Abstract
Abstract A psychological teaching apparatus is described having a cover plate and successively therebeneath a question analysis sheet, a spacer plate, an answer key plate, and a series of electrical contacts, a series of aligned holes in said cover plate and spacer plate representative of the questions to be answered and corresponding holes in the answer key plate representative of the answers to such questions, the series of electrical contacts beneath the holes of the answer key plate being connectable with an electrical probe passing through the answer key plate, and a series of lights electrically connected to said probe and said electrical contacts to become actuated upon contact of the probe with each said contact for successive questions.

Claim 1
Independent Claim
303 words
A psychological teaching apparatus having a base supporting a series of overlying layers comprising: a A cover plate provided with multiplicity of holes arranged in lines and at least two columns for indicating a succession of answers to successive questions; b An item analysis sheet of paper spaced beneath said cover plate and containing indicia thereon, contiguous thereto and adapted to be punctured by a probe passing through said cover plate; c A spacer beneath said item analysis sheet provided with a series of holes therethrough corresponding to and in vertical alignment with said holes in said cover plate; d An answer key plate beneath said spacer plate provided with holes corresponding to answers to successive questions programmed thereon; e A series of electrical contacts beneath said answer key plate in alignment with each of said holes corresponding to the succession of answers programmed on said answer key plate; f A probe connected to a source of power and at least one source of light for penetrating the holes of said cover plate, item analysis sheet, spacer plate, and answer key plate to make contact with said electrical contacts upon selection of the answers to the respective questions on said item analysis sheet and programmed on said answer key plate; and g Two sources of light on the top of said base in parallel alignment with each successive line of holes corresponding to programmed answers, the first source of light being provided for each line of holes in said cover plate for illumination each time said probe contacts said electrical contacts corresponding to said line and the second source of light for each line of said holes being controlled by an individual switch for permitting activation of each second source of light, said individual switches being located on a side of said base.
