Hypothesis
Individual differences in attachment styles should modulate activation patterns in brain circuits known to mediate social perception and behavior.
Conclusion
The study reveals that adult attachment style modulates neural responses to the perceived social meaning of facial expressions in brain regions associated with affective processing.
Supporting Evidence
- Activation of striatum and ventral tegmental area was enhanced to positive feedback signaled by a smiling face.
- Participants with avoidant attachment showed reduced activation to social rewards.
- Anxious attachment correlated with increased amygdala response to angry faces associated with negative feedback.
Takeaway
People's attachment styles can change how their brains react to faces showing emotions, like happiness or anger, especially in social situations.
Methodology
Participants underwent fMRI while viewing faces with different emotional expressions in a social game context, and their attachment styles were assessed using questionnaires.
Potential Biases
Potential biases may arise from self-reported measures of attachment style.
Limitations
The study had a small sample size and focused only on healthy volunteers, which may limit generalizability.
Participant Demographics
16 healthy volunteers (8 males, mean age 23.6 years), all right-handed.
