Mental Rotation of Random Two-Dimensional Shapes

Cooper, Lynn A.

Cognitive Psychology, 7, 1, 20-43, Jan 75

In two experiments subjects were required to determine whether a random, angular form, presented at any of a number of picture-plane orientations was a "standard" or "reflected" version. Average time required to make this determination increased linearly with the angular departure of the form from a previously learned orientation. (Author/BJG)
