Fig 4. Symptomatology correlations in ASD.

(A) In ASD children, perseverative errors were significantly correlated with anxiety (r₇₂ = 0.34, p = .0040). In ASD adults, (B) perseverative errors were significantly correlated with ADI-R RRB (r₁₁₆ = 0.29, p = .0013). (C) Perseverative errors were further significantly positively related to parent-reported ADHD Hyperactivity/Impulsivity (r₉₄ = 0.32, p = .0017). Win-staying was significantly negatively related to (D) ADI-R RRB (r₁₁₆ = −0.31, p = .0007) and (E) RBS-R Ritualistic-Sameness (r₉₁ = −0.30, p = .0004). In ASD adults, experience decay (ρ) was significantly positively associated with (E) RRB (ADI-R RRB r₁₁₆ = 0.28, p = .0022) as was (F, G) value sensitivity (β; ADI-R RRB r₁₁₆ = −0.29, p = .0019; RBS-R r₉₁ = −0.30, p = .0040). (H, I) Value sensitivity (β) was also significantly negatively correlated with parent-reported ADHD symptomatology (ADHD hyperactivity/impulsivity r₁₁₆ = −0.37, p = .0003; ADHD inattention r₁₁₆ = −0.30, p = .0037).
