Hypothesis
Stronger gamma band activity would be observed during subjectively reported mind wandering compared to behaviorally indexed mind wandering.
Conclusion
Subjectively reported mind wandering is associated with increased gamma band activity and greater activation in frontal brain areas compared to behaviorally indexed mind wandering.
Supporting Evidence
- Subjects reported being off-task in 32.95% of probes and on-task in 63.35%.
- Behavioral data showed a positive correlation between off-task trials and missed target trials.
- Gamma band activity was significantly higher during subjectively reported mind wandering.
Takeaway
When people daydream, their brains show more activity in certain areas than when they are just distracted. This means that daydreaming might use more brain power.
Methodology
The study used EEG to record brain activity while participants performed a vigilance task with thought sampling to assess mind wandering.
Limitations
The study's findings may need confirmation with more trials and could be influenced by the specific task used.
Participant Demographics
Eighteen healthy undergraduate and graduate students (10 males and 8 females; mean age 22.83 years).
