The investigation was concerned with an analogue of extraversion—introversion in rats as precursor to a selective breeding experiment. Forty Maudsley reactive and forty Maudsley non‐reactive rats were tested in both the Mowrer box and in a spatial alternation T‐maze. It is argued that each of these test situations gives a measure of extraversion—introversion through the involvement of reactive inhibition in each case (cf. Eysenck, 1955, 1957). Both measures exhibited strain differences; but comparison of the scores of individual subjects also suggested individual differences that can be attributed to differences in stimulus hunger.
