Self-Reported Trait Mindfulness and Affective Reactivity: A Comprehensive Investigation of Valence, Arousal, and Attention to Emotional Pictures

Sammanfattning: Mindful attention is qualitatively receptive and non-reactive, and is thought to facilitate adaptive emotional responding. Using a multi-method approach, I studied the relationship between individual differences in self-reported trait mindfulness and electrocortical, electromyographic, electrodermal, and self-reported responses to emotional pictures. Specifically, while subjects passively viewed IAPS pictures, electrocortical data, skin conductance, and also electromyographic data were recorded. Afterwards, subjects rated their subjective valence and arousal while viewing the pictures again. If trait mindfulness reduces general emotional responding, then responses from individuals with high mindfulness would be associated with decreased late positive potential amplitudes, decreased skin conductance response, and decreased subjective ratings of valence and arousal to emotional pictures. High mindfulness would also be associated with a decreased emotional modulation of startle eyeblink amplitudes and of startle P3 amplitudes during emotional pictures. Although analysis showed clear effects of emotion on dependent measures, in general, mindfulness did not moderate these effects.
