| Abstract | In recent years, the old debate about the beginning of representational capacities in childhood has been revived, fueled by new evidence of early cognitive capacities. This new evidence necessitates further reflection on the nature of the representations involved in early cognitive functioning. One important goal is to determine which situation will provide a better understanding of these representations. We hypothesize that the use of depth cues, especially perspective cues, in a two-dimensional (2-D) display is one of these situations, because the perceiver needs to build a representation from incomplete information. Three experiments were carried out to test the capacity of young infants to use perspective cues to build a three-dimensional (3-D) representation in a 2-D display. In the test phase of the first experiment, infants did not evidence a capacity to extrapolate to apparently further objects a size/apparent distance relation presented to them in the habituation phase. However, in the second experiment, infants dishabituated with apparently nearer objects when this rule was violated. In the third experiment, infants also dishabituated to a situation where an object was apparently growing in size when moving away and decreasing when coming nearer. These results seem to indicate that this representational capacity emerges between |
