#1
Sarah E Berger, Regina T Harbourne, Melissa N Horger
This chapter discusses what cognition-action trade-offs in infancy reveal about the organization and developmental trajectory of attention. We focus on internal attention because this aspect is most relevant to the immediate concerns of infancy, such as fluctuating levels of expertise, balancing multiple taxing skills simultaneously, learning how to control attention under variable conditions, and coordinating distinct psychological domains. Cognition-action trade-offs observed across the life span include perseveration during skill emergence, errors and inefficient strategies during decision making, and the allocation of resources when attention is taxed...

BACKGROUND: Medical school and residency training in ophthalmoscopic evaluation is limited, reducing diagnostic accuracy. We sought to evaluate the efficacy of self-study using an ophthalmoscopy simulator to improve the technical motor skills involved in direct funduscopy in postgraduate pediatric residents. METHODS: In this randomized-controlled study, 17 pediatric residents (postgraduate years 1-3) were randomized to control (n=8) or intervention (n=9) groups...

Fidgeting, defined as the generation of small movements through nervousness or impatience, is one of cardinal characteristic of ADHD. While fidgeting is, by definition, a motor experience still nothing is known about the effects of fidgeting on motor control. Some forms of fidgeting involve also the manipulation of external objects which, through repetition, may become automatic and second nature. Both repetition and practice are important for the acquisition of motor skills and, therefore, it is plausible that the repetitive manipulation of objects may influence motor control and performance...

For many degenerative cerebellar diseases, currently, no effective treatment that would substantially restore cerebellar functions is available. Neurotransplantation could be a promising therapy for such cases. Nevertheless, there are still severe limitations for routine clinical use. The aim of the work was to assess volume and morphology and functional impact on motor skills of an embryonic cerebellar graft injected in the form of cell suspension in Lurcher mutant and wild-type mice of the B6CBA and C3H strains after a 6-month survival period...

BACKGROUND: Ehler-Danlos syndome (EDS) refers to a group of heritable connective tissue disorders; rare manifestations of which are cervical kyphosis and clinical myelopathy. Surgical treatment is described for the deformity in the thoracolumbar spine in adolescents but not for infantile cervical spine. Internal fixation for deformity correction in the infantile cervical spine is challenging due to the diminutive size of the bony anatomy and the lack of spinal instrumentation specifically designed for young children...

A thorough understanding of the cognitive effects of antidepressant medications is essential given their frequency of use. This meta-analysis was conducted to investigate whether antidepressants differentially affect the various domains of cognitive functioning for depressed and non-depressed participants. An electronic search of PsycInfo, Medline and Google Scholar was conducted for all journal articles published between January 1998 and January 2017. Thirty-three studies were included enabling calculation of Hedges' g using a random effects model for the cognitive domains of divided attention, executive function, expressive language, immediate memory, perceptual motor skills, processing speed, recent memory, sustained attention, visuospatial-constructional skills and working memory...

Recurrent deletions of a ~600-kb region of 16p11.2 have been associated with a highly penetrant form of childhood apraxia of speech (CAS). Yet prior findings have been based on a small, potentially biased sample using retrospectively collected data. We examine the prevalence of CAS in a larger cohort of individuals with 16p11.2 deletion using a prospectively designed assessment battery. The broader speech and language phenotype associated with carrying this deletion was also examined. 55 participants with 16p11...

BACKGROUND: Nusinersen is an antisense oligonucleotide drug that modulates pre-messenger RNA splicing of the survival motor neuron 2 ( SMN2) gene. It has been developed for the treatment of spinal muscular atrophy (SMA). METHODS: We conducted a multicenter, double-blind, sham-controlled, phase 3 trial of nusinersen in 126 children with SMA who had symptom onset after 6 months of age. The children were randomly assigned, in a 2:1 ratio, to undergo intrathecal administration of nusinersen at a dose of 12 mg (nusinersen group) or a sham procedure (control group) on days 1, 29, 85, and 274...

Vision plays an important role in the development of communication, social interaction, spatial awareness, and the motor skills needed to explore the environment. In the past 2 years, researchers have described the broad spectrum of clinical features that comprise congenital Zika syndrome (CZS). The ocular manifestations are considered 1 important pillar of this new entity. The most characteristic ophthalmic findings include chorioretinal scars and focal pigmentary changes seen in the macular region. Since these findings were first reported, other researchers have validated and extended them, leading to a more complete picture of the spectrum of ocular manifestations related to CZS...

In individuals with autism spectrum disorder (ASD), de novo mutations have previously been shown to be significantly correlated with lower IQ but not with the core characteristics of ASD: deficits in social communication and interaction and restricted interests and repetitive patterns of behavior. We extend these findings by demonstrating in the Simons Simplex Collection that damaging de novo mutations in ASD individuals are also significantly and convincingly correlated with measures of impaired motor skills...

Introduction Neurodevelopmental abnormalities are common in children with CHD and are the highest-priority concerns for parents and professionals following cardiac surgery in childhood. There is no additional routine monitoring of development for children with CHD in the United Kingdom; hence, neurodevelopmental concerns may be detected late, precluding early referral and intervention. METHODS: An early recognition tool - the "Brief Developmental Assessment" - was developed using quality improvement methodology involving several iterations and rounds of pilot testing...

INTRODUCTION: Two-wheel bike riding can be a goal for children with cerebral palsy (CP) and a means of participating in physical activity. It is possible for some children with CP to ride a two-wheel bike; however, currently far fewer can ride compared with their typically developing peers. Evidence supports training targeted towards goals of the child with CP and their family; yet there is little evidence to guide best-practice bike skills training. Task-specific training may lead to attainment of two-wheel bike-specific goals...

OBJECTIVES: The aim of the presented study is to provide age- and gender-related normative values and MQ values for a motor skills test, the Athletic Skills Track, among 4- to 12-year-old children. DESIGN: Cross-sectional. METHODS: In 2016, a total of 7977 Dutch children, 4036 boys (mean age 8.6 years, SD 2.1) and 3941 girls (mean age 8.6 years, SD 2.1), performed an age-related version of the Athletic Skills Track (AST). The AST is a track consisting of 5-7 fundamental movement skill tasks that should be completed as fast as possible...

Eye-tracking research has revealed that, compared to novices, experts make longer ocular fixations on the target of an action when performing motor skills; that is, they have a longer quiet eye. Remarkably, the reason why a longer quiet eye aids movement has yet to be established. There is a need for interdisciplinary research and new measures to accelerate progress on the mechanistic understanding of the phenomenon. With the aim to provide researchers with new tools, we assessed the utility of electrooculography (EOG) to examine ocular activity while 10 experts and 10 novices putted golf balls...

Motor skills are interrelated with essential domains of childhood such as cognitive and social development. Thus, the evaluation of motor skills and the identification of atypical or delayed motor development is crucial in pediatric practice (e.g., during well-child visits). Parental reports on motor skills may serve as possible indicators to decide whether further assessment of a child is necessary or not. We compared parental reports on fundamental motor skills performance level (e.g., hopping, throwing), based on questions frequently asked in pediatric practice, with a standardized motor test in 389 children (46...
