Three predictions from the model of extraversion put forward by Brebner & Cooper (1974) were tested in a simple RT task. In line with the model, extraverts were found to make more commissive errors and to be more affected by an increase in the catch‐trial rate. The third prediction‐that extraverts would tend to produce longer runs of decreasing RTs than of increasing RTs in the condition with 10 per cent catch‐trials, was not borne out. This effect was, however, seen in the condition with 40 per cent catch‐trials although it was not statistically significant, P = 0.06.
