Differential qualitative performance of delinquents on the Porteus Maze.

Abstract
Groups of 50, delinquents and 50 nondeliquents were given the Revised Porteus Maze Test and Extension. Qualitative (Q) scores on both tests significantly differentiated between deliquents and nondelinquents (p < .001). No sex differences were found on the Q score, indicating that previous results may be generalized to females. Results of the present study support the hypothesis that no significant relationship exists between intelligence, as estimated from the Porteus Quantitative score, and Q score. Evidence is reported which suggests that a non-weighted scoring system is nearly as efficient as the present weighted system of scoring. Interscorer reliability was found to be satisfactory for the Q score (r = .98).
