On the Gift Delay task children could receive a score from 1 to 5 (1 = removes cover and looks inside box; 2 = looks in window but does not remove cover; 3 = touches box or cover without looking inside; 4 = looks at (but not inside) the box and does not touch box or cover; 5 = never touches or looks at or inside the box). ANT task accuracy refers to proportion of correct trials.
