Autism spectrum disorder in China differs considerably from autism spectrum disorder in the West in terms of prevalence estimates, education opportunities, and life outcomes of autistic people. The lack of autism spectrum disorder awareness could be a key factor underlying the disparities. To date, there has been no evaluation of autism spectrum disorder knowledge among the general public of China. Using the Autism Stigma and Knowledge Questionnaire developed for use in diverse cultural contexts, this study uncovered profoundly different public views about autism spectrum disorder in China compared with the United States. Determined by cognitive diagnosis modeling, 86%–91% of the surveyed U.S. citizens ( N = 1127) achieved adequate autism spectrum disorder knowledge in diagnosis/symptoms, etiology, and treatment, whereas for the Chinese citizens ( N = 1254) the percentages were only 57%–65%. Moreover, 14% of the participants from the United States were classified to endorse autism spectrum disorder stigma; in comparison, 38% of the Chinese participants endorsed autism spectrum disorder stigma. The Chinese citizens displayed knowledge deficits primarily in the areas of autism spectrum disorder core symptoms, comorbid intellectual impairment, and prognosis. Sociodemographic factors associated with the Chinese citizen’s misconceptions included gender, ethnicity, social economic factors, among others. These results have important implications for increasing public awareness and promoting community participation for autistic individuals in China. Lay abstract ASD in China differs considerably from ASD in the West in terms of prevalence estimates, education opportunities and life outcomes of autistic people. The lack of ASD awareness could be a key factor underlying these disparities. We asked 1127 U.S. citizens and 1254 Chinese citizens about their autism knowledge using the Autism Stigma and Knowledge Questionnaire (ASK-Q).The results indicated profoundly different public views about ASD in China compared to the U.S. Specifically, only 57%-65% of the Chinese citizens demonstrated adequate ASD knowledge compared to 86%-91% in the U.S. citizens. Fourteen percent of the U.S. citizens were shown to hold stigma beliefs towards ASD; in comparison, 38% of the Chinese citizens indicated ASD stigma. The Chinese citizens displayed misconceptions about ASD related to symptoms, causes, and possible long-term outcomes. In China but not in the U.S., male citizens and citizens with lower social economic status were more likely to have misconceptions about ASD than others were. The findings of this research can help increase public awareness about ASD and create a more inclusive environment for autistic people in China.

The present study investigated pitch processing in Mandarin-speaking children with autism using event-related potential measures. Two experiments were designed to test how acoustic, phonetic and semantic properties of the stimuli contributed to the neural responses for pitch change detection and involuntary attentional orienting. In comparison with age-matched (6-12 years) typically developing controls (16 participants in Experiment 1, 18 in Experiment 2), children with autism (18 participants in Experiment 1, 16 in Experiment 2) showed enhanced neural discriminatory sensitivity in the nonspeech conditions but not for speech stimuli. The results indicate domain specificity of enhanced pitch processing in autism, which may interfere with lexical tone acquisition and language development for children who speak a tonal language.

Hearing aid use was associated with a decrement in involuntary attention switch to distractors in the auditory selective attention task. RMQ training led to gains in speech perception in noise and improved listener confidence in the auditory selective attention task.

Although many studies have reported domain-general impaired duration perception for speech and nonspeech sounds in children with autism, it remained unclear whether this phenomenon is universally applicable regardless of language background. In some languages such as Finnish and Japanese, vowel duration serves a phonemic role that can signify semantic distinction, and in others (e.g., Mandarin Chinese), vowel duration does not carry this phonemic function. The present event-related potential study investigated neural sensitivity to duration contrasts in speech and nonspeech contexts in Mandarin-speaking children with autism and a control group of age-matched typically developing (TD) children. A passive oddball paradigm was adopted to elicit the mismatch negativity (MMN) and involuntary orienting response (P3a) for change detection. A pure tone condition and a vowel condition were used. The MMN results showed that the autism group had diminished response amplitude and delayed latency in the pure tone condition compared to the TD group, whereas no group difference was found in the vowel condition. The P3a results showed no significant between-group MMN difference in the pure tone condition. In the vowel condition, the autism group had smaller P3a than the TD group. Together, the distinct patterns of discrimination and orienting responses for duration contrasts in pure tones and vowels are consistent with the 'allophonic perception' theory for autism, which may reflect a compromised perceptual weighting system for speech learning.

BACKGROUND:The purpose of this study was to assess the short-term effi cacy of a 4-week ultrasound curriculum taught by American fi rst-year medical students to general practitioners working in public health care clinics, or puskesmas, in Bandung, Indonesia. METHODS:We performed a prospective, observational study of Indonesian health care practitioners from public clinics in Bandung, Indonesia. These practitioners were enrolled in a 4-week ultrasound training course taught by first-year American medical students. A total of six sessions were held comprising of 38 ultrasound milestones. A pre-course and post-course written exam and practical exam was taken by each participant. RESULTS:We enrolled 41 clinicians in the course. The average pre-course exam score was 35.2% with a 2.4% pass rate, whereas the average post-course exam score was 82.0% with a 92.7% pass rate. The average practical score at the completion of the course was 83.2% (SD=0.145) with 82.9% of the class passing (score above 75.0%). CONCLUSION:Our data suggests that first-year medical students can effectively teach ultrasound to physicians in Indonesia using a 4-week intensive ultrasound training course. Future studies are needed to determine the amount of training required for profi ciency and to evaluate the physicians' perceptions of the student-instructors' depth of knowledge and skill in point of care ultrasound.
