According to constructivist theories of emotion, members of different populations experience emotion differently as a result of assembling different neural resources to produce it. To test this prediction, we sampled individuals from three populations (experienced meditators, cancer survivors, matched controls) and used functional magnetic resonance imaging (fMRI) to assess their neural responses to four kinds of affective phrases (positive cancer, negative cancer, positive non-cancer, negative noncancer). As predicted, the three populations responded differently to these affective phrases. When assessing neural activity for positive vs. negative phrases, controls showed the standard negativity bias reported in the emotion literature, cancer survivors showed a positivity bias (perhaps related to personal growth following cancer), and experienced meditators showed no bias (perhaps reflecting the mental quality of equanimity established through regular meditation practice). When assessing neural activity for positively-valenced cancer vs. non-cancer phrases, controls exhibited difficulty engaging with the cancer phrases, engaging much more with the non-cancer phrases instead. In contrast, experienced meditators and cancer survivors engaged more with the cancer phrases, while exhibiting different affective styles. Together these results indicate that experienced meditators, cancer survivors, and matched controls assemble different neural resources to process emotion.Keywords: emotion, constructivist theory, grounded cognition, meditators, cancer patients
Population Differences in Emotion 3According to constructivist theories of emotion, an emotional state results from assembling perceptual, cognitive, interoceptive, and motor resources relevant for comprehending an emotional situation and coping with it effectively (Barrett, 2006a(Barrett, , 2006bGendron & Feldman Barrett, 2009;Wilson-Mendenhall, Barrett, Simmons, & Barsalou, 2011). To see how this account works, imagine that a distressed man enters your workplace, and begins firing a gun wildly in the air. According to constructivist theories, perceptual processes enable you to recognize that a distressed person and a gun are present; cognitive processes indicate that you and others are threatened, anticipating the potential implications; your body might become aroused to the point of panic, with your heart racing and breath catching; your motor system might freeze initially and then prepare to flee. From the constructivist perspective, your brain has activated neural resources that are well suited for understanding and coping with this particular emotional situation. As a result of all these processes becoming active and assembled together coherently, they produce one of many possible states of fear. Now imagine instead that, on previous occasions, you practiced assembling a different set of neural resources in this type of situation. For example, your employer might have provided you with training on how to coolly handle such situations in your workplace...
