Two-Year-Olds' Object Retrieval Based on Television: Testing a Perceptual Account

Two-year-olds frequently fail to use information provided by video to find objects hidden in an adjacent room. Schmitt and Anderson (2002) hypothesized that they fail to map the 2-dimensional (2D) video image onto the 3D layout of the search space. Two experiments tested whether 2-year-olds can successfully use information from video when the search space is 2D or when the information is provided verbally (by telling the child where the toy is hidden). In both experiments, children performed poorly in the video conditions but performed well in direct live experience comparison conditions, contradicting Schmitt and Anderson's hypothesis. Performance was above chance on the first trial in the video conditions, suggesting that 2-year-olds do have a memory of the hiding location, albeit one that is easily disrupted by perseverative errors on subsequent trials. Overall, the results are most consistent with the hypothesis that very young children give priority to direct experience over mediated information.
