Using the Muse Headset to Measure the N400 Effect
Author Information
Author(s): Hannah Begue, Cyrille Magne
Primary Institution: Middle Tennessee State University
Hypothesis
The Muse 2 headset is sufficiently sensitive to capture the N400 effect in a semantic relatedness judgment task.
Conclusion
The Muse 2 can reliably measure the N400 effect, indicating its potential as a valuable tool for language research.
Supporting Evidence
- The N400 effect was significantly larger for unrelated word pairs compared to related ones.
- High accuracy rates in the semantic relatedness judgment task indicated participant engagement.
- The Muse 2 demonstrated acceptable internal consistency for the N400 data.
Takeaway
The Muse 2 headset can help researchers study how our brains understand words, making it easier for more people to participate in brain research.
Methodology
Participants evaluated the semantic relatedness of word pairs while their EEG was recorded using the Muse 2, and single-trial ERPs were analyzed using robust Yuen t-tests and hierarchical linear modeling.
Potential Biases
Potential signal quality and noise reduction limitations inherent in consumer-grade EEG devices.
Limitations
The Muse 2 has a limited number of electrodes, which may affect the ability to localize brain activity precisely.
Participant Demographics
Primarily first-year college students, with a mean age of 19.95 years; 51.35% female; diverse racial and ethnic backgrounds.
