Introduction: Social knowledge is an important aspect of social cognition that pertains to broader knowledge of social concepts and norms. People with intellectual disabilities are more likely to experience mental health challenges, and it's important to pay special attention to how comorbid conditions can affect their social cognition skills,…

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 sought to provide more insight into potential differences in progression of analogical reasoning comparing gifted with average-ability children taking into account age, using a dynamic testing approach, using graduated prompting techniques, in combination with microgenetic methods. The participants were between the ages of 5 and 8 years…

The research set out in this paper attempts to identify whether one of three conventional IQ tests is more capable of identifying intellectual potential amongst poor children in Dar es Salaam. To this end 1857 children from 17 government schools in poor districts of Dar es Salaam were asked to complete a questionnaire and undertake a range of…

Threshold theory predicts a positive correlation between IQ and creativity scores up to an IQ level of 120 and no correlation above this threshold. Primary school children were tested at beginning (N = 98) and ending (N = 70) of the school year. Participants performed the standard progressive matrices (SPM) and the Test of Creative…

Specific language impairment (SLI) is a heterogeneous disorder affecting various aspects of language. While most studies have investigated impairments in the domain of syntax and morphosyntax, little is known about compositional semantics and the process of deriving pragmatic meanings in SLI. We selected a group of sixteen monolingual…

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 purpose of the study was to reveal the cognitive characteristics of talented children who come from economically vulnerable contexts in Chile. Raven's Standard Progressive Matrices (SPM) was administered to a sample of 5,160 students who took part in the process of identification of gifted students from the program PENTA UC in Chile between…

Many Flynn effect (FE) studies compare scores across different editions of Wechsler's IQ tests. When construct changes are introduced by the test developers in the new edition, however, the presumed generational effects are difficult to untangle from changes due to test content. To remove this confound, we use the same edition of Wechsler…

The study aimed to examine whether Kurdish-Persian early Bilingual university students (EBL) and Persian Monolingual university students (ML) differ on tasks of executive function (EF). Thirty male EBL and 30 male ML students from Ferdowsi University of Mashhad completed a Persian Stroop Color-Word task (SCWT), Backward Digit Span Test (BDST),…

This study contrasted the effects of tutoring, multiple try and no feedback on children's progression in analogy solving and examined individual differences herein. Feedback that includes additional hints or explanations leads to the greatest learning gains in adults. However, children process feedback differently from adults and effective…

Sex differences on the Attention Test (AC), the Raven's Standard Progressive Matrices (SPM), and the Brazilian Cognitive Battery (BPR5), were investigated using four large samples (total N=6780), residing in the states of Minas Gerais and Sao Paulo. The majority of samples used, which were obtained from educational settings, could be considered a…

The article presents a study on metalinguistic, cognitive and metacognitive abilities in university students. A sample of 353 students was recruited; 178 of which from scientific and 175 from humanistic Faculties, with gender balance (M = 178; F = 175) whose age range was between 20 and 25 years old. They were administered a metalinguistic ability…

Research Findings: Several recent studies carried out in the United States and abroad (i.e., Asia and Europe) have demonstrated that the ability of young children to regulate their behavior (including inhibitory control, working memory, attentional control) significantly predicts their academic achievement. The current study examined the…

This study aimed to explore the recognition of emotional and non-emotional biological movements in children with severe and profound deafness. Twenty-four deaf children, together with 24 control children matched on mental age and 24 control children matched on chronological age, were asked to identify a person's actions, subjective states,…
