Conversely, 16 children with ASD with robust intellectual development since age 2 (IQ = 100 ± 3; 12.0 ± 0.4 years old [±SD]) learned typically but showed early-onset CRs only during long-delay EBC (0.8 SD pre-TD) unrelated to hypoplasia of any measured brain area. Using 16 EBC measures, binary LR classified ASD and TD with 80% accuracy (95% CI = 72–88%), 81% sensitivity (95% CI = 69–92%), and 79% specificity (95% CI = 68–91%); multinomial LR more accurately classified children based on ID (94% accuracy, 95% CI = 89–100%) than ASD severity (85% accuracy, 95% CI = 77–93%). Separate analyses of 39 children with MRI (2.1 ± 0.3 years old [±SD]) indicated that cerebellar hypoplasia did not predict ASD + ID over ages 2–4 (Cohen d = 0.3) compared with early-onset CRs during age 11 trace EBC (Cohen d = −1.3).Discussion Trace EBC reveals the relationship between cerebellar hypoplasia and ASD + ID likely by engaging cerebrocerebellar circuits involved in intellectual ability and implicit timing. Follow-up prospective studies using associative learning can determine whether ID can be predicted in children with early ASD diagnoses.ASD=autism spectrum disorder; CS=conditioned stimulus; DAS=Differential Abilities Scale; EBC=eye-blink conditioning; ID=intellectual disability; LR=logistic regression; MSEL=Mullen Scales of Early Learning; TD=typical development; US=unconditioned stimulus
