Layes, Smail; Bouakkaz, Torkia – British Journal of Special Education, 2022
The present study explored whether phonological awareness (PA), morphological awareness (MA) and visual attention (VA) independently predict word and pseudoword reading accuracy in native Arabic-speaking children from grades 4 and 5. A total of 141 participants took part in the study, and were divided into two groups of readers with (n = 30) and…

Vinci-Booher, Sophia; James, Karin H. – Developmental Science, 2020
Letter production through handwriting creates visual experiences that may be important for the development of visual letter perception. We sought to better understand the neural responses to different visual percepts created during handwriting at different levels of experience. Three groups of participants, younger children, older children, and…

Antzaka, Alexia; Martin, Clara; Caffarra, Sendy; Schlöffel, Sophie; Carreiras, Manuel; Lallier, Marie – Reading and Writing: An Interdisciplinary Journal, 2018
The present study investigated whether orthographic depth can increase the bias towards multi-letter processing in two reading-related skills: visual attention span (VAS) and rapid automatized naming (RAN). VAS (i.e., the number of visual elements that can be processed at once in a multi-element array) was tested with a visual 1-back task and RAN…

Schneider, Darryl W. – Journal of Experimental Psychology: Learning, Memory, and Cognition, 2016
Transition effects in task-cuing experiments can be partitioned into task switching and cue repetition effects by using multiple cues per task. In the present study, the author shows that cue repetition effects can be partitioned into perceptual and conceptual priming effects. In 2 experiments, letters or numbers in their uppercase/lowercase or…

Liu, Sisi; Wang, Li-Chih; Liu, Duo – Journal of Research in Reading, 2019
Background: There is emerging evidence that individuals with developmental dyslexia show deficits in visual-spatial attention. This study focused on visual searches and examined whether visual search deficits would be found in Chinese children with dyslexia. More importantly, we examined the associations between dyslexia and distinct types of…

Children with Autism Detect Targets at Very Rapid Presentation Rates with Similar Accuracy as Adults
Hagmann, Carl Erick; Wyble, Bradley; Shea, Nicole; LeBlanc, Megan; Kates, Wendy R.; Russo, Natalie – Journal of Autism and Developmental Disorders, 2016
Enhanced perception may allow for visual search superiority by individuals with Autism Spectrum Disorder (ASD), but does it occur over time? We tested high-functioning children with ASD, typically developing (TD) children, and TD adults in two tasks at three presentation rates (50, 83.3, and 116.7 ms/item) using rapid serial visual presentation.…

Petersen, Anders; Andersen, Tobias S. – Journal of Experimental Psychology: Human Perception and Performance, 2012
The psychometric function of single-letter identification is typically described as a function of stimulus intensity. However, the effect of stimulus exposure duration on letter identification remains poorly described. This is surprising because the effect of exposure duration has played a central role in modeling performance in whole and partial…

Rojas-Barahona, Cristian A.; Förster, Carla E.; Moreno-Ríos, Sergio; McClelland, Megan M. – Early Education and Development, 2015
Research Findings: The present study evaluated the impact of a working memory (WM) stimulation program on the development of WM and early literacy skills (ELS) in preschoolers from socioeconomically deprived rural and urban schools in Chile. The sample consisted of 268 children, 144 in the intervention group and 124 in the comparison group. The…

Richman, Howard B.; Simon, Herbert A. – Psychological Review, 1989
This study showed that the Elementary Perceiver and Memorizer (EPAM) can explain letter recognition phenomena earlier simulated by the connectionist Interactive Activation Model of word perception. EAPM, a model of learning and recognition in the form of a computer program, has previously explained many aspects of learning and perception. (TJH)

Kim, Jeesun; Davis, Chris – Reading and Writing: An Interdisciplinary Journal, 2004
The vast majority of work on the processing characteristics of poor readers has been conducted with readers of English. In this article we report on results that outline the processing characteristics of poor readers of the Korean alphabetic-syllabic script, "Hangul." Three groups of readers (10 good readers, 10 poor readers and 9 poor readers…
