Abstract excerpt
OBJECTIVES: The present study was designed to investigate the association between the DRD4 genotype and auditory P300 amplitudes in a high-risk community sample.

Auditory stimuli of 60 dB HL were presented binaurally at 1000 (standard stimulus) and 2000 Hz (target stimulus), at a relative frequency...
