Hillyard and Colleagues (1973) Recorded Event-Related Potentials (ERP) from Participants

Hillyard and colleagues (1973) recorded event-related potentials (ERP) from participants while they performed a dichotic listening task. When comparing the ERPs collected when participants attended to a given signal to those collected when they ignored this signal, the researchers found that auditory ERPs

A) began later for attended versus unattended signals.
B) began earlier for attended versus unattended signals.
C) were larger for attended versus unattended signals.
