Alma Guilbert – Journal of Cognition and Development, 2024
Children are limited in visual search accuracy and this ability increases from childhood to adolescence. Developmental limitations in visual search could be related to children's difficulties in efficiently planning and executing their search, often assessed with cancellation tasks. However, few studies have examined age-related changes in visual…

Bildiren, Ahmet; Bikmaz Bilgen, Özge; Korkmaz, Mediha – SAGE Open, 2021
The aim of the present study is to develop a national non-verbal cognitive ability test in Turkey. Test items were developed during the first stage and applied as a pilot study on 3,073 children in the age interval of 4 to 13. The test was given its final form based on the values of item difficulty, item distinctiveness, item total score…

Serdarevic, Fadila; van Batenburg-Eddes, Tamara; Mous, Sabine E.; White, Tonya; Hofman, Albert; Jaddoe, Vincent W. V.; Verhulst, Frank C.; Ghassabian, Akhgar; Tiemeier, Henning – Developmental Science, 2016
Within a population-based study of 3356 children, we investigated whether infant neuromotor development was associated with cognition in early childhood. Neuromotor development was examined with an adapted version of Touwen's Neurodevelopmental Examination between 9 and 20 weeks. Parents rated their children's executive functioning at 4 years. At…

Batterjee, Adel A.; Khaleefa, Omar; Ali, Khalil; Lynn, Richard – Intelligence, 2013
Normative data for 8-15 year olds for the Standard Progressive Matrices in Saudi Arabia were obtained in 1977 and 2010. The 2010 sample obtained higher average scores than the 1977 sample by 0.78d, equivalent to 11.7 IQ points. This represents a gain of 3.55 IQ points a decade over the 33 year period.

Namazi, Mahchid; Thordardottir, Elin – International Journal of Bilingual Education and Bilingualism, 2010
We explored the relationship between working memory (WM) and visually controlled attention (CA) in young bilingual and monolingual children. Previous research has shown that balanced bilingual children outperform monolinguals in CA. However, it is unclear whether this advantage is truly associated with bilingualism or whether potential WM and/or…

Rojahn, Johannes; Naglieri, Jack A. – Intelligence, 2006
Lynn [Lynn, R., 2002. Sex differences on the progressive matrices among 15-16 year olds: some data from South Africa. "Personality and Individual Differences 33," 669-673.] proposed that biologically based developmental sex differences produce different IQ trajectories across childhood and adolescence. To test this theory we analyzed the…
