University of TorontoThis experiment investigated the role of active versus passive body movement information and visual information on spatial orientation. Infants aged 13 to 15 months completed a search task that required them to retrieve a toy from one of two containers. Before search, the infants or the hidden objects were rotated 180°, or no movement occurred. These displacements allowed for a manipulation of body movement information and, on the infant displacement trials, infants were either rolled around on a chair (passive self-movement) or walked around the table (active self-movement). Visual information was manipulated by having these displacements occur in a fight or dark environment. Search was best following no movement and overall accuracy was significantly better in this condition than after object movement; no other differences between movement conditions were evident. The results do not indicate any facilitation of active movement on search, and are discussed with respect to previous findings.M.A
