In the study of antagonistic visual habits (Fritz, J. Comparative Psycho!., 1930, 11, 171-184), it is necessary to devise a method whereby certain selected habits directly oppose each other. Each learned act must have a counterpart in an antagonistic act so as to produce .interference. Such a system of mutually exclusive habits can be arranged by means of the card sorting technique. Fifty playing cards are glued to a board in a pattern so that when the board is turned around (180 degrees), the numbers (pips) will be the same but the suits reversed, that is, black and red suits interchanged. In this way a high possibility of confusion can be created, yet two definite patterns of learning are maintained. The card-sorting board and the technique of administering will be demonstrated.
