    16.3 Are Visual Motion Perception and Detection of Animacy Critical to Higher-Order Social Cognitive Function in Schizophrenia?
    (Oxford University Press, 2019-04) Johannesen, Jason; Lysaker, Paul; James, Alison; Kenney, Joshua; Bell, Morris; Medicine, School of Medicine
    Background The observation that individuals with schizophrenia tend to misinterpret subtle social cues is often attributed to deficit in Theory of Mind (ToM). While ToM is commonly assessed using videos portraying interaction between actors, recent work in vision science shows that stimuli with no innate animate features can also convey similar social information through motion alone. These simplified stimuli are advantageous for experimental purposes and may provide further insights into perceptual mechanisms supporting social cognitive function. The Social Attribution Task-Multiple Choice (SAT-MC), based on the classic Hieder and Simmel (1944) stimuli, tells a story using three geometric shapes moving about a centrally fixed figure, followed by questions about what the viewer observed. Although there are no explicit social cues, viewers typically detect actions suggestive of relationships between objects, their intentions, and emotions. This talk will present findings from three studies examining psychometric, functional, and neurophysiological aspects on SAT -MC performance in schizophrenia. Methods Study 1 examined psychometric properties of two forms of the SAT-MC in comparison to video-based social cognitive tests using human actors in 32 schizophrenia (SZ) and 30 substance use disorder (SUD) participants. Study 2 examined functional relationships of the SAT-MC and affect recognition (BLERT) performance across neurocognitive, metacognitive, ToM, and symptom domains in 72 adults with SZ. Study 3 is an in-progress investigation of neurophysiological mechanisms of social cognition using test versions adapted for EEG recording. Chronic SZ, clinical high-risk (CHR), and healthy age-matched community samples are being collected. Results SZ scored significantly lower than SUD on two versions of the SAT-MC, each classifying ~60% of SZ as impaired, compared with ~30% of SUD. The two SAT-MC forms demonstrated good test-retest and parallel form reliability, minimal practice effect, high internal consistency, similar patterns of correlation with social cognitive test performance, and compared favorably to social cognitive tests across psychometric features. When examining functional correlates of SAT -MC performance, impairment is found to co-occur with deficits in affect recognition in the majority of cases but relates uniquely to reductions in verbal memory and emotional intelligence measures. Finally, a preliminary analysis (n=8 SZ, n=2 CHR) of EEG collected during SAT-MC video presentation finds significant correlations (r=.66-.72) between occipito-parietal gamma desynchronization and task performance. Additional analyses find task-related EEG during SAT to be predictive of affect recognition (BLERT) and ToM (TASIT) performance, with correlates including alpha desynchronization in frontal, occipital, and temporal regions, and synchronization of temporal theta and occipital gamma (all r > .5). Conclusions SAT-MC performance is found to be reliable using different stimuli, related to affect recognition and ToM in three independent samples, and shows high diagnostic specificity in classifying SZ against a SUD sample. Functional correlates also involve encoding and emotional intelligence abilities tested outside the visual modality. Analysis of neural oscillatory activity related SAT-MC performance to visual and attention processes, as well as engagement of a broader social cognitive network applied to affect recognition and ToM tasks. Impairment in visual motion processing appears integral to schizophrenia pathophysiology and a critical factor influencing social cognitive abilities attributed to higher-order ToM ability.

    Group-Based Metacognitive Reflection and Insight Therapy (MERITg) and Its Relationship to Recovery-Oriented Beliefs in Serious Mental Illness
    (MDPI, 2024-06-22) Musket, Christie W.; Bullock, Joshua; Fiszdon, Joanna M.; Stacy, Meaghan; Martino, Steve; James, Alison; Lysaker, Paul H.; Schnakenberg Martin, Ashley M.; Psychiatry, School of Medicine
    Group-based Metacognitive Reflection and Insight Therapy (MERITg) is the group application of Metacognitive Reflection and Insight Therapy (MERIT), an evidence-based, integrative, recovery-oriented intervention to enhance insight and understanding of oneself and others in individuals with serious mental illness (SMI). MERITg may offer therapeutic interactions between participants that uniquely support recovery. The goal of the current study was to examine the relationship between MERITg participation and recovery-oriented beliefs. Thirty-one participants (outpatient = 21; inpatient = 10) in SMI treatment programs participated in MERITg as an adjunctive treatment. A short form of the Maryland Assessment of Recovery in Serious Mental Illness (MARS-12) was used to assess recovery-oriented beliefs before and after group participation. Recovery-oriented beliefs significantly improved in the outpatient MERITg group but not in the inpatient group, and change in recovery-oriented beliefs was positively correlated with the total number of groups attended. These findings suggest the promise of MERITg for enhancing recovery-oriented beliefs. The potential role of treatment setting is discussed.
