Facultative and inhibitory effects of location and frequency cues: Evidence of a modulation in perceptual sensitivity

摘要: The possibility that facilitative and inhibitory effects of auditory cues result because a modulation in perceptual sensitivity was examined. Listeners were presented with cue followed by target, the time period between two varied at stimulus onset asynchronies (SOAs) 150,450, or 750 msec. In conditions, target either same different location frequency. both listeners required to identify rise target. Whereas isolation, wide-band noise background such discrimination made relatively difficult. effect apparent 150-msec SOA an 750-msec for accuracy response measures performance. That these results judgment unrelated manipulated cue-target relation suggests strongly location-based frequency-based inhibition return primarily changes sensitivity.
