Sleep deprivation adversely affects the ability to perform cognitive tasks, but theories range from predicting an overall decline in cognitive functioning because of reduced stability in attentional networks to specific deficits in various cognitive domains or processes. We measured the effects of sleep deprivation on two memory tasks, item…

Individual differences in motivational beliefs, such as writing efficacy and attitudes toward writing in different contexts (academic, recreational, print or digital), are hypothesised to account for variability in writing performance. This study tested this proposition with 185 middle school students (58% were male), examining if writing…

Response to intervention (RTI) has been promoted for nearly 20 years as a valid supplement to or alternative method of learning disability (LD) identification. Nevertheless, important unresolved questions remain about its role in disability identification. We had two purposes when conducting this study of 229 economically and racially diverse poor…

This paper reports some experiments on probabilistic reasoning designed to investigate the impact of the probabilistic problem presentation format (verbal-numerical and graphical-pictorial) on subjects' confidence in the correctness of their performance, other than the calibration between confidence and accuracy. To understand the potential effect…

Reading Thai and English is an essential skill for students in rural areas. This R&D research studies three levels of reading enhancement of upper elementary, junior high school, and vocational certificate students in rural areas of Nakhon Phanom. The sample group consisted of 108 students. Quantitative and qualitative research methods were…

This paper reports findings from a project called "The National Panel of Raters" (NPR) that took place within a writing test programme in Norway (2010-2016). A recent research project found individual differences between the raters in the NPR. This paper reports results from an explorative follow up-study where 63 NPR members were…

First-year architecture students are expected to utilise visuospatial abilities to generate/construct, retain, rotate and manipulate space mentally and physically through physical and digital representations. This study of 57 female and 23 male participants was conducted to investigate first-year architecture students' visuospatial abilities by…

The role played by working memory (WM), that is, the capacity to temporarily maintain and cognitively process information, has been extensively studied in second language (L2) research. In a general sense, WM has been shown to be related to various aspects of L2 learning and use; however, little information is available regarding its relationship…

The Predict-Observe-Explain (POE) learning cycle improves understanding of the connection between empirical results and theoretical concepts when students engage in hands-on experimentation. This study explored whether training students to use a POE strategy when learning from social science texts that describe theories and experimental results…

We investigated the contributions of multiple strands of factors--individual characteristics (struggling reader status, working memory, vocabulary, grammatical knowledge, knowledge-based inference, theory of mind, comprehension monitoring), a text feature (narrative vs. expository genre), and question types (literal and inferential)--to one's…

Education decision makers in Colorado, Missouri, and South Dakota share concerns about and need more information on changes in school and district leadership (principals, assistant principals, superintendents, and assistant superintendents), including mobility (when leaders move to a different school or district within the state public school…

Education decision makers in Colorado, Missouri, and South Dakota share concerns about and need more information on changes in school and district leadership (principals, assistant principals, superintendents, and assistant superintendents), including mobility (when leaders move to a different school or district within the state public school…

Education decision makers in Colorado, Missouri, and South Dakota share concerns about mobility and attrition among school and district leaders. In collaboration with educators in these states, the Regional Educational Laboratory Central used administrative data to examine the percentages of school and district leaders who remained in a leadership…

An enduring challenge in visual-spatial research has been to identify the factors contributing to individual differences in ability. This research investigated the overall, verbal, and nonverbal visual-spatial ability of 61 (34 boys) three- to five-year-olds (M[subscript age] = 57.3 months; SD = 7.9) and the following factors known to be related…

Narrative production draws upon linguistic, cognitive and pragmatic skills, and is subject to substantial individual differences. This study aimed to characterise the development of narrative production in late childhood and to assess whether children's cumulative experience of reading fiction is associated with individual differences in narrative…
