In the search for mechanisms that contribute to dyslexia, the term "attention" has been invoked to explain performance in a variety of tasks, creating confusion since all tasks do, indeed, demand "attention." Many studies lack an experimental manipulation of attention that would be necessary to determine its influence on task…

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…

Given the well-documented consonant primacy established in Roman script, this study examined the role of consonants and vowels in lexical decision of Korean "Hangul" among skilled Korean readers in order to identify whether the salient role of consonants over vowels would be script-universal or script-specific. Three experiments were…

In four experiments, we investigated the impact of letter case (lower case vs. UPPER CASE) on the processing of sequences of written words. Experiment 1 used the rapid parallel visual presentation (RPVP) paradigm with postcued identification of one word in a five-word sequence. The sequence could be grammatically correct (e.g., "the boy likes…

A growing number of studies have probed the effectiveness of certain exercise formats in the learning of multi-word expressions (MWEs) in classroom settings. However, a number of important variables, such as MWE retention over an extended period of time and the role of repetition, have so far not been considered. Furthermore, studies have focused…

Recently, there has been growing concern about how to most effectively support the literacy development of beginning and struggling readers with regard to helping them learn to effortlessly identify the huge number of words that proficient readers ultimately learn to read with automaticity. Some, noting the critical importance of phonics…

Reading plays an essential role in our everyday lives. The aim of this study is to investigate how letters are represented in the brain using the unique characteristics of the Arabic language, which can be written with 2 different scripts. The hypothesis proposed is that the processing of script is sound based: Phonology is what determines letter…

Does visuospatial orientation influence repetition and transposed character (TC) priming effects in logographic scripts? According to perceptual learning accounts, the nature of orthographic (form) priming effects should be influenced by text orientation (Dehaene, Cohen, Sigman, & Vinckier, 2005; Grainger & Holcomb, 2009). In contrast,…

The "familiarity effect" (Shen and Reingold, "Perception & Psychophysics" 63(3):464-475, 2001) is a phenomenon in which unfamiliar symbols perceptually "pop-out" when placed among familiar symbols (e.g., letters). In contrast, searching for familiar symbols among unfamiliar symbols is more challenging. Failure to…

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…

In 1924 Jabbar Baghcheban created a manual system that employed the phonetic characteristics of spoken Persian and Perso-Arabic orthography for use in the education of deaf students (Ibrahimi 2007). This article is a first exploration of variation and change in this system as it has evolved into the Iranian manual alphabet. Data on the…

Mastery of the alphabetic principle necessitates learning letter--sound correspondences. In this study, we found evidence of the importance of spoken phonology in the letter--sound learning of 89 deaf or hard-of-hearing (DHH) preschoolers. Only DHH children with at least some ability to perceive speech were included in the study. DHH children were…

Some aspects of Chinese literacy development do not conform to patterns of literacy development in alphabetic orthographies. Four are highlighted here. First, semantic radicals are one aspect of Chinese characters that have no analogy to alphabetic orthographies. Second, the unreliability of phonological cues in Chinese along with the fact that…

The goal of the study was to examine the association between visual-attentional span and lexical decision in skilled adult readers. In the span tasks, an array of letters was presented briefly and recognition or production of a single cued letter (partial span) or production of all letters (whole span) was required. Independently of letter…

While hemispheric differences in global/local processing have been reported by various studies, it is still under dispute at which processing stage they occur. Primarily, it was assumed that these asymmetries originate from an early perceptual stage. Instead, the content-level binding theory (Hubner & Volberg, 2005) suggests that the hemispheres…
