Figure 4

Results from between-group comparisons. Significant activations using cluster-based thresholding determined by Z > 2.3 and a corrected cluster significance threshold of p = 0.05. Areas in red depict regions where the control children showed greater positive linear relations between cortical activity and task difficulty level than the ASD group. There were no areas where the ASD group showed greater linear activation trends across difficulty level in the negative or positive direction than controls. Prec precuneus, DLPFC dorsolateral prefrontal cortex, dmPMC dorsal medial premotor cortex.
