RESUMO

BACKGROUND: People with schizophrenia on average are more socially isolated, lonelier, have more social cognitive impairment, and are less socially motivated than healthy individuals. People with bipolar disorder also have social isolation, though typically less than that seen in schizophrenia. We aimed to disentangle whether the social cognitive and social motivation impairments observed in schizophrenia are a specific feature of the clinical condition v. social isolation generally. METHODS: We compared four groups (clinically stable patients with schizophrenia or bipolar disorder, individuals drawn from the community with self-described social isolation, and a socially connected community control group) on loneliness, social cognition, and approach and avoidance social motivation. RESULTS: Individuals with schizophrenia (n = 72) showed intermediate levels of social isolation, loneliness, and social approach motivation between the isolated (n = 96) and connected control (n = 55) groups. However, they showed significant deficits in social cognition compared to both community groups. Individuals with bipolar disorder (n = 48) were intermediate between isolated and control groups for loneliness and social approach. They did not show deficits on social cognition tasks. Both clinical groups had higher social avoidance than both community groups. CONCLUSIONS: The results suggest that social cognitive deficits in schizophrenia, and high social avoidance motivation in both schizophrenia and bipolar disorder, are distinct features of the clinical conditions and not byproducts of social isolation. In contrast, differences between clinical and control groups on levels of loneliness and social approach motivation were congruent with the groups' degree of social isolation.

RESUMO

PURPOSE: Mental health trajectories during the COVID-19 pandemic have been examined in Veterans with tenuous social connections, i.e., those with recent homelessness (RHV) or a psychotic disorder (PSY), and in control Veterans (CTL). We test potential moderating effects on these trajectories by psychological factors that may help individuals weather the socio-emotional challenges associated with the pandemic (i.e., 'psychological strengths'). METHODS: We assessed 81 PSY, 76 RHV, and 74 CTL over 5 periods between 05/2020 and 07/2021. Mental health outcomes (i.e., symptoms of depression, anxiety, contamination concerns, loneliness) were assessed at each period, and psychological strengths (i.e., a composite score based on tolerance of uncertainty, performance beliefs, coping style, resilience, perceived stress) were assessed at the initial assessment. Generalized models tested fixed and time-varying effects of a composite psychological strengths score on clinical trajectories across samples and within each group. RESULTS: Psychological strengths had a significant effect on trajectories for each outcome (ps < 0.05), serving to ameliorate changes in mental health symptoms. The timing of this effect varied across outcomes, with early effects for depression and anxiety, later effects for loneliness, and sustained effects for contamination concerns. A significant time-varying effect of psychological strengths on depressive symptoms was evident in RHV and CTL, anxious symptoms in RHV, contamination concerns in PSY and CTL, and loneliness in CTL (ps < 0.05). CONCLUSION: Across vulnerable and non-vulnerable Veterans, presence of psychological strengths buffered against exacerbations in clinical symptoms. The timing of the effect varied across outcomes and by group.

RESUMO

BACKGROUND: Mismatch negativity (MMN) is an event-related potential (ERP) component reflecting auditory predictive coding. Repeated standard tones evoke increasing positivity ('repetition positivity'; RP), reflecting strengthening of the standard's memory trace and the prediction it will recur. Likewise, deviant tones preceded by more standard repetitions evoke greater negativity ('deviant negativity'; DN), reflecting stronger prediction error signaling. These memory trace effects are also evident in MMN difference wave. Here, we assess group differences and test-retest reliability of these indices in schizophrenia patients (SZ) and healthy controls (HC). METHODS: Electroencephalography was recorded twice, 2 weeks apart, from 43 SZ and 30 HC, during a roving standard paradigm. We examined ERPs to the third, eighth, and 33rd standards (RP), immediately subsequent deviants (DN), and the corresponding MMN. Memory trace effects were assessed by comparing amplitudes associated with the three standard repetition trains. RESULTS: Compared with controls, SZ showed reduced MMNs and DNs, but normal RPs. Both groups showed memory trace effects for RP, MMN, and DN, with a trend for attenuated DNs in SZ. Intraclass correlations obtained via this paradigm indicated good-to-moderate reliabilities for overall MMN, DN and RP, but moderate to poor reliabilities for components associated with short, intermediate, and long standard trains, and poor reliability of their memory trace effects. CONCLUSION: MMN deficits in SZ reflected attenuated prediction error signaling (DN), with relatively intact predictive code formation (RP) and memory trace effects. This roving standard MMN paradigm requires additional development/validation to obtain suitable levels of reliability for use in clinical trials.

RESUMO

Auditory hallucinations, a hallmark symptom of psychosis, are experienced by most people with a diagnosis of schizophrenia at some point in their illness. Auditory hallucinations can be understood as a failure in predictive coding, whereby abnormalities in sensory/perceptual processing combine with biased cognitive processes to result in a dampening of normal prediction error signaling. In this paper, we used a roving mismatch negativity (MMN) paradigm to optimize evaluation of prediction error signaling and short-term neuroplasticity in 30 people with schizophrenia (n = 16 with and n = 14 without recent auditory hallucinations) and 20 healthy comparison participants. The recent hallucinations group exhibited an abnormal roving MMN profile [F(2,27) = 3.98, p = 0.03], significantly reduced prediction error signaling [t(28) = -2.25, p = 0.03], and a trend for diminished short-term neuroplasticity [t(28) = 1.80, p = 0.08]. There were no statistically significant differences between the healthy comparison group and the combined schizophrenia group on any of the roving MMN indices. These findings are consistent with a predictive coding account of hallucinations in schizophrenia, which posits reduced prediction error signaling in those who are prone to hallucinations. These results also suggest that plasticity-mediated formation and online updating of predictive coding models may also be disrupted in individuals with recent hallucinations.

RESUMO

OBJECTIVES: Confabulations occur in schizophrenia and certain severe neuropsychiatric conditions, and to a lesser degree in healthy individuals. The present study used a forced confabulation paradigm to assess differences in confabulation between schizophrenia patients and healthy controls. METHODS: Schizophrenia patients (n=60) and healthy control participants (n=19) were shown a video with missing segments, asked to fill in the gaps with speculations, and tested on their memory for the story. Cognitive functions and severity of symptoms were also evaluated. RESULTS: Schizophrenia patients generated significantly more confabulations than healthy control participants and had a greater tendency to generate confabulations that were related to each other. Schizophrenic confabulations were positively associated with temporal context confusions and formal thought disorder, and negatively with delusions. CONCLUSIONS: Our findings show that the schizophrenia patients generate more confabulations than healthy controls and schizophrenic confabulations are associated with positive symptoms.

RESUMO

INTRODUCTION: The auditory hallucinations associated with schizophrenia are phenomenologically diverse. "External" hallucinations classically have been considered to reflect more severe psychopathology than "internal" hallucinations, but empirical support has been equivocal. METHODS: We examined associations of "internal" versus "external" hallucinations with (1) other characteristics of the hallucinations, (2) severity of other symptoms and (3) course of illness variables, in a sample of 97 stable outpatients with schizophrenia or schizoaffective disorder who experienced auditory hallucinations. RESULTS: Patients with internal hallucinations did not differ from those with external hallucinations on severity of other symptoms. However, they reported their hallucinations to be more emotionally negative, distressing and long-lasting, less controllable and less likely to remit over time. They also were more likely to experience voices commenting, conversing or commanding. However, they also were more likely to have insight into the self-generated nature of their voices. Patients with internal hallucinations were not older, but had a later age of illness onset. CONCLUSIONS: Differences in characteristics of auditory hallucinations are associated with differences in other characteristics of the disorder, and hence may be relevant to identifying subgroups of patients that are more homogeneous with respect to their underlying disease processes.

RESUMO

Speech fundamental frequencies (SFFs) are nonverbal sound frequencies that convey emotion in speech. The degree of SFF long-term averaged spectra (LTAS) convergence between conversants reflects aspects of conversant-reported quality of the interaction (e.g., emotional synchrony). This study investigated whether SFF LTAS convergence between inpatients diagnosed with schizophrenia (n = 20) and an interviewer was associated with severity of illness (SOI), formal speech disturbance (FSD), and stress reactivity of FSD. Participants provided speech samples describing stressful and nonstressful life experiences. In the stress condition, SFF LTAS was negatively correlated with SOI and FSD. Moreover, patients exhibiting stress reactivity of FSD also evidenced stress reactivity of SFF LTAS. These findings suggest that the emotional and verbal contents of speech are disrupted by stress in schizophrenia, and SOI is associated with FSD and reduced emotional communication during stressful conditions. The interaction between stress reactivity of FSD and SFF LTAS supports the construct validity of a reactivity dimension in schizophrenia.

RESUMO

BACKGROUND: The cognitive model of negative symptoms of schizophrenia suggests that defeatist performance beliefs (DPB), or overgeneralized negative beliefs about one's performance, are an intermediary variable along the pathway from impaired neurocognitive performance to negative symptoms and functioning in daily life. Although reliable associations between these variables have been established in chronic schizophrenia, less is known about the nature of these relationships in recent-onset schizophrenia (ROSz). This current study tested the associations between DPB and variables in the cognitive model (neurocognitive performance, negative symptoms, functioning) as well as mediation by DPB of the association between neurocognitive performance and negative symptoms in ROSz. METHODS: A total of 52 participants (32 adults with ROSz and 20 non-psychiatric healthy comparators; HC) completed in-lab measures of neurocognitive performance, self-reported defeatist performance beliefs, and clinician administered measures of negative symptoms and functional outcome. Bivariate relationships among these variables were tested with Pearson correlations. Bootstrapped regression analyses were conducted to test the strength of the indirect effect of neurocognitive performance on negative symptoms through DPB. RESULTS: Defeatist performance beliefs were significantly elevated in ROSz, and were associated with neurocognitive performance, negative symptoms, and functional outcome as predicted by the cognitive model. There was a significant indirect effect of neurocognition on experiential negative symptoms through DPB, indicating DPB are a partial mediator of the relationship between neurocognitive performance and negative symptoms. CONCLUSION: These findings are consistent with the cognitive model of negative symptoms and extend previous findings in both ROSz and established schizophrenia. Specifically, these data demonstrate that DPB are elevated among ROSz and the associations with neurocognition and clinical outcomes (e.g., negative symptoms and functioning) are of similar magnitude to those reported in chronic schizophrenia. DPB may therefore be a viable treatment target in the early course of illness.

RESUMO

The COVID-19 pandemic disproportionately impacted marginalized populations including Black Americans, people with serious mental illness, and individuals experiencing homelessness. Although the double disadvantage hypothesis would suggest that individuals with multiple minoritized statuses would experience worse psychosocial impacts from the pandemic, this may not be the case for vulnerable Black Veterans. The present study investigated the sustained mental health and functional responses to the pandemic in Black and White Veterans with psychosis or recent homelessness and in a control group of Veterans enrolled in the Department of Veterans Affairs healthcare services. Clinical interviews and questionnaires were administered remotely by telephone at five time points from May 2020 through July 2021, including a retrospective time point for March 2020 (i.e., before the pandemic started). Overall, there was a striking absence of systematic differences by race in the trajectories of psychiatric symptoms and functioning among Veterans during the study period. These findings are consistent with a report on initial responses to the pandemic that revealed only a few select differences by race among Veteran groups. The lack of racial disparities is inconsistent with the double disadvantage hypothesis. Although further investigation is needed, one possible interpretation is that the wrap-around services offered by the Veterans Health Administration may have mitigated expected differences by race among Veterans with psychosis or homelessness. Future research should continue to examine whether VA services mitigate disparities in mental health and psychosocial outcomes.

RESUMO

People with schizophrenia (SCZ) and bipolar disorder (BD) have impairments in processing social information, including faces. The neural correlates of face processing are widely studied with the N170 ERP component. However, it is unclear whether N170 deficits reflect neural abnormalities associated with these clinical conditions or differences in social environments. The goal of this study was to determine whether N170 deficits would still be present in SCZ and BD when compared with socially isolated community members. Participants included 66 people with SCZ, 37 with BD, and 125 community members (76 "Community-Isolated"; 49 "Community-Connected"). Electroencephalography was recorded during a face processing task in which participants identified the gender of a face, the emotion of a face (angry, happy, neutral), or the number of stories in a building. We examined group differences in the N170 face effect (greater amplitudes for faces vs buildings) and the N170 emotion effect (greater amplitudes for emotional vs neutral expressions). Groups significantly differed in levels of social isolation (Community-Isolated > SCZ > BD = Community-Connected). SCZ participants had significantly reduced N170 amplitudes to faces compared with both community groups, which did not differ from each other. The BD group was intermediate and did not differ from any group. There were no significant group differences in the processing of specific emotional facial expressions. The N170 is abnormal in SCZ even when compared to socially isolated community members. Hence, the N170 seems to reflect a social processing impairment in SCZ that is separate from level of social isolation.

RESUMO

OBJECTIVE: Three rounds of stimulus checks were distributed to middle- and low-income U.S. adults during the COVID-19 pandemic. This 15-month longitudinal study examined rates of receipt of these stimulus checks, planned expenses, and associations with clinical outcomes among three veteran groups. METHODS: In total, 158 veterans, consisting of 59 with a psychotic disorder, 49 recently homeless veterans, and a comparison group of 50 veterans without a history of psychosis or homelessness, were assessed five times between May 2020 and July 2021. Bivariate analyses were used to compare receipt of stimulus checks and planned expenses among the groups, and multivariable analyses examined how receipt of checks was related to mental health and substance use over time. RESULTS: No group difference was found in receipt of stimulus checks, and 74%-84% of veterans reported receipt of more than one check. Most participants reported plans to use their stimulus checks to pay for bills, groceries, credit card debt, and rent or mortgage or to save the money. Over time, participants who received a greater number of stimulus checks reported significantly decreased symptoms of depression (B=-0.48) and anxiety (B=-0.84) and improved social functioning (B=0.24). For the recently homeless group, a greater number of stimulus checks received was associated with decreases in days of alcohol intoxication and drug use, but the reverse was found for the psychosis group. CONCLUSIONS: Multiple short-term unconditional government cash transfers may improve mental and social functioning among vulnerable populations during major crises, a finding that contributes to the research literature and has policy implications for pandemic and emergency preparedness.

RESUMO

The COVID-19 pandemic disproportionately impacted the physical health of some vulnerable groups, but further study is needed to investigate the pandemic's impact on financial health and mental well-being. We analyzed data from 158 participants, consisting of 59 veterans with a psychotic disorder (PSY), 49 recently housed veterans (RHV), and a control group of 50 veterans (CTL) who were assessed five times from May 2020-July 2021. This study compared the financial health of these three groups and examined the relation between financial health and psychiatric symptoms. Although the CTL group reported significantly higher income and savings than the PSY and RHV groups, the CTL group reported greater negative financial shocks than the PSY group. The RHV group reported greater material hardship but greater propensity to plan for finances and less financial shocks than the PSY group. Across all three groups, there was a reduction in financial shocks over time and no group showed more change than another. Across time, material hardship, financial shocks, and propensity to plan for finances were each significantly associated with symptoms of major depression. Together, these findings suggest the COVID-19 pandemic did not greatly impact the financial health of PSY and RHV groups possibly because of their limited income and resilience to adversity. Financial health was related to mental health supporting the U.S. government's strategic plan to include financial empowerment services in efforts to improve mental health and reduce veteran suicide.

RESUMO

Theory of mind (ToM) is an aspect of social cognition that refers to the ability to make inferences about the thoughts, feelings, and intentions of other people. It is believed to be related to social functioning. Previous investigations of ToM in schizotypy have yielded mixed results. Using a correlational approach, the present study explored the relationship between schizotypal traits, ToM, neurocognition, depressed mood, and social functioning in a sample of 50 undergraduate students. Schizotypy was related to poor social functioning. Contrary to predictions, schizotypal traits were not associated with impaired ToM. In fact, schizotypal traits were associated with enhanced performance on a ToM task that involved detection of ironic statements. However, strong relationships emerged among schizotypy, depressed mood, and social functioning, highlighting the need to also examine depression when assessing the relations between elevated schizotypy and poor social functioning.

RESUMO

The COVID-19 pandemic and social distancing have directly impacted the socioeconomic well-being of most Americans. Veterans with psychosis (PSY) and Veterans who were recently housed (RHV) through a supportive housing programme may be especially vulnerable to experiencing negative socioeconomic effects of the pandemic. In this study, we investigated socioeconomic experiences and challenges during the pandemic in these two putatively vulnerable Veteran groups and in Veterans with no history of PSY or homeless (i.e., control Veterans, CTL). A total of 231 Veterans (81 PSY, 76 RHV, 64 CTL) participated in the baseline assessment, and 203 in the follow-up assessment (74 PSY, 63 RHV, 66 CTL). At both assessment points we obtained socioeconomic information, including personal finances, financial concerns, housing concerns, experience of material hardships, and employment status. All groups of Veterans reported socioeconomic challenges during the pandemic, but the pattern of effects differed across groups. Although RHV was in a similar position to the PSY group with respect to personal finances, they reported lower levels of financial well-being and were more prone to experiencing material hardships compared to the other two groups. CTL was most vulnerable to experiencing negative financial shocks. Contrary to expectations, PSY did not experience disproportionate material hardships compared to CTL. Veterans face significant socioeconomic challenges during the COVID-19 pandemic. However, RHV disproportionately experienced certain concerns and hardships, and these are a target for intervention by clinicians and service providers. PSY generally fared better than anticipated, possibly reflecting longstanding engagement with VA services that could serve to buffer the socioeconomic impact of the pandemic.

RESUMO

The COVID-19 pandemic continues to disproportionately impact people of color and individuals experiencing psychosis and homelessness. However, it is unclear whether there are differences by race in psychosocial responses to the pandemic in vulnerable populations. The double jeopardy hypothesis posits that multiply marginalized individuals would experience worse psychosocial outcomes. The present study investigated the clinical and functional initial responses to the pandemic in both Black (n = 103) and White veterans (n = 98) with psychosis (PSY), recent homelessness (RHV), and in a control group (CTL) enrolled in Department of Veterans Affairs (VA) healthcare services. Clinical interviews were administered via phone at two time points: baseline (mid-May through mid-August 2020) and follow-up (mid-August through September 2020). The baseline interview also included retrospective measures of pre-COVID status from January 2020. There were no significant differences between Black and White veterans in depression, anxiety, or loneliness. However, Black veterans did endorse more fears of contamination, F(1, 196.29) = 9.48, p = .002. Across all groups, Black veterans had better family integration compared to White veterans, F(1, 199.98) = 7.62, p = .006. There were no significant differences by race in social integration, work/role productivity, or independent living. In sum, there were few significant differences between Black and White veterans in initial psychosocial response to the pandemic. The lack of racial disparities might reflect the presence of VA's wrap-around services. The findings also highlight the robust nature of social support in Black veterans, even in the context of a global pandemic. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

RESUMO

BACKGROUND: The COVID-19 pandemic has had unprecedented effects on mental health and community functioning. Negative effects related to disruption of individuals' social connections may have been more severe for those who had tenuous social connections prior to the pandemic. Veterans who have recently experienced homelessness (RHV) or have a psychotic disorder (PSY) are considered particularly vulnerable because many had poor social connections prior to the pandemic. METHODS: We conducted a 15-month longitudinal study between May 2020 -July 2021 assessing clinical (e.g., depression, anxiety) and community (e.g., social functioning, work functioning) outcomes. Eighty-one PSY, 76 RHV, and 74 Veteran controls (CTL) were interviewed over 5 assessment periods. We assessed changes in mental health and community functioning trajectories relative to pre-pandemic retrospective ratings and examined group differences in these trajectories. RESULTS: All groups had significantly increased symptoms of depression, anxiety, and concerns with contamination at the onset of the pandemic. However, RHV and PSY showed faster returns to their baseline levels compared to CTL, who took nearly 15 months to return to baseline. With regards to functioning, both RHV and PSY, but not CTL, had significant improvements in family and social networks over time. Work functioning worsened over time only in PSY, and independent living increased over time in both RHV and PSY but not CTL. CONCLUSIONS: These results reveal that vulnerable Veterans with access to VA mental health and case management services exhibited lower negative impacts of the COVID-19 pandemic on mental health and community functioning than expected.

RESUMO

Reality monitoring, or the ability to discriminate internal from external information present in short-term memory, is relevant in the study of schizophrenia. Previous research has linked monitoring impairments with psychotic symptoms and certain forms of communication disturbance. The focus of the present study was to test the hypothesis that there would be specific relationships between reality monitoring in patients with schizophrenia and current and pre-morbid social functioning, beyond the effects of general verbal ability. Fifty outpatients with schizophrenia or schizoaffective disorder were assessed for internal/external reality monitoring deficits, general verbal intelligence, and both current and pre-morbid social functioning. Associations between these variables were assessed. Exploratory analyses also were conducted to determine whether specific types of reality monitoring errors were related to social functioning. Results showed that (a) overall accuracy in reality monitoring was related to pre-morbid social functioning beyond the effects of verbal ability, (b) sensitivity to old versus new information in reality monitoring was related to current social functioning, and (c) a say-report-think reality monitoring error was significantly associated with pre-morbid social functioning. The results support the hypothesis of an association between reality monitoring sensitivity and social functioning.

RESUMO

Studies have found higher levels of alexithymia in schizophrenic subjects relative to controls, with an overall higher level of emotional arousal and social withdrawal. The present study is an extension of this research to the assessment of schizotypy in a nonclinical sample. Seventy-two undergraduate students (40 female; 21.6 ± 6.38 years) were recruited to participate in this study. Consistent with earlier research, our results show that both schizotypy and alexithymia are associated with relatively poor socioemotional functioning across the variables of depression, anxiety, social functioning, and overall quality of life. Further, our results show that the significant associations found between alexithymia and these 4 outcome variables was predicated on shared variance with schizotypy. When both alexithymia and schizotypy were regressed onto these variables as independent predictors, the contribution of alexithymia was consistently nonsignificant. The implications of these findings are discussed in terms of hypothesized substrates of alexithymia.

RESUMO

The COVID-19 pandemic has upended the lives of everyone in the United States, negatively impacting social interactions, work, and living situations, and potentially exacerbating mental health issues in vulnerable individuals. Within the Department of Veterans Affairs (VA) healthcare system, two vulnerable groups include those with a psychotic disorder (PSY) and those who have recently experienced homelessness (recently housed Veterans, RHV). We conducted phone interviews with PSY (n = 81), RHV (n = 76) and control Veterans (CTL, n = 74) between mid-May - mid-August 2020 ("initial") and between mid-August - mid-October 2020 ("follow-up"). At the initial period, we also collected retrospective ratings relative to January 2020 ("pre-COVID-19"). We assessed clinical factors (e.g., depression, anxiety, loneliness) and community integration (e.g., social and role functioning). All groups reported worse clinical outcomes after the onset of the COVID-19 pandemic. However, PSY and RHV exhibited improvements in depression and anxiety from initial to follow up, whereas CTL continued to exhibit elevated levels. There was little change in community integration measures. Our results indicate that all groups reported increased mental health problems after the onset of the pandemic, but vulnerable Veterans were not disproportionately affected and had better mental health resilience (i.e., for depression and anxiety) as the pandemic progressed compared to CTL. This effect could be due to the availability and utilization of VA services for PSY and RHV (e.g., housing and financial support, medical and mental health services), which may have helped to mitigate the impact of the pandemic.

RESUMO

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 [r EmoBio = 0.45, p < 0.01; r TASIT = 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.
