Age-Related Differences in Response to Music-Evoked Emotion Among Children and Adolescents with Autism Spectrum Disorders / K. G. STEPHENSON in Journal of Autism and Developmental Disorders, 46-4 (April 2016)

SOUTH, Auteur Année de publication : 2016 Article en page(s) : p.1142-1151 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder  Music  Anxiety  Emotion  Development  Skin conductance  response Index. décimale : PER Périodiques Résumé : While research regarding emotion recognition in ASD has focused primarily on social cues, musical stimuli also elicit strong emotional responses. This study extends and expands the few previous studies of response to music in ASD, measuring both psychophysiological and behavioral responses in younger children (ages 8–11) as well as older adolescents (ages 16–18). Compared to controls, the ASD group demonstrated reduced skin conductance response to music-evoked emotion. Younger groups, regardless of diagnosis, showed greater physiological reactivity to scary stimuli than to other emotions. There was a significant interaction of age group and diagnostic group in identifying scary music stimuli, possibly evidencing disrupted developmental trajectories in ASD for integrating physiological and cognitive cues that may underlie symptoms of anxiety.

Index. décimale : PER Périodiques Résumé : Background: Functional neuroimaging research in autism spectrum disorder has reported patterns of decreased long-range, within-network, and interhemispheric connectivity. Research has also reported increased corticostriatal connectivity and between-network connectivity for default and attentional networks. Past studies have excluded individuals with autism and low verbal and cognitive performance (LVCP), so connectivity in individuals more significantly affected with autism has not yet been studied. This represents a critical gap in our understanding of brain function across the autism spectrum. Methods: Using behavioral support procedures adapted from Nordahl, et al. (J Neurodev Disord 8:20-20, 2016), we completed non-sedated structural and functional MRI scans of 56 children ages 7-17, including LVCP children (n = 17, mean IQ = 54), children with autism and higher performance (HVCP, n = 20, mean IQ = 106), and neurotypical children (NT, n = 19, mean IQ = 111). Preparation included detailed intake questionnaires, video modeling, behavioral and anxiety reduction techniques, active noise-canceling headphones, and in-scan presentation of the Inscapes movie paradigm from Vanderwal et al. (Neuroimage 122:222-32, 2015). A high temporal resolution multiband echoplanar fMRI protocol analyzed motion-free time series data, extracted from concatenated volumes to mitigate the influence of motion artifact. All participants had > 200 volumes of motion-free fMRI scanning. Analyses were corrected for multiple comparisons. Results: LVCP showed decreased within-network connectivity in default, salience, auditory, and frontoparietal networks (LVCP < HVCP) and decreased interhemispheric connectivity (LVCP < HVCP=NT). Between-network connectivity was higher for LVCP than NT between default and dorsal attention and frontoparietal networks. Lower IQ was associated with decreased connectivity within the default network and increased connectivity between default and dorsal attention networks. Conclusions: This study demonstrates that with moderate levels of support, including readily available techniques, information about brain similarities and differences in LVCP individuals can be further studied. This initial study suggested decreased network segmentation and integration in LVCP individuals. Further imaging studies of LVCP individuals with larger samples will add to understanding of origins and effects of autism on brain function and behavior.

Overactive Pattern Separation Memory Associated with Negative Emotionality in Adults Diagnosed with Autism Spectrum Disorder / M. SOUTH in Journal of Autism and Developmental Disorders, 45-11 (November 2015)

(Journal of Autism and Developmental Disorders 44(9):2355–2362. doi:10.1007/s10803-014-2105-y, 2014) have suggested that a specific memory impairment in autism spectrum disorders (ASD) arises from hippocampal failure to consolidate multiple related pieces of information. Twenty-four adults diagnosed with ASD and matched healthy controls completed a pattern separation memory task that is known to critically depend on hippocampal involvement. They additionally completed questionnaires regarding anxiety, depression, and behavioral motivation. Specific deficits in pattern separation were significantly correlated with negative emotionality; the best predictor of memory deficit was from a measure of achievement motivation that has also been associated with hyperactivity and impulsivity. In the context of impaired emotion regulation in ASD, there is a need for integrated cognitive, affective, and neural systems approaches to build targeted interventions.

Separate contributions of autistic traits and anxious apprehension, but not alexithymia, to emotion processing in faces / K. G. STEPHENSON in Autism, 23-7 (October 2019)  

Public ISBD [article]  inAutism > 23-7 (October 2019) . - p.1830-1842 Titre : Separate contributions of autistic traits and anxious apprehension, but not alexithymia, to emotion processing in faces Type de document : Texte imprimé et/ou numérique Auteurs : K. G. STEPHENSON, Auteur ; S. G. LUKE, Auteur ; M. SOUTH, Auteur Article en page(s) : p.1830-1842 Langues : Anglais (eng) Mots-clés : alexithymia  anxious apprehension  autism  emotion  eye fixation  eye tracking  mixed-effects modeling  worry Index. décimale : PER Périodiques Résumé : Reduced eye fixation has been commonly reported in autistic samples but may be at least partially explained by alexithymia (i.e., difficulty understanding and describing one's emotional state). Because anxiety is often elevated in autism, and emotion-processing differences have also been observed in anxious samples, anxiety traits may also influence emotion processing within autism. This study tested the contribution of dimensional traits of autism, anxious apprehension, and alexithymia in mediating eye fixation during face processing. Participants included 105 adults from three samples: autistic adults (AS; n = 30), adults with clinically elevated anxiety and no autism (HI-ANX; n = 29), and neurotypical adults without elevated anxiety (NT; n = 46). Experiment 1 used an emotion identification task with dynamic stimuli, while Experiment 2 used a static luminance change detection task with emotional- and neutral-expression static photos. The emotions of interest were joy, anger, and fear. Dimensional mixed-effects models showed that autism traits, but not alexithymia, predicted reduced eye fixation across both tasks. Anxious apprehension was negatively related to response time in Experiment 1 and positively related to eye fixation in Experiment 2. Attentional avoidance of negative stimuli occurred at lower levels of autism traits and higher levels of worry traits. The results highlight the contribution of autism traits to emotional processing and suggest additional effects of worry-related traits.
