Previous research suggests that an eyewitness credibility bias can arise when mock jurors are informed of a child's disability diagnosis. The aim of the present study was to examine mock jurors' lie-detection accuracy and credibility perceptions when assessing eyewitness testimonies provided by children diagnosed with an intellectual disability. Adult mock jurors (N = 217; half informed of the child's disability status) read four transcriptions from interviews with children (ages 10 to 15) diagnosed with an intellectual disability before evaluating the credibility and truthfulness of each eyewitness report. The mock jurors' lie-detection accuracy of the eyewitness reports produced by children with an intellectual disability (55.76%) was found to be similar to prior lie-detection research involving typically developing populations. Furthermore, there were no differences in the lie-detection accuracy and credibility ratings between mock-jurors who were informed of the child's disability when compared to those who were not informed. Although mock jurors perceived the children's testimony to have low credibility, they seemed reluctant to consider many of these testimonies to be false. The current findings also suggest that the disclosure of a disability may not independently cause worsened perceptions of child eyewitnesses.

Purpose: To evaluate sex differences in autistic traits in youth born extremely preterm (EP; 23-27 weeks) who were later diagnosed with autism spectrum disorder (ASD) at 10-years.

Method: A longitudinal cohort design from the Extremely Low Gestational Age Newborn Study (ELGAN) followed N = 857 EP infants from birth through 10-years. EP infants later diagnosed with ASD (N = 61, 20 females) participated in the study. Group differences were evaluated via inferential and Bayesian statistics (values > 1 suggest evidence for alternate hypothesis) on ASD screeners (M-CHAT at 2-years, SCQ and SRS-2 at 10-years), and gold-standard diagnostic measures (ADOS-2, ADI-R) at 10-years.

Results: Males scored significantly higher than females on measures of Social Affect from the ADOS-2, t(34.27)=-2.20, BF₁₀ = 2.33, and measures of Repetitive and Restricted Behaviors from the ADI-R, t(40.52)=-2.85, BF₁₀ = 5.26. Bayesian estimates suggested marginal evidence for sex differences in Nonverbal Communication, t(30.66)=-1.81, BF₁₀ = 1.25, and Verbal Communication, t(24.64)=-1.89, BF₁₀ = 1.39, from the ADI-R, wherein males scored higher than females. No statistically significant sex differences were identified on any of the ASD screeners at 2 (M-CHAT) or 10 years (SCQ). No significant sex differences were observed on any subscales of the SRS at 10 years.

Conclusions: EP autistic males present with more autistic traits than EP autistic females on gold-standard diagnostic measures of autism at 10-years of age, despite not presenting with higher autistic traits on screeners at either age. These results align with sex differences observed in full-term, autistic youth. These results suggest ASD screeners may under identify autism in EP youth, particularly females.

Gilliam Autism Rating Scale-Third Edition (GARS-3) serves as an effective screening tool for autism spectrum disorder (ASD) that is based on the latest and authoritative diagnostic criteria, however, there is a deficiency in adaptive research in China. We aimed to revise the Chinese version of GARS-3 (CV-GARS-3) and evaluate its psychometric characteristics, providing a theoretical basis for the improvement of ASD screening tools in China. This study developed CV-GARS-3 through translation and cultural adaptation of GARS-3. 362 ASD individuals, 126 typical development individuals, and 103 individuals with other disorders were recruited to analyze the psychometric characteristics of CV-GARS-3. The results showed that exploratory structural equation model demonstrated satisfactory goodness-of-fit. Within the non-verbal ASD samples, all items loaded on anticipated factors. Regarding verbal ASD samples, 3 items exhibited considerable cross-loadings and were categorized under unexpected factors. Meanwhile, acceptable criterion validity was reflected in the four subscales (r = 0.71) and the six subscales (r = 0.74). Satisfactory reliability was observed in the four subscales (Cronbach's α = 0.96, inter-rater consistency = 0.86, test-retest consistency = 0.87) and the six subscales (Cronbach's α = 0.94, inter-rater consistency = 0.81, test-retest consistency = 0.81). In addition, receiver operating characteristic analysis demonstrated that both the four subscales (sensitivity = 89%, specificity = 85%, accuracy = 88%) and the six subscales (sensitivity = 86%, specificity = 88%, accuracy = 86%) had outstanding screening effects. Therefore, the results suggested that the CV-GARS-3 is considered as a useful tool for the screening and auxiliary diagnosis of ASD. Notably, the expression of scale should be further improved to adapt the context of Chinese culture and achieve more precise diagnostic results.

Autistic individuals and law enforcement officers are likely to engage under various circumstances within the community. Therefore, law enforcement officers require training on supporting those with autism and better understanding autistic behaviors. Aims for this study include: (1) developing and delivering high quality professional development on autism spectrum disorder (ASD) to support autistic individuals during encounters with law enforcement officers, and (2) examining how law enforcement officers respond to the professional development session. For this study a four-hour, in-person training on autism for law enforcement officers was developed. Law enforcement officers (n = 27) attended the training session. Subsequently, participants completed an open-ended survey gathering perceptions related to the topics covered in the training, thoughts on the feasibility and applicability of content, and transfer to future safety encounters involving autistic individuals. Data was analyzed using a qualitative approach including concept driven thematic coding with constant comparisons. Data yielded themes on experiences with the autistic community, strategies learned from the training, thoughts on specific content, and feedback on the training format. Overall, law enforcement officers reported they felt better prepared, more knowledgeable on the autistic community, and believed the strategies were feasible and applicable to the field. These findings point to the importance of training on autism and that law enforcement officers found it was time well spent. Future directions include examining how training transfers to practice in the field and ways to connect law enforcement officers with the autistic community outside of emergency response.

Recent theoretical accounts suggest that differences in the processing of probabilistic events underlie the core and associated traits of autism spectrum disorder (ASD). These theories hypothesize that autistic individuals are differentially impacted by disruptions in probabilistic input relative to neurotypical peers. According to this view, autistic individuals assign disproportionate weight to prediction errors such that novel input is overweighted relative to the aggregation of prior input; this is referred to as 'hyperplasticity' of learning. Prediction among autistic individuals has primarily been examined in nonverbal, visual contexts with older children and adults. The present study examined 32 autistic and 32 cognitively-matched neurotypical (NT) children's ability to generate predictions and adjust to changes in predictive relationships in auditory stimuli using two eye gaze tasks. In both studies, children were trained and tested on an auditory-visual cue which predicted the location of a reward stimulus. In Experiment 1 the cue was non-linguistic (instrumental sound) whereas in Experiment 2 the cue was linguistically-relevant (speaker gender). In both experiments, the cue-reward contingency was switched after the first block of trials, and predictive behavior was evaluated across a second block of trials. Analyses of children's looking behavior revealed similar performance in both groups on the non-linguistic task (Exp. 1). In the linguistically-relevant task (Exp. 2), predictive looking was less disrupted by the contingency switch for autistic children than NT children. Results suggest that autistic children may demonstrate hyperplastic learning in linguistically-relevant contexts, relative to NT peers.

Difficulties in controlling emotions - a proxy for emotion dysregulation (ED)-and difficulties in expressing feelings in words-'absence of emotion labelling' or alexithymia-co-exist in autism and contribute to elevated levels of impulsive and suicidal behaviour. To date, studies linking the two phenomena have relied on retrospective self-reported measures, lacking support for generalizability to real-life situations. The present study investigated in vivo emotion labelling and its impact on emotion control in 29 autistic adults without intellectual disability (ASC) and 28 neurotypical (NT) individuals of similar age, sex, and educational level. Participants were trained in an Ecological Momentary Assessment (EMA) to label their emotions, the arousal dimension, and their emotion control via smartphone over a one-week period. Findings showed that the ASC group experienced more instances of 'having an emotion that I cannot name' and, when they were able to label their emotions, they reported higher rates of negative and conflicting (simultaneously positive and negative) emotions. In both groups, the absence of emotion labelling, and intense negative emotions were associated with impaired emotion control. However, the association between lack of emotional awareness-'I have no emotion'-and impaired emotion control was only evident in ASC individuals. Our study highlights a nuanced facet of emotional processing in the ASC population. Further research is needed to gain a deeper understanding of the complex relationship between ED and alexithymia in autism.

Autism Spectrum Disorder (ASD) is on the rise worldwide with an increasing acknowledgement that its continuum of care to enhance participation should be multidisciplinary. The International Classification of Functioning, Disability, and Health (ICF) and its derivatives ICF - Children and Youth (ICF - CY) and ICF Core Sets have been increasingly used among health professionals to enhance communication and documentation of outcomes. This study aimed at investigating the comprehensiveness of the ICF - CY and ICF Core Sets with regard to occupational therapy goals and the extent of participation representation in these goals. Forty occupational therapists working with children with ASD stated their most common three long-term goals. The goals were then mapped to the ICF - CY two level classification. The percentage of goals reflecting "Participation" was calculated. The overlap between ICF - CY and the ICF ASD Core Sets was assessed. A total of 155 goals were extracted, of which only seven (4.5%) related to sensory processing were not linked to the ICF - CY categories. 35.1% of the total linked goals were regarded as reflecting "Participation". 84.5% of ICF - CY categories overlapped with the ICF ASD Core Sets. Categories related to hand function, and taking care of body parts were found to be lacking in the ICF ASD Core Sets. The ICF - CY and the ICF ASD Core Sets may be feasible clinical tools for children with ASD, however, they may not be sufficient to cover occupational therapy goals. Goals also need to be modified to better reflect participation.

Over the past ten years, there has been a significant improvement in the sensibility and specificity of the earlier diagnosis of ASD. However, parenting traits were relatively explored among children with different disabilities. We aimed to clarify the characteristics of parent-child interaction among children with ASD and DLD, compared with children not diagnosed with a disability. The study recruited 280 children aged 1.5-3.9 years (30 children with ASD, 48 children with DLD, and 202 TD children) and their primary caregivers. Parent-child interaction was measured based on video recordings and observation. One-way ANOVA was used for the comparison of IRS-C scores among the three groups, and the t-test was used for pairwise comparisons; effect size was also calculated. Children's age and sex were further considered as grouping category in our analyses. All comparison models were adjusted by demographic background (i.e. child age and sex, sibling, main caregiver, mother education, and family annual income). Children with ASD showed the lowest level of general social competence compared to children with DLD (d = 1.298, P < 0.001) and TD group (d = 1.833, P < 0.001). Children with DLD showed less responsiveness (d = 0.780, P < 0.001) and less empathy (d = 0.706, P < 0.001) than TD children. Caregivers of children with ASD also showed the lowest level of parenting attributes relative to caregivers of children with DLD (d = 0.978, P < 0.001) and caregivers of TD children (d = 0.860, P < 0.001). The child- and parent-related traits also varied by child age and sex. We posit that parent-child interaction necessitates greater attention with respect to early screening and identification.

There is no validated screening measure for children with high-functioning autism spectrum disorder (ASD) in Korea. The purpose of the present study was (1) to examine the reliability and validity of the Korean version of the Autism Spectrum-Child (K-AQ-Child); (2) to find the optimal cut-off value of the K- AQ-Child in the Korean population. A total of 144 children aged 4-11 years (male 80.6%, mean age = 7.05 ± 1.75) were recruited in this study, with 72 in the high-functioning ASD group and 72 in the non-clinical Control group. The Cronbach's alpha coefficient of the K-AQ-child was 0.962, showing excellent internal consistency. For discriminant validity, the ASD group scored significantly higher than the Control group on the total score and all the scores of the subdomains of the K-AQ-Child after controlling for sex. Significant positive correlation between total scores of the K-AQ-Child and the K-SCQ was found. The optimal cut-off value of 58.5 yielded a sensitivity of 0.931 and specificity of 0.986. K-AQ-Child is a valid and reliable measure to quantify autistic traits and identify the high-risk individuals for further diagnostic evaluation in intellectually capable children aged 4-11 years. It would be useful for both clinical practice and research purposes.Clinical Trial Registration The trial was registered at the Clinical Research Information Service (CRIS) of Republic of Korea (Registration Number: KCT0008907).

Most studies in children with autism spectrum disorder (ASD) support a decrement in imitation performance. Factors related to visual attention and motor execution have been proposed to explain this phenomenon in ASD. However, studies investigated imitation with various methods, leading to inconsistent findings. Here, we examine imitation performance related to visual attention and motor execution. We focused on the imitation of meaningful and meaningless gestures, consistently reported as more affected than imitation of actions with objects in ASD. The imitation eye-tracking task consisted of a video of an actor demonstrating gestures and prompting children to imitate them. The demonstrations comprised meaningful and meaningless hand gestures, and meaningless facial gestures. We measured the fixation duration to the actor' face during child-directed speech and gesture demonstrations. We video-recorded children to assess their performance. Our sample comprised 100 participants (3.55 ± 1.11 years old), including 84 children with ASD. The ASD and typically developing groups displayed the same visual attention toward gesture demonstrations, although children with ASD spent less time looking at the face during facial stimuli. Visual exploration of actors' gestures did not influence imitation performance. Imitation of meaningful gestures was associated with less severe autistic symptoms, whereas imitation of meaningless gestures was correlated with higher non-verbal cognitive and fine-motor skills. These findings contribute to a better understanding of the complexity of imitation. We delineated the distinct nature of imitation of meaningful and meaningless gestures in children with ASD. We discuss clinical implications in relation to assessment and intervention programs.
