Summary: The research focuses on affective architecture issues related to the generation of expressive facial behavior and critiques approaches that view expressive behavior solely as a reflection of internal states rather than social signals. The study discusses the benefits of combining these two approaches and analyzes the requirements for generating expressive behavior as social signals at reactive and cognitive levels. Proposed generic architectural mechanisms are based on an explicit mind-body loop and Theory of Mind processing, with a illustrative scenario provided for demonstration.

Summary: The purpose of this study was to explore the abnormalities in cognitive manipulation in patients with depression and analyze its possible role in the pathogenesis and maintenance of depression. The results showed that patients with depression had obvious difficulties in cognitive manipulation, especially when dealing with sad stimuli. Furthermore, the difficulty in cognitive operation was closely related to the level of rumination.

Summary: Ostracism induces physiological, behavioral, and cognitive changes in adults and affects children's cognitive abilities. This study investigated the impact of social inclusion and ostracism on emotion recognition abilities in 5- and 10-year-old children. Results showed that previously ostracized children had lower misidentification rates compared to included children. The social manipulation affected 5-year-olds' decoding abilities, while no difference was observed in 10-year-olds. Additionally, 10-year-olds and ostracized 5-year-olds showed higher accuracy and sensitivity for fearful expressions. Overall, this study provides evidence of how Cyberball-induced inclusion and ostracism modulate children's recognition of emotional faces.

Summary: The current longitudinal study examined maternal facial emotion recognition and infant affect-based attention using eye-tracking at different ages. The results showed consistent maternal responses to angry facial expressions, indicating a trait-like response to social threat among mothers. However, neither maternal responses to happy or fearful facial expressions nor infants' responses to all three facial emotions showed such consistency, suggesting the changeable nature of facial emotion processing, especially in infants. The study also found dynamic changes in infants' attention to negative emotions and limited evidence for developmental continuity in processing negative emotions and the bidirectional interplay of infant affect-biased attention and maternal facial emotion recognition.

Summary: This study explores the use of neurofeedback training and positive autobiographical memory retrieval in modulating neural networks involved in emotion regulation and memory recall in adolescents with depression. The results suggest that neurofeedback training can increase activity in the amygdala, hippocampus, and anterior cingulate cortex, and further investigation is needed to determine the optimal dosage of the training for depressed youth.

Summary: This study developed an android head called Nikola and conducted three studies to validate its facial expressions. The results showed that Nikola can appropriately produce facial actions and its prototypical facial expressions for basic emotions can be accurately recognized by naive participants. The speed of Nikola's dynamic facial expressions also affects emotion expression, similar to previous studies of human expressions. These findings validate the effectiveness of Nikola's emotional facial expressions and suggest its potential for future psychological studies and real-life applications.

Summary: This study examined attentional biases towards different emotional expressions and found no consistent links between these biases and social anxiety or autistic traits. Only an exploratory Bayesian analysis suggested a weaker bias towards happy facial expressions in individuals with higher autistic trait levels. Furthermore, the attentional bias towards angry facial expressions appeared to be influenced by an interplay between both trait dimensions. Novel approaches in assessing attentional biases may provide a more valid description of disorder-specific biases in attention to emotions.

Summary: The normative, developmental changes in affect-biased attention during the preschool years are largely unknown. This study explored attention bias for emotional versus neutral faces in children aged 2.5 and 5 years. The results showed age-specific and specific attention biases for different emotional expressions, with sustained attention for fearful faces being the strongest. There is a need for future studies to focus on small age ranges and cover multiple subcomponents of attention during the preschool years.

Summary: In this study, a consortium called "COORDINATE-MDD" was established to define patterns of brain alteration in major depressive disorder (MDD) using neuroanatomical and neurofunctional heterogeneity as dimensions. By harmonizing imaging data and using machine learning methods, the project aims to predict treatment response at the individual level. International datasets from various MDD populations are being shared, and novel predictors of treatment response are being identified and validated externally.

Summary: Evidence from a population genetic database showed that variation in the CLDN5 gene can modulate the effects of the IL6 gene variant in stress-induced depression in humans. The interaction among interleukin-6, claudin-5, and recent stress may be involved in the development of depression. These genetic polymorphisms may help to identify individuals at higher risk for stress-induced depression.

Summary: This study suggests that elevated glutamate levels in the anterior cingulate cortex (ACC) are associated with poor response to antipsychotic treatment in schizophrenia. However, glutamate metabolites in the caudate are not predictive of treatment response. These findings highlight the potential utility of glutamate as a biomarker for predicting treatment response in early psychosis.

Summary: A recent umbrella review found no consistent evidence linking serotonin to the pathophysiology of depression. However, we argue that this conclusion is overstated due to methodological weaknesses, selective reporting of data, oversimplification, and errors in the interpretation of neuropsychopharmacological findings. We use the examples of tryptophan depletion and serotonergic molecular imaging, the two most relevant research areas, to support our argument.

Summary: The period of adolescence is characterized by the interplay between social context, brain development, and emotional symptoms. This study aimed to investigate the associations between peer problems, family support, socioeconomic stress, emotional symptoms, amygdala volume, and vmPFC GMV in both sexes. The findings revealed that peer problems and emotional symptoms changed together over time, and there was a positive correlation between vmPFC GMV, peer problems, and emotional symptoms in males. Additionally, greater family support was associated with slower growth of amygdala volume in males. These findings contribute to our understanding of the complex relationship between social, emotional, and brain development and offer potential avenues for promoting mental health.

Summary: Manipulation of tryptophan intake can rapidly induce and alleviate depression symptoms. This study investigates the effect of habitual tryptophan intake on mood symptoms and the influence of genetic factors. High dietary tryptophan ratio provides a protective effect against depression. Genetic associations with depression are found in the low tryptophan ratio group, particularly in serotonin and kynurenine pathways. Understanding the interaction between genetics and diet can lead to personalized prevention and intervention for mood disorders.

Summary: This study found differences in behavioral and brain responses to social feedback between individuals with subthreshold depression and healthy controls. Individuals with subthreshold depression had lower expectations for positive feedback and showed reduced activation in the medial prefrontal cortex when expecting positive feedback. They also exhibited increased dorsal anterior cingulate cortex activity after receipt of unexpected social rejection and reduced ventral striatum activity after receipt of unexpected social acceptance.
