early Visual Processing is associated with social cognitive performance in recent onset schizophrenia
Frontiers in Psychiatry, 2020Co-Authors: Amanda Mccleery, Keith H Nuechterlein, Michael F Green, Jonathan K. Wynn, Junghee Lee, Eric A. Reavis, Joseph Ventura, Kenneth L. SubotnikAbstract:Background Early-stage Visual Processing deficits are evident in chronic schizophrenia. Consistent with a cascade model of information Processing, whereby early perceptual processes have downstream effects on higher-order cognition, impaired Visual Processing is associated with deficits in social cognition in this clinical population. However, the nature of this relationship in the early phase of illness is unknown. Here, we present data from a study of early Visual Processing and social cognitive performance in recent-onset schizophrenia (ROSz). Method Thirty-two people with ROSz and 20 healthy controls (HC) completed a Visual backward masking task using stimuli of real world objects (Object Masking) to assess early-stage (i.e., 0-125 ms post-stimulus onset) Visual Processing. Subjects also completed two tasks of social cognition, one assessing relatively low-level processes of emotion identification (Emotion Biological Motion, EmoBio), and another assessing more complex, higher-order theory of mind abilities (The Awareness of Social Inference Test, TASIT). Group differences were tested with repeated measures ANOVAs and t-tests. Bivariate correlations and linear regressions tested the strength of associations between early-stage Visual Processing and social cognitive performance in ROSz. Results For Object Masking, the mask interfered with object identification over a longer interval for ROSz than for HC [F (3.19, 159.35) = 8.51, p < 0.001]. ROSz were less accurate on the EmoBio task [t (50) = -3.36, p = 0.001] and on the TASIT compared to HC [F (1, 50) = 38.37, p < 0.001]. For the TASIT ROSz were disproportionately impaired on items assessing sarcasm detection [F (1, 50) = 4.30, p = 0.04]. In ROSz, better Object Masking performance was associated with better social cognitive performance [rEmoBio = 0.45, p < 0.01; rTASIT = 0.41, p < 0.02]. Regression analyses did not provide significant support for low-level social cognition mediating the relationship between Visual Processing and high-level social cognition. Conclusion Early-stage Visual Processing, low-level social cognition, and high-level social cognition were all significantly impaired in ROSz. Early-stage Visual Processing was associated with performance on the social cognitive tasks in ROSz, consistent with a cascade model of information Processing. However, significant cascading effects within social cognition were not supported. These data suggest that interventions directed at early Visual Processing may yield downstream effects on social cognitive processes.

Early Visual Processing Is Associated With Social Cognitive Performance in Recent-Onset Schizophrenia

Cross-diagnostic comparison of Visual Processing in bipolar disorder and schizophrenia.
Journal of psychiatric research, 2014Co-Authors: Carol Jahshan, Amanda Mccleery, Jonathan K. Wynn, David C. Glahn, Lori L. Altshuler, Michael F GreenAbstract:Abstract Patients with Schizophrenia (SZ) show deficits across various stages of Visual information Processing. Whether patients with Bipolar Disorder (BD) exhibit these deficits is unclear. In this study, we conducted a detailed comparison of specific stages of early Visual perception in BD and SZ. Forty-three BD patients, 43 SZ patients, and 51 matched healthy control subjects (HC) were administered three Visual Processing paradigms emphasizing: 1) an early stage of object formation (location backward masking), 2) a middle stage of object substitution (four-dot backward masking), and 3) a later stage at the perception–attention interface (rapid serial Visual Processing (RSVP) task eliciting the attentional blink). SZ performed significantly worse than BD and HC on location and four-dot masking. BD did not significantly differ from HC on either masking task. Both patient groups performed significantly worse than HC on the RSVP task; unlike SZ, BD did not show a significant attentional blink effect compared to HC. Our results indicate that BD patients were intact at the early and middle stages of Visual Processing (object formation and substitution) but intermediate between the SZ and HC groups at a later Processing stage involving perceptual and attentional processes (RSVP task). These findings suggest that SZ is characterized by a diffuse pathophysiology affecting all stages of Visual Processing whereas in BD disruption is only at the latest stage involving higher order attentional functions.

Social perception and early Visual Processing in schizophrenia.
Schizophrenia research, 2003Co-Authors: Mark J Sergi, Michael F GreenAbstract:Persons with schizophrenia experience deficits in social cognition-the cognitive processes involved in how people perceive and interpret information about themselves, others, and social situations. These deficits may be related to the neurocognitive impairments often experienced by persons with schizophrenia. Our primary objective was to examine associations between social perception and early Visual Processing in schizophrenia. Our secondary objective was to examine whether outpatients with schizophrenia and healthy persons differ in social perception. Forty outpatients with schizophrenia and 30 healthy persons completed a measure of social perception (the Half-Profile of Nonverbal Sensitivity), Visual masking procedures, and ratings of positive and negative symptoms. Within patients, performance on Visual masking procedures was related to performance on the Half-Profile of Nonverbal Sensitivity. Patients with schizophrenia and the healthy persons differed significantly in their performance on the Half-Profile of Nonverbal Sensitivity, but this difference became nonsignificant when education was a covariate. These findings suggest that social perception in schizophrenia is related to very early aspects of Visual Processing.

The role of Visual Processing speed in reading speed development.
PLoS ONE, 2013Co-Authors: Muriel Lobier, Matthieu Dubois, Sylviane ValdoisAbstract:A steady increase in reading speed is the hallmark of normal reading acquisition. However, little is known of the influence of Visual attention capacity on children's reading speed. The number of distinct Visual elements that can be simultaneously processed at a glance (dubbed the Visual attention span), predicts single-word reading speed in both normal reading and dyslexic children. However, the exact processes that account for the relationship between the Visual attention span and reading speed remain to be specified. We used the Theory of Visual Attention to estimate Visual Processing speed and Visual short-term memory capacity from a multiple letter report task in eight and nine year old children. The Visual attention span and text reading speed were also assessed. Results showed that Visual Processing speed and Visual short term memory capacity predicted the Visual attention span. Furthermore, Visual Processing speed predicted reading speed, but Visual short term memory capacity did not. Finally, the Visual attention span mediated the effect of Visual Processing speed on reading speed. These results suggest that Visual attention capacity could constrain reading speed in elementary school children.
