Abstract

Abstract: Working memory‐based cognitive remediation therapy (CT) for psychosis has recently been associated with broad improvements in performance on untrained tasks measuring working memory, episodic memory and IQ, and changes in associated brain regions. However, it is unclear whether these improvements transfer to the domain of social cognition and neural activity related to performance on social cognitive tasks. We examined performance on the Reading the Mind in the Eyes test (Eyes test) in a large sample of participants with psychosis who underwent working memory‐based CT ( N = 43) compared to a control group of participants with psychosis ( N = 35). In a subset of this sample, we used functional magnetic resonance imaging (fMRI) to examine changes in neural activity during a facial emotion recognition task in participants who underwent CT ( N = 15) compared to a control group ( N = 15). No significant effects of CT were observed on Eyes test performance or on neural activity during facial emotion recognition, either at p < 0.05 family‐wise error or at a p < 0.001 uncorrected threshold, within a priori social cognitive regions of interest. This study suggests that working memory‐based CT does not significantly impact an aspect of social cognition which was measured behaviourally and neurally. It provides further evidence that deficits in the ability to decode mental state from facial expressions are dissociable from working memory deficits, and suggests that future CT programmes should target social cognition in addition to working memory for the purposes of further enhancing social function. Abstract : This study examined effects of a working memory‐based cognitive remediation therapy programme for psychosis on social cognition. We examined behavioural performance on a social task and neural activity during a social task (assessed using functional magnetic resonance imaging), before and after therapy. No significant effects of therapy were observed on social cognition at behavioural or neural levels, suggesting social deficits may be dissociable from working memory deficits in psychosis.
