Lexical access was examined in English-Spanish bilinguals by monitoring eye fixations on target and lexical competitors as participants followed spoken instructions in English to click on one of the objects presented on a computer (e.g., "Click on the beans"). Within-language lexical competitors had a phoneme onset in English that was shared with…

This study longitudinally investigated developmental changes in the frame of reference used by children in their gestures and speech. Fifteen children, between 4 and 6 years of age, were asked once a year to describe their route home from their nursery school. When the children were 4 years old, they tended to produce gestures that directly and…

Using data on the pattern of occurrence of words embedded in the polysyllabic words of the English vocabulary, argues that recognition and segmentation of continuous speech appear to be based on competition between lexical hypotheses. It is concluded that lexical competition is an essential component of models of continuous speech recognition. (53…

Reviews the logic of neuropsychological inference in the context of connectionist modeling, focusing on the inference from double dissociation to modularity of function. Argues that connectionism appears to create no additional problems for the traditional neuropsychological approach. (50 references) (MDM)

Discusses connectionist models of two subcomponents of the spelling process that, internally, blur modular boundaries, and that explain, rather than describe, the relevant neuropsychological evidence. The competitive queuing spelling model gives a promising account of the characteristics of graphemic buffer disorder. (76 references) (MDM)

Discusses two naming experiments in which it was shown that response times for morphologically structured pseudowords are faster than those for orthographically matched controls. Argues that the results, which are consistent with those obtained in lexical decision tasks with morphologically structured pseudowords, provide support for compositional…

Discusses connectionist techniques that can be used for modeling perception, memory, and language processing, concentrating on a class of network with dual-weight connections in which each connection has both short- and long-term weight and describes a novel architecture in which the short- and long-term weights are independent. (45 references)…

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…

Reviews recent research on English place assimilation (e.g., "sweet" articulated as "sweep" in the environment "sweet boy"), evaluating an account of variation in terms of abstract, underspecified lexical form representations. A hybrid account is proposed where abstract lexical representations can be contacted directly by varying phonetic forms.…

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…

Reviews research that supports the view that readers strip prefixed words of their prefix and lexically assess the words on the basis of their stem. An experiment using real and nonword stems found that nonwords that are considered to be stem morphemes are treated as being more wordlike than those that are not. (36 references) (MDM)

Summarizes the results of Finnish studies dealing with single-word experiments with aphasics as well as lexical decisions and eye-movement registration tests performed on normals. It then proposes a processing model for Finnish nouns, Stem Allomorph/Inflectional Decomposition (SAID), which predicts that both inflected and productive derived forms…

Describes a connectionist model, using a simple recurrent network trained on a phoneme prediction task, that accounts for the child's ability to identify word boundaries. The model shows that aspects of linguistic structure that are not overtly marked in the input can be derived by efficiently combining multiple probabilistic cues. (Author/MSE)
