Abstract A tendency to procrastinate has previously been linked low attentional control and poor emotion regulation skills. Building upon these findings, in the present study we investigated whether relationship between procrastination attention can be corroborated explained by dysregulation dispositional spontaneous mind‐wandering. University students completed questionnaires along with Attentional Networks Test for Interactions Vigilance – executive arousal components. The results showed that trait is inversely related some indices of vigilance. Interestingly, direct effects vigilance scores disappeared when or mind‐wandering were included model. Obtained findings suggest difficulties managing emotional reactions over focus one's thoughts might explain increased chronic procrastination.

Abstract The prevalence of physically inactive lifestyles in modern society raises concerns about the potential association with poor brain health, particularly lateral prefrontal cortex, which is crucial for human prosocial behavior. Here, we explored relationship between physical activity and behavior, focusing on neural markers, including intra-brain functional connectivity inter-brain synchrony cortex. Forty participants, each paired a stranger, completed two experimental conditions randomized order: (i) face-to-face (ii) face stimulus (eye-to-eye contact fictitious person displayed screen). Following condition, participants played economic games either their partner or an assumed screen. Neural cortex was recorded by near-infrared spectroscopy hyperscanning. Sparse multiset canonical correlation analysis showed that lifestyle covaried poorer reciprocity, greater trust, shorter decision-making time, weaker dorsal ventral These associations were observed exclusively condition. Our findings suggest may alter behavior impairing adaptable response to social factors through altered synchrony.
