Hypothesis
The study aims to examine the patterns of brain activity of actors and observers elicited upon receiving feedback information of the actor's response.
Conclusion
Feedback information has a different effect on the ERP patterns of actors and observers depending on whether the actor committed an error.
Supporting Evidence
- The complexity of the task affected performance, with poorer results in more complex conditions.
- Observers showed greater brain activity when the actor made an error compared to when the actor was correct.
- The study utilized ERP measurements to analyze brain activity during the task.
Takeaway
When people act or watch someone else act, their brains respond differently, especially if the actor makes a mistake.
Methodology
Participants performed an auditory identification task in both acting and observing roles while their brain activity was recorded using ERP measurements.
Limitations
The sample size was small, and the findings need to be replicated in larger studies.
Participant Demographics
Fourteen healthy individuals (eight men and six women) with a mean age of 26.6 years.
