This paper presents some results of research carried out with a group of blind and partially sighted youths who are enrolled in a school for people with visual disabilities in Brazil. This research aims to promote different articulations between the body and cognition. Based on actor–network theory, it considers that having a body means learning to be affected by widely differing actors. The field research was carried out through body expression activities, which seek to promote connections between the body and heterogeneous materials, such as a ball, a rattle or a colleague. The paper indicates that cognition is the effect of these collective body experiences. It also underlines that these body experiences have produced new ways of knowing amongst the blind and partially sighted youths. In the conclusion it is stressed that psychology research on disability must be done with (and not about) people with visual disability.
