Abstract
Surprisingly little scientific research has been conducted on the topic of interpersonal
touch over the years, despite the importance of touch in our everyday social interactions
from birth through to adulthood and old age. In this review, we critically evaluate
the results of the research on this topic that have emerged from disciplines, such
as cognitive and social psychology, neuroscience, and cultural anthropology. We highlight
some of the most important advances to have been made in our understanding of this
topic: For example, research has shown that interpersonal tactile stimulation provides
an effective means of influencing people's social behaviors (such as modulating their
tendency to comply with requests, in affecting people's attitudes toward specific
services, in creating bonds between couples or groups, and in strengthening romantic
relationships), regardless of whether or not the tactile contact itself can be remembered
explicitly. What is more, interpersonal touch can be used to communicate emotion in
a manner similar to that demonstrated previously in vision and audition. The recent
growth of studies investigating the potential introduction of tactile sensations to
long-distance communication technologies (by means of mediated or 'virtual' touch)
are also reviewed briefly. Finally, we highlight the synergistic effort that will
be needed by researchers in different disciplines if we are to develop a more complete
understanding of interpersonal touch in the years to come.
