Hypothesis
Do emotional bodily expressions enhance brain activity and functional connectivity during visual working memory tasks?
Conclusion
The study found that emotional bodily expressions increase functional connectivity between the prefrontal cortex and extrastriate body area during memory maintenance.
Supporting Evidence
- Emotional bodies elicited heightened brain activity in the left prefrontal cortex and extrastriate body area.
- Functional connectivity between the prefrontal cortex and extrastriate body area increased for happy and angry bodies compared to neutral bodies.
- Participants were able to maintain emotional bodily expressions in visual working memory.
Takeaway
When we remember how people express emotions with their bodies, our brain connects different areas to help us understand those feelings better.
Methodology
Participants performed a delayed-response task while undergoing fMRI scanning to assess brain activity and connectivity.
Limitations
The study may not generalize to other emotions and did not include EEG for complementary evidence.
