Our sense of touch can contribute to our ability to perceive faces, according to new research published in Psychological Science, a journal of the Association for Psychological Science.

“In daily life, we usually recognize faces through sight and almost never explore them through touch,” says lead researcher Kazumichi Matsumiya of Tohoku University in Japan. “But we use information from multiple sensory modalities in order to perceive many everyday non-face objects and events, such as  or  – these new findings suggest that even face processing is essentially multisensory.”

In a series of studies, Matsumiya took advantage of a phenomenon called the “face aftereffect” to investigate whether our visual system responds to nonvisual signals for processing faces. In the face aftereffect, we adapt to a face with a particular expression – happiness, for example – which causes us to perceive a subsequent neutral face as having the opposite facial expression (i.e., sadness).
Matsumiya hypothesized that if the visual system really does respond to signals from another modality, then we should see evidence for face aftereffects from one modality to the other. So, adaptation to a face that is explored by touch….
