In investigating the mental processes involved in geometry problem solving the present study attempted to eliminate some of the inadequacies of paper and pencil analyses by the following procedure: 1. The stimuli were arranged according to increasing degrees of elaboration and presented to subjects, individually, through an exposure apparatus for a timed interval. 2. The subject expressed his ideas verbally, as they occurred, and these were recorded by a microphone-dictaphone unit. 3. The meanings of the responses were ascertained by cross reference and by use of a controlled set of questions. The data obtained throw light on the status of insight and meaning in this field of subject matter.
