Evaluating Optimal Arousal Level during the Task Based on Performance and Positive Mood: Extracting Indices Reflecting the Relationship among Arousal, Performance, and Mood

Trait level somatic arousal modulates fMRI neural synchrony to naturalistic stimuli

“…Most of the literature surrounding somatic arousal focuses on acute symptoms (Satpute et al, 2019; Fan et al, 2015), rather than as a trait in which some individuals are more likely to have more pronounced somatic arousal responses. Furthermore, studies investigating somatic arousal tend to use sparse tasks, such as viewing emotional photos (Hillman et al, 2004) or completing memory tasks (Sawai et al, 2015), and behavioural measures of somatic arousal, such as measuring heart rate variability (Graham et al, 2000). However, simple, sparse tasks, such as photo viewing and memory tasks, do not reflect the complexity of stimuli encountered in real-life.…”
