title: da Vinci's window facilitates drawings of total and partial occlusion in young children.
abstract: When two or more objects are present in a scene, children 5 and 6 years of age rarely draw the scene such that one object totally or partially occludes another object. Instead they draw complete objects. The present study separated two components of drawing: perspective taking and graphic skill. Perspective taking was examined by comparing a free viewing condition with a restricted viewing condition in which a model could only be viewed through four apertures. Graphic skill was examined by comparing drawings requiring total occlusion with drawings requiring partial occlusion under both viewing conditions. Experiment 1 showed that 90% of 5- and 6-year-olds drew total occlusions under restricted viewing conditions but only 32% did so in the free viewing condition. Experiment 2 showed that drawings of partial occlusion were unaffected by viewing condition among 5-year-olds, but that restricted viewing increased the number of partial occlusions that 6-year-olds drew. Thus, failures of young children to draw occlusions have less to do with graphic skill than was previously thought. Instead, it is suggested that young children have a more general difficulty selecting one perspective and maintaining it over time.
