Table 3.

Multiple regressions predicting principal component scores (from explicit action ratings) from the two multidimensional scaling (MDS) dimensions (from sorting task).

Predictor	Model 1: Component 1 (magnitude of arm movement)			Model 2: Component 2 (configuration of the hand)

	β	Direction cosine	t	β	Direction cosine	t
1^st dimension (x)	-.25	-0.68	-2.07^*	-.53	-0.93	-4.94^***
2^nd dimension (y)	-.28	-0.73	-2.24^*	.22	0.37	2.00⁺

Note: direction cosines for each model are normalized β values whose sum of squares equals 1.
