Background: Vocabulary scores increase until approximately age 65 years and then remain stable or decrease slightly, unlike scores on tests of other cognitive abilities that decline significantly with age. Aims: To review the findings on ageing-related changes in vocabulary, and to discuss four methodological issues: research design; test type;…

This research aimed to examine the views of preservice mathematics teachers (PMTs) on mathematically giftedness. Case study, one of the qualitative research design, was used and the study involved 25 sophomore mathematics teaching undergraduate students from Turkey. Data were collected with a semi-structured interview form with open-ended…

Efforts have been made to promote children's interest in science, but little is known about how children's interest in science relates to other characteristics, such as science-specific curiosity, domain-general epistemic curiosity, and verbal intelligence. The current study examines how these factors relate to individual differences in children's…

Cognitive abilities and interests both play an important role in guiding knowledge acquisition, but most previous studies have examined them separately. The current study used a large and representative dataset to integrate interests and abilities using a person-centered approach that examines how distinct profiles of interests and abilities…

S.A. Mednick (1962) proposed a theory of creativity suggesting that highly creative individuals can produce more word associations to a stimulus than less creative individuals. Numerous studies have supported this theory using the Remote Associates Test (RAT) as the measure of creativity. Additionally, some studies have suggested that…

Limited longitudinal studies have explored the development of reading, along with its predictors, in a language characterized by shallow orthography and a simple syllabic structure. In a 5-year longitudinal study, we investigated the development of reading skills in 327 Italian-speaking children (male: n = 180, 55%) from Grade 1 (mean age = 6.16 ±…

Intellectual performance is highly heritable and robustly predicts lifelong health and success but the earliest manifestations of genetic effects on this asset are not well understood. This study examined whether early executive function (EF) or verbal performance mediate genetic influences on subsequent intellectual performance, in 561 U.S.-based…

Despite the lasting interest towards the relationship between intelligence and creativity, comparably less attention is paid to its age-related changes. Our paper considers the organization of fluid intelligence and psychometric indicators of creativity and is based on the experimental data obtained for children aged 11 (n = 99) and for young…

Predictors of expressive grammar were compared in formal and naturalistic assessment tasks for children with typically developing (TD) language and with Developmental Langauge Disorder (DLD). Standardized expressive language assessments were administered to 110 preschoolers. The parents of these children reported whether or not they were concerned…

This study utilized data from the Avon Longitudinal Study of Parents and Children (N = 14,860) to examine whether early-life family income (age 0-5) predicted long-term academic achievement (age 16-18) and to investigate the role of executive function (EF) assessed multiple times across age 7-11 in explaining this association. Task-based EF was a…

Background: In this study we aimed to explore how intelligence and executive functioning are related to decision-making regarding social situations in persons with mild ID. Method: We studied 80 vocational school students with mild ID; the controls were 80 students of a similar age. We assessed decision-making ability with the Important Life…

This study provides the first analyses connecting individual differences in infant attention to reading achievement through the development of executive functioning (EF) in infancy and early childhood. Five-month-old infants observed a video, and peak look duration and shift rate were video coded and assessed. At 10 months, as well as 3, 4, and…

This quasi-experimental study examined the impact of reading aloud using theme-based material on the change from baseline to study endpoint in Crystallized Intelligence (Gc) of first grade students (Kaufman & Kaufman, 2004). A total of 39 students (19 male, 20 female) from two districts in a Midwestern state were recruited to participate. To…

Research indicates that educational stratification may lead to a lower-track school culture of futility and a less academically-oriented culture among lower-track teachers, leading to both reduced study involvement and lower educational achievement among their students. This study investigated whether an anti-school culture in the lower tracks [in…

Background: To date, numbers of studies have indicated the important role of fine manual dexterity in typical and special populations. However, the relevant studies in Down's syndrome (DS) population is still limited. The purpose of this study was to investigate the determinants of manual dexterity in adolescents and young adults with DS. Methods:…
