| Abstract | Alternating series, in which 1 set of relevant cues appears at odd-numbered trials and another set at even-numbered trials, were contrasted with constant series, in which the same relevant cues appear at every training trial. The principal result was the interaction on both training trials and test trials between type of series and the number of stimulus dimensions changing from trial to trial. For alternating series, the group in which 1 stimulus dimension changed between each pair of adjacent training trials showed fewer errors (p < .01) than the group in which 3 dimensions changed. In the case of constant series, the group in which 3 dimensions changed displayed fewer errors (p < .01) than the group in which just 1 changed.
