The frequency of occurrence of words and sounds has a pervasive influence on typically developing children's language acquisition. For instance, highly frequent words appear earliest in a child's lexicon, and highly frequent phonemes are produced more accurately. This study evaluates (a) whether word frequency influences word accuracy and (b)…

A case-control study was performed to determine whether an association exists between exposure to synthetic oxytocin and a subsequent autism spectrum disorder diagnosis; 171 children under age 18 meeting "Diagnostic and Statistical Manual of Mental Disorders" (5th ed.) autism spectrum disorder criteria were compared to 171 children…

Purpose: Our objective was to delineate components of motor performance in specific language impairment (SLI); specifically, whether deficits in timing precision in one effector (unimanual tapping) and in two effectors (bimanual clapping) are observed in young children with SLI. Method: Twenty-seven 4- to 5-year-old children with SLI and 21…

The aim of this study was to describe clinical features of PBD comorbidity in children with ASD. Forty children with ASD and PBD aged 6-18 years, and 40 age- and sex-matched ASD subjects with no affective episodes were included in the study. Autism Behavior CheckList, Abberant Behavior CheckList, and Young Mania Rating Scale-Parent Version were…

Background: This study compared levels of physical activity completed by adults with and without Down syndrome. Method: Fifteen adults with and 15 adults without Down syndrome matched for age and gender, took part. The intensity and duration of physical activity were measured using RT3 accelerometers worn for seven days. Results: Only, 12…

Purpose: The importance of early intervention for fostering language in children with hearing loss has been well documented; those that facilitate parent engagement are particularly effective. Listening and spoken language outcomes among children with hearing loss continue to fall short compared to hearing peers, despite improvements in hearing…

Objective: This study evaluated the mental health characteristics and beliefs of student service members/veterans (SSM/Vs) who have been exposed to another's death by suicide. Participants: A total of 39 SSM/Vs exposed to suicide and 32 SSM/Vs not exposed to suicide were sampled from a larger, epidemiological survey. An age- and gender-matched…

Atypical learning and memory in early life can promote atypical behaviors in later life. Less relational learning and inflexible retrieval in childhood may enhance restricted and repeated behaviors in patients with autism spectrum disorder. The purpose of this study was to elucidate the mechanisms of atypical memory in children with autism…

To identify quantitative indicators of social communication dysfunctions, we explored the oculomotor performances in subjects with autism spectrum disorders. Discordant findings in the literature have been reported for oculomotor behavior in subjects with autism spectrum disorders. This study aimed to explore reflexive and voluntary saccadic…

This study investigates the implicit sequence learning abilities of dyslexic children using an artificial grammar learning task with an extended exposure period. Twenty children with developmental dyslexia participated in the study and were matched with two control groups--one matched for age and other for reading skills. During 3 days, all…

Purpose: This study examined the influence of cognitive factors on spoken word recognition in children with developmental language disorder (DLD) and typically developing (TD) children. Method: Participants included 234 children (aged 7;0-11;11 years;months), 117 with DLD and 117 TD children, propensity matched for age, gender, socioeconomic…

Purpose: We aimed to study narrative skills in Mandarin-speaking children with language impairment (LI) to compare with children with LI speaking Indo-European languages. Method: Eighteen Mandarin-speaking children with LI (mean age 6;2 [years;months]) and 18 typically developing (TD) age controls told 3 stories elicited using the Mandarin…

Purpose: This study examines the contribution of number morphology to language comprehension abilities among children with specific language impairment (SLI) and age-matched controls. It addresses the question of whether number agreement facilitates the comprehension accuracy of object-initial declarative sentences. According to the predictions of…

Background: Adventure experiences offer opportunities to improve resilience by exposure to controlled challenging situations. While previous studies have shown improvements in resilience, they have often lacked matched control groups, relied on a single measure of resilience, and had limited longitudinal follow-up. Purpose: This research assessed…

This study uses data from the Early Childhood Longitudinal Study, 2010-2011 to better understand the rates of grade retention during elementary school and the factors associated with this grade retention. Using matched student-teacher and student-principal data, I examine the student-, teacher-, and school-level factors associated with a student's…
