“…Barta et al [47] observed that PS deviated further to the right with respect to the control group when they (1) bisected lines placed on the right side of the page and (2) when they used the right hand and the direction of scanning was from right to left. The presence of a rightward bias was subsequently confirmed by Rao et al [48] and Benson and Park [49]. Also in the study by Rao et al [48] participants used the left or right hand.…”

“…Other Authors [49,50] have proposed that the left hemispatial inattention present in schizophrenia would implicate an impairment of the right parietal control of spatial attention. This hypothesis was supported by previous literature implicating right parietal abnormalities in schizophrenia [57][58][59][60][61].…”

“…The relationship between bisection performance and clinical profile of PS with left hemi-inattention was investigated, performing correlations between bisection errors and Positive And Negative Syndrome Scale [47,49], Brief Psychiatric Rating Scale [49] and Delusions Inventory [49] scores. Barnett [47] found that individuals with greater overall negative symptomatology made greater rightward deviations in right hemispace.…”

Journal of Psychiatry AbstractAsymmetries of visuospatial attention has long been described in hemispatial neglect, a neurological syndrome in which brain damaged patients fail to acknowledge or explore stimuli presented to the contralesional side of space. Asymmetries for spatial attention were also investigated in schizophrenia. In this review, we report the researches that, using tasks selectively employed to study visuospatial processing in neglect patients, demonstrated hemineglect-like behaviour in schizophrenia. Intriguingly, these studies produced mixed evidence. Some researches found biases towards the left hemispace suggesting a right hemineglect, others towards the right hemispace suggesting a left hemineglect. We examine the possible factors that may have contributed in producing these conflicting findings.

“…For all of the individual B-BODI pictures, we predicted that participants with schizophrenia would endorse significantly more items, and also score higher on frequency, distress, and vividness (intensity) as a result of having these experiences more often (contributing to the frequency score), feeling as if they were stressful (contributing to the distress score), and imagining them more vividly (e.g., based on the findings of enhanced imagery in individuals with schizophrenia; Benson & Park, 2013; contributing to the vividness score). The same hypothesis and predictions were made for individuals at increased risk for schizophrenia compared to those at lower risk.…”

Bodily self‐disturbance in schizophrenia‐spectrum populations: Introducing the Benson et al. Body Disturbances Inventory (B‐BODI)

Anomalous or weakened sense of self was central to early theories of schizophrenia. Recent studies have also documented disturbances in body ownership and increased susceptibility for dissociative experiences, such as the out-of-body experience in individuals with schizophrenia, but further research is necessary to clarify components of bodily self-disturbances in the schizophrenia spectrum, and the stability of these experiences over time. With respect to methodology, self-disturbances research in schizophrenia tends to rely exclusively on verbal self-report questionnaires and interviews. Given that individuals with schizophrenia suffer from language and communication difficulties, verbal self-report measures may be insufficient. To bridge this gap, we have developed a new picture-based instrument, the Benson et al. Body Disturbances Inventory (B-BODI), designed to quantify bodily self-disturbances with respect to the frequency and vividness of these experiences, as well as the degree of distress associated with them. Drawings that depicted different aspects of aberrant bodily self-experiences were presented with accompanying captions. Participants were asked to indicate the frequency, vividness, and distressfulness of the experience captured by the picture using a 5-point scale. Individuals with schizophrenia, older healthy controls, and college students participated in two alternative versions of the B-BODI. Participants were also asked to complete a battery of established questionnaires that probed psychosis proneness and a range of self, body, and perceptual aberrations. The results suggest that the B-BODI is a useful tool that accurately captures bodily self-disturbances and has the potential to predict psychosis risk in healthy young individuals. Furthermore, anomalous self-disturbances seem to be relatively stable across time in individuals with chronic schizophrenia.
