Impaired Self-Other Voice Discrimination in Patients with Auditory-Verbal Hallucinations and Nonclinical Hallucination Proneness.

The hit rate is defined as the proportion of self-voice trials (signal present) correctly identified as “self.” The false alarm rate as the proportion of other-voice trials (signal absent) incorrectly identified as “self.” The miss rate as the proportion of self-voice trials identified as “other.” The correct rejection rate as the proportion of other-voice trials correctly identified as “other.” Mean d’ was lower in AVH+ ( M = 0.08) compared to controls ( M = 0.31) and AVH− ( M = 0.26), suggesting reduced perceptual sensitivity, however, this pattern did not reach statistical significance.
