This test provides two types of measures. One, it evaluates the child’s ability to make left-right discriminations on his own body. During the first part, the test shows a child “sitting” in the same orientation as the subject (i.e., the subject sees on the screen the back of the child) in front of two objects, one on his/her upper left and the other on his/her upper right visual field. The computer asks the subject to “grab” the left or right object using his/her left or right hand. What is measured is (1) the time taken to select an arm (by clicking at the shoulder), and (2) whether the selected arm was correct or wrong. The same procedure is repeated during the second part of the test, in which the orientation of the child on the screen is reversed, i.e., the child on the screen is facing the subject. The second type of measures are derived from Piaget’s (19) tests to evaluate awareness of right-left relations outside our own body, i.e., in the environment. To evaluate this ability, the test measures (1) the time taken by the subject to decide which object to “grab” and (2) the number of correct/wrong decisions.
