The social softness illusion makes others' skin feel softer than our own, enhancing social bonding. This effect strengthens when self-other body distinction is clearer, like in an allocentric perspective.
Area of Science:
- Social Psychology
- Neuroscience
- Haptics
Background:
- The social softness illusion, where others' skin feels softer than one's own, is linked to social-emotional sharing via affective touch.
- Understanding the factors modulating this illusion is crucial for its role in social bonding.
Purpose of the Study:
- To investigate if the ability to distinguish another's body from one's own body influences the social softness illusion.
- To examine the impact of spatial perspective and visual feedback on this illusion.
Main Methods:
- Female participants acted as touch givers or receivers.
- Touch location (palm/forearm), spatial perspective (egocentric/allocentric), and visual feedback were manipulated.
- Perceived skin softness was compared between self and other.
Main Results:
- The social softness illusion was confirmed, with others' skin perceived as softer than one's own.
- The illusion persisted across different touch locations (palm, forearm).
- The illusion was significantly stronger in the allocentric perspective compared to the egocentric perspective.
Conclusions:
- The capacity to differentiate one's body from another's modulates the social softness illusion.
- Clearer self-other body distinction enhances the illusion, supporting its role in fostering social relationships.
- Findings highlight the interplay between body representation and social touch perception.
