Porteus Maze Test: Non-verbal planning test

Series of printed paper mazes of increasing difficulty. Stanley Porteus (Australian psychologist working at the Vineland Training School in New Jersey) developed the maze test in 1915 as a non-verbal measure of planning, foresight, and impulse control. The test is still occasionally used in modern neuropsychology.

About the Porteus Maze Test

Stanley Porteus arrived at the Vineland Training School in 1915 to work on cognitive assessment of children with intellectual disabilities. Goddard's translation of the Binet-Simon scale was already in use at Vineland, but Goddard and others felt it underestimated the children's practical abilities. Porteus's solution was a non-verbal test that required no spoken or written language: a series of printed mazes of increasing complexity.

The Porteus Maze Test contained 12 mazes ranging from very simple (year 3 difficulty) to very hard (adult difficulty). The subject traced a path from entrance to exit without crossing any walls or backing up. Scoring was based on the highest maze successfully completed within reasonable time limits. The test measured planning, foresight, motor control, and impulse inhibition.

The Porteus Maze Test was widely incorporated into other batteries: it appeared in the Army Beta (1918) as Test 1, in the Pintner Non-Language Mental Test (1920), and in numerous clinical batteries through the 1960s. It is still occasionally used in modern neuropsychology, particularly for assessing executive function in children and patients with frontal-lobe damage.

About this interactive version: The Porteus Maze Test requires the subject to trace a path through printed mazes with a pencil. Web browsers cannot accurately measure the precision and self-corrections required by the original scoring. We describe the procedure and show sample mazes.

The 1 subtests

#1
12 mazes of graded difficulty Mazes range from simple year-3 difficulty (single decision point) to complex adult difficulty (15+ decision points, multiple dead ends). Subject traces a path from entrance to exit. Scoring is the highest maze successfully completed in reasonable time without crossings or backing up.

Public domain. Stanley Porteus (1883-1972) was an Australian-trained psychologist who joined the Vineland Training School (the same institution where Henry Goddard had translated the Binet-Simon scale). The Maze Test was later widely used in clinical neuropsychology under the names Porteus Maze and (more recently) the Wisconsin Card Sorting Test as a measure of executive function.
