- 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.

- What do infants know about hidden objects’? Previous research suggests that the answer depends on how the objects are hidden. For instance, infants appear to reach for toys in the dark (Clifton, Rochat, Litovsky, & Penis, 1991; Hood & Willatts, 1986) before they reach for toys occluded in the light. However, these experiments have not compared directly toys occluded in the light and by darkness. The current experiment tests infants under both conditions in the same paradigm. In addition, the experiment introduces a combined ccluderdarkness condition to test two distinct explanations for a possible advantage in the dark. First, infants may have knowledge about hidden objects but cannot act on it for occluder-specific reasons (e.g., means-ends deficits, beliefs about the whether the object is accessible). Second, infants may have graded representations of occluded objects that can be more easily maintained in the face of global darkness than with the direct visual interference of an occluder. Counterintuitive results from the current experiment provide evidence for both representational and occluder-specific effects.

- There has been a discussion in the literature about the processes involved in infant behavior regulation. In this study, social referencing and mood modification were contrasted by looking for specificity in infant behavior regulation following different
