Visuo-spatial reasoning tests, such as Raven's matrices, Cattell's culture-fair test, or various subtests of the Wechsler scales, are frequently used to estimate intelligence scores in the context of inter-racial comparisons. This has led to several high-profile works claiming that certain ethnic groups have lower intelligence than others,…

The study aimed to investigate the effect of a training program on improving working memory for students with learning difficulties in reading Arabic. The study sample consisted of (10) students with learning disabilities from Basic Education students from the fifth and sixth grades, and those between the ages (10-11) years as a pilot group and…

The relationships among visual and auditory temporal processing, rapid naming, and oral reading fluency in Chinese children with and without dyslexia were examined. Primary school-aged Chinese children with dyslexia (N = 47) and chronological-age-matched controls (N = 47) were recruited. Temporal processing, rapid naming, oral reading fluency,…

Mathematical giftedness (MG) is an intriguing phenomenon, the nature of which has yet to be sufficiently explored. This study goes a step further in understanding how MG is related to expertise in mathematics (EM) and general giftedness (G). Cognitive testing was conducted among 197 high school students with different levels of G and of EM. Based…

Recent advances in understanding visual working memory, the limited information held in mind for use in ongoing processing, are extended here to examine auditory working memory development. Research with arrays of visual objects has shown how to distinguish the capacity, in terms of the "number" of objects retained, from the…

This study examined the extent to which Chinese children with dyslexia show temporal processing deficits in addition to deficits in various forms of attention. In total, 104 Chinese children in primary school (Grades 3-6) were recruited in Taiwan. Half of the children were identified as having dyslexia, and the other half were typically developing…

In order to make appropriate educational recommendations, psychologists must understand how cognitive test scores influence specific academic outcomes for students of different ability levels. We used data from the WISC-V and WIAT-III (N = 181) to examine which WISC-V Index scores predicted children's specific and broad academic skills and if…

In the present study, 144 second- and 150 fourth-grade Chinese students were recruited to complete a Chinese character learning task to explore the specific contributions of sensory-motor components (i.e., visual, motor, and haptic systems) of handwriting to Chinese character learning. After matching for age, nonverbal IQ, and a series of…

Background: Interpreting cognitive assessment results for individuals from indigenous communities can be complex. Factors such as culture, language, and education may influence results. Although there is research regarding the cognitive assessment of typically functioning individuals from indigenous communities there is limited information on…

A good deal of research purports that bilingualism has a positive effect on some aspects of cognitive functioning. However, this effect is not consistent, and little research examines trajectories of cognitive skill development in bilingual children. Moreover, it remains unclear whether different types of bilingualism impact how cognitive…

A wide share of secondary school children does not reach the expected competence level in reading. These children could benefit from more efficient intervention responses, providing a better understanding of their cognitive weaknesses/deficits. Our aim was to explore the cognitive heterogeneity of a population of poor readers identified from a…

Social perception is important because it can affect the way intelligence is expressed during social interactions at school, home, and work. This study (N = 800) of adolescents and adults (age range = 16-91) examined which specific aspects of intelligence are associated with social perception (a composite of affect labelling, linking prosody to…

Borderline intellectual functioning is a neurodevelopmental condition characterized by an intelligence quotient (IQ) in the range of 70-85. The present study aimed to investigate the mathematical abilities and the working memory of students with borderline intellectual functioning (BIF). The sample group included 10 year-old students with BIF (n =…

This study examined the factor structure of the Wechsler Intelligence Scale for Children-Fifth Edition (WISC-V) with four standardization sample age groups (6-8, 9-11, 12-14, 15-16 years) using exploratory factor analysis (EFA), multiple factor extraction criteria, and hierarchical EFA not included in the WISC-V "Technical and Interpretation…

More than 50 years since the introduction of the concept of divergent production, little progress has been made in the development of parsimonious theoretical models that sufficiently explain creativity. Recently, the optimal foraging theory has been used to explain the search for items in memory tasks, suggesting the correspondence between the…
