyday life unfolds continuously, but somehow our memories are more discrete and episodic, broken down into individual memories or events. Increasing research suggests that continuity and change in an unfolding context (e.g., spatial location) promotes the transformation of ongoing experiences into distinct and memorable events (Clewett et al., 2019). To date, much of the research on this idea has focused on how stability and change in the external environment (e.g., remaining within a room and then crossing into a new one) affects the organization of episodic memory. But everyday life is also heavily colored by dynamic fluctuations in emotional experiences and moods. Somewhat surprisingly, even though it is well established that emotional stimuli have an especially strong influence on cognitive processing, little work has taken a holistic approach to understanding how emotion simultaneously impacts the multi-faceted elements of memory (e.g., space, time, perceptual features, subjective feelings; see Clewett and Murty, 2019; Palombo and Cocquyt, 2020). The goal of this study is to examine how music induces discrete and lingering effects on emotional states, and how these mood fluctuations in turn affect different aspects of memory for temporally-extended sequences. Recent evidence shows that fluctuations in arousal states, as indexed by pupil size and dilation, predict the temporal integration of sequential information in memory (Clewett et al., 2020). This suggests that dynamic musical pieces and the moods they induce can influence how information is integrated together. Another possibility is that emotional stimuli function as especially strong context shifts during dynamic experiences, because they elicit much more robust increases in arousal than neutral information (Clewett et al., 2020). Motivated by these findings, we plan to investigate how emotional states that unfold during neutral item sequences elicit discrete and sustained effects on encoding temporal, perceptual, and event information. Specifically, we will examine how emotional contexts, elicited through controlled-musical stimuli, influence different aspects of episodic memory representations, including memory for temporal order, temporal distance, individual items representations, and temporal source context.
