Background: The purpose of this study was to examine the relationship between selective visual attention (SVA), reading decoding, listening comprehension, and reading comprehension in children with and without a reading disorder.Methods: We used longitudinal data from the Avon Longitudinal Study of Parents and Children (ALSPAC). We split children into four groups: Typical Readers, Dyslexics, Poor Comprehenders, and Comorbid Reading Disorder. We included measures of single word reading, nonword reading, spelling, phonological processing, vocabulary, receptive language, nonverbal intelligence, selective attention, and reading comprehension. We used ANOVA, correlations, and structural equation modeling (SEM) to examine the relationship between SVA and reading. We fit two possible models: SVA Indirect and SVA Direct. The difference between these models was the inclusion of a direct path from SVA to reading comprehension.Results: We examined an indirect model, where SVA predicted reading comprehension through word decoding and listening comprehension, and a direct model, which included a pathway from SVA to reading comprehension. Based on our ANOVA and correlation results, we collapsed the Dyslexic, Poor Comprehenders, and Comorbid Reading Disorder Groups for the SEM. We found evidence that for Typical Readers, an indirect model was the best fit, whereas the direct model was the best model for children with a reading disorder.Conclusions: Selective visual attention is related to reading comprehension. This relationship differs for children with and without a reading disorder.

Poor literacy rates contribute to low school performance for children across America. In particular, low-income schools continue to struggle with declining literacy rates. Issues with literacy are often attributed to lack of reading comprehension. This study tested the effects of choice on reading comprehension in second- and third-grade students at a high-income school and a low-income school. Students were observed while reading silently and aloud to see if either method affected reading comprehension. Data were collected from 32 students before, during, and after reading to determine whether students’ comprehension levels were higher when given opportunities to choose their own books or when they read assigned books. Trials were performed while students read silently and then aloud. Results indicated that students had higher comprehension levels both when they could choose their own books and when they read silently.

AbstractSleep is vital for survival. Yet, under environmentally challenging conditions such as starvation, animals suppress their need for sleep. Interestingly, starvation-induced sleep loss does not evoke a subsequent sleep rebound. Little is known about how starvation-induced sleep deprivation differs from other types of sleep loss, or why some sleep functions become dispensable during starvation. Here we demonstrate that downregulation of unpaired-2 (upd2, the Drosophila ortholog of leptin), is sufficient to mimic a starved-like state in flies. We use this ‘genetically starved’ state to investigate the consequences of a starvation signal on visual attention and sleep in otherwise well-fed flies, thereby sidestepping the negative side-effects of undernourishment. We find that knockdown of upd2 in the fat body is sufficient to suppress sleep while also increasing selective visual attention and promoting night-time feeding. Further, we show that this peripheral signal is integrated in the fly brain via insulin-expressing cells. Together, these findings identify a role for peripheral tissue-to-brain interactions in the simultaneous regulation of sleep and attention, to potentially promote adaptive behaviors necessary for survival in hungry animals.Author SummarySleep is important for maintaining both physiological (e.g., metabolic, immunological, and developmental) and cognitive processes, such as selective attention. Under nutritionally impoverished conditions, animals suppress sleep and increase foraging to locate food. Yet it is currently unknown how an animal is able to maintain well-tuned cognitive processes, despite being sleep deprived. Here we investigate this question by studying flies that have been genetically engineered to lack a satiety signal, and find that signaling from fat bodies in the periphery to insulin-expressing cells in the brain simultaneously regulates sleep need and attention-like processes.
