Auditory verbal hallucinations (AVH) are typically associated with schizophrenia but also occur in individuals without any need for care (non-clinical voice-hearers; NCVH). Cognitive models of AVH posit potential biases source-monitoring, top-down processes, or a failure to inhibit intrusive memories. However, research across clinical/non-clinical groups is limited, and the extent which there may be continuity cognitive mechanism groups, as predicted by psychosis continuum hypothesis, unclear. We report two studies voice-hearers recruited from Early Intervention Psychosis (EIP) services (n = 31) NCVH participants reporting regular spiritual voices 26) completed same task battery. Compared controls 33 28), EIP patients showed atypical signal detection, dichotic listening, memory inhibition performance, intact source-monitoring. only suggesting differences between clinical non-clinical potentially related attentional control inhibition.
