Fig. 1 Graph showing the subjective indifference value for the delayed value of £100 for each delay for each group. ADHD=Attention Deficit Hyperactivity Disorder; ASD=Autism Spectrum Disorder; comorbid: group with both ADHD and ASD. The subjective value of £100 decreases as a function of delay, more steeply in ASD and at a trend-level in the comorbid group relative to controls.

Fig. 2 Horizontal slices showing brain regions that correlated with temporal discounting during delayed choices for each group. (A) Healthy controls, (B) ADHD, (C) ASD and (D) Comorbid ADHD and ASD. Talairach z-coordinates are indicated for slice distance (in mm) from the intercommissural line. The right side of the image corresponds to the right side of the brain.

Fig. 3 Conjunction analysis. Axial slices show brain areas that correlated with temporal discounting during delayed choices in any of the 4 groups. Talairach z-coordinates are indicated for slice distance (in mm) from the intercommissural line. The right side of the image corresponds to the right side of the brain.
