Raven's Progressive Matrices are a broadly used tool for measuring cognitive ability. This paper develops and validates a set of nonverbal puzzles that can be viewed as an extension of or substitute for the well-known Ravens tasks. Specifically, we describe the characteristics of our puzzles and provide a calibration of the matrices in terms of response accuracy and response time as a function of these characteristics. Then we directly compare within-subject performance on our puzzles and Ravens tasks. Finally, we replicate a previous experimental paper, substituting our puzzles for the Ravens matrices, and show the two tools have similar predictive success. Our approach offers several benefits due to the relatively large number of novel puzzles of a given difficulty level that can be generated.
