Using data from 189 Japanese community-based children, this study examined whether autistic traits at age 5 were related to emotional/behavioral outcomes at age 7. The results showed that prior autistic traits were subsequently associated with all emotional/behavioral domains. After controlling for baseline emotional/behavioral scores autistic traits continued to predict later emotional symptoms and peer problems. This study highlights that in addition to clinical ASD, it is also important to focus on subthreshold autistic traits in preschool children for better subsequent emotional/behavioral outcomes.

Attitudes toward risk and ambiguity in patients with autism spectrum disorder / J. FUJINO in Molecular Autism, 8 (2017)  

Public ISBD [article]  inMolecular Autism > 8 (2017) . - 45p.

TAKAHASHI, Auteur Article en page(s) : 45p. Langues : Anglais (eng) Mots-clés : Ambiguity  Autism spectrum disorder  Decision-making  Gain  Loss  Risk  Uncertainty Index. décimale : PER Périodiques Résumé : Although the ability to make optimal decisions under uncertainty is an integral part of everyday life, individuals with autism spectrum disorder (ASD) frequently report that they experience difficulties with this skill. In behavioral economics, researchers distinguish two types of uncertainty to understand decision-making in this setting: risk (known probabilities) and ambiguity (unknown probabilities). However, it remains unclear how individuals with ASD behave under risk and ambiguity, despite growing evidence of their altered decision-making under uncertainty. We therefore extended previous research by studying the attitudes of those with ASD toward risk and ambiguity in both positive and negative contexts (i.e., gain and loss). In gain contexts, no significant difference was observed between the groups in risk attitudes, but ambiguity aversion was attenuated in ASD. In loss contexts, ambiguity attitudes did not significantly differ between the groups, but the ASD participants were less risk-seeking compared with the controls. In addition, insensitivity to the context change under risk and ambiguity in ASD was both significantly associated with poor social skills. These results improve our understanding of altered decision-making under uncertainty by disentangling the attitudes toward risk and ambiguity in ASD individuals. Applying behavioral economic tools may provide insights into the mechanisms underlying behavioral disturbances in ASD.

Egocentric biases and atypical generosity in autistic individuals / S. TEI in Autism Research, 12-11 (November 2019)  

Public ISBD [article]  inAutism Research > 12-11 (November 2019) . - p.1598-1608 Titre : Egocentric biases and atypical generosity in autistic individuals Type de document : Texte imprimé et/ou numérique Auteurs : S. TEI, Auteur ; J. FUJINO, Auteur ; T. ITAHASHI, Auteur ; Yuta AOKI, Auteur ; H. OHTA, Auteur ; M. KUBOTA, Auteur ; R. I. HASHIMOTO, Auteur ; M. NAKAMURA, Auteur ; N. KATO, Auteur ; H. TAKAHASHI, Auteur Article en page(s) : p.1598-1608 Langues : Anglais (eng) Mots-clés : autism spectrum disorders  decision making  egocentrism  perspective taking  social cognition Index. décimale : PER Périodiques Résumé : Individuals with autism spectrum conditions (ASCs) often experience difficulty and confusion in acknowledging others' perspectives and arguably exhibit egocentricity. However, whether this egocentricity necessarily results in selfish behavior during social situations remains a matter of debate. To study this relationship, we used computerized visuospatial perspective-taking task (VPT) and social-discounting task (SDT), derived from cognitive psychology and behavioral economics, and examined egocentric and other-oriented judgments in participants with ASCs (mean age 29.0 +/- 4.2 years) and a group of matched typically developing (TD) controls (30.8 +/- 8.5). The response time in VPT showed altered perspective-taking in the ASCs group compared with the TD group that involved in enhanced self-other intrusion and condition-insensitive response. Regardless of self/other perspective judgments, responses were relatively slower and consistent in duration in the ASCs group compared with the TD group. Social discounting was attenuated rather than steep discounting in the ASCs group. Their discounting was comparatively more consistent, irrespective of the task condition (i.e., self-other closeness-level). In effect, ASCs group exhibited more generous decisions than the TD group in this task. Finally, those with more egocentric perspective intrusion in VPT paradoxically showed more generous behaviors in SDT in the ASCs group. Our findings suggest that having ASCs does not always exhibit selfish behavior during interpersonal communication. Reduced flexibility in distinguishing self/other perspective and shifting decision-rules might account for this unique relationship between egocentricity and apparently generous behaviors. These results extend the recent suggestion that more careful attention should be paid to the idea of egocentricity in individuals with ASCs. Autism Res 2019. (c) 2019 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: We aimed to examine whether seeing the world from another person's point of view and being generous toward other people are related in autistic and nonautistic people. We used a visual perspective-taking task and a social task in which individuals made decisions about how to divide a sum of money with others. Our results suggest that being autistic does not always make someone bad at seeing the world from another's viewpoint, and that autistic people may make fairer social decisions toward unfamiliar people because of lower bias.

Relationship between physiological and parent-observed auditory over-responsiveness in children with typical development and those with autism spectrum disorders / H. TAKAHASHI in Autism, 22-3 (April 2018)

Mean acoustic startle response magnitudes in response to 65-105 dB stimuli, in increments of 10 dB, were analyzed in children with autism spectrum disorders and with typical development. Average peak startle latency was also examined. We examined the relationship of these acoustic startle response measures to parent-reported behavioral sensory processing patterns in everyday situations, assessed using the Sensory Profile for all participants. Low-threshold scores on the Sensory Profile auditory section were related to acoustic startle response magnitudes at 75 and 85 dB, but not to the lower intensities of 65 dB. The peak startle latency and acoustic startle response magnitudes at low-stimuli intensities of 65 and 75 dB were significantly related to the low-threshold quadrants (sensory sensitivity and sensation avoiding) scores and to the high-threshold quadrant of sensation seeking. Our results suggest that physiological assessment provides further information regarding auditory over-responsiveness to less-intense stimuli and its relationship to caregiver-observed sensory processing abnormalities in everyday situations.

Stability of Autistic Traits from 5 to 8 Years of Age Among Children in the General Population / Hideyuki HARAGUCHI in Journal of Autism and Developmental Disorders, 49-1 (January 2019)

The current study compared autistic traits assessed by a mother-reported quantitative measure, the Social Responsiveness Scale, at age 5 and 8 years and examined the intraclass correlation coefficients of scores across the period for 168 Japanese community-based children. Results showed that total and two subdomain-related autistic trait scores remained primarily stable in males and females. This stability was observed for both children with higher and lower autistic traits scores with a possible sex-specific pattern. Our findings suggest that autistic traits in the general population can be reliably assessed using quantitative measures for this age period.
