The most important of these conclusions concerns an apparent correlation of two distinct groups of mental traits on the one hand with a relative preponderance (in the experiments) of kinaesthetic or colour influences on the other. Thus where kinaesthesis or colour appreciation predominates in the interpretation of the blots, we find respectively (p. 69):
