Filmed Test to Assess Elementary School-Aged Children's Perception of Figures Which Appear to Move Away from Stationary Backgrounds
The manner in which a 30-min., 16-mm., animated black and white filmed test of field dependence was constructed is described. A sound track provides standardized test instructions. Test items are preceded on film by form-discrimination tasks and item examples to insure that form discrimination and lack of task familiarity do not affect test performance. In each of the 27 items and 5 examples a figure appears statically embedded within a background for 4 sec. In the succeeding 6 sec. of item presentation the figure continuously changes its context of embeddedness by growing larger in the visual display. This technique causes the figure to appear as if it is moving toward the viewer. Ss' performance is assessed in terms of accuracy and speed of response.
