Using Malaysia TIMSS 2015 data, this study examined the association between eighth grade students' science achievement and mathematics score and the determining factors of science achievement. A total of 9,726 students participated in TIMSS 2015 with an average score of 508.60 with standard deviation of 89.86 for science and 501.57 with standard…

This study investigated to what extent the Peabody Picture Vocabulary Test (PPVT-4) is a reliable tool for measuring vocabulary knowledge of English as a second language (L2), and to what extent L1 characteristics affect test outcomes. The PPVT-4 was administered to Dutch pupils in six different age groups (4-15 years old) who were or were not…

Molecular processes are highly complex, and are frequently difficult for high school and college students to comprehend. Because of the importance of visualization in learning, along with formative assessment of student understanding, utilization of 3D modeling software aids both educators and students alike. The activity described below required…

This study examines the response patterns of 288 Spanish-English dual language learners on a standardized test of receptive Spanish vocabulary. Investigators analyzed responses to 54 items on the "Test de Vocabulario en Imagenes" (TVIP) [Dunn, L. M., D. E. Lugo, E. R. Padilla, and L. M. Dunn. 1986. "Test de Vocabulario en Imganes…

This study addresses the question as to what cognitive abilities influence performance on article choice and direct object scrambling in high-functioning Dutch-speaking children with Autism Spectrum Disorder (ASD). Schaeffer (2016/2018) shows that a group of 27 high-functioning Dutch-speaking children with ASD, aged 5-14, overgenerates the…

This study describes the barriers and supportive factors for learning about and using Information and Communication Technologies (ICT) present during a learning intervention designed to enable older adults to use ICT for fostering healthy aging in terms of promoting functional ability. Forty-one adults, older than 60 years, participated in a…

Multiple sclerosis is an inflammatory autoimmune disease that attacks the central nervous system through the destruction of myelin. Frequently cited symptoms include cognitive impairment as a hallmark repercussion, neuropsychological executive dysfunction, and psychosocial disturbances, such as affective disorders and fatigue. Other symptomatology…

Children's memberships in social groups have profound effects on their motivation. Stereotypes about social groups shape children's beliefs about what is expected for their group members. These beliefs can influence children's developing beliefs about themselves (self-perceptions). In this article, I review research on how gender stereotypes…

Visual-spatial ability is a multifaceted component of intelligence that has predictive validity for future achievement in science, technology, engineering, and mathematics (STEM) occupations. Although identification and development of STEM talent is a national priority, visual-spatial ability is rarely measured and relatively neglected in gifted…

We determined how various cognitive abilities, including several measures of a proposed domain-specific number sense, relate to mathematical competence in nearly 100 9-year-old children with normal reading skill. Results are consistent with an extended number processing network and suggest that important processing nodes of this network are…

Phelan-McDermid syndrome (PMS) is a single-locus cause of developmental delay, autism spectrum disorder, and minimal verbal abilities. There is an urgent need to identify objective outcome measures of expressive language for use in this and other minimally verbal populations. One potential tool is an automated language processor called Language…

The primary focus of the present experiment was to study participants' self-talk during conditional discrimination training and test for the emergence of conditional relations consistent with equivalence. Eighteen adult participants were exposed to either a Many-to-One (MTO) or a One-to-Many (OTM) training structure arranged as a 6-s delayed…

This study explored the development of Ecuadorian Kindergartners' spontaneous focusing on numerosity (SFON) during the kindergarten year, as well as the contribution of early numerical abilities to this development. One hundred Kindergartners coming from ten classrooms received two SFON tasks, one at the beginning and one at the end of the school…

Current evidence provides support for the idea that time is mentally represented by spatial means, i.e., a left-right mental timeline. However, available studies have tested only factual events, i.e., those which have occurred in the past or can be predicted to occur in the future. In the present study we tested whether past and future potential…

Fluency is an important construct in clinical assessment and in cognitive taxonomies. In the Cattell-Horn-Carroll (CHC) model, Fluency is represented by several narrow factors that form a subset of the long-term memory encoding and retrieval (Glr) broad factor. The CHC broad classification of Fluency was evaluated in five data sets, and the CHC…
