Matching Familiar Figures Test

n. An instrument designed to measure a cognitive dimension of reflection versus impulsivity in which subjects are shown a picture of a familiar object and are required to select which of six other pictures are identical to the original one. The latency and accuracy of the response are recorded. Those who are slower than median and above the median in accuracy are deemed reflective. Those who are quicker than the median and make more than the median number of errors are deemed impulsive. Those who are quicker than the median and make fewer errors than the median are called quick, and those who are slower and make more errors than the median are called slow. The test does not theoretically account for those who are in the quick and slow categories.
