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.
