Purpose: The purpose of this study was to examine the direct and indirect relations between short-term memory (STM), reading, oral language, and writing at the letter, word, and discourse levels in young, developing writers both cross-sectionally and longitudinally. Method: Participants were 449 English-speaking kindergarten students (52% female)…

Working memory allows us to hold specific pieces of information in an active and easily retrieved state, but what happens to that information during an unexpected interruption between study and test? To answer this question, we used a surprise trial paradigm in which an unexpected event precedes a probe of the observer's memory for a search…

Using Chinese characters, we investigated how stroke count and frequency of use influence attention and short-term memory (STM) encoding in Mainland Chinese speakers. To isolate specific components of attention we employed the Theory of Visual Attention (TVA), which allowed estimates of STM capacity, processing speed, and the threshold of visual…

This study analyzes the impact of certain cognitive processes on word and pseudoword reading in languages with different orthographic consistency (Spanish and Arabic) in the first year of Primary Education. The study was conducted with a group of 113 pupils from Algeria and another group of 128 pupils from Ecuador, from a middle-class background…

Visual working memory (VWM) is limited in both the "capacity" of information it can retain and the "rate" at which it encodes that information. We examined the influence of stimulus complexity on these 2 limitations of VWM. Observers performed a change-detection task with English letters of various fonts or letters from…

As a theory of skill acquisition, the instance theory of automatization posits that, after a period of training, algorithm-based performance is replaced by retrieval-based performance. This theory has been tested using alphabet-arithmetic verification tasks (e.g., is A + 4 = E?), in which the equations are necessarily solved by counting at the…

This study examined whether different cognitive correlates are associated with spelling of different target types, such as phonologically consistent and inconsistent syllables, of Korean Hangul among 94 five-year-old first language (L1) Korean children and 41 foreign language (FL) learners who are Hong Kong Chinese college students. Korean…

This article describes the development and psychometric properties of a new Dyslexia Marker Test for Children (Dysmate-C). The test was designed to identify Norwegian students who need special instructional attention. The computerized test includes measures of letter knowledge, phoneme awareness, rapid automatized naming, working memory, decoding,…

Rapid Automatic Naming (RAN) has been widely recognized as a reliable predictor of reading proficiency. Although RAN represents the speed of cognitive processing, there are few studies that have addressed RAN as a cognitive process in its own right Furthermore, RAN performance of ELL (English Language Learners) has been less frequently…

We examined whether akshara knowledge, phonological awareness, phonological memory, and RAN predict variability in word and nonword reading skills in Grade 1-4 children (N = 200) learning to read Sinhala. Hierarchical regression analyses showed that akshara knowledge had the strongest unique association with both word and nonword reading accuracy…

Stimuli that are fluently processed are more likely to be called "old" on a recognition memory test compared with less fluently processed stimuli. The goal of the current study was to investigate how the perceived diagnostic value of fluency is affected by a match between encoding and test conditions. During the encoding phase,…

According to some views of cognitive growth, the development of working memory capacity can account for increases in the complexity of cognition. It has been difficult to ascertain, though, that there actually is developmental growth in capacity that cannot be attributed to other developing factors. Here we assess the role of item familiarity. We…

To clarify the link between anomalous letter processing and developmental dyslexia, we examined the impact of surrounding contours on letter vs. pseudo-letter processing by three groups of children--phonological dyslexics and two controls, one matched for chronological age, the other for reading level--and three groups of adults differing by…

Previous studies have indicated cross cultural differences in conscious processes, such that Asians have a global preference and Westerners a more analytical one. We investigated whether these biases also apply to unconscious knowledge. In Experiment 1, Japanese and UK participants memorized strings of large (global) letters made out of small…

This study investigated the relationship among working memory, processing speed, math performance, and reactivity to stress in 83 Grade 1 children. Specifically, 39 children with math disability (MD) were compared to 44 children who are typically achieving (TA) in mathematics. It is the first study to use a physiological index of stress (salivary…
