    Emotion Regulation and the Experience of Future Negative Mood: The Importance of Assessing Social Support.
    (Frontiers in Psychology, 2018-01) d'Arbeloff, Tracy C; Freedy, Katherine R; Knodt, Annchen R; Radtke, Spenser R; Brigidi, Bartholomew D; Hariri, Ahmad R
    Emotion regulation refers to the use of various strategies, such as cognitive reappraisal and expressive suppression, to help manage our negative experiences, emotions, and thoughts. Although such emotion regulation often occurs within broader social dynamics and interactions, little is known about how social contexts interact with specific regulation strategies to shape the experience of negative emotions. Using data from 544 young adult university students, we provide initial evidence that habitual use of cognitive reappraisal is associated with lower future experience of depression and anxiety primarily through higher perceived social support (PSS). In contrast, expressive suppression is associated with higher future depression and anxiety primarily through lower PSS. These patterns are consistent with the importance of interpersonal influences on emotion regulation and suggest that assessment of social support can help elucidate the mechanisms of successfully regulating negative mood.

    Self-rated amygdala activity: an auto-biological index of affective distress.
    (Personality neuroscience, 2019-01) MacDuffie, Katherine E; Knodt, Annchen R; Radtke, Spenser R; Strauman, Timothy J; Hariri, Ahmad R
    Auto-biological beliefs-beliefs about one's own biology-are an understudied component of personal identity. Research participants who are led to believe they are biologically vulnerable to affective disorders report more symptoms and less ability to control their mood; however, little is known about the impact of self-originating beliefs about risk for psychopathology, and whether such beliefs correspond to empirically derived estimates of actual vulnerability. Participants in a neuroimaging study (n = 1256) completed self-report measures of affective symptoms, perceived stress, and neuroticism, and an emotional face processing task in the scanner designed to elicit threat responses from the amygdala. A subsample (n = 63) additionally rated their own perceived neural response to threat (i.e., amygdala activity) compared to peers. Self-ratings of neural threat response were uncorrelated with actual threat-related amygdala activity measured via BOLD fMRI. However, self-ratings predicted subjective distress across a variety of self-report measures. In contrast, in the full sample, threat-related amygdala activity was uncorrelated with self-report measures of affective distress. These findings suggest that beliefs about one's own biological threat response-while unrelated to measured neural activation-may be informative indicators of psychological functioning.
