Publication Type: Individual Poster Abstract: Previous experiments using a 2D display have evidenced that 4 month-old infants can process the perspective cues when they are combined with dynamic interposition in an object permanence situation and that 5 month-old infants seem to be able to perceive depth when only perspective cues are presented. This capacity is not demonstrated in 4 month-old infants (Durand, Lécuyer 2002; Durand, Lécuyer, Frichtel 2003). Two experiments were conducted to test 4-month-old infants’ ability to process the cues offered by perspective and texture gradient. A dynamic 2D display of a 3D scene was shown to infants, in which a car seemed to move in a scenery providing perspective and texture gradient cues. The apparent distance of the car was related to its size. The looks were recorded with an eye-tracking-system. Analyses have been carried out with looks on the complete display and around the car. The first experiment comprised a habituation event and two test events. During the habituation phase, the car was moving back and forth on one side of an alley, being small when “far” and large when “near”. In the normal test phase, the car was simply moving along the other side of the alley. In the strange test phase, the car was large when “far” and small when “near”. Infants looked more on the whole screen and around the car for the strange event than for the normal event. The difference between the looks in the habituation event and the test events was not significant on the complete display but infants looked more around the car for the habituation event than for the “normal” event. In the second experiment, there was no habituation event. No significant difference was observed between the looks for the “normal” and the “strange” events on the complete display as at the car and 4° around. When confronted to the previous results obtained with a less rich environment (with no texture gradients), these results indicate that this last cue plays an important role for depth perception in infants, but that the use of this type of cue is still delicate in 4-month-olds.
