The Role of Lexical-Semantic Neighborhood in Object Naming: Implications for Models of Lexical Access
The role of lexical-semantic neighborhood is relevant to models of lexical access. Recently it has been claimed that the size of the cohort of activated competitors affects ease of lexical selection in word production as well as the effect of semantically related distractors in picture-word interference tasks. Three experiments are reported in which subjects had to name pictures from large and ...
متن کاملPreferred Lexical Access Route in Persian Learners of English: Associative, Semantic or Both
Background: Words in the Mental Lexicon (ML) construct semantic field through associative and/ or semantic connections, with a pervasive native speaker preference for the former. Non-native preferences, however, demand further inquiry. Previous studies have revealed inconsistent Lexical Access (LA) patterns due to the limitations in the methodology and response categorization. Objectives: To f...
متن کاملA theoretical account of lexical and semantic naming deficits in bilingual aphasia.
PURPOSE The purpose of this study was to examine premorbid language proficiency and lexical and semantic processing deficits in bilingual aphasia and develop a theoretical account of bilingual language processing. METHOD Nineteen Spanish-English patients with bilingual aphasia completed a language use questionnaire (LUQ) and were administered Spanish and English standardized language assessme...
متن کاملTalker Variability in Lexical Access: Evidence from Semantic Priming
It is usually assumed that lexical representations are abstract and devoid of detailed information about various sources of acoustic variability. This assumption is evaluated in this study by examining the effect of talker variability on the access to word meaning in a short-term semantic priming experiment. Prime–target pairs that were semantically related (e.g., king–queen) or unrelated (e.g....
متن کاملAge of acquisition effects in picture naming: evidence for a lexical-semantic competition hypothesis.
In many tasks the effects of frequency and age of acquisition (AoA) on reaction latencies are similar in size. However, in picture naming the AoA-effect is often significantly larger than expected on the basis of the frequency-effect. Previous explanations of this frequency-independent AoA-effect have attributed it to the organisation of the semantic system or to the way phonological word forms...
