Investigating solitude as a tool for downregulation of daily arousal using ecological momentary assessments

OBJECTIVE: This research explored arousal levels as a motivating factor for solitude-seeking. We hypothesized that solitude becomes more desirable when high-arousal emotions were heightened and individual differences in extraversion and neuroticism would moderate this pattern. METHOD: We tracked individuals' hourly experiences throughout a day. We assessed their high-arousal positive (e.g., excitement) and negative emotions (e.g., tension), whether they were alone or with others, and their preferred situation at the time of the signal. We gathered 4338 surveys from 362 participants, with 103 participants completing all hourly surveys. RESULTS: Preference for and incidence of solitude changed throughout the day. Contrary to our hypotheses, lagged analyses did not indicate high-arousal emotions predicting reports of being alone an hour later. However, individuals were more likely to express a preference for solitude while experiencing high-arousal negative emotions, and less so while experiencing positive emotions. Younger individuals display stronger preference for solitude during experiences of high-arousal negative emotions. Extraversion and neuroticism did not moderate these patterns. CONCLUSIONS: The results highlight the distinctive appeal of solitude as a space for young adults to deal with negative emotions. We discussed how these findings are connected to existing literature and implications for future research.
