ABSTRACT:
An electronic matching circuit for use in teaching, having a plurality of contact pairs interconnected through an interchangeable and programmable matrix. One contact of each pair corresponds to a stimulus and the other contact of each pair to a response. A pair of decision probes are engaged with selected stimulus and selected response contacts. A momentary contact switch is depressed and one of two visual indicators is illuminated to display when a correct or incorrect response, respectively, has been chosen. Digital logic in conjunction with the decision probes determines which color indicator is energized.
