This study examined the associations between the frequency of low scores on the Immediate Post-Concussion Assessment and Cognitive Test (ImPACT) by race and socioeconomic status (SES), using the proxy of Title I school status, among adolescent student-athletes and calculated multivariate base rates. There were 753 participants assigned to groups based on race (White: n = 430, 59.8%; Black: n = 289, 40.2%) and SES. Black student-athletes obtained more low neurocognitive test scores, which was associated with lower SES. The current study offers a resource to clinicians involved in concussion management who may wish to consider race and SES when interpreting ImPACT test performances.

This study measured mu rhythm desynchronization (MRD), while nine-month-old infants observed an agent extend her arm and hand, palm up ('back-of-hand action') either in social (object and recipient present), individual (object present, recipient absent), or social object-absent (recipient present, object absent) situations across two experiments. In addition, infants' MRD was measured as they reached for objects. Results revealed significant mu desynchronization in the right centro-parietal region selectively for the social group, indicating that infants processed the back-of-hand action as an object-directed request. Findings suggest to extend the action reconstruction account to object-directed communicative actions as well.

Objective: To examine associations between sleep-disordered breathing (SDB) and executive/attentional function in pediatric sickle cell disease (SCD).

Methods: Sixty youth with SCD ages 8-18 years and caregivers completed the Pediatric Sleep Questionnaire (PSQ), Delis Kaplan Executive Function System Trail Making Test (DKEFS TMT), Psychomotor Vigilance Test (PVT), and the Behavior Rating Inventory Of Executive Function, Second Edition (BRIEF-2) Parent Report.

Results: The PSQ significantly predicted the BRIEF-2 Parent Report, F(1, 58) = 44.64, p < .001, R² = 0.44, f² = 0.77.

Conclusions: Sleep-disordered breathing symptoms may predict informant-rated executive dysfunction in pediatric SCD, but not performance-based executive function.

This research was funded through the American Speech and Hearing Foundation's 2012 StudentResearch Grant in Early Childhood Language Development awarded to Vanessa Harwood as well as an anonymous generous donation to Haskins Laboratories. Electrophysiological measures of language within early childhood provide important information about neurolinguistic development. We investigated associations between amplitude and latency of the P1 and N2 event-related potential components in response to spoken pseudowords, and clinical measures of language performance within a sample of 58 typically developing children between 24 and 48 months. N2 amplitude differences between repeated and new tokens were correlated with measures of expressive and receptive language and speech sound production. Phonemic sensitivity measured by the N2 component may reflect the integrity of neural networks that are important for speech perception and production in young children.

The current study utilized a large, unselected sample of adolescent twins to examine whether processing speed (PS) is an important shared predictor that accounts for covariance among reading, math, ADHD, and rapid naming (RN). The best fitting model included correlated but distinguishable latent measures of PS, RN, reading, math, inattention, hyperactivity/impulsivity, and academic fluency. PS was a shared predictor across all outcomes, while RN was uniquely associated with reading, fluency, and (albeit weakly) math. The results add to a growing literature suggesting that PS and RN may be important components of comprehensive neuropsychological models of academics, ADHD, and their covariation.

Dyslexia is a neurodevelopmental difficulty affecting reading, but recent data in adults suggest that difficulties also extend to face processing. Here, we tested face processing in school children with and without dyslexia, using eye-tracking and neuropsychological tests. Children with dyslexia didn't differ significantly from controls in face gaze patterns, face memory, or face identification accuracy. However, they were slower and more heterogeneous, with larger within-group variance than controls. Increased gaze patterns toward the eyes were associated with better face memory in controls. We discuss the possible role of experiential factors in prior research linking dyslexia and face processing differences.

Children with congenital heart disease (CHD) are at increased risk for neurodevelopmental delays. This study of school-aged children with single ventricle CHD compared access to services for those who did and did not complete an evaluation. Children completing an evaluation had more academic services, including an Individualized Education Plan (66% vs 34%,P = .017), small group academic instruction (54% vs 20%,P = .01), any instructional supports (77% vs 44%,P = .008). A barrier to not completing the evaluation was lack of knowledge about the Cardiac Neurodevelopmental Program (82%). The neurodevelopmental evaluation is an impactful tool that can increase access to school services in vulnerable CHD patients.
