This article compares three models of morphological storage and processing: (1) the dual-processing model of Pinker, Marcus and others; (2) the connectionist model of Marchman, Plunkett, Seidenberg, and others; and (3) the network model of Bybee and Langacker. Type frequency of a morphological pattern is shown to be important in determining…

The development, use, and initial evaluation of a prototype computer system is described that enables nonspeaking persons with severe disabilities to engage in conversation on broad topics. Features include speech acts selected from a prestored menu and facilities for switching conversational perspectives between speaker and listener. (Contains 53…

A study based on monthly recordings of one bilingual child exposed to English and German suggests that, contrary to earlier research, the acquisition of sociolinguistic rules appears to precede the acquisition of structural rules. The assumption that linguistic sophistication is necessary for children to understand that they are exposed to two…

A review is offered of various bilingual memory studies that have been carried out during the past quarter century. Most of the studies have employed lexical items as the investigative tool, tested outside of a grammatical or semantic context. (Contains 58 references.) (JL)

Three studies compared development of orthographic representations in children learning to read English, French, and Spanish, using nonsense words rhyming with real words, similar in phonology only, or unlike real words. Results are interpreted in terms of the level of phonology represented in the orthographic recognition units being developed by…

The definition of "orthographic neighbors" in word recognition research was analyzed in two experiments using a variety of the three-field technique. Only orthographically related pairs differing from the prime by the third or fourth letter showed inhibitory relatedness effects compared with unrelated word condition. Results suggest…

Three experiments investigated the nature of productive forward linking (from semantics to syntax) and productive reverse linking (from syntax to semantics) in language-impaired children. Found that the normally developing control subjects showed a good use of productive forward and reverse linking, whereas the language-impaired subjects…

Describes a connectionist model accounting for newborn infants' ability to finely discriminate almost all human speech contrasts and the fact that their phonemic category boundaries are identical, even for phonemes outside their target language. The model posits an innately guided learning in which an artificial neural network is stored in a…

Reports language acquisition experiments with simple recurrent networks solving phoneme prediction in continuous phonemic data, which suggests the network output could function as a source for syllable boundary detection. The phoneme prediction network simulates the necessary "bootstrap" to discover syllabic segmentation in unsegmented…

Describes language acquisition processes occurring in a community of interacting agents, in which coordination of joint attention leads to the development of structures, internal and external, that support organized behavior. It is argued that the simulation model demonstrates the plausibility of propositions arising from such processes, and that…

Reports the results of three experiments that used vowel and tone monitoring tasks to investigate the role of tone information in processing Mandarin. (Author/VWL)

Gives a brief characterization of the ways second-language acquisition researchers use the computer to elicit second-language (L2) production data or to record how L2 learners process L2 input. Eight tasks and/or techniques are described. Discusses the use of computer technology in ongoing investigations that pertain to the acquisition of…

Two experiments investigated the effect of kanji morphemic homophony on lexical decision and naming. Effects were examined from both the left-hand and right-hand positions of Japanese two-kanji compound words. The number of homophones affected the processing of compound words in the same way for both tasks. For left-hand kanji, fewer morphemic…

An event-related brain potential experiment was carried out to investigate the temporal relationship between lexical selection and the semantic integration in auditory sentence processing. Participants were presented with spoken sentences that ended with a word that was either semantically congruent or anomalous. Information about the moment in…

The increasingly integrative use of images with language in many different types of texts in electronic and paper media has created an urgent need to go beyond logocentric accounts of literacy and literacy pedagogy. Correspondingly there is a need to augment the genre, grammar and discourse descriptions of verbal text as resources for literacy…
