- Auditory evoked response
The auditory evoked response to low (0.5K Hz) and high (8.0K Hz) frequency tones at three levels of intensity (40, 55, and 80 dB) were recorded for subjects differing in degree of extra-version. Introverts were observed to have greater N1-P2 amplitude than extraverts with the low frequency tones at 55 and 80 dB intensity. The results support Eysenck's general proposal relating introversion to higher levels of cortical activity.
