Li, Danfeng; Zhang, Xuejing; Zhang, Li – Journal of Learning Disabilities, 2023
Developmental dyscalculia (DD) is a mathematics learning disorder that affects approximately 5% to 7% of the population. This study aimed to detect the underlying domain-specific and domain-general differences between DD and typically developing (TD) children. We recruited 9-year-old primary school children to form the DD group via a 2-year…

Chen, Youzhen; Lian, Rong; Yang, Lixian; Liu, Jianrong; Meng, Yingfang – Journal of Learning Disabilities, 2017
The effects of working memory (WM) demand and reminders on an event-based prospective memory (PM) task were compared between students with low and high achievement in math. WM load (1- and 2-back tasks) was manipulated as a within-subject factor and reminder (with or without reminder) as a between-subject factor. Results showed that high-achieving…

Chen, Xiaoying; Ye, Maolin; Chang, Lei; Chen, Weigang; Zhou, Renlai – Journal of Learning Disabilities, 2018
Working memory (WM) deficiency is a primary reason for the poor academic performance of children with learning disabilities (LDs). Studies have shown that the WM of typical children could be improved through training, and WM training contributes to improving their fluid intelligence and academic achievement. However, few studies have investigated…

Wang, Enguo; Du, Chenguang; Ma, Yujun – Journal of Learning Disabilities, 2017
This study reports the neurophysiological and behavioral correlates of digital memory retrieval features in Chinese individuals with and without dyscalculia. A total of 18 children with dyscalculia (ages 11.5-13.5) and 18 controls were tested, and their event-related potentials were digitally recorded simultaneously with behavior measurement.…

Wang, Xiaochen; Georgiou, George K.; Das, J. P.; Li, Qing – Journal of Learning Disabilities, 2012
The purpose of the present study was twofold: (a) to examine the extent to which Chinese dyslexic children experience deficits in phonological and orthographic processing skills and (b) to examine if Chinese dyslexia is associated with deficits in Planning, Attention, Simultaneous, and Successive (PASS) processing. A total of 27 Grade 4 children…

Ding, Yi; Guo, Jian-Peng; Yang, Ling-Yan; Zhang, Dake; Ning, Huan; Richman, Lynn C. – Journal of Learning Disabilities, 2013
This study examined reading performance of 102 Chinese Mandarin-speaking 4th graders in their second language (L2, English) as a function of performance in their first language (L1, Chinese). The results revealed that for Rapid Automatized Naming (RAN) and Rapid Alternating Stimulus (RAS) measures, the mean naming time decreased monotonically in…

Ding, Yi; Richman, Lynn C.; Yang, Ling-yan; Guo, Jian-peng – Journal of Learning Disabilities, 2010
The purpose of this study was to evaluate rapid automatized naming skills (RAN) and immediate memory processes in 243 Chinese Mandarin-speaking elementary readers (ranging from Grade 1 to Grade 5). For RAN subtests, the mean naming time decreased monotonically with grade level in good and average readers, and a similar trajectory was found in poor…
