Cardiac Synchrony During Collaborative Drawing: A Longitudinal Comparison of Same Generation and Intergenerational...

Area of Science:

• Social Gerontology
• Psychophysiology
• Human Development

Background:

• Intergenerational social programs offer relationship-building opportunities.
• Existing research highlights health and wellbeing benefits of these programs.
• The physiological underpinnings of intergenerational interactions remain largely unexplored.

Purpose of the Study:

• To investigate the physiological consequences of repeated intergenerational encounters.
• To understand how social programs shape dyadic physiological responses and relationship formation.
• To examine cardiac synchrony as a measure of intergenerational connection.

Main Methods:

• Tracked cardiac synchrony in intergenerational and same-generation dyads over a six-session drawing program.
• Recorded physiological signals (neural, cardiac) and motion capture data during collaborative and individual drawing tasks.
• Utilized self-report measures for social closeness and analyzed interpersonal distance.

Main Results:

• Collaborative behavior, social closeness, and interpersonal distance exhibited group-specific patterns.
• Interpersonal distance emerged as a reliable objective measure of relationship development.
• Cardiac synchrony did not consistently correlate with behavioral or self-report measures, but showed a trend for increased arousal in intergenerational dyads during collaboration.

Conclusions:

• Behavioral and self-report measures more effectively characterized relationship development than cardiac synchrony in this study.
• Cardiac synchrony may indicate marginally enhanced arousal during active collaboration between older and younger adults.
• Further research is needed to fully elucidate the physiological mechanisms underlying intergenerational relationship formation.
