The present study examined the developmental change in number and length acuities and their respective relationship with achievement in various domains of mathematics in second vs. fourth graders. Length acuity was measured with a comparison task, in which participants were asked to choose the longer between a pair of lines. Number acuity was…

This study investigated potential differences in inductive behavioural and verbal strategy-use between children (aged 6-8 years) from indigenous and non-indigenous backgrounds. This was effected by the use of an electronic device that could present a series of tasks, offer scaffolded assistance and record children's responses. Children from…

The aim of the cross-sectional study was to reveal what coping strategies 8, 10- and 12-year-old Hungarian students (N?=?167) use in situations that are frustrating, either for themselves or their peers. The coping strategies in school situations were assessed by our own questionnaires. The instrument enables the investigation of the following…

The present study was undertaken to provide preliminary data on norms for the Human Drawings test for children ages 5-11, in Turkey. Four hundred and thirty children from two different schools, in two different socio-economic levels, were given the Human Figure Drawings. One was a private school in an affluent part of the city, and the other one…

Educational research suggests that lower-income children exhibit poor general executive functioning relative to their higher-income peers. Meanwhile, sports psychology research suggests that an acute bout of aerobic exercise improves executive functioning in children. Yet, it has never been determined if such exercise (1) specifically improves the…

The study aimed to field-test a Greek version of the Wechsler Quicktest and to examine its psychometric properties. The Quicktest was individually administered to 208 students, aged 5-14 years, along with a reading test. Based on the Rasch analysis, data for the Quicktest subtests showed acceptable fit to the model. Also, correlations were found…

Being bullied is associated with a psycho-social maladjustment during childhood. One hitherto largely overlooked correlate is disrupted classroom concentration. Using data collected from 364 9-11-year-old children attending seven junior schools in the UK, we tested a model in which children's perceived safety in two contexts (classroom and…

Conflict management is a skill best learned early in life, and lays a foundation for the development of future relationships. The present study examined the strategies children use when negotiating roles in a dynamic play situation. Participants were 156 children (M age = 6.5 years) in 39 groups of four, who were videotaped in a play activity that…

Children's drawings are thought to be a mirror of a child's representational development. Research suggests that with age children develop more complex and symbolic representational strategies and reference points become more differentiated by gender. We collected two drawings from 109 5-13-year-old children (three age groups). Each child drew…

This study examined the role of variability and change in children's strategy performance within the context of spelling. The spelling ability of 34 eight- to nine-year-olds was examined using an experimental spelling task comprising 45 items, which varied with regard to rime unit frequency. The spelling task incorporated a series of consistent,…

Virtually all research affirms the importance of a general factor (i.e., Spearman's "g") in accounting for individual differences in intelligence (Spearman, 1904). However, some scholars have suggested that cognitive abilities are not organised uniformly across all levels of age and ability. Using standardisation data from the Woodcock Johnson…

Seventy-two 11-year-old students were tested on 32 dictated words containing two levels of both visual and phonemic complexity. Students were grouped within sexes on their extraversion scores on the Junior Eysenck Personality Inventory and quotients on the Raven's Matrices. Spelling performance was found to interact significantly with level of…

This study investigated the effect of individual differences in state anxiety on tasks tapping the central executive, phonological, and visuo-spatial components of working memory (WM). It was designed to test Eysenck and Calvo's processing efficiency theory (PET) which suggests that the phonological and executive components of WM may be important…
