The Porteus Maze Test in the measurement of reflection/impulsivity.

This study investigated the use of the Porteus Maze test as a measure of reflection/impulsivity when used with both normal and retarded subjects. Study 1 (N = 90) provided sample data for three equal groups of 30 adolescent students in the regular school. These were defined as above average, average, and below average in general intelligence. In addition to measures of qualitative and quantitative scoring, data were also available from Kagan's Matching Familiar Figures Test and a specially constructed Teachers' Rating Scale. The below-average group showed a significantly more impulsive approach. There was evidence of the concurrent validity of Porteus Maze as shown in substantial correlations with the other variables. Study 2 investigated the use of the Porteus Maze with 41 mildly intellectually handicapped adolescents. The data were in keeping with those obtained from a below-average group in Study 1.
