Relations between verb factivity and first-order and second-order false belief understanding: Evidence from Mandarin-speaking typically developing children and children with autism spectrum disorders.

This study examined relations between verb factivity and first-order and second-order FB reasoning in 156 four- to seven-year-old typically developing (TD) Mandarin-speaking children, and in 17 children with autism spectrum disorders (ASD) and 17 TD matched controls. Children's understanding of a factive zhīdào 'know', a non-factive juédé 'think' and a counter-factive jiǎzhuāng 'pretend' was assessed by a truth value judgement task. For TD children, zhīdào 'know' (factive) significantly predicted their first-order and second-order FB performances, and jiǎzhuāng 'pretend' (counter-factive) significantly predicted their first-order FB performance. For autistic children, they performed significantly poorer than their TD counterparts on complementation, verb factivity, first-order and second-order FB, and their first-order FB performance was significantly related to jiǎzhuāng 'pretend' (counter-factive). The findings suggest that verb factivity relates to both first-order and second-order FB, and verbs differing in factuality and mental state status contribute differently to ToM development.

ConclusionsAlthough, based on the current literature, differential cognitive biases may not be a marker for MDD in ASD, more research is needed taking specific potential confounders, and distorting influences into account.

In this study, we have used a novel DNAzyme based approach to create a larval model of FXS in zebrafish with specific focus on the early developmental window.MethodsFmr1specific DNAzymes were electroporated into embryos to create theknockdown. Changes in RNA and protein levels of FMRP and relevant biomarkers were measured in the 0-7dpf window. Behavioral tests to measure anxiety, cognitive impairments and irritability in the larvae were conducted at the 7dpf stage. Drug treatment was carried out at various time points in the 0-7dpf window to identify the critical window for pharmacological intervention.ResultsThe DNAzyme b...

This article was first published in November 2017, ahead of Stars in Our Schools 2017. Rosie is currently campaigning for re-election in the current general election Rosie Duffield is still in shock. It never occurred to her that when she stood as a Labour candidate in the very safe Tory parliamentary seat of Canterbury earlier this year, that she might end up as an MP. The seat had never been held by Labour. But win she did. And she’s taking her new life in her stride – despite working six or seven days a week, staying up to all hours of the night to be present for votes in the House of Commons, and juggling a...

Given that many parents of children with autism seek out complementary and alternative therapies, the Canadian Paediatric Society says it's important that doctors get informed and talk about them — especially since those therapies are often expensive, unproven and even potentially harmful.

We describe the case of a 3-year-old autistic boy with undiagnosed scurvy who was scheduled for cardiac catheterization. Immediately after induction, the patient became hemodynamically unstable, which worsened with administration of nitrous oxide. Cardiac catheterization revealed pulmonary hypertension, which dramatically improved with administration of vitamin C. Anesthesiologists should be aware that scurvy is more common than previously thought, even in developed countries and can cause unexpected circulatory collapse from pulmonary hypertensive crisis.

We report here the derivation of familial iPSC lines from two controls and three ASD patients carrying NRXN1α+/−, using a non-integrating Sendai viral kit. The genotype and karyotype of the resulting iPSCs were validated by whole genome SNP array. All iPSC lines expressed comparable levels of pluripotency markers and could be differentiated into three germ layers.

ConclusionsPrevention efforts to reduce ED utilization, especially for those with ID and ASD with co-occurring psychiatric conditions, is warranted. Primary care providers and case managers should develop care plans to reduce the likelihood for emergency psychiatric utilization and ensure alternative care pathways. ED clinicians may require additional training to address the needs of this population when they present to the ED in crisis.

Successfully navigating social interactions requires the precise and balanced integration of social and environmental cues. When such flexible information integration fails, maladaptive behavioral patterns arise, including excessive aggression, empathy deficits, and social withdrawal, as seen in disorders such as conduct disorder and autism spectrum disorder. One of the main hubs for the context-dependent regulation of behavior is cingulate cortex, specifically anterior cingulate cortex (ACC) and midcingulate cortex (MCC). While volumetric abnormalities of ACC and MCC have been demonstrated in patients, little is known abo...
