Selected bivariate correlations between putative predictors and shape bias performance at Visit 4.

Variable	TD shape bias n = 33	ASD shape bias n = 29	High verbal ASD shape bias n = 15	Low verbal ASD shape bias n = 14
Proportion of nouns understood characterized as solid + shape	.06 a	−.28b	−.27 c	−.19
Proportion of nouns understood characterized as nonsolid + material	.16 a	.15 b	.52* c	−.31
Average RJA time	−.12	.23	−.26	0.47
Average IJA time	.22	.41*	.19	.66*

Note. TD = typically developing; ASD = autism spectrum disorder; RJA = responding to joint attention; IJA = initiating joint attention; PA = passive attention.
