Callous-unemotional traits and fearlessness: A cardiovascular psychophysiological perspective in two adolescent samples using virtual reality / Nicholas D. THOMSON in Development and Psychopathology, 32-3 (August 2020)

Titre : Callous-unemotional traits and fearlessness: A cardiovascular psychophysiological perspective in two adolescent samples using virtual reality Type de document : Texte imprimé et/ou numérique Auteurs : Nicholas D. THOMSON, Auteur ; Steven M. GILLESPIE, Auteur ; Luna C. M. CENTIFANTI, Auteur Article en page(s) : p.803-815 Langues : Anglais (eng) Mots-clés : Callous-unemotional traits fearlessness pre-ejection period respiratory sinus arrhythmia Index. décimale : PER Périodiques Résumé : There has been a longstanding debate about the link between callous-unemotional traits and fearlessness. However, biological evidence for a relationship in adolescents is lacking. Using two adolescent samples, we measured emotional reactivity and cardiac measures of sympathetic (pre-ejection period) and parasympathetic (respiratory sinus arrhythmia) reactivity during 3D TV and virtual reality fear induction. Study 1 included 62 community adolescents from a stratified sample. Study 2 included 60 adolescents from Emotional and Behavioral Difficulties schools. Results were consistent across both studies. Adolescents with high callous-unemotional traits showed coactivation of the sympathetic and parasympathetic nervous system. Consistent with these results, youths with callous-unemotional traits self-reported that they felt more in control after the fear induction. Thus, in both samples, youth with callous-unemotional traits displayed a physiological and emotional profile suggesting they maintained control during fear induction. Therefore, it is proposed here that a shift in thinking of youth with callous-unemotional traits as fearless to youth with callous-unemotional traits are better able to manage fearful situations, may be more appropriate.

Titre : Greater fear reactivity and psychophysiological hyperactivity among infants with later conduct problems and callous-unemotional traits Type de document : Texte imprimé et/ou numérique Auteurs : William R. MILLS-KOONCE, Auteur ; Nicholas J. WAGNER, Auteur ; Michael T. WILLOUGHBY, Auteur ; Cynthia STIFTER, Auteur ; Clancy BLAIR, Auteur ; Douglas A. GRANGER, Auteur ; Investigators THE FAMILY LIFE PROJECT KEY, Auteur Article en page(s) : p.147-154 Langues : Anglais (eng) Mots-clés : Fearlessness psychobiology autonomic cortisol conduct problems callous-unemotional traits Index. décimale : PER Périodiques Résumé : Background Approximately one third of children who meet criteria for conduct problems (CP) are also characterized by elevated callous-unemotional (CU) traits. This subgroup is at elevated risk for more pervasive and extreme levels of later antisocial behavior and has been characterized by a fearlessness temperament and blunted stress psychophysiology at older ages. The objective of this study was to examine group differences in fear reactivity and stress psychophysiology in infancy among children classified as having CP with CU (CP + CU), CP without CU (CP only), or no CP in later childhood. Methods A birth cohort study (n = 1,292) was followed longitudinally from birth through first grade. Behavioral fear, baseline heart period (HP) and respiratory sinus arrhythmia (RSA), and pretask, 20-min posttask, and 40-min posttask salivary cortisol were assessed at 6 and 15 months of age around a fear challenge task. CP and CU were assessed by maternal report at first grade and children were classified into CP and CU groups if they scored in the upper 10th percentile of these ratings. Results No group differences were observed in children at 6 months of age. However, at 15 months of age children with later CP + CU displayed greater high-intensity fear behavior, higher pretask and overall cortisol levels, and lower levels of HP and RSA compared to children with CP only and children with no CP. Conclusions The discrepancy between the biobehavioral correlates of conduct problems with callous-unemotional traits in infancy and those reported from studies of older children and adults suggests that the etiology of this behavioral phenotype may be more complex than a simple genetic maturation model.
