Noncanonical orientation without occlusion: Children's drawings of transparent objects

Abstract

The use of a transparent model in a drawing task allows all the features of the model to remain visible whatever its orientation. N. H. Freeman (1980, Strategies of Representation in Young Children, New York/London, Academic Press) found that when drawing a transparent glass with its handle turned away, children made more canonical errors (drawing the handle at the side) than when drawing a similarly orientated opaque cup. According to Freeman being able to see the handle in a noncanonical orientation “triggers” a canonical representation of the object ( N. H. Freeman 1980, p. 252). Two experiments are reported which investigated children's drawings of transparent objects. The drawings obtained from children between 4 and 7 years old produced two major findings. First, the tendency toward canonicality when drawing a glass with its handle turned away was significantly reduced when two glasses in differeing orientations were presented side by side. Second, the number of canonical errors was lower when the glass was filled with milk (thus hiding the handle). This latter finding confirms that of N. H. Freeman (1980). However, the first suggests that children use situationally appropriate information when drawing transparent objects in a way similar to that noted by A. M. Davis (1983, Contextual Sensitivity in Young Children's Drawings, Journal of Experimental Child Psychology, 35, 478–486) using opaque objects.
