ABSTRACT Deficits in emotional processing have been widely described in schizophrenia. Associations of positive symptoms with poor emotional prosody comprehension (EPC) have been reported at the phenomenological, behavioral, and neural levels. This review focuses on the relation between emotional processing deficits and auditory verbal hallucinations (AVH). We explore the possibility that the relation between AVH and EPC in schizophrenia might be mediated by the disruption of a common mechanism intrinsic to auditory processing, and that, moreover, prosodic feature processing deficits play a pivotal role in the formation of AVH. The review concludes with proposing a mechanism by which AVH are constituted and showing how different aspects of our neuropsychological model can explain the constellation of subjective experiences which occur in relation to AVH.

    • "It is well established that individuals with schizophrenia (SZ) have deficits in social cognition, with the most severe deficits in the domains of emotion perception (Kohler and Brennan, 2004; Kohler et al., 2010; Salva et al., in press). Deficits in emotion perception have been found across a range of basic emotions in tasks requiring labeling, discrimination, and matching across auditory, visual, and combined audio-visual sensory modalities (de Gelder et al., 2005; Martin et al., 2005; de Jong et al., 2009; Strauss et al., 2010; Combs et al., 2011; Salgado-Pineda et al., 2011; Alba-Ferrara et al., 2012; Gold et al., 2012; Surguladze et al., 2012). Impairments in processing neutral or ambiguous facial stimuli are also well-documented, and analyses of error types made to neutral facial stimuli have indicated that individuals with SZ are more likely to misattribute negative emotions to neutral stimuli (Hooker et al., 2011; Pinkham et al., 2011).

    ABSTRACT: Emotion perception deficits are a well-established feature of schizophrenia (SZ). Individuals with SZ have difficulty labeling emotional stimuli across auditory, visual, and audio-visual modalities and also misattribute threat towards neutral stimuli. The relationship between a history of psychosis and similar abnormalities in bipolar disorder (BD) is less clear. The current study set out to examine emotion perception across sensory modalities in a sample of 24 stabilized individuals meeting criteria for SZ, 24 remitted individuals meeting criteria for BD with psychotic features, 24 remitted individuals meeting criteria for BD without psychotic features, and 24 healthy controls. Results indicated that the bipolar with psychotic features group had intermediary performance between the SZ group and the other two groups for auditory, visual, and audio-visual items, with particularly poor performance in identifying angry stimuli. The SZ group misattributed neutral stimuli as negative when they were in visual format, but as positive when they were in auditory or audio-visual formats. The bipolar with psychotic features group had a trend towards misattributing more neutral visual stimuli as negative. These findings indicate that emotion perception deficits are present in BD with psychotic features and comparatively spared in BD without psychotic features, and that a similar bias of misattributing negative emotions to neutral visual stimuli may be present across diagnostic boundaries.

    ABSTRACT: Cognitive models propose that auditory verbal hallucinations arise through inner speech misidentification. However, such models cannot explain why the voices in hallucinations often have identities different from the hearer. This study investigated whether a general voice identity recognition difficulty might be present in schizophrenia and related to auditory verbal hallucinations. Twenty-five schizophrenia patients and 13 healthy controls were tested on recognition of famous voices. Signal detection theory was used to calculate perceptual sensitivity and response criterion measures. Schizophrenia patients obtained fewer hits and had lower perceptual sensitivity to detect famous voices than healthy controls did. There were no differences between groups in false alarm rate or response criterion. A symptom-based analysis demonstrated that especially those patients with auditory verbal hallucinations performed poorly in the task. The results indicate that patients with hallucinations are impaired at voice identity recognition because of decreased sensitivity, which may result in inner speech misidentification.

    ABSTRACT: Recent findings have demonstrated that emotional prosody (EP) attracts attention involuntarily (Grandjean et al., 2008). The automat shift of attention toward emotionally salient stimuli can be overcome by attentional control (Hahn et al., 2010). Attentional control is impaired in schizophrenia, especially in schizophrenic patients with hallucinations because the “voices” capture attention increasing the processing load and competing for top-down resources. The present study investigates how involuntary attention is driven by implicit EP in schizophrenia with auditory verbal hallucinations (AVH) and without (NAVH). Fifteen AVH patients, 12 NAVH patients and 16 healthy controls (HC) completed a dual-task dichotic listening paradigm, in which an emotional vocal outburst was paired with a neutral vocalization spoken in male and female voices. Participants were asked to report the speaker's gender while attending to either the left or right ear. NAVH patients and HC revealed shorter response times for stimuli presented to the attended left ear than the attended right ear. This laterality effect was not present in AVH patients. In addition, NAVH patients and HC showed faster responses when the EP stimulus was presented to the unattended ear, probably because of less interference between the attention-controlled gender voice identification task and involuntary EP processing. AVH patients did not benefit from presenting emotional stimuli to the unattended ear. The findings suggest that similar to HC, NAVH patients show a right hemispheric bias for EP processing. AVH patients seem to be less lateralized for EP and therefore might be more susceptible to interfering involuntary EP processing; regardless which ear/hemisphere receives the bottom up input.
