Research on adult age differences in language production has traditionally focused on either the production of single words or the properties of language samples. Older adults are more prone to word retrieval failures than are younger adults (e.g., Burke, MacKay, Worthley, & Wade, 1991). Older adults also tend to produce fewer ideas per utterance…

Background: Before a school speech-language pathologist (SLP) utilises a standardised speech-language test with a student with intellectual disability (ID), the clinician should carefully consider the purpose of the test and whether the test includes students with ID in the normative group. Method: This project reviewed 49 tests published between…

Researchers have hypothesized that words that are highly related semantically are more likely to occur within the same intonational phrase (F. zzaq;, 1988; E. O. Selkirk, 1984). D. Watson and E. Gibson (2004) proposed that semantic closeness can be captured by using the argument/adjunct distinction, such that intonational boundaries are more…

Errors involving universal quantification are common in contexts depicting sets of individuals in partial, one-to-one correspondence. In this article, we explore whether quantifier-spreading errors are more common with distributive quantifiers each and every than with all. In Experiments 1 and 2, 96 children (5- to 9-year-olds) viewed pairs of…

This study investigated personal narratives produced by children with and without learning disabilities in the context of naturalistic conversation. The high-point analysis was applied to compare the referential and evaluative aspects of children's personal narratives. Participants were 60 students in Grades 4 and 5 in public suburban schools,…

Clahsen and Felser's article (CF) is an important contribution to the field of psycholinguistics in several respects. First, it draws attention to the importance of a better understanding of the processing mechanisms utilized by child and adult language learners. Differences in these mechanisms may be responsible for the final outcome of the…

In this article, the author demonstrates that the semiotic model proposed by Charles Morris enables us to optimize our understanding of technical communication practices and provides a good point of inquiry. To illustrate this point, the author exemplifies the semiotic approaches by scholars in technical communication and elaborates Morris's model…

We summarize some of the most important findings from research evaluating the hypothesized causes of specific reading disability ("dyslexia") over the past four decades. After outlining components of reading ability, we discuss manifest causes of reading difficulties, in terms of deficiencies in component reading skills that might lead to such…

Syntactic knowledge is widely held to be partially innate, rather than learned. In a classic example, it is sometimes argued that children know the proper use of anaphoric "one," although that knowledge could not have been learned from experience. Lidz et al. [Lidz, J., Waxman, S., & Freedman, J. (2003). What infants know about syntax but couldn't…

Following up on an earlier positron emission tomography (PET) experiment (Indefrey et al., 2001), we used a scene description paradigm to investigate whether a posterior inferior frontal region subserving syntactic encoding for speaking is also involved in syntactic parsing during listening. In the language production part of the experiment,…

An adult of above normal intelligence, BL, underwent left hemispherectomy at age five, and subsequently graduated from college and has been regularly employed. Using standardized neuropsychological instruments, previous extensive testing had revealed optimal performance for a hemispherectomized subject. To probe communicative abilities in greater…

In this paper, we distinguish between two ways that an individual can construct a formal proof. We define a syntactic proof production to occur when the prover draws inferences by manipulating symbolic formulae in a logically permissible way. We define a semantic proof production to occur when the prover uses instantiations of mathematical…

Central questions in psycholinguistic studies on bilingualism are how bilinguals access words in their two languages, and how they control their language systems and solve the problem of cross-language competition. In their excellent paper "The architecture of the bilingual word recognition system: From identification to decision", Dijkstra and…

A self-paced reading experiment investigated processing of sentences containing a noun-phrase that could temporarily be mistaken as the direct-object argument of a verb in a subordinate clause but actually constituted the syntactic subject of the main clause (often referred to as an "early" vs. "late closure" ambiguity). Subcategorization…

This paper describes a developmental psychological approach to understanding giftedness. A theoretical model of exceptional expertise is used to frame our understanding of how gifted children's conceptual knowledge develops in a variety of domains and how the interplay of this conceptual knowledge with domain-specific skills results in rich,…
