This study examined the impact of various degenerative dementias on access to semantic knowledge and the status of semantic representations. Patients with semantic dementia, primary progressive aphasia, and Alzheimer's disease were compared with elderly controls on tasks of category and letter fluency, with number of words generated, mean lexical…

This paper examines the semantic associations of words found in the business lexical environment by using a one-million word corpus of both spoken and written Business English. The key method of analysis is that of semantic prosody or semantic association; the notion that words associate with collocates that are themselves related, often either…

Many students with autism spectrum disorders show good decoding combined with poor comprehension. Twenty adolescent students with autism spectrum disorders participated in a study concerning the effects of three kinds of facilitation on reading comprehension. In a within-subjects design, each students read passages under four conditions: answering…

The study examined children and adolescents' ability to improve root spelling in Hebrew words by paying attention to phonological, semantic and orthographic properties of priming roots. One hundred and fifty 8, 9, 10, 11 and 15-year olds were administered two spelling tests in Hebrew. The same 40 target words were used in both tests, each word…

Recent developments of e-learning specifications such as Learning Object Metadata (LOM), Sharable Content Object Reference Model (SCORM), Learning Design and other pedagogy research in semantic e-learning have shown a trend of applying innovative computational techniques, especially Semantic Web technologies, to promote existing content-focused…

When the subject of scientific analysis is learning, the research needs to be anchored in various nonmonolithic pillars. Several disciplines require a common ground of convergence. An objective observer of the domain can easily conclude that semantic e-learning brings together the three different worlds of learners, pedagogues and technologists.…

This study investigates the role of the temporal lobes in levels-of-processing tasks (phonetic and semantic encoding) according to the nature of recall tasks (free and cued recall). These tasks were administered to 48 patients with unilateral temporal epilepsy (right ''RTLE''=24; left ''LTLE''=24) and a normal group (n=24). The results indicated…

This article is concerned with the correspondence conditions that hold between certain semantic relations--including part-whole relations, possession, location, and the semantic features [+- animate] or [+- count]--and certain syntactic structures including genitives and relative clauses. The objective is to determine the extent to which these…

Adults learned the meanings of rare words (e.g., gloaming) and then made meaning judgments on pairs of words. The 1st word was a trained rare word, an untrained rare word, or an untrained familiar word. Event-related potentials distinguished trained rare words from both untrained rare and familiar words, first at 140 ms and again at 400-600 ms…

Background: The aim of this study was to examine the effects of familiarity of depicted persons and environments in recognition of photographs for pupils with different degrees of intellectual disability (ID). Method: Forty-five pupils with ID participated. Results: An interaction effect between the two variables, person and environment, was found…

Our claim is that semantic metadata are required to allow a real reusing and assembling of learning objects. Our system is based on three models used to describe the domain, learners, and learning objects. The learning object model is inspired from knowledge representation proposals. A learning object can be reused directly or can be combined with…

Until recently most models of word recognition have assumed that semantic effects come into play only after the identification of the word in question. What little evidence exists for early semantic effects in word recognition has relied primarily on priming manipulations using the lexical decision task, and has used visual stimulus presentation.…

Navajo and Quechua, both languages with a highly complex morphology, provide intriguing insights into the acquisition of inflectional systems. The development of the verb in the two languages is especially interesting, since the morphology encodes diverse grammatical notions, with the complex verb often constituting the entire sentence. While the…

In many areas of language acquisition, researchers have suggested that semantic generality plays an important role in determining the order of acquisition of particular lexical forms. However, generality is typically confounded with the effects of input frequency and it is therefore unclear to what extent semantic generality or input frequency…

Properties of the input, such as raw frequency and syntactic diversity, have been shown to play a role, to different extents, in the acquisition of nouns and verbs. This study investigated the relationship between three properties of the input (input frequency, syntactic diversity, and variety in noun-type co-occurrence) and age of acquisition of…
