Description: The Porteus Maze Test is a nonverbal performance test of intelligence. It was developed by Stanley Porteus, professor of psychology at the University of Hawaii. This test is a supplementary sub-test of the Wechsler intelligence scales. These tests are designed to check the individual’s ability to use planning, patience and mental alertness in novel, specific performance tasks. The Porteus maze test can also measure social skills and adaptability. The Porteus maze test is particularly accurate at distinguishing lower levels of cognitive ability. It has been found that poor performance in the maze test is related to attention deficit hyperactivity disorder, substance abuse, and other behavioral disorders related to insufficient executive function (especially inhibition and planning).

It is a set of gradual paper forms on which objects can track the way from the starting point to the exit. Subjects must avoid alleys along the way. no time limit. The complexity of the maze varies from simple diamonds for ordinary three-year-old to complex mazes for adults. There are three sets of mazes: the original maze (Vineland series) and two supplements, expansion and supplement.

Scoring: Participants’ scores were obtained by summing up errors, including touch lines in the maze, bending at corners, and errors in lifting a pen or finger. It also measures the time required to complete the test. The mental age score is calculated according to standard procedures. Two scores are involved: a test quota (TQ), which is assumed to be used to measure nonverbal forward-looking and planning ability, and a qualitative (Q) score based on the style and quality of test performance. Scoring results in qualitative or Q scores and test age.

Validity: Many early studies of the correlation with other intelligence tests ranged from medium to high. Since Porteus is a non-verbal proficiency test, it cannot be expected to have a high correlation with a pure language test, but the correlation should be at least moderately positive. The researchers pointed out that the correlation coefficient .50 represents the results of other IQ tests. The relevance is particularly high with intelligence tests involving spatial abilities (such as Kohs Blocks and Knox Cubes).

Suggested Uses: The reviewer does not recommend this test for clinical use, but suggests that further research is needed to verify the author’s claim.
