a perceptual test in which each item consists of one simple geometrical figure and four complex figures: The participant is asked to identify which one of the complex figures has the simple figure embedded within it. The test, which was developed from the earlier Gottschaldt Figures Test, is considered to be an index of perceptual flexibility. Also called Concealed Figures Test. [originally developed by German psychologist Kurt Gottschaldt (1902–1991)]
