Background: The implicit learning deficit hypothesis claims that impaired implicit learning underlies deficits in social-communicative abilities associated with developmental language disorder (DLD). However, previous research testing this hypothesis revealed inconsistent results and largely used process-impure sequential learning tasks. Aims:…

Children with developmental language disorder (DLD) have significant deficits in language ability that cannot be attributed to neurological damage, hearing impairment, or intellectual disability. The symptoms displayed by children with DLD differ across languages. In English, DLD is often marked by severe difficulties acquiring verb inflection.…

Do children learn a new word by tracking co-occurrences between words and referents across multiple instances ("cross-situational learning" models), or is word-learning a "one-track" process, where learners maintain a single hypothesis about the possible referent, which may be verified or falsified in future occurrences…

The aim was to evaluate conceptual scoring of lexical organization in bilingual children with language impairment (BLI) and to compare BLI performance with monolingual children with language impairment (MLI). Word associations were assessed in 15 BLI and 9 MLI children. BLI were assessed in Arabic and Swedish, MLI in Swedish only. A number of…

Using the blocked-translation paradigm with healthy participants, we examined Crutch and Warrington's hypothesis that concrete and abstract concepts are organized by distinct principles: concrete concepts by semantic similarities and abstract ones by associations. In three experiments we constructed two types of experimental blocking (similar…

The ability to form associations between words and objects rapidly with a short amount of exposure is a marker of more proficient word learners in typically developing (TD) infants. Investigating the underlying mechanisms for how words are associated with objects is necessary for understanding early word learning in the TD population as well as in…

Purpose: To examine the degree of convergence in word association responses produced by bilingual children with primary language impairment (PLI) in relation to bilingual age peers. Method: Thirty-seven Spanish-English bilingual children with PLI, 37 typically developing (TD) controls, and a normative sample of 112 children produced associations…

This article reports on a study on learning new and relearning forgotten words of French as a foreign language in young (mean age 22.4), middle-aged (mean age 50.3), and elderly speakers (mean age 76.0). The three age groups performed similarly on relearning old words, but the younger learners were significantly better at learning new words. Data…

Background: Much evidence has accumulated to indicate memory deficits in children with specific language impairment. However, most research has focused on working memory impairments in these children. Less is known about the functioning of other memory systems in this population. Aims: This study examined procedural and declarative memory in young…

The neuropsychological features of the primary progressive aphasia (PPA) syndromes continue to be defined. Here we describe a detailed neuropsychological case study of a patient with a mutation in the progranulin ("GRN") gene who presented with progressive word-finding difficulty. Key neuropsychological features in this case included gravely…

This article for speech language pathologists discusses theories of language learning and use that are consistent with whole language, including lexical contrast, connectionism, schemata, event representations, and parsing. Direct application is made to intervention, and examples of interactions between speech language pathologists and children…
