Twenty‐four subjects were presented with a series of stimuli, all of equal length (5 in.), and asked to classify each as being or not being 5 in. long. The subjects were then divided into three groups (broad, middle and narrow categorizers) according to the number of including and excluding responses that they gave. It was found that: ( a ) the decision times of both extreme groups were considerably shorter than those of the middle group; ( b ) there was a tendency for the extreme groups to have shorter decision times for their preferred type of response; but this tendency did not reach statistical significance.
