Summary: This study explored the relationship between self-criticism and pupillary reactivity, finding that pupillary reactivity can predict levels of self-criticism and identify pathological levels. The results showed that pupillary reactivity can be a promising biomarker for diagnosing self-criticism and self-reassurance levels based on reactions to different facial expressions, especially towards Disgust.

Summary: Human social interaction integrates various communication channels, such as speech, facial expressions, body gestures, and touch. Recognizing human emotions through these channels is crucial for natural human-robot interaction. However, there is limited research on touch-based multimodal emotion recognition (MER). This work introduces a dataset (FETE) that combines facial expression and touch gesture for emotion recognition. Additionally, a multi-eigenspace based multimodal fusion network (MMFN) is proposed for tactile-visual bimodal emotion recognition. The experiments on the FETE dataset show that MMFN achieves significant improvement in accuracy compared to single-modality approaches.

Summary: This study examined the association between interpersonal difficulties and emotion decoding ability in healthy individuals. The results showed negative correlations between interpersonal agency and recognition of facial anger and disgust, indicating that poor recognition of these emotions might contribute to interpersonal problems with social dominance. However, there was no correlation between interpersonal communion and emotion recognition ability.

Summary: This study examined the effect of temporal parameters on the perceived intensity of facial expression in each emotion, and how the effect varies with autistic traits in typically developing people. The results showed that the intensity of facial emotion was perceived more strongly when the presentation ratio increased and when the emotional expression was presented last. The effects were different among the emotions and the perceived intensity of angry expressions decreased with autistic traits.

Summary: The study found that pupil dilation in a female virtual partner led to a significant increase in the observers' right pupillary diameter, while pupil constriction induced a significant increase in the participants' parasympathetic nervous system HRV response. This suggests that female virtual interaction partners have the ability to modulate parasympathetic autonomic functioning in young healthy male humans.

Summary: The human brain is able to predict and attenuate the sensory outcomes of one's own actions through efference copies, although the sensory percepts of self-touch are not fully cancelled out. Self-touch has behavioral relevance, helping individuals to refocus attention, calm down, relieve stress, and enjoy themselves.

Summary: The pleasantness of gentle stroking varies greatly between individuals and studies, indicating that there may be other relevant factors to consider. The affective value of a touch event is determined by how well its perceived purpose matches the goals of the touch receiver, which is influenced by sensory characteristics, setting, person factors, and the touchee's expectations.

Summary: This study aimed to examine whether childhood adversity increases opioid reward during surgery. The results showed that childhood adversity did not have a significant effect on drug-induced feelings of pleasure, but it was negatively associated with drug liking. Exploratory analysis suggested a potential nonlinear relationship between childhood adversity and positive opioid effects. Future research should investigate the link between childhood adversity, subjective effects, and opioid use after surgery.

Summary: Exposure to opioid analgesics during surgery increases the risk of new persistent opioid use. The belief that acute opioid treatment improves well-being and relieves anxiety is not consistently supported by laboratory studies of non-opioid users. This observational study found that opioid-induced improvement of well-being is infrequent in opioid-naive patients.

Summary: This study conducted in a Norwegian hospital observed 270 outpatient surgery patients and found that only 35% of them took pain relief medication at home 1-2 days after discharge. The use of pain relief medication was associated with factors such as chronic pain, pre- and post-surgical pain severity, and the ability to cope with pain. However, the low levels of postoperative pain did not lead to widespread chronic opioid use.

Summary: This study compared the brain activity of participants with anorexia nervosa, autism spectrum condition, and a comparison group without diagnoses during a self-other-touch task. The results showed that participants with anorexia nervosa had increased neural activity in response to both self-touch and social touch, while participants with autism spectrum condition were mostly comparable to the comparison group. This suggests that there may be differences in body perception and self-other-distinction between anorexia nervosa and autism spectrum condition.

Summary: This study investigates how subtle differences in skin-to-skin contact affect the recognition and rating of emotional messages. The results show that touchers vary contact attributes to convey distinct messages, which can be recognized by receivers. These nuances in touch are also correlated with receivers' emotional arousal and valence.

Summary: The mechanisms through which intranasal oxytocin affects the brain are not fully understood, but recent research suggests that brain regions with a higher density of oxytocin receptors may play a key role. This study used resting-state fMRI to investigate the effects of intranasal oxytocin administration on connectivity between these receptor-enriched regions and other regions in the brain, and found that the effects varied depending on the age of the participants.

Summary: Depression and cardiovascular disease are influenced by daily life stress, but the biological mechanisms behind this connection are not well understood. This study shows that the ventromedial prefrontal cortex (vmPFC) plays a role in regulating stress responses and behavior, with sex-specific effects. In males, the vmPFC-PH circuitry promotes positive motivation and reduces stress responses, while in females it elevates stress responses. This suggests that cortical regulation of stress reactivity and behavior is mediated by projections to the hypothalamus in a sex-specific manner.

Summary: The COVID-19 pandemic has led to increased life stress and internalizing disorders, with a disproportionate impact on women. This study focused on the neuroendocrinology of stress-related disorders and found that women have lower cortisol responses and higher DHEA responses to stress. However, lower cortisol and higher DHEA are associated with internalizing disorders in women, while the opposite is true in men. The study also examined the relationship between COVID-related stress and internalizing symptoms and found gender differences in the association between DHEA and cortisol and internalizing outcomes. These findings suggest distinct neuroendocrine pathways for stress-related disorders in young men and women.
