Callous-unemotional traits moderate executive function in children with ASD and ADHD: A pilot event-related potential study.

ABSTRACT: Attention deficit hyperactivity disorder (ADHD) and autism spectrum disorder (ASD) are associated with varied executive function (EF) difficulties. Callous-unemotional (CU) traits, a proposed antecedent of adult psychopathy, are often associated with intact or enhanced EF. Here we test whether CU traits may therefore modulate EF in ASD and ADHD, in which EF is typically impaired. We collected CU traits and measured event-related potentials (ERPs) that index EF during a cued-continuous performance test (CPT-OX) in boys with ASD, ADHD, comorbid ASD+ADHD and typical controls. We examined attentional orienting at cues (Cue-P3), inhibitory processing at non-targets (NoGo-P3) and conflict monitoring between target and non-target trials (Go-N2 vs. NoGo-N2). In children with ASD, higher CU traits were associated with an enhanced increase in N2 amplitude in NoGo trials compared to Go trials, which suggests relatively superior conflict monitoring and a potential cognitive strength associated with CU traits. The results emphasise the importance of considering the effects of co-occurring traits in the assessment of heterogeneity of EF profiles in neurodevelopmental disorders.

Project description:Callous-unemotional (CU) traits are characterized by a lack of responsiveness to the emotions of others, particularly negative emotions. A parenting environment where the child's own distress emotions are sensitively responded to may help foster the child's ability to respond to the emotions of others. We tested whether maternal sensitivity to distress, and other parenting characteristics, were associated with CU traits over the preschool period, and examined whether this was mediated via infant attachment status.In an epidemiological cohort, CU traits were assessed at age 2.5, 3.5, and 5.0 years by mother report. Dimensions of parenting were assessed in free play at age 29 weeks in a stratified subsample of 272, and attachment status at 14 months (n = 265). Structural equation modelling with maximum likelihood estimation was used to examine predictions from parenting dimensions and attachment status.A parenting factor comprised of sensitivity to distress (n = 207), sensitivity to non-distress, positive regard toward the infant (or warmth), and intrusiveness, predicted child CU traits (p = .023). This effect was accounted for mainly by sensitivity to distress (p = .008) and positive regard (p = .023) which showed a synergistic effect as evidenced by a significant interaction (p = .01). This arose because the combination of low sensitivity to distress and low positive regard created the risk for elevated CU traits. Although sensitivity and positive regard predicted attachment security and disorganization, there were no associations between attachment status and CU traits.The finding of contributions from both sensitivity to distress and positive regard to reduced CU traits suggests that children's responsiveness to others' emotions may be increased by their own mothers' responsiveness to them and their mothers' warmth. There was no evidence that this was mediated via attachment status. Implications for intervention and future directions are discussed.
