In the typically developing population, social touch experiences are influenced by several factors, including the biological sex of toucher and receiver, the body area wherein the touch is delivered and the social context in which the tactile exchange occurs. However, it is currently unexplored how social touch experiences of autistic adults are…

Introduction: The objective of the current study was to design and pilot-test a nonverbal intelligence test for children and adolescents with visual impairment (i.e., blindness and low vision) aged 10 to 16 years. Method: A three-dimensional haptic matrix test of nonverbal cognitive abilities (3-DHMT-CA), initially developed for adults with visual…

Studies conducted in Western countries document the special role of mother--infant face-to-face exchanges for early emotional development including social smiling. A few cross-cultural studies have shown that the Western pattern of face-to-face communication is absent in traditional rural cultures, without identifying other processes that promote…

It is still unclear how the visual system perceives accurately the size of objects at different distances. One suggestion, dating back to Berkeley's famous essay, is that vision is calibrated by touch. If so, we may expect different mechanisms involved for near, reachable distances and far, unreachable distances. To study how the haptic system…

In this article, the authors investigated unimodal and cross-modal processes in spatial working memory. A number of locations had to be memorized within visual or haptic matrices according to different experimental conditions known to be critical in accounting for the effects of perception on imagery. Results reveal that some characteristics of…
