“…Within emotion recognition for instance, some studies have reported an advantage for paranoid individuals rather than non-paranoid individuals (e.g. (Chan et al, 2008; Van’t Wout et al, 2007), thus raising questions about the true nature of the effect. We explored this specific issue in an earlier investigation and found that paranoid and non-paranoid patients did not differ in overall emotion recognition ability but that paranoid patients displayed a tendency to over attribute anger to neutral expressions (Pinkham et al, 2011a).…”

Paranoia is a common symptom of schizophrenia that may be related to how individuals process and respond to social stimuli. Previous investigations support a link between increased paranoia and greater social cognitive impairments, but these studies have been limited to single domains of social cognition, and no studies have examined how paranoia may influence functional outcome. Data from 147 individuals with schizophrenia were used to examine whether actively paranoid and non-paranoid individuals with schizophrenia differ in social cognition and functional outcomes. On measures assessing social cognitive bias, paranoid individuals endorsed more hostile and blaming attributions and identified more faces as untrustworthy; however, paranoid and non-paranoid individuals did not differ on emotion recognition and theory of mind tasks assessing social cognitive ability. Likewise, paranoid individuals showed greater impairments in real-world interpersonal relationships and social acceptability as compared to non-paranoid patients, but these differences did not extend to performance based tasks assessing functional capacity and social competence. These findings isolate specific social cognitive disparities between paranoid and non-paranoid subgroups and suggest that paranoia may exacerbate the social dysfunction that is commonly experienced by individuals with schizophrenia.

“…Deficits in facial affect recognition and vocal prosody in schizophrenia correlate with each other and with poor social functioning (Kucharska-Pietura et al 2005, Hooker and Park 2002). In stable patients, the deficit is less severe in paranoid compared to non-paranoid subtypes of schizophrenia (Chan et al 2008). In acute inpatients, the deficit in prosody recognition is greater in patients with auditory hallucinations compared to those without auditory hallucinations (Rossell and Boundy 2005).…”

Involvement of the insular cortex is a common finding in neuroanatomical studies of schizophrenia, yet its contribution to disease pathology remains unknown. This review describes the normal function of the insula and examines pathology of this region in schizophrenia. The insula is a cortical structure with extensive connections to many areas of the cortex and limbic system. It integrates external sensory input with the limbic system and is integral to the awareness of the body's state (interoception). Many deficits observed in schizophrenia involve these functions and may relate to insula pathology. Furthermore, reports describing deficits caused by lesions of the insula parallel deficits observed in schizophrenia. Examples of insula-related functions that are altered in schizophrenia include the processing of both visual and auditory emotional information, pain, and neuronal representations of the self. The last of these functions, processing representations of the self, plays a key role in discriminating between self-generated and external information, suggesting that insula dysfunction may contribute to hallucinations, a cardinal feature of schizophrenia.

“…Previous investigations of the influence of paranoia on facial affect recognition in schizophrenia have provided conflicting results. Some studies support an advantage for paranoid over non-paranoid patients (Chan et al 2008; Davis and Gibson 2000; Lewis and Garver 1995; Phillips et al 1999; Van't Wout et al 2007), while others show the opposite pattern (An et al 2006; Russell et al 2007; Williams et al 2007). Kline and colleagues (1992) note that this pattern may differ based on emotion, as their work showed that paranoid patients were more accurate for negative emotions but that groups did not differ in correctly labeling positive emotions.…”

“…Perhaps most importantly, many previous studies have defined the paranoid and non-paranoid subgroups based on diagnostic subtype rather than symptom ratings at the time of testing (An et al 2006; Chan et al 2008; Davis and Gibson 2000; Lewis and Garver 1995; Van't Wout et al 2007). It is important to note that under DSM-IV-TR, patients do not require persecutory or paranoid delusions to be diagnosed with this subtype.…”

Previous investigations of the influence of paranoia on facial affect recognition in schizophrenia have been inconclusive as some studies demonstrate better performance for paranoid relative to non-paranoid patients and others show that paranoid patients display greater impairments. These studies have been limited by small sample sizes and inconsistencies in the criteria used to define groups. Here, we utilized an established emotion recognition task and a large sample to examine differential performance in emotion recognition ability between patients who were actively paranoid (AP) and those who were not actively paranoid (NAP). Accuracy and error patterns on the Penn Emotion Recognition test (ER40) were examined in 132 patients (64 NAP and 68 AP). Groups were defined based on the presence of paranoid ideation at the time of testing rather than diagnostic subtype. AP and NAP patients did not differ in overall task accuracy; however, an emotion by group interaction indicated that AP patients were significantly worse than NAP patients at correctly labeling neutral faces. A comparison of error patterns on neutral stimuli revealed that the groups differed only in misattributions of anger expressions, with AP patients being significantly more likely to misidentify a neutral expression as angry. The present findings suggest that paranoia is associated with a tendency to over attribute threat to ambiguous stimuli and also lend support to emerging hypotheses of amygdala hyperactivation as a potential neural mechanism for paranoid ideation.
