Acquired aphasics and dyslexics with even very profound word reading impairments have been shown to perform relatively well on the lexical decision task (e.g., Buchanan, Hildebrandt, & MacKinnon, 1999), but direct contrasts with unimpaired participant's data is often complicated by extremely long reaction times for patient data. The dissociation…

We report a series of neural network models of semantic processing of single English words in the left and the right hemispheres of the brain. We implement the foveal splitting of the visual field and assess the influence of this splitting on a mapping from orthography to semantic representations in single word reading. The models were trained on…

Nonwords created by transposing two "adjacent" letters (i.e., transposed-letter (TL) nonwords like "jugde") are very effective at activating the lexical representation of their base words. This fact poses problems for most computational models of word recognition (e.g., the interactive-activation model and its extensions), which assume that exact…

Four experiments are reported exploring whether distractor pictures activate their phonological properties in the course of speech production. In Experiment 1, participants were presented with two pictures and were asked to name one while ignoring the other. Distractor pictures were phonologically related, semantically related or unrelated to the…

Ellis's target article suggests that language processing is based on frequency and probabilistic knowledge and that language learning is implicit. These findings are consistent with those of SLA researchers working within a variationist framework (e.g., Tarone, 1985; Bayley & Preston, 1996). This paper provides a brief overview of this research…

This third of three articles on the ways in which people formulate their observations presents an analysis of the perspective or attitude dominating the discourse of an interview. The analysis is conducted according to a paradigm that views the speaker as the controller of discourse perspective. The relationships found in the analysis are…

Research on text organization has demonstrated that reading is responsive to the number and complexity of idea units or propositions in a text, and that the capacity of children to recall information is responsive to the relative importance of the idea units. A study was undertaken to examine an extension of these propositions: namely, that…

Research efforts to model speech perception in terms of a processing system in which knowledge and processing are distributed over large numbers of highly interactive--but computationally primative--elements are described in this report. After discussing the properties of speech that demand a parallel interactive processing system, the report…

A computer natural language system called HWIM (Hear What I Mean) is described in this report. Noting that the system accepts either typed or spoken inputs and produces both typed and spoken responses, the report proposes HWIM as an example of a relatively complete language system illustrating how the many components of language processing…

The study described here offers a model of target-context relations in language comprehension. It is based on the hypothesis that the same formal mechanisms that produce cohesion in discourse and texts are critically involved in language comprehension. The model posits that: (1) the comprehension of a target turn is primarily dependent on the…

Describes the "Competition Model" (Bates and MacWhinney, 1982) dealing with second-language sentence processing by bilinguals and research that has further developed theories dealing with the model. (CB)

The purpose of this study was to test a specific hypothesis with regard to how cloze retrieval takes place once semantic constraints are recognized. Results from human subjects and computer simulation suggested that increase in latency between the two- and three-semantic-constraint conditions was not artifactual. (JAZ)

Reviews the theoretical foundations of current-second language acquisition models. Draws upon this research as well as upon various studies of memory and verbal-input processing to present a theoretical model of adult second language comprehension. Discusses the implications of comprehension theory for second-language teaching. (Author/SED)

Examines assumptions about second language acquisition by means of the anatomical model described in Part 1 of the study (see vol. 6, no. 2 of this journal). The analysis shows that the assumptions are rooted in the Direct Method and that they retard learning. Implications for second language instruction are noted. (SED)

Describes a semantic content recognition process based on relatively small sets of context relators, logical relators, phase and state relators, and aspect relators, which are connecting tools in describing meanings in process of concept formation and human communication. Semantic analysis of textual data by computer is tested for feasibility.…
