Key result
Males exhibited significantly higher oxyhemoglobin concentrations in Broca's area, motor area, sensorimotor cortex, and temporal lobe areas compared to females during interactive drawing tasks.
Why the study?
Interpersonal interaction is essential to romantic couples, and understanding how gender impacts brain activities during intimate interaction is crucial.
Do males and females exhibit different oxyhemoglobin changes during interactive drawing tasks in romantic couples?

p-value: p=<0.05
Males show heightened goal-oriented neural engagement during interactive drawing tasks compared to females, with temporal area activation correlating with relationship quality.
Hypothesis-generating for gender-specific neural responses in couple interactions; leaves open clinical relevance pending larger prospective studies.
Interpersonal interaction is essential to romantic couples. Understanding how gender impacts an individual's brain activities during intimate interaction is crucial. The present study examined gender differences in oxyhemoglobin (oxy-Hb) changes during real-time drawing interactions between members of romantic couples using non-invasive functional near-infrared spectroscopy (fNIRS). We analyzed the oxy-Hb concentrations of romantic couples engaged in interactive (i.e., chase and escape) and non-interactive (i.e., individual) drawing sessions. Our findings indicated that males (vs. females) exhibited more pronounced oxy-Hb concentrations in Broca's area, motor area, sensorimotor cortex, and temporal lobe areas than women in an interactive drawing task, suggesting a heightened goal-oriented engagement in social interaction. Significant positive correlations were found between oxy-Hb volumes of the temporal area and the Quality of Relationship Index (QRI), underscoring the impact of interpersonal dynamics on brain function during interactive tasks. This study deepens the understanding of gender differences in neural mechanisms in social interaction tasks and provides important insights for intimacy research.

Huang et al. (2025) conducted an observational in Healthy romantic couples (n=68). Male gender vs. Female gender was evaluated on Oxyhemoglobin (oxy-Hb) concentration changes in regions of interest during interactive drawing tasks (p=<0.05). Males exhibited significantly higher oxyhemoglobin concentrations in Broca's area, motor area, sensorimotor cortex, and temporal lobe areas compared to females during interactive drawing tasks.
