چکیده

The paper investigates the morphological impact of quantitative properties of lexical and sublexical structures in the decomposition of morphologically complex words by means of an activation-based simulation. A complex nucleus of blind-to-semantics relationships turns out to allow the emergence of proto-morphological representations and to provide a cognitively efficient route to complex word decomposition. A computational account of how this bundle of information is handled with in the lexical processing of complex pseudo-words is provided. The model is tested against an edit-distance algorithm and a non-word similarity rating task performed by a group of native speakers. RÉSUMÉ. L’article analyse l’impact morphologique des propriétés quantitatives des structures lexicales et sous-lexicales dans la décomposition de mots morphologiquement complexes en faisant appel à une simulation basée sur des états d’activation. Nous observons qu’il existe un noyau complexe de relations extra-sémantiques capable d’activer des représentations protomorphologiques et de canaliser efficacement la décomposition des mot complexes. Nous proposons un modèle de manipulation de ce noyau d’information dans l’élaboration lexicale de pseudo-mots complexes. Le modèle est testé par rapport à un algorithme de distance d’édition et à des jugements sur la similarité de mots fournis par des locuteurs natifs.

Lexical and Sublexical Units in Speech Perception

Saffran, Newport, and Aslin (1996a) found that human infants are sensitive to statistical regularities corresponding to lexical units when hearing an artificial spoken language. Two sorts of segmentation strategies have been proposed to account for this early word-segmentation ability: bracketing strategies, in which infants are assumed to insert boundaries into continuous speech, and clusterin...

A Dual-Route Approach to Orthographic Processing

In the present theoretical note we examine how different learning constraints, thought to be involved in optimizing the mapping of print to meaning during reading acquisition, might shape the nature of the orthographic code involved in skilled reading. On the one hand, optimization is hypothesized to involve selecting combinations of letters that are the most informative with respect to word id...

Extracting salient sublexical units from written texts: “Emophon,” a corpus-based approach to phonological iconicity

A GROWING BODY OF LITERATURE IN PSYCHOLOGY, LINGUISTICS, AND THE NEUROSCIENCES HAS PAID INCREASING ATTENTION TO THE UNDERSTANDING OF THE RELATIONSHIPS BETWEEN PHONOLOGICAL REPRESENTATIONS OF WORDS AND THEIR MEANING: a phenomenon also known as phonological iconicity. In this article, we investigate how a text's intended emotional meaning, particularly in literature and poetry, may be reflected a...

A third route for reading? Implications from a case of phonological dyslexia.

Models of reading in the neuropsychological literature sometimes only include two routes from print to sound, a lexical semantic route and a sublexical phonological route. Other researchers hypothesize an additional route that involves a direct connection between lexical orthographic representations and lexical phonological representations. This so-called 'third route' has been invoked to accou...

Developmental changes in the neural influence of sublexical information on semantic processing.

Functional magnetic resonance imaging (fMRI) was used to examine the developmental changes in a group of normally developing children (aged 8-12) and adolescents (aged 13-16) during semantic processing. We manipulated association strength (i.e. a global reading unit) and semantic radical (i.e. a local reading unit) to explore the interaction of lexical and sublexical semantic information in mak...
