When an object moves behind an occluder and re-emerges, 4-month-old infants perceive trajectory continuity only when the occluder is narrow, raising the question of whether time or distance out of sight is the important constraining variable. One hundred and forty 4-month-olds were tested in five experiments aimed to disambiguate time and distance…

Three experiments investigated 2- to 6-month-olds' perception of the continuity of an object trajectory that was briefly occluded. Results across experiments provided little evidence of veridical responses to trajectory occlusion in the youngest infants, but by 6 months, perception completion was more robust. Results suggest that perceptual…
