Contrast in natural language concepts: An exemplar-based approach
نویسندگان
چکیده
We examine the influence of contrast categories on the internal graded membership structure of natural language categories. To this end we contrast two exemplar models in their account of typicality: According to the GCM, typicality is the summed similarity towards all category members. According to the SDGCM, typicality is determined by both the summed similarity towards all category members and the summed dissimilarity towards members of contrast categories. For five animal categories, we contrast the SD-GCM and the GCM in their account of typicality. Results indicate that the internal category structure can indeed be co-determined by dissimilarity towards potential contrast categories.

Categorization of novel stimuli in well-known natural concepts: a case study.
In this study, we investigated to what extent exemplar-based and prototype predictors can be applied to predicting categorization in natural language concepts. Participants categorized novel tropical foods into two well-known natural language concepts: fruits and vegetables. The results indicate that both the prototype predictors and the exemplar predictors contribute significantly in accountin...
متن کاملExemplar Dynamics and Sound Merger in Language
We develop a model of phonological contrast in natural language. Specifically, the model describes the maintenance of contrast between different words in a language, and the elimination of such contrast when sounds in the words merge. An example of such a contrast is that provided by the two vowel sounds i and e, which distinguish pairs of words such as pin and pen in most dialects of English. ...
متن کاملPrototype and Exemplar-Based Information in Natural Language Categories
Two experiments are reported in which four dependent variables; typicality ratings, response times, category-naming frequencies, and exemplar-generation frequencies of natural language concepts, were predicted by two sorts of prototype predictors and by an exemplar predictor related to Heit and Barsalou’s (1996) instantiation principle. In the first experiment, the exemplar predictor was compar...
متن کاملVowel Discrimination by English, French and Turkish Speakers: Evidence for an Exemplar-Based Approach to Speech Perception
Recent studies of speech perception have shown that speakers retain significant amounts of the phonetic detail of heard speech providing strong evidence for an exemplar-based model of the representation of speech sounds. This does not preclude the existence of a feature-based model as well; indeed many theories of speech perception advocate a feature- or contrast-based model for the discriminat...
متن کاملImproving Exemplar-based Image Completion methods using Selecting the Optimal Patch
Image completion is one of the subjects in image and video processing which deals with restoration of and filling in damaged regions of images using correct regions. Exemplar-based image completion methods give more pleasant results than pixel-based approaches. In this paper, a new algorithm is proposed to find the most suitable patch in order to fill in the damaged parts. This patch selection ...
