The goal of the paper was to investigate whether morphological units -- stems and suffixes -- influence orthographic processing by modulating visual attention demands to the task. Orthographic processing was measured with a visual one-back task requiring letters to be detected within pseudowords not including stems/suffixes, or containing real…

Previous research findings indicate that young children from East Asia outperform their counterparts from Europe and North America on executive function (EF) tasks. However, very few cross-national studies have focused on EF development during middle childhood. The current study assessed the EF performance of 170 children in grades 2 and 4 from…

Several studies in Spanish and other languages have shown that, in a lexical decision task, children are more likely to accept pseudowords with a known morphological structure as words as compared to non-morphological pseudowords. Morphology also facilitates visual word recognition of actual words in children with reading difficulties. In the…

In contrast to the well documented male advantage in psychometric mental rotation tests, gender differences in chronometric experimental designs are still under dispute. Therefore, a systematic investigation of gender differences in mental rotation performance in primary-school children is presented in this paper. A chronometric mental rotation…

Two exploratory studies assessed the effects of an intervention on the math problem solving of students with Attention Deficit Hyperactivity Disorder (ADHD). In the first study, students were assessed on a visual task in a high stimulation classroom analog setting with and without the use of a fine motor activity. Results showed that the fine…

We examined the relationship between rapid naming speed (RAN) and Chinese character recognition accuracy and fluency. Sixty-three grade 2 and 54 grade 4 Taiwanese children were administered four RAN tasks (colors, digits, Zhu-Yin-Fu-Hao, characters), and two character recognition tasks. RAN tasks accounted for more reading variance in grade 4 than…
