Focuses on Elman's (1990) statistical analyses of the hidden unit activation patterns in his simple recurrent network on sentence prediction, first to highlight the feasibility of such analyses and then to show how connectionist explanations contribute to the development of effective explanatory theories. Argues for the evolutionary nature of…

Presents a model of high-dimensional context space, the Hyperspace Analogue to Language (HAL), with a series of simulations modelling human empirical results. Proposes that HAL's context space can be used to provide a basic categorization of semantic and grammatical concepts; model certain aspects of morphological ambiguity in verbs; and provide…

Unlike conventional information retrieval systems, natural language processing (NLP) systems translate queries automatically into the language of the system. This paper discusses the potential impact of NLP on both the indexing and retrieval of text and examines some current NLP projects and systems that have established knowledge bases in narrow…

Examines students' summaries of three lectures. Finds that the percentage, but not the number, of propositions correlated positively with the accuracy scores in the summaries. Suggests that analyses of errors, lexical substitutions, discrepancies in grades, and differences in students' scores for the different lectures revealed interesting results…

Aims to foster discussion of the means by which bilinguals control their two language systems. Proposes an inhibitory control model that embodies the principle that there are multiple levels of control. The model is used to expand the explanation of the effect of category blocking in translation proposed by Kroll and Stewart (1994). (Author/VWL)

We show how emergence offers new explanations for the behaviour of metaphorically-used expressions. Analysis of metaphors in two types of natural language data are combined: detailed analysis of continuous discourse, which offers wealth of context and the possibility of monitoring emergent forms as the discourse unfolds, and computer-assisted…

In the first part of this study, we investigated effects of item and task type on span performance in a group of aphasic individuals with word processing and STM deficits. Group analyses revealed significant effects of item on span performance with span being greater for digits than for words. We also investigated associations between subjects'…

Discourse context may affect comprehension of a word in a text by facilitating lexical access or by facilitating integration of the target concept with the preceding text. In two experiments, we used eye tracking measures to examine contextual influence on the integration of role fillers in scripted narratives. In both experiments, context had an…

In this paper we present a case of "word-meaning deafness," characterised by serious problems in the comprehension of spoken language, whilst repetition and writing words and non-words from dictation are preserved. This performance indicates the impossibility of correctly accessing phonological representation from the semantic representation of…

Previous studies have shown that an aphasic patient (AB) with a semantic short-term memory deficit (STM) had difficulties comprehending and producing sentences with structures that demanded the simultaneous retention of several individual word meanings (Martin & Freedman, 2001a, 2001b; Martin & Romani, 1994; Martin, Shelton, & Yaffee, 1994). The…

In 4 experiments, the authors addressed the mechanisms by which grammatical gender (in Italian and German) may come to affect meaning. In Experiments 1 (similarity judgments) and 2 (semantic substitution errors), the authors found Italian gender effects for animals but not for artifacts; Experiment 3 revealed no comparable effects in German. These…

This study investigated how lexical access in naming tasks (picture naming, naming to open-ended sentences, and naming to category exemplars) might be influenced by different lexical factors during adolescence and adulthood. Participants included 1075 individuals, ranging in age from 12 to 83 years. Lexical factors examined included word frequency…

We introduce a new method of sign language subtitling aimed at young deaf children who have not acquired reading skills yet, and can communicate only via signs. The method is based on: 1) the recently developed concept of "semantroid[TM]" (an animated 3D avatar limited to head and hands); 2) the design, development, and psychophysical evaluation…

Two studies were performed to determine the process used by young children to figure out the meaning of a new word. It was hypothesized that the children would use one of two strategies: (1) ignore the word and wait for more information, or learn only what is unambiguous about it, or (2) make a reasonable but uncertain guess, quickly setting up…

A study examined cognitive processing differences between metaphoric and literal sentences. Thirty-three undergraduate students listened to 96 test sentences (including 48 fillers) that expressed 1 meaning in either a novel or frozen metaphorical or literal form: "The old couch was in love with its new slipcover" (novel), "The old couch was at…
