Defining the developmental parameters of temper loss in early childhood: implications for developmental psychopathology / Lauren S. WAKSCHLAG in Journal of Child Psychology and Psychiatry, 53-11 (November 2012)

Thus, characterizing specific behavioral manifestations of temper loss along a dimension from normative misbehaviors to clinically significant problems is an important step toward identifying clinical thresholds. Methods:  Parent-reported patterns of temper loss were delineated in a diverse community sample of preschoolers (n = 1,490). A developmentally sensitive questionnaire, the Multidimensional Assessment of Preschool Disruptive Behavior (MAP-DB), was used to assess temper loss in terms of tantrum features and anger regulation. Specific aims were: (a) document the normative distribution of temper loss in preschoolers from normative misbehaviors to clinically concerning temper loss behaviors, and test for sociodemographic differences; (b) use Item Response Theory (IRT) to model a Temper Loss dimension; and (c) examine associations of temper loss and concurrent emotional and behavioral problems. Results:  Across sociodemographic subgroups, a unidimensional Temper Loss model fit the data well. Nearly all (83.7%) preschoolers had tantrums sometimes but only 8.6% had daily tantrums. Normative misbehaviors occurred more frequently than clinically concerning temper loss behaviors. Milder behaviors tended to reflect frustration in expectable contexts, whereas clinically concerning problem indicators were unpredictable, prolonged, and/or destructive. In multivariate models, Temper Loss was associated with emotional and behavioral problems. Conclusions:  Parent reports on a developmentally informed questionnaire, administered to a large and diverse sample, distinguished normative and problematic manifestations of preschool temper loss. A developmental, dimensional approach shows promise for elucidating the boundaries between normative early childhood temper loss and emergent psychopathology.

Autistic traits and individual brain differences: functional network efficiency reflects attentional and social impairments, structural nodal efficiencies index systemising and theory-of-mind skills / Subhadip PAUL in Molecular Autism, 12 (2021)  

Public ISBD [article]  inMolecular Autism > 12 (2021) . - 3p. Titre : Autistic traits and individual brain differences: functional network efficiency reflects attentional and social impairments, structural nodal efficiencies index systemising and theory-of-mind skills Type de document : Texte imprimé et/ou numérique Auteurs : Subhadip PAUL, Auteur ; Aditi ARORA, Auteur ; Rashi MIDHA, Auteur ; Dinh VU, Auteur ; Prasun K. ROY, Auteur ; Matthew K. BELMONTE, Auteur Article en page(s) : 3p. Langues : Anglais (eng) Mots-clés : Attention  Autism  Dti  Dimensional  Functional connectivity  Graph theory  Social  Theory-of-mind  fMRI Index. décimale : PER Périodiques Résumé : BACKGROUND: Autism is characterised not only by impaired social cognitive 'empathising' but also by superior rule-based 'systemising'. These cognitive domains intertwine within the categorical diagnosis of autism, yet behavioural genetics suggest largely independent heritability, and separable brain mechanisms. We sought to determine whether quantitative behavioural measures of autistic traits are dimensionally associated with structural and functional brain network integrity, and whether brain bases of autistic traits vary independently across individuals. METHODS: Thirty right-handed neurotypical adults (12 females) were administered psychometric (Social Responsiveness Scale, Autism Spectrum Quotient and Systemising Quotient) and behavioural (Attention Network Test and theory-of-mind reaction time) measures of autistic traits, and structurally (diffusion tensor imaging) and functionally (500 s of 2 Hz eyes-closed resting fMRI) derived graph-theoretic measures of efficiency of information integration were computed throughout the brain and within subregions. RESULTS: Social impairment was positively associated with functional efficiency (r = .47, p = .006), globally and within temporo-parietal and prefrontal cortices. Delayed orienting of attention likewise was associated with greater functional efficiency (r = - .46, p = .0133). Systemising was positively associated with global structural efficiency (r = .38, p = 0.018), driven specifically by temporal pole; theory-of-mind reaction time was related to structural efficiency (r = - .40, p = 0.0153) within right supramarginal gyrus. LIMITATIONS: Interpretation of these relationships is complicated by the many senses of the term 'connectivity', including functional, structural and computational; by the approximation inherent in group functional anatomical parcellations when confronted with individual variation in functional anatomy; and by the validity, sensitivity and specificity of the several survey and experimental behavioural measures applied as correlates of brain structure and function. CONCLUSIONS: Functional connectivities highlight distributed networks associated with domain-general properties such as attentional orienting and social cognition broadly, associating more impaired behaviour with more efficient brain networks that may reflect heightened feedforward information flow subserving autistic strengths and deficits alike. Structural connectivity results highlight specific anatomical nodes of convergence, reflecting cognitive and neuroanatomical independence of systemising and theory-of-mind. In addition, this work shows that individual differences in theory-of-mind related to brain structure can be measured behaviourally, and offers neuroanatomical evidence to pin down the slippery construct of 'systemising' as the capacity to construct invariant contextual associations.

Here, we perform a conceptual replication of prior work (Dajani et al. in Sci Rep 6:36566, 2016) in an independent sample of typically developing children (n = 183) and children with autism spectrum disorder (n = 104). Consistent with previous work, the latent profile analysis of parent-report EF measures provided evidence for three EF classes, which exhibited differential proportions of diagnostic groups. Additionally, children in the impaired EF group exhibited greater levels of social impairment. These results highlight the heterogeneity of EF ability among clinical and non-clinical populations and the link between EF and social abilities.
