Abstract [en]

The purpose of this study was to investigate infant’s predictive head-tracking relatively to a linearly moving object. Object’s motion was  produced by a large computer controlled plotter, tilted 15 degrees  forward from vertical position. The objects moved on a white  ainted  aluminum sheet (98x 130 cm). Objects were presented in three different conditions. It was either visible all the time, occluded during part of its motion, or the room lights were extinguished during part of the object’s motion. Infant’s head movements were recorded by two infrared cameras and mixed onto a single video screen. Each infant was shown 6 initial and 6 final visible trials, and 6 times 2 occlusion trials in between, occlusion either by occluder or extinguished light. Sticky paper was placed on the infant’s head and by a touch-screen technology the markers were coded every 100 msec.
