Abstract: An improved method of developing and testing the degree of a student's ability to mentally image a task requiring a motor response. Line diagrams symbolizing objects or maps of actions are presented with instructions that invoke mental images of objects and motor response actions. The students ability to respond to the mental image is measured, recorded and shown to the student only after the response is complete.

Abstract: A method and apparatus for enhancing mental images of data in various visual environments utilizes an electronically generated visual display of an environment including datum references to be acted upon by the subject and a manipulative control which may be manipulated by the subject to electrically record at least two dimensions of an action taken by him to change a highlighted datum reference of the visual display. His action using the manipulatable control in response to the instruction is electronically recorded, and the dimensions of the recorded action are compared with the predetermined stored dimensions for the correct response to the given instruction. The results of the comparison are then presented to the subject. The method and apparatus may utilize concurrently an auditory environment corresponding to the visual environment and the actions taken by the subject may effect concurrent dynamic changes in the visual and/or auditory environments.

Abstract: A method and apparatus for enhancing mental images of data in various visual environments utilizes an electronically generated visual display of an environment including datum references to be acted upon by the subject and means which may be manipulated by the subject to electrically record an action taken by him to change a datum reference of the visual display. His action using the manipulatable means in response to the instruction is electrically recorded invisibly to him. Thereafter, there is presented for comparison an electrically generated visual display including the datum reference as changed by the correct response to the given instruction and the visual display of that reference as changed by his action. The method and apparatus may utilize concurrently an auditory environment corresponding to the visual environment and the actions taken by the subject may effect concurrent change in the visual and/or auditory environments.
