Anxiety and Interpretation of Ambiguity in Autistic Children, Typical Children and Their Mothers / Louise NEIL in Journal of Autism and Developmental Disorders, 49-3 (March 2019)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 49-3 (March 2019) . - p.1035-1047 Titre : Anxiety and Interpretation of Ambiguity in Autistic Children, Typical Children and Their Mothers Type de document : texte imprimé Auteurs : Louise NEIL, Auteur ; Hannah WHITE, Auteur ; Katy WARREN, Auteur ; Elizabeth PELLICANO, Auteur Article en page(s) : p.1035-1047 Langues : Anglais (eng) Mots-clés : Anxiety  Autism  Child  Cognition Index. décimale : PER Périodiques Résumé : Anxiety is highly prevalent in autistic children. Yet interpretation biases implicated in anxiety in non-autistic individuals have received little research attention in this group. Twenty-two autistic children and 25 typical children completed an ambiguous scenarios interview and questionnaire-based measures of anxiety. A subsample of mothers completed parent-report and adult relevant versions of the interview and anxiety questionnaires. Autistic children self-reported similar interpretations of ambiguous scenarios, and similar levels of anxiety, to their typical peers. In contrast, mothers of autistic children reported greater levels of anxiety, and more negative interpretations of ambiguous scenarios in both their children and themselves, relative to mothers of typical children. These data highlight the importance of including autistic children's self-reports when measuring and treating anxiety.

Binocular rivalry in children on the autism spectrum / Themis KARAMINIS in Autism Research, 10-6 (June 2017)  

Public ISBD [article]  inAutism Research > 10-6 (June 2017) . - p.1096-1106 Titre : Binocular rivalry in children on the autism spectrum Type de document : texte imprimé Auteurs : Themis KARAMINIS, Auteur ; Claudia LUNGHI, Auteur ; Louise NEIL, Auteur ; David BURR, Auteur ; Elizabeth PELLICANO, Auteur Article en page(s) : p.1096-1106 Langues : Anglais (eng) Mots-clés : binocular rivalry  autism  perception  bistable perception  vision  atypical development Index. décimale : PER Périodiques Résumé : When different images are presented to the eyes, the brain is faced with ambiguity, causing perceptual bistability: visual perception continuously alternates between the monocular images, a phenomenon called binocular rivalry. Many models of rivalry suggest that its temporal dynamics depend on mutual inhibition among neurons representing competing images. These models predict that rivalry should be different in autism, which has been proposed to present an atypical ratio of excitation and inhibition [the E/I imbalance hypothesis; Rubenstein & Merzenich, 2003]. In line with this prediction, some recent studies have provided evidence for atypical binocular rivalry dynamics in autistic adults. In this study, we examined if these findings generalize to autistic children. We developed a child-friendly binocular rivalry paradigm, which included two types of stimuli, low- and high-complexity, and compared rivalry dynamics in groups of autistic and age- and intellectual ability-matched typical children. Unexpectedly, the two groups of children presented the same number of perceptual transitions and the same mean phase durations (times perceiving one of the two stimuli). Yet autistic children reported mixed percepts for a shorter proportion of time (a difference which was in the opposite direction to previous adult studies), while elevated autistic symptomatology was associated with shorter mixed perception periods. Rivalry in the two groups was affected similarly by stimulus type, and consistent with previous findings. Our results suggest that rivalry dynamics are differentially affected in adults and developing autistic children and could be accounted for by hierarchical models of binocular rivalry, including both inhibition and top-down influences.

Childhood maltreatment is associated with lower exploration and disrupted prefrontal activity and connectivity during reward learning in volatile environments / Louise NEIL ; Vincent VALTON ; Harriet PHILLIPS ; Georgia RANKIN ; Molly SHARP ; Jessica RAPLEY ; Essi VIDING ; Jonathan P.

MCCRORY, Auteur Article en page(s) : p.846-856 Langues : Anglais (eng) Mots-clés : Maltreatment  internalising disorder  neuroimaging  learning Index. décimale : PER Périodiques Résumé : Background Atypical reward processing is implicated in a range of psychiatric disorders associated with childhood maltreatment and may represent a latent vulnerability mechanism. In this longitudinal study, we investigated the impact of maltreatment on behavioural and neural indices of reward learning in volatile environments and examined associations with future psychopathology assessed 18 months later. Methods Thirty-seven children and adolescents with documented histories of maltreatment (MT group) and a carefully matched group of 32 non-maltreated individuals (NMT group) aged 10 16 were presented with a probabilistic reinforcement learning task featuring a phase of stable and a phase of volatile reward contingencies. Brain activation and connectivity were assessed simultaneously using functional magnetic resonance imaging (fMRI). Computational models were used to extract individual estimates of learning rates and temperature, and neural signals in prespecified regions of interest were analysed during volatile and stable environments. In regression analyses, behavioural measures and neural signals at baseline were used to predict psychological symptoms at follow-up. Results The MT group showed lower behavioural exploration, which predicted decreased internalising symptoms at follow-up. The MT group had lower activation in the orbitofrontal cortex (OFC) during outcome delivery in volatile relative to stable contexts. OFC connectivity with an area in the mid-cingulate cortex was also lower during outcome processing, which predicted higher general psychopathology at follow-up. Conclusions These findings are consistent with the notion that low exploratory behaviour following childhood maltreatment is potentially a protective adaptation against internalising symptoms, while disrupted neural processing of reward learning in volatile environments may index latent vulnerability to mental illness.

The Psychometric Properties of a New Measure of Sensory Behaviors in Autistic Children / Louise NEIL in Journal of Autism and Developmental Disorders, 47-4 (April 2017)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 47-4 (April 2017) . - p.1261-1268 Titre : The Psychometric Properties of a New Measure of Sensory Behaviors in Autistic Children Type de document : texte imprimé Auteurs : Louise NEIL, Auteur ; Dido GREEN, Auteur ; Elizabeth PELLICANO, Auteur Article en page(s) : p.1261-1268 Langues : Anglais (eng) Mots-clés : Sensory  Questionnaire  Sensory behaviors  Sensory sensitivities  Autism Index. décimale : PER Périodiques Résumé : Unusual reactions to sensory input became part of the diagnostic criteria for autism spectrum disorder in the DSM-5. Measures accurately assessing these symptoms are important for clinical decisions. This study examined the reliability and validity of the Sensory Behavior Questionnaire, a parent-report scale designed to assess frequency and impact of sensory behaviors in autistic children. The scale demonstrated excellent internal consistency and concurrent validity, and was a better predictor of autistic symptoms than the Short Sensory Profile within a group of 66 school-age autistic children. The scale also successfully discriminated between autistic and typical children of similar age and ability. The Sensory Behavior Questionnaire has potential as a measure of sensory behaviors in children on the autism spectrum.

The Relationship Between Intolerance of Uncertainty, Sensory Sensitivities, and Anxiety in Autistic and Typically Developing Children / Louise NEIL in Journal of Autism and Developmental Disorders, 46-6 (June 2016)

Intolerance of uncertainty and anxiety explained approximately half the variance in autistic children’s sensory sensitivities, but only around a fifth of the variance in typical children’s sensory sensitivities. In children with autism only, intolerance of uncertainty remained a significant predictor of children’s sensory sensitivities once the effects of anxiety were adjusted for. Our results suggest intolerance of uncertainty is a relevant construct to sensory sensitivities in children with and without autism.
