Visual Closure.
Groffman, Sidney
An experimental test of visual closure based on an information-theory concept of perception was devised to test the ability to discriminate visual stimuli with reduced cues. The test is to be administered in a timed individual situation in which the subject is presented with sets of incomplete drawings of simple objects that he is required to name rapidly and accurately. Interpretations of scores will reveal three categories of visual closure disability: limited closure, delayed closure, and premature closure. Results of the administration of this test to 200 children between ages 7 and 11 are reported. For younger children, the reliability of scores was too low, and for older children and adults the test did not discriminate well. Correlates between seven different perceptual tests ranged from low to very high. Ten children in each of the three visual closure disability categories were rated on behavior patterns, and the correlations were found to be particularly high for the limited closure group. Correlations between stereopsis and recovery of fusion and visual closure efficiency were also reported. References are included. (CM)
