A developmental increase in allostatic load from ages 3 to 11 years is associated with increased schizotypal personality at age 23 years / Melissa PESKIN in Development and Psychopathology, 23-4 (November 2011)  

Public ISBD [article]  inDevelopment and Psychopathology > 23-4 (November 2011) . - p.1059-1068 Titre : A developmental increase in allostatic load from ages 3 to 11 years is associated with increased schizotypal personality at age 23 years Type de document : Texte imprimé et/ou numérique Auteurs : Melissa PESKIN, Auteur ; Adrian RAINE, Auteur ; Yu GAO, Auteur ; Peter H. VENABLES, Auteur ; Sarnoff A. MEDNICK, Auteur Année de publication : 2011 Article en page(s) : p.1059-1068 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Although allostatic load has been investigated in mood and anxiety disorders, no prior study has investigated developmental change in allostatic load as a precursor to schizotypal personality. This study employed a multilevel developmental framework to examine whether the development of increased allostatic load, as indicated by impaired sympathetic nervous system habituation from ages 3 to 11 years, predisposes to schizotypal personality at age 23 years. Electrodermal activity to six aversive tones was recorded in 995 subjects at age 3 years and again at 11 years. Habituation slopes at both ages were used to create groups who showed a developmental increase in habituation (decreased allostatic load), and those who showed a developmental decrease in habituation (increased allostatic load). Children who showed a developmental increase in allostatic load from ages 3 to 11 years had higher levels of schizotypal personality at 23 years. A breakdown of total schizotypy scores demonstrated specificity of findings to cognitive–perceptual features of schizotypy. Findings are the first to document a developmental abnormality in allostasis in relation to adult schizotypal personality. The relative failure to develop normal habituation to repeated stressors throughout childhood is hypothesized to result in an accumulation of allostatic load and consequently increased positive symptom schizotypy in adulthood.

Genetic covariance between psychopathic traits and anticipatory skin conductance responses to threat: Evidence for a potential endophenotype / Pan WANG in Development and Psychopathology, 27-4 (Part 1) (November 2015)  

Public ISBD [article]  inDevelopment and Psychopathology > 27-4 (Part 1) (November 2015) . - p.1313-1322 Titre : Genetic covariance between psychopathic traits and anticipatory skin conductance responses to threat: Evidence for a potential endophenotype Type de document : Texte imprimé et/ou numérique Auteurs : Pan WANG, Auteur ; Yu GAO, Auteur ; Joshua ISEN, Auteur ; Catherine TUVBLAD, Auteur ; Adrian RAINE, Auteur ; Laura A. BAKER, Auteur Année de publication : 2015 Article en page(s) : p.1313-1322 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : The genetic architecture of the association between psychopathic traits and reduced skin conductance responses (SCRs) is poorly understood. By using 752 twins aged 9–10 years, this study investigated the heritability of two SCR measures (anticipatory SCRs to impending aversive stimuli and unconditioned SCRs to the aversive stimuli themselves) in a countdown task. The study also investigated the genetic and environmental sources of the covariance between these SCR measures and two psychopathic personality traits: impulsive/disinhibited (reflecting impulsive–antisocial tendencies) and manipulative/deceitful (reflecting the affective–interpersonal features). For anticipatory SCRs, 27%, 14%, and 59% of the variation was due to genetic, shared environmental, and nonshared environmental effects, respectively, while the percentages for unconditioned SCRs were 44%, 2%, and 54%. The manipulative/deceitful (not impulsive/disinhibited) traits were negatively associated with both anticipatory SCRs (r = –.14, p < .05) and unconditioned SCRs (r = –.17, p < .05) in males only, with the former association significantly accounted for by genetic influences (rg = –.72). Reduced anticipatory SCRs represent a candidate endophenotype for the affective–interpersonal facets of psychopathic traits in males.

Is it avoidance or hypoarousal? A systematic review of emotion recognition, eye-tracking, and psychophysiological studies in young adults with autism spectrum conditions / Hélio Clemente CUVE in Research in Autism Spectrum Disorders, 55 (November 2018)

These hypotheses suggest that ERD in ASC can be explained by either exacerbated physiological arousal to eye-contact interfering with emotion recognition, or blunted arousal not engaging the necessary attention and awareness mechanisms to process emotionally salient cues, respectively. Most studies have suggested that individuals with ASC display an overall reduced attention to the eyes, however, this was not always associated with ERD, and some studies also reported ERD with no evidence of atypical gaze patterns. The evidence from psychophysiological studies is also mixed. While some studies supported that individuals with ASC are hypoaroused during emotion processing, others reported hyperarousal or even partially supported both. Overall, these results suggest that the current autonomic arousal and gaze hypotheses cannot fully account for ERD in ASC. A new integrative model is proposed, suggesting a two-pathway mechanism, in which avoidance and orientation processes might independently lead to ERD in ASC. Current methodological limitations, the influence of alexithymia, and implications are discussed.

Reduced electrodermal fear conditioning from ages 3 to 8 years is associated with aggressive behavior at age 8 years / Yu GAO in Journal of Child Psychology and Psychiatry, 51-5 (May 2010)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 51-5 (May 2010) . - p.550-558 Titre : Reduced electrodermal fear conditioning from ages 3 to 8 years is associated with aggressive behavior at age 8 years Type de document : Texte imprimé et/ou numérique Auteurs : Yu GAO, Auteur ; Adrian RAINE, Auteur ; Peter H.

Methods: Using a differential, partial reinforcement conditioning paradigm, electrodermal activity was recorded from 200 male and female children at ages 3, 4, 5, 6, and 8 years. Antisocial/aggressive and hyperactive-inattentive measures were collected at age 8. Results: Poor electrodermal fear conditioning from ages 3 to 8 years was associated with aggressive behavior at age 8 in both males and females. Conclusions: Results indicate that the relationship between poor fear conditioning and aggression occurs early in childhood. Enhanced electrodermal fear conditioning may protect children against future aggressive/violent behavior. Abnormal amygdala functioning, as indirectly assessed by fear conditioning, may be one of the factors influencing the development of childhood aggression.

The Utility of the Child and Adolescent Psychopathy Construct in Hong Kong, China / Annis LAI-CHU-FUNG in Journal of Clinical Child & Adolescent Psychology, 39-1 (January-February 2010)

A confirmatory factor analysis observed a good fit for the three-factor model (callous-unemotional, impulsivity, narcissism) of APSD, with boys scoring higher than girls on narcissism and callous-unemotional traits. Modest construct validity was found with regard to expected relationships with internalizing and externalizing behavior problems. The previously observed higher scores on callous-unemotional traits in boys at older ages were replicated. Findings suggest that child psychopathy may be applicable in a non-Western culture, although the callous-unemotional factor may have a different meaning in China.
