Correlates of performance on the Gollin and Mooney tests of visual closure

One hundred and twenty-seven undergraduate students variously performed a computerized version of the Gollin (1960) Incomplete Figures Test, the Mooney (1957) Test of Incomplete Face Perception, the Poppelreuter (1917) Overlapping Figures Test, and a visual search task. Performance of male subjects was superior to that of female subjects on the Mooney test but inferior on the visual search task. Correlation and regression analyses showed that the only significant predictor of Gollin test scores was latency to identify all items in the Overlapping Figures Test. There was no relationship between performances on the Gollin and Mooney tests or between Gollin or Mooney test performance and visual search latency. The Gollin and Mooney tests appear to access different perceptual processes, none of which is dependent on the efficiency of visual search.
