Six experiments apply the masked priming paradigm to investigate how letter position information is computed during printed word perception. Primes formed by a subset of the target's letters facilitated target recognition as long as the relative position of letters was respected across prime and target (e.g., "arict" vs. "acirt" as primes for the…

It has been commonly agreed that developmental dyslexia in different languages has a common biological origin: a dysfunction of left posterior temporal brain regions dealing with phonological processes. Siok, Perfetti, Jin, and Tan (2004, "Nature," 431, 71-76) challenge this biological unity theory of dyslexia: Chinese dyslexics show no deficits…

We present two bilingual patients without language disorders in whom involuntary language switching was induced. The first patient switched from Dutch to English during a left-sided amobarbital (Wada) test. Functional magnetic resonance imaging yielded a predominantly left-sided language distribution similar for both languages. The second patient…

To assign lexical stress when reading, the Greek reader can potentially rely on lexical information (knowledge of the word), visual-orthographic information (processing of the written diacritic), or a default metrical strategy (penultimate stress pattern). Previous studies with secondary education children have shown strong lexical effects on…

We report four act-out experiments testing the sensitivity of adults and three- to five-year-old children to the distinction between restrictive and non-restrictive relative clauses in English. Specifically, we test knowledge of the fact that restrictive relative clauses cannot modify a proper name head, and of the fact that relatives introduced…

Spoken language consists of a complex, sequentially arrayed signal that contains patterns that can be described in terms of statistical relations among language units. Previous research has suggested that a domain-general ability to learn structured sequential patterns may underlie language acquisition. To test this prediction, we examined the…

The acquisition of new skills over a life span is a remarkable human ability. This ability, however, is constrained by age of acquisition (AoA); that is, the age at which learning occurs significantly affects the outcome. This is most clearly reflected in domains such as language, music, and athletics. This article provides a perspective on the…

Evidence from recent experiments that monitored attention in clipart scenes during spoken comprehension suggests that people preferably rely on non-stereotypical depicted events over stereotypical thematic knowledge for incremental interpretation. "The Coordinated Interplay Account [Knoeferle, P., & Crocker, M. W. (2006). "The coordinated…

Two experiments examined the dynamics of lexical activation in spoken-word recognition. In both, the key materials were pairs of onset-matched picturable nouns varying in frequency. Pictures associated with these words, plus two distractor pictures were displayed. A gating task, in which participants identified the picture associated with…

Two experiments are reported that examine how manipulations of visual attention affect speakers' linguistic choices regarding word order, verb use and syntactic structure when describing simple pictured scenes. Experiment 1 presented participants with scenes designed to elicit the use of a perspective predicate ("The man chases the dog/The dog…

Autism spectrum disorders (ASDs) are characterized by correlated deficiencies in social and language development. This study explored a fundamental aspect of auditory information processing (AIP) that is dependent on social experience and critical to early language development: the ability to compartmentalize close-sounding speech sounds into…

Individuals with the rare genetic disorder, Williams syndrome, have an unusual cognitive profile with relatively good language abilities but poor non-verbal and spatial skills. This study explored the interaction between linguistic and spatial functioning in Williams syndrome by investigating individuals' comprehension of spatial language. A group…

This paper reports the results of four dual-task experiments that were designed to determine the extent of domain-specificity of the verbal working memory resources used in linguistic integrations. To address this question, syntactic complexity was crossed in a 2x2 design with the complexity of a secondary task, which involved either (1)…

Both classroom instruction and lexical database development stand to benefit from applied research on sign language, which takes into consideration American Sign Language rules, pedagogical issues, and teacher characteristics. In this study of technical science signs, teachers' experience with signing and, especially, knowledge of content, were…

This study examined the role of phonological memory in second language (L2) grammar learning in a group of native French-speaking children undergoing a 5-month intensive English program. Phonological memory (as referenced by Arabic [ANWR] and English [ENWR] nonword repetition tasks), L2 vocabulary (receptive and productive vocabulary knowledge),…
