Summary: This study examined the relationship between cognitive insight and clinical insight in patients with schizophrenia, finding that metacognition mediated this relationship and positive symptoms also played a significant mediating role. The results suggest that deficits in reflective thinking abilities may impact the formation of complex and integrated self-ideas in schizophrenia.

Summary: This study investigated the contribution of decision-making, cognitive insight, and theory of mind to insight in schizophrenia spectrum disorders. The findings showed that cognitive insight and decision-making were the main cognitive processes underlying insight. Metacognitive interventions may improve insight in these disorders, but may not address treatment compliance.

Summary: Multiple cognitive biases, including liberal acceptance (LA) bias, have been suggested to contribute to reality distortion in psychotic disorders. This study examined a similar bias called acceptance of the implausible (AOI), and found that first-episode psychosis (FEP) patients expressed more AOI than control subjects, and the magnitude of AOI correlated with the severity of delusions and theory of mind (ToM) performance. One year later, even when most patients were in remission, patients still displayed increased AOI, which was no longer correlated with delusions. These findings suggest that AOI bias could be a trait feature and may be a causal factor of psychotic disorders, possibly associated with ToM.

Summary: This study examines the EEG local synchrony of mind wandering associated with schizophrenia, finding significantly lower power in mind wandering states compared to task-focused states in schizophrenia patients, mainly in the frontal and posterior regions. The differences between task-focused and mind wandering states in healthy controls are primarily in the posterior region. Additionally, power in frequency bands during mind wandering and task-focused attention correlates with cognitive variables such as processing speed and working memory.

Summary: This study aimed to examine the association between Theory of Mind (ToM) deficits and clinical symptoms of schizophrenia using a recent assessment method. The results showed significant correlations between ToM and the positive and cognitive/disorganization dimensions of schizophrenia when controlling for non-social cognitive abilities. The negative symptoms dimension was only significantly correlated with ToM when non-social cognitive abilities were not controlled for.

Summary: This study validated the False Belief task as a measure of Theory of Mind in schizophrenia and found that individuals with schizophrenia exhibited reduced brain activation in the bilateral TPJ during the task, which was positively associated with ToM abilities. Lower neural activity in the bilateral TPJ was associated with ToM impairments observed in individuals with early course schizophrenia.

Summary: In this study, a systematic literature search was conducted to identify studies using neuroimaging to measure theory of mind (ToM) in schizophrenia. The results showed that patients with schizophrenia exhibited hyperactivations in the superior longitudinal fasciculus II and hypoactivations in the superior frontal gyrus, precuneus and cuneus, and precentral gyrus during ToM tasks. The primary brain regions involved in the potential neuropathways in schizophrenia were the middle temporal gyrus, superior and inferior frontal gyrus, and supplementary motor areas.

Summary: Patients with psychosis showed more pronounced deficits in Cognitive and Affective ToM compared to non-clinical controls, while there were no significant differences in Hyper-ToM errors. Deficits in Cognitive ToM were associated with general delusions, while problems in Affective ToM were linked to negative and disorganized symptoms. Furthermore, there was no association between Hyper-ToM errors and any symptoms when controlling for educational level.

Summary: The anterior insula (AI) plays a central role in coordinating attention and integrating information from multiple sensory modalities. This study used fMRI scanning and a task experiment to investigate the role of the AI in audiovisual speech synchrony judgment (SJ). The findings suggest that AI is involved in asynchrony detection and may generate a control signal to support conflict-resolving and response selection. However, the study did not find significant variation in audiovisual synchrony perception and AI activation and connectivity related to autistic traits.

Summary: Emotion-behaviour decoupling, experiential pleasure deficits, and emotion expressivity deficits can all influence the clinical and functional outcome of schizophrenia. A study with 127 first-episode schizophrenia patients found that these three constructs can differentiate subgroups, and emotion-behaviour decoupling and experiential pleasure deficits are associated with more severe negative symptoms and poorer social functioning.

Summary: The Caregiver Strain Questionnaire assesses caregiver strain on three dimensions: objective, subjective externalized, and subjective internalized strain. It has been validated among caregivers of children with Autism Spectrum Disorder (ASD) in the United States and Mainland China, showing promising psychometric properties. This study aimed to develop and validate the Chinese (traditional script) version of the questionnaire (C-CGSQ) among 198 caregivers of ASD children in Hong Kong. The C-CGSQ demonstrated excellent internal consistency (α = 0.958), test-retest reliability (Spearman's r = 0.966), and established concurrent, convergent, divergent validity, and a three-factor structure consistent with previous studies.

Summary: Previous studies on cognitive heterogeneity in psychotic disorders have mainly focused on chronic schizophrenia, with limited data on first-episode psychosis (FEP). This study identified three cognitive subgroups in adult FEP patients using a data-driven cluster analytic approach and examined their relationships with illness-related variables. The results showed significant differences in demographic and illness-related variables among the three subgroups, highlighting the importance of further research on the longitudinal relationships between cognitive subgroups and clinical and functional outcomes in FEP.

Summary: This study investigated the effects of non-pharmacological intervention on executive functions (EFs) in children and adolescents with attention-deficit/hyperactivity disorder (ADHD). A total of 67 studies were included, and interventions were categorized into six types: cognitive training, EF-specific curriculum, game-based training, mindfulness practice, neurofeedback training, and physical exercise. Overall, non-pharmacological interventions had significant moderate to large effects on overall EFs in ADHD children and adolescents, with physical exercise showing a particularly positive effect on specific EF domains such as inhibitory control and cognitive flexibility.

Summary: Interoception, the physiological awareness of our body, is impaired in individuals with autism spectrum disorders. Subclinical autistic traits, which are mild manifestations of autistic symptoms, are present in the general population. In a study of 62 healthy young adults, it was found that autistic traits were negatively correlated with the resting-state functional connectivity (rsFC) between certain brain regions, while interoceptive accuracy and sensibility were positively correlated with rsFC between interoceptive brain networks and other regions. These findings suggest a negative relationship between interoception and autistic traits, which can be explained by self-report measures and decreased rsFC within the interoceptive brain network.

Summary: This study surveyed 94 teachers in Australia who work in preschool or the early years of primary school to understand their perspectives on using social robots in the classroom. The teachers identified benefits such as improved learning and engagement for young children, as well as barriers like cost, limited training, and technical support. Overall, the teachers had a neutral view towards social robots. It is recommended that early childhood teachers receive more opportunities and training to experience and utilize these new digital technologies for supporting children's learning in the classroom.
