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…

Background: Efficient word identification is directly tied to strong mental representations of words, which include spellings, meanings and pronunciations. Orthographic learning is the process by which spellings for individual words are acquired. Methods: In the present study, we combined the classic self-teaching paradigm with eye tracking to…

Holistic processing (HP) of faces refers to the obligatory, simultaneous processing of the parts and their relations, and it emerges over the course of development. HP is manifest in a decrement in the perception of inverted versus upright faces and a reduction in face processing ability when the relations between parts are perturbed. Here,…

The current study investigated the role of visual short-term memory, working memory, and declarative memory as individual differences in the earliest stages of vocabulary and syntactic learning in "Duolingo"-based language instruction. Thirty-eight L1-Greek adults completed memory tasks and engaged in learning Navajo on…

The purpose of this follow-up study was to determine the specific contribution of phonological processing abilities, including phonological awareness (PA), rapid automatized naming (RAN) and verbal short-term memory (VSTM), as well as visual perception (VP), in word reading accuracy. A sample of 62 native Arabic speaking children from Grade 1…

The typical pattern of results in divided attention experiments is that subjects in a full attention (FA) condition perform markedly better on tests of memory than subjects in a divided attention (DA) condition which forces subjects to split their attention between studying to-be-remembered stimuli and completing some peripheral task.…

The goal of the current study is to assess the temporal dynamics of vision and action to evaluate the underlying word representations that guide infants' responses. Sixteen-month-old infants participated in a two-alternative forced-choice word-picture matching task. We conducted a moment-by-moment analysis of looking and reaching behaviors as they…

Adult literacy training is known to be difficult in terms of teaching and maintenance (Abadzi, 2003), perhaps because adults who recently learned to read in their first language have not acquired reading automaticity. This study examines fast word recognition process in neoliterate adults, to evaluate whether they show evidence of perceptual…

Through computational modeling, here we examine whether visual and task characteristics of writing systems alone can account for lateralization differences in visual word recognition between different languages without assuming influence from left hemisphere (LH) lateralized language processes. We apply a hemispheric processing model of face…

Research on bilingual word recognition suggests that lexical access is nonselective with respect to language, i.e., that word representations of both languages become active during recognition. One piece of evidence supporting nonselective access is that bilinguals recognize cognates (words that are identical or similar in form and meaning in two…

Visual speech perception has become a topic of considerable interest to speech researchers. Previous research has demonstrated that perceivers neurally encode and use speech information from the visual modality, and this information has been found to facilitate spoken word recognition in tasks such as lexical decision (Kim, Davis, & Krins,…

Participants report briefly-presented words more accurately when two copies are presented, one in the left visual field (LVF) and another in the right visual field (RVF), than when only a single copy is presented. This effect is known as the "redundant bilateral advantage" and has been interpreted as evidence for interhemispheric cooperation. We…

This study investigated the linguistic processing of visual speech (video of a talker's utterance without audio) by determining if such has the capacity to prime subsequently presented word and nonword targets. The priming procedure is well suited for the investigation of whether speech perception is amodal since visual speech primes can be used…
