A touch-scaffolded model of human prosociality

Area of Science:

• Psychology
• Neuroscience
• Developmental Biology

Background:

• Human prosociality has long been a subject of scholarly inquiry.
• Existing explanations predominantly focus on complex cognitive processes.
• The precise origins of human prosociality remain incompletely understood.

Purpose of the Study:

• To propose a novel hypothesis on the development of human prosociality.
• To investigate the role of tactile stimulation in early social development.
• To bridge the understanding between the human tactile system and prosocial behavior.

Main Methods:

• Theoretical model proposing touch-scaffolding as a foundational mechanism.
• Emphasis on the role of C-tactile afferents and neuropeptides (oxytocin, endogenous opioids).
• Focus on the caregiver-infant dyad and social schema development.

Main Results:

• Early tactile stimulation, specifically maternal touch, is hypothesized as a basic component for nascent human prosociality.
• C-tactile afferents and neuropeptides are identified as crucial mediators in the touch-prosociality link.
• This process facilitates caregiver-infant bonding and the development of positive social schemas.

Conclusions:

• Human prosociality is proposed to be touch-scaffolded, with early touch being fundamental.
• The model integrates the tactile system with psychological development of prosociality.
• This perspective offers a new framework for understanding the origins of human social behavior.
