A fundamental characteristic of social exchanges is the synchronization individuals' behaviors, physiological responses, and neural activity. However, association between how individuals communicate in terms emotional content expressed associative knowledge interpersonal synchrony has been scarcely investigated so far. This study addresses this research gap by bridging recent advances cognitive neuroscience data, affective computing, data science frameworks. Using functional near-infrared spectroscopy (fNIRS) hyperscanning, prefrontal were collected during interactions involving 84 participants (i.e., 42 dyads) aged 18-35 years. Wavelet transform coherence was used to assess participants. We manual transcription dialogues automated methods codify transcriptions as levels syntactic/semantic networks. Our quantitative findings reveal higher than random expectations superior frontal gyrus (q = .038) bilateral middle gyri (q< .001, q< .001). Linear mixed models based on dialogues' only significantly predicted across cortex (Rmarginal2=3.62%). Conversely, relying features more effective at local level, for predicting brain right (Rmarginal2=9.97%). Generally, not when limited from one region interest a time, whereas show opposite trend, losing predictive power incorporating all regions interest. Moreover, we found an interplay emotions synchrony, providing support major role played these linguistic components processes. identifies mind-brain duality reflecting levels, opening new ways investigating human interactions.

Securely Stressed: Association between Attachment and Empathic Stress in Romantic Couples

Stress-related disorders are common in modern societies. What adds to the burden is empathic stress, arising when observing another’s stress elicits a response observer. In romantic couples, we investigated association between and adult attachment – deep emotional bond partners understand its inherent facets of risk resilience. Psychosocial was induced one partner (“target”) while other passively observed situation (“observer”). Stress reactivity measured both via salivary cortisol, heart rate, high-frequency rate variability, questionnaires. Observers’ representations were assessed using Adult Attachment Interview. We found higher cortisol resonance that is, proportionality targets observers dyads with securely as opposed insecurely attached (specifically insecure-dismissing) observers. Consistent resilience factor, our results suggest individuals physiologically more tune their during psychosocially stressful situations, possibly allowing for mutual understanding triggering supportive behavior. However, suggesting potential security, contexts frequent or extreme may also be prone excessive activation subsequent health impairments.

Le cerveau parental : structure, fonction et synchronisation intercérébrale parent-enfant

La transition vers la parentalité est marquée par une plasticité importante du cerveau adulte, qui a des effets durables sur neurobiologie et le comportement parent de l’enfant en développement. L’article donne un aperçu : 1. façon dont structure fonction changent lors parentalité, 2. ce que nous savons synchronisation intercérébrale entre l’enfant. Le parental organe dynamique rappelle les parents ne naissent pas, mais qu’ils se fabriquent.
