In ERP studies of performance on the dichotic listening task, Hillyard and colleagues (1973) found that attended signals are accompanied by a negative-polarity waveform that is relatively large and peaks at approximately 180 milliseconds after stimulus presentation. This waveform is called the auditory ________ potential.
A)N1
B)P3
C)ERF
D)sensory

Question

Quizplus · Accepted Answer

The statement provides information about the ERP (event-related potential) waveform that is elicited in response to attended signals on the dichotic listening task. Specifically, the waveform is described as negative-polarity, relatively large, and peaking at around 180 milliseconds after stimulus presentation. This waveform corresponds to the N1 component, which is a well-established ERP component in the auditory domain that reflects the initial processing of sensory information. The other choices (B) P3, (C) ERF, and (D) sensory are either unrelated to the described waveform or not the best fit based on the information provided.
