ANTIQUE 1918 WOOD LITHO IQ TEST C H STOELTING ILLUSTRATED MARGUERITE DAVIS This IQ test was printed in 1918 by the C.H. Stoelting Company of Chicago. It is classified as a "picture context instrument" designed to test cognitive abilities through non-verbal means. The kit includes two square panels printed with pictures depicting a sequence of events in a boy's life. The pictures tell a story in narrative style, each scene building on the previous one. Each illustration has a small pocket for a missing image which completes the story being told by the picture. For example, the first picture in the sequence shows the boy sitting on the edge of an unmade bed, wearing only one shoe, and reaching for an unknown item on the floor. Along with the two larger picture panels, the kit includes many small pieces to be inserted into the panels' pockets. These pieces have a variety of images designed to complete the story being told on the panels. The picture panels gradually increase in difficulty, and some of the picture pieces are nearly identical. The test's original manual, available in the Stoelting company's archives, gives explicit directions on its administration, even suggesting the exact words to be spoken to the tested individual. Twenty minutes were allowed to complete the test. William Healy, the test's developer, claimed that "one of the most brilliant men in America took the full 20 minutes and wanted more in which to finish . . . finally leaving a piece in place that gave a total score of 90." The perfect score is 100, tallied by adding up numbers printed on the backs of the small pieces.The Stoelting Company was founded around 1886 and is probably the oldest psychological testing company still in existence in the United States.
