Individual differences in cognitive performance depend on age, skill, and type of task. Nonetheless, whether performance is measured with accuracy (ACC) or with the trade-off between responding speed and accuracy (SAT) could render subtle different relationships. Age and skill might associate more strongly with SAT performance in reasoning tasks,…

This study examines the relation between K-12 teachers' trust in artificial intelligence (TAI), their knowledge of AI (KAI), and their digital competence (DC). It further examines the relation between TAI and age, sex, teaching experience and International Standard Classification of Education (ISCED) levels. The study employed a comprehensive and…

The mental health of women in the perinatal period is the focus of attention around the world. Many studies emphasize the problems that women experience during pregnancy or after childbirth, also focusing on mental health problems. In this context, the attention towards the woman, both during pregnancy and after birth, should be very great,…

We examined the development of numerical magnitude representations of fractions and decimals from fourth to 12th grade. In Experiment 1, we assessed the rational number magnitude knowledge of 200 Chinese fourth, fifth, sixth, eighth, and 12th graders (92 girls and 108 boys) by presenting fraction and decimal magnitude comparison tasks as well as…

We constructed and calibrated an instrument targeting conceptual and procedural fraction knowledge. We used this instrument in a quantitative study with 126 secondary students (7th and 9th graders), testing the hypothesis that there are individual differences in the way students combine the two types of knowledge. Cluster analysis revealed four…

Researchers have identified sources of individual differences in writing across beginning and developing writers. The aim of the present study was to further clarify the sources of this variability by investigating the extent to which there are differences in genetic and environmental factors underlying the associations between lexical diversity,…

We examined developmental and individual differences in 6th and 8th graders' fraction arithmetic and overall mathematics achievement and related them to differences in understanding of fraction magnitudes, whole number division, executive functioning, and metacognitive judgments within a crosssectional design. Results indicated that the difference…

Several judgment and decision-making tasks are assumed to involve memory functions, but significant knowledge gaps on the memory processes underlying these tasks remain. In a study on 568 adults between 25 and 80 years of age, hypotheses were tested on the specific relationships between individual differences in working memory, episodic memory,…

We examined developmental and individual differences in 6th and 8th graders' fraction arithmetic and overall mathematics achievement and related them to differences in understanding of fraction magnitudes, whole number division, executive functioning, and metacognitive judgments within a cross-sectional design. Results indicated that the…

In this review of literature we examine empirical research of individual differences in younger readers' knowledge and use of expository text structures. The goal of this review is to explore the influence of reader and text characteristics in order to better understand the instructional needs of elementary school readers. First we review research…

The aims of this research were to examine the development of teaching skills in preschool children and to explore the relation between teaching and theory of mind (ToM). After learning a new board game, 3.5-, 4.5-, and 5.5-year-old children (N = 46) were asked to teach a confederate who "doesn't know how to play the game." They also received two…

Interview results indicated terminally ill patients with knowledge produced significantly longer transcripts than others. Groups did not differ significantly on state or trait anxiety scales. There were significant associations involving age, anxiety, and the dependent variables of the content analysis, especially among terminally ill patients…

Domain knowledge facilitates performance in many cognitive tasks. However, very little is known about the interplay between domain knowledge and factors that are believed to reflect general, and relatively stable, characteristics of the individual. The primary goal of this study was to investigate the interplay between domain knowledge and one…

The representational abilities of 24 preschool children were investigated in relation to their ability to use their knowledge of graphic notation. Although the children came from similar backgrounds, their responses showed varying constructs about the appropriate graphic notation to use in referential tasks. (SLD)

Used cross-sectional life span data from normative sample for Woodcock-Johnson Psycho-Educational Battery to examine independence of age-related cognitive changes in childhood and adulthood. Found that majority of age-related differences were shared across different cognitive variables and were well predicted by individual differences in…
