Porteus Maze Test performance: Relationships with MRI findings in a neuropsychiatric population

Delay of gratification, Porteus maze test performance, and behavioral adjustment in a delinquent group.

This study explored the relationships among a behavioral and verbal measure of delay of gratification, Porteus Maze Test measures of planning ability and foresight (TQ) and impulse control (Q), and ratings of adjustment in a school for delinquent adolescent males. Both measures of delay of gratification were significantly related to the Porteus measures and the adjustment ratings. Delay of grat...

MRI Findings in Patients with TMJ Click

Introduction: It has been shown that joint click, an initial and common finding in internal derangement (ID), respond to neither conservative treatment nor surgical intervention. This raises the question as to whether it must be treated in the absence of other pertinent signs and symptoms, so the aim of this study was to investigate and compare the MRI findings of TMJ in both normal subjects an...

Heritability and Longitudinal Stability of Planning and Behavioral Disinhibition Based on the Porteus Maze Test

The Porteus Maze Test (PMT) provides measures of planning and behavioral disinhibition. The PMT was administered to 941 twins during Wave 1 (9-10 years) and 320 twins during Wave 2 (11-13 years). Participants were drawn from the University of Southern California Risk Factors for Antisocial Behavior Study (RFAB). Heritability of behavioral disinhibition, determined by PMT Q-Score, were 33% at Wa...

A factorial investigation of scores on the Porteus Maze.

The history of the Porteus Maze Test begins in the period between 1913 and 1915 when it was firsc proposed as a measure to extend the score obtainable wich the early Binet test of intelligence (Porteus, 1959). Porteus uses the analogy of a worked-out mine to point out thac, as a measure of intellect, the use of a single score, thin, 15-min. mencal ability scale has had its day. He feels that ma...
