Picture Completion

An attempt was made to score picture completion records obtained from 118 delinquents. The I. Q. of 74 of these 118 were almost uniformly distributed over the range of 65 to 79.9 inclusive. In the completion test there is a possibility of 369 moves. The 118 cases made 360 of them as opposed to 349 made by Pintner and Anderson's normal subjects. Arbitarily a value of 100 was assigned to certain parts (pictures) in the test. The remaining 61 situations were turned over to each one of eight instructors or advanced students with the request that each position be rated. When these ratings were brought together, in many instances the values assigned to a final position varied so little among members of the group that a simple average was accepted as final value. When a divergence was great, discussion was obtained and the simple average gave us the accepted final weight. A correlation of the standings with the intelligent quotients was calculated--the Pearson coefficient being .41. From Psych Bulletin 18:05:00303.
