“…The emotional expression recognition task [ 9 , 13 ] was widely used to access the processing of emotional information in both healthy participants [ 40 ] and the participants with mental disorders [ 12 , 13 , 16 ], and thus, was employed in our study to explore emotion recognition ability and directly compare with the findings in adults with OSA [ 9 ]. In this task, the participants were instructed to recognize the expressions expressed by schematic faces, which has been established to be easily recognized by preschool-aged children [ 41 ] and effectively reflect the distinct brain activation pattern when comparing emotional with neutral schematic facial expressions [ 42 ].…”

“…This phenomenon is reported to be particularly pronounced for the recognition of happy (positive) and sad (negative) expressions [ 7 , 8 , 9 , 10 ]. The disappearance of this effect is considered to be suggestive of an impairment of social cognitive functioning (such as emotion recognition, emotional reactivity and emotion regulation) in certain mental disorders [ 11 ], such as schizophrenia [ 12 ], insomnia [ 13 ], learning disorder [ 14 ], attention-deficit/hyperactivity disorder (ADHD) [ 15 ] and major depressive disorder [ 16 ], which might have undesirable effects on family and peer relationships.…”

Although previous studies have reported a facial expression classification deficit among adults with SDB, we do not know whether these findings can be generalized to children. In our study, children with sleep-disordered breathing (SDB) were divided into three groups: primary snoring (n = 51), mild obstructive sleep apnea (OSA) (n = 39), and moderate/severe OSA (n = 26). All participants, including 20 healthy controls, underwent an overnight polysomnography recording and the Emotional Expression Recognition Task. Psychosocial problems were evaluated using the parent-reported Strengths and Difficulties Questionnaire (SDQ). There was a borderline significant interaction between expression category and group on reaction times. Further analysis revealed that positive classification advantage (PCA) disappeared in the moderate/severe OSA group, whereas it persisted in the control, primary snoring, and mild OSA groups. Emotional symptoms were positively correlated with OAHI. In both the happy and sad conditions, RT was negatively related to age and body mass index (BMI) but was independent of the obstructive apnea-hypopnea index (OAHI), arterial oxygen (SaO2) and total sleep time. The accuracy of identifying a sad expression was negatively related to conduct problems. Children with moderate/severe OSA exhibited dysfunction in facial expression categorization, which could potentially affect social communication ability.

“…Nonetheless, the two systematic reviews focused on the total FER only and directly pooled the effect sizes from different FER tasks together, which ignored the heterogeneity across tasks [i.e., facial emotion identification (FEI) and discrimination], so their meta-analytic findings were still not detailed enough. Since prior studies report conflicting findings on FER deficits in a specific emotion (i.e., happiness) and across a variety of FER tasks (13,(18)(19)(20), the specificity of FER deficits with respect to the category of emotion and type of FER task remains inconclusive. For example, two published studies have consistent findings on the significantly lower correct disgust and fear FEI rates in Chinese PLwS than healthy controls but have inconsistent findings on the FEI of happiness: one found comparable rates between Chinese persons with firstonset schizophrenia and healthy controls, and the other found significantly lower rates in Chinese PLwS than healthy controls (18,21).…”

BackgroundFacial 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.MethodsMajor 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.ResultsTwenty-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.ConclusionsChinese 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.
