“ba:y?d” as a persian lexeme is interwoven with modality, a semantic category and therefore has a complicated and thought- provoking semantic nature. this paper uses evidence from persian to investigate the usage of this lexeme and some of its semantic and pragmatic aspects in this language. the results indicate that this lexical category can convey a wide range of modal meanings in different c...

The study investigates the electrophysiological signature for Categorical Perception (CP) of lexical tones. Mandarin level and rising tones are the targets and nonspeech counterparts, using pure tones with the same pitch contours, are synthesized as controls. The results show that in lexical tone condition, across-category deviant elicits Mismatch Negativity (MMN) but within-category deviant do...

Three experiments investigated the impact of five lexical variables (instance dominance, category dominance, word frequency, word length in letters, and word length in syllables) on performance in three different tasks involving word recognition: category verification, lexical decision, and pronunciation. Although the same set of words was used in each task, the relationship of the lexical vari...

To what extent does prior knowledge of a superordinate category facilitate recognition of an instance of that category? In Experiment 1, observers named good and poor exemplars of categories with and without prior presentation of the category name. The test words were either printed in a normal upright position, or the words were rotated 180°. Prior priming with the category name shortened nami...

Psycholinguistic studies suggest that early on children acquire robust knowledge of the abstract lexical categories such as nouns, verbs and determiners (e.g., Gelman & Taylor, 1984; Kemp et al., 2005). Children’s grouping of words into categories might be based on various cues, including the phonological and morphological properties of a word, the distributional information about its surroundi...

Lexical ambiguity is an important source of inefficiency for wide-coverage HPSG parsing. In this paper, we propose a lexical analysis filter which removes unlikely lexical categories. The filter is implemented as a straightforward HMM n-gram POS-tagger, which computes the ’a posteriori’ probability of each lexical category. A lexical category is removed if a competing lexical category is suffic...
