An Update on Social Touch

Abstract. Recent research suggests that early physical touch provided by caregivers may play a critical role in cognitive and affective development. The discovery of the C-tactile fibers – which selectively respond to low-speed physical stimulations, such as maternal affectionate touch and caresses – opened a promising field of research into the physiological bases of human togetherness. Notably, C-tactile fiber stimulation is primarily elaborated in a specific brain area (i.e., the insula), which is involved in affective and socio-cognitive skills as well as in the development of an individual’s body image. In the present study, we provide a narrative overview of the research conducted so far on the role of maternal affectionate touch in infants’ cognitive and emotional development, and we highlight potential implications for clinical practice with children and adults.
