Orthographic systems vary dramatically in the extent to which they encode a language's phonological and lexico-semantic structure. Studies of the effects of orthographic transparency suggest that such variation is likely to have major implications for how the reading system operates. However, such studies have been unable to examine in isolation the contributory effect of transparency on reading because of covarying linguistic or sociocultural factors. We first investigated the phonological properties of languages using the range of the world's orthographic systems (alphabetic, alphasyllabic, consonantal, syllabic, and logographic), and found that, once geographical proximity is taken into account, phonological properties do not relate to orthographic system. We then explored the processing implications of orthographic variation by training a connectionist implementation of the triangle model of reading on the range of orthographic systems while controlling for phonological and semantic structure. We show that the triangle model is effective as a universal model of reading, able to replicate key behavioral and neuroscientific results. The model also generates new predictions deriving from an explicit description of the effects of orthographic transparency on how reading is realized and defines the consequences of orthographic systems on reading processes.

The human visual system incorporates several solutions to this challenge, 1 of which is a reflexive covert attention system that is rapidly responsive to both the physical salience and the task-relevance of new information. This article presents a model that simulates behavioral and neural correlates of reflexive attention as the product of brief neural attractor states that are formed across the visual hierarchy when attention is engaged. Such attractors emerge from an attentional gradient distributed over a population of topographically organized neurons and serve to focus processing at 1 or more locations in the visual field, while inhibiting the processing of lower priority information. The model moves toward a resolution of key debates about the nature of reflexive attention, such as whether it is parallel or serial, and whether suppression effects are distributed in a spatial surround, or selectively at the location of distractors. The model also develops a framework for understanding the neural mechanisms of visual attention as a spatiotopic decision process within a hierarchy and links them to observable correlates such as accuracy, reaction time (RT), and the N2pc and PD components of the electroencephalogram (EEG). This last contribution is the most crucial for repairing the disconnect that exists between our understanding of behavioral and neural correlates of attention.

Yet, it is unclear how comprehension of the words that capture spatial relations, words like behind and under, might be associated with children's early spatial and mathematics skills. The current study addressed this question by conducting a moderated mediation model to test the potential moderating effects of group factors, such as socioeconomic status (SES) and gender, on the possible mediation of spatial language comprehension on the association between spatial skill and mathematics performance. In total, 192 3-year-olds were tested on a battery of assessments, including a novel Spatial Language Comprehension Task, a test of spatial skills (2- and 3-dimensional trials of the Test of Spatial Assembly [2D and 3D TOSA, respectively]), and a composite of 2 mathematical assessments. The results indicate that this novel Spatial Language Comprehension Task is a reliable measure useful for examining group differences and the early space-math link. Specifically, higher-SES preschoolers and females had higher spatial language comprehension compared with their lower-SES peers and males, respectively. These SES and gender disparities in spatial language comprehension are concerning, given the strong association between spatial language comprehension and mathematics skills. Additionally, spatial language comprehension mediated the association between spatial skill and mathematics performance for females only. Future work should examine the potential causal role that spatial language comprehension may have in concurrent and later spatial and mathematics skills.

Many studies have demonstrated atypical responses to audiovisual sensory inputs, particularly those containing sociolinguistic information. It is currently unclear whether these atypical responses are due to the linguistic nature of the inputs or the social aspect itself. Further, it is unclear how atypical sensory responses to sociocommunicative stimuli intersect with autism symptomatology. The current study addressed these outstanding questions by using pupillometry in mental age-matched children with and without autism (N = 71) to examine physiological responses to dynamic, audiovisual stimuli including social, sociolinguistic, socioemotional, and nonsocial stimuli, as well as to temporally manipulated stimuli. Data revealed group differences in pupillary responses with social stimuli but not nonsocial stimuli and, importantly, showed no variation through the inclusion of linguistic or emotional information. This suggests that atypical sensory responses are driven primarily by the inclusion of social information broadly. Further, individual responses to social stimuli were significantly correlated with a wide range of autism spectrum disorder symptomatology, including social communication, restricted interests and repetitive behaviors, and sensory processing issues. Pupillary responses to social but not nonsocial presentation were also capable of predicting diagnosis with a high level of selectivity, but only with marginal sensitivity. Finally, responses to the temporal manipulation did not yield any group differences, suggesting that while atypical multisensory temporal processing has been well documented in autism at the level of behavior and perception, these issues may be intact at the physiological level.

Integrating the identity engagement model (Cohen, Purdie-Vaughns, & Garcia, 2012) with the process model of stereotype threat (Schmader, Johns, & Forbes, 2008), we categorized STIs into 3 types belief-based, identity-based, and resilience-based STIs. Combining 251 effect sizes from 181 experiments, we found an overall effect size of d = 0.44, with the intervention group outperforming the control group. Subgroup analyses showed that although all 3 types of STIs helped counter stereotype threat, primary-appraisal-based (i.e., belief-based and identity-based) STIs were more effective than secondary-appraisal-based (i.e., resilience-based) STIs. We also traced the theoretical roots of 11 specific intervention strategies and showed that 9 of them yielded significant effect sizes. Moreover, we found evidence of publication bias regarding some but not all intervention types. These findings' theoretical and practical implications, as well as methodological issues and future research directions for the STI literature, are discussed.

At the same time, it isn't clear that investigators and reviewers prioritize psychometric soundness to a degree that would allow one to have sufficient confidence in conclusions regarding constructs. The purposes of the present article are to (a) examine current scale development and evaluation practices in JAP; (b) compare these practices to recommended practices, previous practices, and practices in other journals; and (c) use these comparisons to make recommendations for reviewers, editors, and investigators regarding the creation and evaluation of measures including Excel-based calculators for various indices. Finally, given that model complexity appears to have increased the need for short scales, we offer a user-friendly R Shiny app (https//orgscience.uncc.edu/about-us/resources) that identifies the subset of items that maximize a variety of psychometric criteria rather than merely maximizing alpha.

The Indonesia Basic Health Research 2018 indicates that Indonesian children are still among the shortest in the world. When referred to World Health Organization Child Growth Standards (WHOCGS), the prevalence of stunting reaches up to 43% in several Indonesian districts. Indonesian National Growth Reference Charts (INGRC) were established in order to better distinguish between healthy short children and children with growth disorders. We analyzed height and weight measurements of healthy Indonesian children using INGRC and WHOCGS.
6972 boys and 5800 girls (n=12,772), aged 0-59 months old, from Bandung District were measured. Z-scores of length/height and body mass index were calculated based on INGRC and WHOCGS.
Under 5-year-old Indonesian children raised in Bandung are short and slim. Crizotinib mw Mean height z-scores of boys is -2.03 [standard deviation (SD) 1.31], mean height z-scores of girls is -2.03 (SD 1.31) when referred to WHOCGS indicating that over 50% of these children are stunted. Bandung children are stead applying INGRC that closely mirror height and weight increments in Bandung children. INGRC appear superior for practical and clinical purposes, such as detecting growth and developmental disorders.
Acute lymphoblastic leukemia (ALL), is a biologically heterogeneous disease where diagnosis, treatment and prognosis is heavily dependent on the correct characterization of the immunophenotype of each case.
To describe the immunophenotypic and laboratory features of a cohort of Sri Lankan children and adults with ALL and to compare them with those reported in other series.
Records of 229 patients who were suspected of having acute leukaemia and referred for flow cytometry to the Asiri Hospital Sri Lanka, between August 2009 and October 2013 were reviewed. Referrals were from across the country including the National Cancer Institute.
Sixty seven percent were children below 12 years of age. 80% had B-lymphoblastic leukaemia (B-ALL), 20% T- lymphoblastic leukaemia (T-ALL). In children, the peak age of diagnosis was between 2-6 years in B-ALL (61%) and 3-6 years (43.7%) in T-ALL. Incidence was commoner in males in all age groups and subtypes except in the adult B ALL group where the incidence was equal. Ninety three percent of paediatric B-ALL and 67% adult B-ALL were CD10 positive common ALL.
