Kyttälä, Minna; Björn, Piia M. – Scandinavian Journal of Educational Research, 2022
The main aim of the study was to differentiate adolescent profiles by math performance at the beginning and end of the final two years of lower secondary school, and relevant baseline attributes (literacy skills, general cognitive ability, math anxiety), and to investigate how these profiles differed by gender and math avoidance. A total of 193…

Yilin Huang; Yifan Liu; Qiong Hu; Qiong Zhang – Journal of Attention Disorders, 2024
Objective: To examine the manifestation of cognitive control deficit of children with different levels of hyperactivity, an "at risk" dimension for ADHD. Method: A group of children with high hyperactivity (N = 40) and another group of children with low levels of hyperactivity (N = 38) performed a modified stop-signal anticipation task,…

Ashworth, Anna; Hill, Catherine M.; Karmiloff-Smith, Annette; Dimitriou, Dagmara – Developmental Science, 2017
Sleep plays an active role in memory consolidation. Because children with Down syndrome (DS) and Williams syndrome (WS) experience significant problems with sleep and also with learning, we predicted that sleep-dependent memory consolidation would be impaired in these children when compared to typically developing (TD) children. This is the first…

Skagerlund, Kenny; Träff, Ulf – Journal of Learning Disabilities, 2016
This study investigated if developmental dyscalculia (DD) in children with different profiles of mathematical deficits has the same or different cognitive origins. The defective approximate number system hypothesis and the access deficit hypothesis were tested using two different groups of children with DD (11-13 years old): a group with…

Jensen, Arthur R.; Munro, Ella – Intelligence, 1979
Information processing was measured in terms of reaction time and movement time to stimulus displays which differed in amount of information transmitted. Only reaction time increased as a linear function of number of bits in the stimulus display. Both show individual differences which significantly correlated with intelligence. (Author/RD)

Levin, Joel R.; And Others – 1974
The paired-associate learning of 52 fourth graders was related to measures of cognitive ability obtained the previous year. Subjects were administered the paired-associate task under one of three variations: at a comfortable rate with standard instructions; at a comfortable rate with a potentially effective learning strategy (visual imagery); and…
