Improved facial affect recognition in patients with first-episode psychosis

Facial emotion identification impairments in Chinese persons living with schizophrenia: A meta-analysis

BACKGROUND

Facial emotion identification (FEI) deficits are associated with impaired social functioning in persons living with schizophrenia (PLwS), but the research on emotion-specific FEI deficits remains inconclusive. Furthermore, existing studies on FEI deficits are limited by their small sample sizes. We performed a meta-analysis of studies comparing the FEI abilities between Chinese PLwS and healthy controls in terms of the six basic facial emotions (happiness, sadness, fear, disgust, anger, and surprise), as well as contempt, calmness, and neutral facial expressions.

METHODS

Major Chinese- and English-language databases were searched to retrieve case-control studies that compared the FEI task performance between Chinese PLwS and healthy controls (HCs) and reported the emotion-specific correct identification scores for PLwS and HCs. The Joanna Briggs Institute Critical Appraisal Checklist for Case-control Studies ("JBI checklist," hereafter) was used to assess the risk of bias (RoB) of the included studies. Statistical analysis was performed using the "meta" package of R 4.1.2.

RESULTS

Twenty-three studies with a total of 28 case-control cohorts and 1,894 PLwS and 1,267 HCs were included. The RoB scores of the included studies ranged from two to seven. PLwS had statistically significantly lower FEI scores than HCs and the corresponding emotion-specific pooled standard mean differences (95% confidence intervals) were -0.69 (-0.88, -0.50) for happiness, -0.88 (-1.12, -0.63) for sadness, -1.44 (-1.83, -1.06) for fear, -1.18 (-1.60, -0.76) for disgust, -0.91 (-1.24, -0.57) for anger, -1.09 (-1.39, -0.78) for surprise, -0.26 (-0.51, -0.01) for contempt, -0.31 (-0.52, -0.09) for calmness, and -0.42 (-0.65, -0.18) for neutral. In the analyses of sources of heterogeneity, drug-naïve status, clinical setting, positive and negative psychotic symptoms, and RoB were significant moderators of the magnitudes of FEI deficits.

CONCLUSIONS

Chinese PLwS have significant FEI impairments in terms of recognizing the six basic facial emotions, contempt, calmness, and neutral emotions, and the magnitude of impairment varies depending on the type of emotion, clinical characteristics, and the level of RoB of the study. It is necessary to consider the characteristics of FEI deficits and the clinical moderators in the FEI deficits to develop remediation strategies targeting FEI deficits in schizophrenia.

Face processing of social cognition in patients with first episode psychosis: Its deficits and association with the right subcallosal anterior cingulate cortex

The clinical importance of social cognition is well acknowledged in patients with psychosis, in particular those with first episode psychosis (FEP). Nevertheless, its brain substrates and circuitries remain elusive, lacking precise analysis between multimodal brain characteristics and behavioral sub-dimensions within social cognition. In the present study, we examined face processing of social cognition in 71 FEP patients and 77 healthy controls (HCs). We looked for a possible correlation between face processing and multimodal MRI characteristics such as resting-state functional connectivity (rsFC) and brain volume. We observed worse recognition accuracy, longer recognition response time, and longer memory response time in FEP patients when compared with HCs. Of these, memory response time was selectively correlated with specific rsFCs, which included the right subcallosal sub-region of BA24 in the ACC (scACC), only in FEP patients. The volume of this region was also correlated with memory response time in FEP patients. The scACC is functionally and structurally important in FEP-associated abnormalities of face processing measures in social cognition.

Facial affect recognition moderates the relation between autonomic nervous system reactivity and aggression during dyadic conflict

Researchers examining physiological factors of emotion have identified differential patterns of physiological reactivity among intimate partner violence perpetrators during interpersonal conflict. Although it is unclear what mechanisms are influencing these distinct physiological patterns, research suggests that perpetrators' ability to decode emotions may be involved. The current study examined how the relation between an individual's physiological reactivity and their aggression during conflict with an intimate partner is influenced by the affect they are exposed to and their affect recognition ability. Sixty-seven heterosexual couples completed self-report measures and participated in a conflict discussion while physiological measures were recorded. The sympathetic nervous system (SNS) was indexed by Skin Conductance Level (SCL) and the parasympathetic nervous system (PNS) by Respiratory Sinus Arrhythmia (RSA). Aggressive affect was coded from video. Additionally, men were administered a facial affect recognition task. Results indicated that observed aggression during the conflict discussion was associated with RSA and SCL suppression, but only for men with moderate to high affect recognition ability. Additionally, the interaction effects between physiological reactivity and affect recognition on male aggression was conditional on their partner exhibiting at least moderate levels of aggressive affect. Findings from our study suggest that the relation between autonomic nervous system reactivity during conflict and aggression toward an intimate partner is conditional on men's ability to decode the facial affect of their partner. For individuals who were able to decode aggressive affect from their partner, aggression was associated with decreased parasympathetic and SNS activation.
