Conversations about the nature of dyslexia and how dyslexia impacts reading and listening comprehension get to the heart of classification and identification models of dyslexia. Recently, this conversation has been expanded to include efforts to estimate the prevalence of dyslexia in the population through the introduction of a discrepancy index of listening comprehension and reading comprehension. This discrepancy index was proposed to serve as a proxy for dyslexia when estimating its prevalence in the population. Individuals whose reading comprehension is considerably lower than their listening comprehension are thought to exhibit unexpected reading deficits. However, the index could underrepresent certain groups within the population. The current study explored this possibility using data from a sample of 4078 public-school students. We hypothesized that students from historically marginalized or otherwise disenfranchised groups (i.e., poor and minority groups) would be less likely to have a positive listening comprehension -- reading comprehension (LC-RC) discrepancy index. Based on the results of multilevel linear mixed effect modeling, socioeconomic status (SES) contributed to differential performance on the discrepancy index when it was calculated using residual scores. Moreover, African American students were identified as having a reliably lower discrepancy index regardless of how it was calculated. It appears that this index, which only looks at the comprehension of language and not production, may, in fact, disadvantage students for whom oral language production differs from General American English (GAE). These outcomes suggest that this measure may lack the sensitivity to identify bidialectal students with dyslexia.

Translating the research base on effective reading instruction to the classroom has been a challenge. The delivery of these instructional methods requires practical skills coupled with an understanding of the aspects of language being taught. The purpose of this study was to explore the level of literacy knowledge of the English language held by educators who provide instruction to students in the primary grades. Data from 1369 classroom teachers, 74 reading interventionists, and 131 special educators comprising the analytic sample were collected as part of a training initiative in a US state. Participating educators completed a 50-item test of phonological sensitivity, phonemic awareness, decoding, encoding, and morphology. Multiple regression analyses confirmed differences in the levels of knowledge observed between the groups of educators. Reading interventionists demonstrated greater knowledge than classroom teachers and special educators in the total proportion of correct responses and across each domain. Classroom teachers demonstrated greater knowledge than special educators in phonological sensitivity and decoding but did not differ from each other in phonemic awareness, encoding, or morphology knowledge. Special educators provide intervention to students with the most severe forms of reading disabilities, yet they had the lowest level of knowledge. In contrast, reading interventionists, who provide intervention within general education, had the highest levels of knowledge. These findings suggest a need to elevate the knowledge of special educators and consider reading interventionists' role in supporting students identified with a specific learning disability in reading.

Great strides have been made in the development of effective methods of instruction for children with dyslexia. However, individual response to treatment varies, and weaknesses persist for some students with dyslexia despite otherwise effective instruction. Continued efforts are needed to support the prospective identification of poor response, particularly in routine intervention settings. The current study addressed whether indicators of dyslexia risk as outlined by hybrid diagnostic models predict response in children who received Tier 3 dyslexia intervention in their schools. The program's efficacy has been previously documented in remediating reading abilities in children with dyslexia. Data were examined from 115 elementary-age children who received routine Tier 3 dyslexia intervention in their schools. Logistic regression revealed powerful effects of preintervention fluency and gender in predicting response, with weaker effects of decoding and rapid naming. Attention-deficit/hyperactivity disorder status also played a role in predicting response. Phonological awareness and listening-reading comprehension discrepancy did not predict response. Profile analyses indicated near- and far-transfer of skill for the adequate response group, whereas growth in the poor response group was limited to near-transfer. Findings support a continuum of severity that may be associated with less robust growth and generalization over the course of the intervention.

Considerable effort has been exerted to identify effective instructional methods to teach reading in the early grades. Ideally, these practices would be provided to students by knowledgeable educators. However, many educators lack linguistic knowledge of the English language and essential concepts about early literacy acquisition that predict student reading outcomes. Furthermore, the in-service training needed to fill gaps in educator knowledge is costly and challenging to deliver at scale. Online educator training has the potential to provide a cost-effective, more readily scalable option. However, limited research has explored the efficacy of online training to increase educator knowledge of early grade reading. The current study was conducted to test the effectiveness of online training to improve educators' knowledge of early grade reading concepts. Educators (N = 86 in the analytic sample) who primarily supported students in grades K-5 were assigned randomly to one of three training conditions: waitlist control, in-person, or online. They all completed a test before and after receiving training that assessed their knowledge of early-grade reading concepts. An ANCOVA that controlled for baseline knowledge revealed that educators who received training either in-person or online had increased knowledge of early grade reading after the training relative to the waitlist control group. Furthermore, educators who received in-person training outperformed educators who received online training. This study suggests that online training provides a viable alternative to in-person in-service training and highlights a need to consider ways of enhancing the impact of online training on educator knowledge.

Resilient readers comprehend written language despite word reading deficits. The reading resiliency framework specifies candidate protective factors hypothesized to mitigate adverse effects on reading comprehension arising from phonological decoding deficiencies and, consequently, illuminates how some individuals exhibit relative reading resiliency. A focus on relative reading resiliency involves an examination of individual strengths and weaknesses because areas of relative strength can bolster one's abilities. The ability for morphological awareness and vocabulary to be strengths or protective factors contributing to reading resiliency was explored in a sample of university students. Morphological awareness is predicted to be a particularly important skill for university students due to the complexity of texts encountered in their coursework. A measure of word-level morphological awareness was positively associated with relative reading resiliency. Furthermore, across norm-referenced and standardized high-stakes testing measures of reading comprehension, vocabulary mediated the impact of morphological awareness on comprehension after controlling for phonological decoding ability. These findings suggest that morphological awareness and vocabulary skills are important contributing factors to reading comprehension and reading resilience.

A grassroots movement of parents who fear that their children's reading struggles are going unrecognized at school has led to dyslexia laws in all but three states in the U.S. The current study was undertaken to provide data relevant to this topic by characterizing the reading profiles of 71 children referred for testing at a center specializing in the assessment of reading disabilities. These children were receiving instruction and intervention in reading across the tiers of instructional support in general and special education within their schools. On average, the children demonstrated equivalent deficits in print literacy skills on norm-referenced assessments regardless of the intensity of their reading support, and the majority of children who were only receiving tier 1 instruction exhibited characteristics of dyslexia. Moreover, 69% of children only receiving tier 1 instruction, and all remaining children, performed below benchmark expectations on a curriculum-based measure of oral reading fluency. While these data are not an evaluation of the implementation of the state's dyslexia laws or the statewide implementation of RTI, they provide data characterizing the real struggles and lack of identification of children whose parents seek an external evaluation of their children's reading skills. However, they are set in the context of a state in which 66% of public-school children cannot read proficiently by the end of the third grade. The reading struggles highlighted in this clinic referral sample are unexceptional in the larger state context.

OBJECTIVE:The ultimate goal of reading is to understand written text. To accomplish this, children must first master decoding, the ability to translate printed words into sounds. Although decoding and reading comprehension are highly interdependent, some children struggle to decode but comprehend well, whereas others with good decoding skills fail to comprehend. The neural basis underlying individual differences in this discrepancy between decoding and comprehension abilities is virtually unknown. METHODS:We investigated the neural basis underlying reading discrepancy, defined as the difference between reading comprehension and decoding skills, in a three-part study: 1) The neuroanatomical basis of reading discrepancy in a cross-sectional sample of school-age children with a wide range of reading abilities (Experiment-1; n = 55); 2) Whether a discrepancy-related neural signature is present in beginning readers and predictive of future discrepancy (Experiment-2; n = 43); and 3) Whether discrepancy-related regions are part of a domain-general or a language specialized network, utilizing the 1000 Functional Connectome data and large-scale reverse inference from Neurosynth.org (Experiment-3). RESULTS:Results converged onto the left dorsolateral prefrontal cortex (DLPFC), as related to having discrepantly higher reading comprehension relative to decoding ability. Increased gray matter volume (GMV) was associated with greater discrepancy (Experiment-1). Region-of-interest (ROI) analyses based on the left DLPFC cluster identified in Experiment-1 revealed that regional GMV within this ROI in beginning readers predicted discrepancy three years later (Experiment-2). This region was associated with the fronto-parietal network that is considered fundamental for working memory and cognitive control (Experiment-3). INTERPRETATION:Processes related to the prefrontal cortex might be linked to reading discrepancy. The findings may be important for understanding cognitive resilience, which we operationalize as those individuals with greater higher-order reading skills such as reading comprehension compared to lower-order reading skills such as decoding skills. Our study provides insights into reading development, existing theories of reading, and cognitive processes that are potentially significant to a wide range of reading disorders.

All but seven U.S. states have laws that govern some aspects of dyslexia screening, intervention, or teacher training in public schools. However, in the three states that mandate child-level reporting, data indicate lower than expected rates of dyslexia identification when compared with commonly accepted dyslexia prevalence rates. To better understand this apparent mismatch, this study explores factors that might predict the school-assigned identification of individuals with dyslexia. Deidentified data on 7,947 second-grade students in 126 schools from one U.S. state included a universal screening measure of literacy skills indicative of dyslexia (i.e., reading and spelling), school-assigned dyslexia classification, and demographic characteristics. As expected, behavioral characteristics of dyslexia from universal screening were associated with school-assigned dyslexia classification. However, dyslexia classification was less likely for minority students and individuals attending schools with a higher percentage of minority students. Students who showed behavioral characteristics of dyslexia and attended schools with a higher proportion of other students with similar poor literacy skills were more likely not to receive a school-assigned dyslexia classification. The findings suggest systematic demographic differences in whether a student is identified with dyslexia by schools even when using universal screening.

Recent research in political science has uncovered and theorized about inequalities within the field. In this article, we explore a lesser publicly discussed difference that likely affects the research process: start-up funding. We surveyed assistant professors in US political science departments about their start-up packages, and we find that characteristics of the institution, prestige of the researcher's PhD alma mater, and having competing offers predict receiving a start-up fund at all and receiving more research money in that start-up fund. The evidence also suggests that women's offers are more sensitive to alma mater prestige, with women from the least prestigious alma maters receiving less funding than men from similarly ranked schools. Notably, publishing more does not seem to help women or men, suggesting that women from low-prestige departments in particular cannot work their way out of this disadvantage. [ABSTRACT FROM AUTHOR]

This study examined whether variations in brain development between kindergarten and Grade 3 predicted individual differences in reading ability at Grade 3. Structural MRI measurements indicated that increases in the volume of two left temporo-parietal white matter clusters are unique predictors of reading outcomes above and beyond family history, socioeconomic status, and cognitive and preliteracy measures at baseline. Using diffusion MRI, we identified the left arcuate fasciculus and superior corona radiata as key fibers within the two clusters. Bias-free regression analyses using regions of interest from prior literature revealed that volume changes in temporo-parietal white matter, together with preliteracy measures, predicted 56% of the variance in reading outcomes. Our findings demonstrate the important contribution of developmental differences in areas of left dorsal white matter, often implicated in phonological processing, as a sensitive early biomarker for later reading abilities, and by extension, reading difficulties.

An increasing number of U.S. sheriffs claim that they will not enforce gun safety policies from state and federal governments in their counties. As locally elected law enforcement with a unique institutional position and significant powers, sheriffs play a key role in local policy implementation. To better understand cooperation (or the lack thereof) between levels of government, we look at these sheriffs' contentious relationships over firearm regulation. We argue that sheriffs mobilized to resist state and federal gun safety policies through right-wing extremist efforts, tracing the involvement of sheriffs in gun policy over time. Using two surveys of sheriffs (conducted in 2012 and 2021), we show that sheriffs' preferences against gun safety measures relate to right-wing extremist attitudes, even with controls for political and demographic factors. We demonstrate relationships between sheriffs' right-wing extremism and an expressed reluctance to support or enforce a wide set of gun safety policies. [ABSTRACT FROM AUTHOR]

Diffusion Tensor Imaging (DTI) was used to investigate the relationship between white matter and reading abilities in reading impaired and non-reading impaired children. Seventeen children (7 non-reading impaired, 10 reading impaired) participated in this study. DTI was performed with 2 mm isotropic resolution to cover the entire brain along 30 noncollinear directions. Voxelwise analyses were conducted on data processed through Tract Based Spatial Statistics (TBSS). The data replicated previous results seen across multiple studies and extended findings to include measures of both real word and pseudoword decoding. Negative correlations were observed in the left posterior corpus callosum between fractional anisotropy (FA) values and both measures of decoding. Positive correlations between FA values and real word and pseudoword decoding were observed in the left superior corona radiata. This extension of findings regarding correlations between the corona radiata and reading skills suggests an important direction for future research into the neurological substrates of reading.

Start-up packages vary enormously, particularly across institutions, and not all faculty know what items they may negotiate for to support their probationary period. To demystify this part of the hidden curriculum, we discuss the components of start-up packages and other benefits that may be provided to new faculty at the time of hire. We focus on five broad topics: compensation and personal support, general support, research support, teaching support, and service and professional development. Drawing on the results of a survey of tenure-track assistant political science professors in the United States, we also provide an overview of the prevalence of a variety of items at different types of institutions and discuss other considerations in the negotiation process to close the knowledge gap for candidates during negotiations.
