Mirror drawing test is used to measure

The Mirror Drawing Test is a standard laboratory apparatus and psychomotor assessment tool used extensively in educational psychology to measure the transfer of learning (or cross-education/bilateral transfer) and habit formation.In this test, a subject traces a star or complex geometric pattern while viewing their hand and the target sheet solely through a mirror image inversion. Performing the task with one hand and tracking subsequent efficiency gains in the unpracticed hand demonstrates the transfer of learning.
