ABSTRACT:
A system for preschool screening of children through a series of question and answer routines presented via an audiovisual console. The console has a slide display of graphic information and an audio instruction to the child typically to select one of a plurality of figures displayed by activation of a corresponding, adjacent button. Additionally, the child may be asked to count a predetermined number through button activations, to respond to the visual display through selected lenses in a hood for vision testing, or to receive audio instructions through a set of earphones which are selectively attenuated in earphone volume to determine hearing acuity. The screening system has a logic control operative in response to coded instructions which are stored in a set of registers from a magnetic tape system. The magnetic tape system also provides the control of audio and visual information for an entire series of tests. The logic control is designed to take special cognizance of characteristics of the youthful child operator in responding to his or her particular button pushes or lack thereof, and to provide an indication of the answer sequence to the magnetic tape system for recording on an answer tape in association with a series of coded comments which may be entered by an adult supervisor.
