Social mastery motivation and parental response are important correlates of children's vocabulary and self-regulation skills, but little research has examined their relationships collectively. This study investigated the direct relationships among social mastery motivation (active interaction and positive affect frequencies), parental response,…

The present study examined the mediating role of fluid intelligence between working memory (WM) and academic achievement and tested the invariance of this model across gender in a random sample of university students (N = 560, 228 boys & 332 girls). Heart and Flower task (Diamond, 2013) and Raven's Standard Progressive Matrices[superscript TM]…

Intelligence involves the ability to think, solve problems, analyze situations, and understand social values, customs, and norms. Intelligence is a general mental capability that involves the ability to reason, plan, think abstractly, comprehend ideas and language, and learn. Intellectual ability involves comprehension, understanding, and learning…

The relationship between IQ, metacognition, and self-perception of quality of life as measured by the Mooney checklist was explored. Participants who were hearing and deaf and hard of hearing (D/HH) were compared using these outcome variables, with gender as an additional grouping variable. Results revealed performances on these measures were…

Considerable recent work suggests that mathematical abilities in children correlate with the ability to estimate numerosity. Does math correlate only with numerosity estimation, or also with other similar tasks? We measured discrimination thresholds of school-age (6- to 12.5-years-old) children in 3 tasks: numerosity of patterns of relatively…

The purpose of this study was to examine the relationship between metacognition as measured in real-life situations and IQ scores as reflected by performance on the Raven Standard Progressive Matrices Scale. It is also intended in this study to report on whether or not there were significant differences in performance on the metacognitive…

The relationships between visuo-spatial abilities and geometry performances in school-aged children were examined. A battery of tests assessing non-verbal reasoning, visuo-spatial mental imagery, and academic achievement in geometry (i.e., geometric knowledge and geometric problem-solving competencies) was presented to 162 8-9.5-year-old pupils…

Despite the important role assigned to analogical reasoning (AR) in cognition and language, the relationship between this ability and language skills in the emergent literacy period has not been sufficiently studied, especially in Spanish speakers. To explore this link, we examined two modalities of AR (verbal and non-verbal) as predictors of…

Sleep spindles act as a powerful marker of individual differences in cognitive ability. Sleep spindle parameters correlate with both age-related changes in cognitive abilities and with the age-independent concept of IQ. While some studies have specifically demonstrated the relationship between sleep spindles and intelligence in young children, our…

This study aimed to investigate differences in the mathematical problem-solving and metacognitive skills of the fifth-grade students in Oman as a function of gender and level of academic achievement. The participants were 90 grade five students randomly selected from one educational governorate in the Sultanate of Oman. They were evenly divided…

The study aimed to investigate variations in addition and subtraction fluency by observing grade three students in Norway (n = 253, M[ subscript age] = 8.38 y.) and Finland (n = 209, M[subscript age] = 9.35 y.) while controlling for their age and non-verbal reasoning. Gender differences were also examined. The focus of the study was on the…

The present study evaluated the extent to which literacy skills (reading fluency, written spelling, and reading comprehension), together with nonverbal reasoning, prior knowledge, and gender, are related to students' online research and comprehension (ORC) performance. The ORC skills of 426 sixth graders were measured using a Finnish adaptation of…

The current study examines the relationship between bilingual children's dual language experience (i.e. language input, language output and vocabulary proficiency), and their social-emotional and behavioral skills. Data were analysed from 805 Singaporean bilingual preschoolers (ages 4; 1-5; 8 years), who are learning English and either Mandarin (n…

The purpose of the present study was to evaluate the psychometric properties of a shortened version of the Raven Standard Progressive Matrices (SPM) under an item response theory framework (the one- and two-parameter logistic models). The shortened Raven SPM was administered to N = 453 cognitively healthy adults aged between 24 and 83 years. The…

The present study investigated gender differences in social mastery motivation, vocabulary knowledge, behavioral self-regulation, and socioemotional skills and examined the relationships among this knowledge and these skills by gender. Participants were 134 Chinese children (68 boys, M age = 3.80; 66 girls, M age = 3.89) and their parents…
