Memory Illusion in High-Functioning Autism and Asperger’s Disorder / Yoko KAMIO in Journal of Autism and Developmental Disorders, 37-5 (May 2007)
[article]
Titre : Memory Illusion in High-Functioning Autism and Asperger’s Disorder Type de document : Texte imprimé et/ou numérique Auteurs : Yoko KAMIO, Auteur ; Motomi TOICHI, Auteur Année de publication : 2007 Article en page(s) : p.867-876 Langues : Anglais (eng) Mots-clés : High-functioning-autism Asperger’s-disorder Memory-illusion Schema Index. décimale : PER Périodiques Résumé : In this study, 13 individuals with high-functioning autism (HFA), 15 individuals with Asperger’s disorder (AD), and age-, and IQ-matched controls were presented a list of sentences auditorily. Participants then evaluated semantically related but new sentences and reported whether they were old or new. The total rates of false recognition for semantically related sentences were similar among the three groups. Nevertheless, memory illusion on some aspects was reduced in HFA participants. These results suggest that HFA have difficulties in semantic association. Although individuals with AD showed no quantitative abnormalities of memory illusion, some contributing factors were atypical. These findings are discussed in terms of schema theory, enhanced perceptual processing hypothesis, and weak central coherence hypothesis.

Titre : Reduced representational momentum for subtle dynamic facial expressions in individuals with autism spectrum disorders Type de document : Texte imprimé et/ou numérique Auteurs : Shota UONO, Auteur ; Wataru SATO, Auteur ; Motomi TOICHI, Auteur Article en page(s) : p.1090-1099 Langues : Anglais (eng) Mots-clés : Autism spectrum disorders Dynamic facial expression Representational momentum Social impairment Index. décimale : PER Périodiques Résumé : Abstract The cognitive mechanisms underlying social communication via emotional facial expressions are crucial for understanding the social impairments experienced by people with autism spectrum disorders (ASD). A recent study (Yoshikawa amp; Sato, 2008) found that typically developing individuals perceived the last image from a dynamic facial expression to be more emotionally exaggerated than a static facial expression; this perceptual difference is termed representational momentum (RM) for dynamic facial expressions. RM for dynamic facial expressions might be useful for detecting emotion in another's face and for predicting behavior changes. We examined RM for dynamic facial expressions using facial expression stimuli at three levels of emotional intensity (subtle, medium, and extreme) in people with ASD. We predicted that individuals with ASD would show reduced RM for dynamic facial expressions. Eleven individuals with ASD (three with Asperger's disorder and eight with pervasive developmental disorder not otherwise specified) and 11 IQ-, age- and gender-matched typically developing controls participated in this study. Participants were asked to select an image that matched the final image from dynamic and static facial expressions. Our results revealed that subjectively perceived images were more exaggerated for the dynamic than for the static presentation under all levels of intensity and in both groups. The ASD group, however, perceived a reduced degree of exaggeration for dynamic facial expressions under the subtle intensity condition. As facial expressions are often displayed subtly in daily communications, reduced RM for subtle dynamic facial expressions may prevent individuals with ASD from appropriately interacting with other people as a consequence of their difficulty detecting others’ emotions.

Titre : Unusual sensory features are related to resting-state cardiac vagus nerve activity in autism spectrum disorders Type de document : Texte imprimé et/ou numérique Auteurs : Kanae MATSUSHIMA, Auteur ; Jun MATSUBAYASHI, Auteur ; Motomi TOICHI, Auteur ; Yasuko FUNABIKI, Auteur ; Takeo KATO, Auteur ; Tomonari AWAYA, Auteur ; Toshihiro KATO, Auteur Article en page(s) : p.37-46 Langues : Anglais (eng) Mots-clés : Autism spectrum disorders Sensory features Parasympathetic nervous system Resting state Heart rate variability Index. décimale : PER Périodiques Résumé : The relationship between unusual sensory features (hyper-reactivity, hypo-reactivity, and unusual sensory interests) and the parasympathetic nervous system in autism spectrum disorder (ASD) has recently garnered interest. The purpose of this study was to investigate whether unusual sensory features are associated with resting-state cardiac vagus nerve activity in ASD children. Electrocardiogram signals were recorded during three 2-min resting periods to quantify the high frequency (HF) component of heart rate variability (HRV) in 37 children with ASD aged 6–12 and 32 typically developing children. Parent-reported questionnaires (Short Sensory Profile, SSP; Social Responsiveness Scale-2, SRS-2) assessed atypical sensory behaviors in daily life and autistic traits. Children with ASD consistently showed lower HF-HRV than typically developing children across the three resting periods. The SSP “Visual/Auditory Sensitivity” score was correlated with resting-state HF-HRV in the ASD group, indicating that ASD children with more severe visual/auditory hyper-reactivity in daily life have lower vagus nerve activity. The SRS-2 “Restricted Interests and Repetitive Behavior” score was also correlated with resting-state HF-HRV in the ASD group. These findings suggest that ASD children with lower vagus nerve activity may have inadequate self-regulatory capacity and difficulty regulating behavioral responses to unpredictable and unavoidable visual/auditory stimuli in daily life.
