Porteus Maze The Porteus Maze test (PMT), whose original instructions for administration are in English, is an intelligence test designed to assess and predict intellectual capacity in children, adolescents and adults. It is a nonverbal performance test. It was developed by Stanley Porteus, a professor of psychology at the University of Hawaii, and adapted to our country by Beglan Toğrol. The Porteus mazes test consists of mazes of varying difficulty that can be administered between 15-30 minutes. In the test application, it is expected to reach the exit point of the maze by following the rules such as not entering dead ends with the line drawn with a pencil and not crossing the lines.
APPLICATION AND INSTRUCTIONS
Individual: The arrow sign in each porteus maze is shown
- Start drawing from here,
- Return to the starting point in a straight line,
- Let's go.
A standardized instruction is given. Pencil and paper with labyrinths are used during the practice. Each porteus maze is called an age maze. The practice starts with the 3-year-old maze and continues until the 14-year-old maze. The interruption and scoring is determined by the mistakes made during the test. Taking the wrong path, crossing the line will result in deducting points from that age maze or not getting any points at all, as well as getting zero points from two age mazes in a row will cause the intelligence test to be interrupted and IQ will be calculated with the scores obtained up to that point. Until the 11th age maze, 2 attempts, i.e. errors, are allowed, and from the 12th age maze onwards, 4 attempts are allowed.
AREAS WHERE THE PORTEUS TEST IS USED:
Porteus mazes are used as IQ tests in psychiatric diagnoses as well as in the diagnosis of neurological disorders. Typical test behaviors and scores are reported in patients with head trauma and neurological problems in the brain.
RELIABILITY OF THE PORTEUS INTELLIGENCE TEST
The Porteus test has been reported to be accurate in various controlled studies, in test-retest analyses and in comparison with other test results such as Weshler (WISC-R) and Binet. It is a test that can be administered with simple materials without language and cultural difference problems and gives the intelligence level as a general IQ score.
