Complexity contrast. A. Non-autistic > autistic contrast (in blue): increased activity in left middle frontal gyrus and bilateral precuneus as complexity increased. AUT > non-AUT contrast (in red): increased activity in the left superior occipital gyrus and the left middle occipital gyrus as complexity increased (p < 0.001 unc, K = 50 contiguous voxels). B, C, D. Percent signal change in the three regions of between-group differences displayed for each task complexity level, in the autistic group (in red) and non-autistic group (in blue).
