Sally–Anne test

The Sally–Anne test is a psychological test originally conceived by Daniel Dennett, used in developmental psychology to measure a person's social cognitive ability to attribute false beliefs to others. Based on the earlier ground-breaking study by Wimmer and Perner (1983), the Sally–Anne test was so named by Simon Baron-Cohen, Alan M. Leslie, and Uta Frith (1985) who developed the test further; in 1988, Leslie and Frith repeated the experiment with human actors (rather than dolls) and found similar results.
