The current study tested 2 models of inhibition in 45 children with language impairment and 45 children with normally developing language; children were aged 7 to 12 years. Of interest was whether a model of inhibition as a mental-control process (i.e., executive function) or as a mental resource would more accurately reflect the relations among…

Background: More limited working memory capacity and slower processing for language and cognitive tasks are characteristics of many children with language difficulties. Individual differences in processing speed have not consistently been found to predict language ability or severity of language impairment. There are conflicting views on whether…

The hypothesis indicating an overactivation of the lexico-semantic network in children with specific language impairment (SLI) was tested using an auditory pair-primed paradigm (PPP), where participants made a lexical-decision on the second word of a noun pair that could be semantically related, or not, to the first one. Though children with SLI…

In this study, we explored whether the contribution of working memory (WM) to children's (N = 471) 2nd language (L2) reading and language acquisition was best accounted for by processing efficiency at a phonological level and/or by executive processes independent of phonological processing. Elementary school children (Grades 1, 2, & 3) whose…

Some children with autism demonstrate poor nonword repetition--a deficit considered to be a psycholinguistic marker of specific language impairment (SLI). The present study examined whether there is an SLI subtype among children with autism. We compared the language abilities of children with SLI (n = 34, M age = 11;10 S.D. = 2;3), and children…

An infant's ability to process auditory signals presented in rapid succession (i.e. rapid auditory processing abilities [RAP]) has been shown to predict differences in language outcomes in toddlers and preschool children. Early deficits in RAP abilities may serve as a behavioral marker for language-based learning disabilities. The purpose of this…

Reviews the logic of neuropsychological inference in the context of connectionist modeling, focusing on the inference from double dissociation to modularity of function. Argues that connectionism appears to create no additional problems for the traditional neuropsychological approach. (50 references) (MDM)

Discusses connectionist models of two subcomponents of the spelling process that, internally, blur modular boundaries, and that explain, rather than describe, the relevant neuropsychological evidence. The competitive queuing spelling model gives a promising account of the characteristics of graphemic buffer disorder. (76 references) (MDM)

Connectionist (parallel distributed processing) modeling provides a new way to approach the neurological study of language. This method focuses on the interplay between a computational model and the appropriate neurological, neuropsychological, and speech and language data, couched in connectionist mechanisms that map naturally to what is known of…

Verb production is notoriously difficult for individuals with Broca's aphasia, both at the word and at the sentence level. An intriguing question is at which level in the speech production these problems arise. The aim of the present study is to identify the functional locus of the impairment that results in verb production deficits in Broca's…

Discusses connectionist techniques that can be used for modeling perception, memory, and language processing, concentrating on a class of network with dual-weight connections in which each connection has both short- and long-term weight and describes a novel architecture in which the short- and long-term weights are independent. (45 references)…

Examines Nickels's claim that interactive models of lexical access in speech production cannot account for naming data from a group of anomic patients. This paper reiterates that the behavior of connectionist models is not easily predictable without running the appropriate simulations, and discusses the role of frequency in lexical access in…

Purpose: There is a substantial minority of children for whom lexical retrieval problems impede the normal pattern of language development and use. These problems include accurately producing the correct word even when the word's meaning is understood. Such problems are often referred to as "word-finding difficulties" (WFDs). This article examines…
