The Interplay of Cross-Situational Word Learning and Sentence-Level Constraints
A variety of mechanisms contribute to word learning. Learners can track co-occurring words and referents across situations in a bottom-up manner (cross-situational word learning, CSWL). Equally, they can exploit sentential contexts, relying on top-down information such as verb-argument relations and world knowledge, offering immediate constraints on meaning (word learning based on sentence-leve...
متن کاملSentence Processing Mechanisms Influence Cross-Situational Word Learning
Word learning has traditionally examined separately the role of constraints provided by the visual context (e.g. crosssituational learning) and the linguistic context (e.g. syntactic bootstrapping). We suggest that the combined investigation of these learning scenarios is important: Firstly, to determine whether cross-situational word learning applies when words are presented in sentences and, ...
متن کاملAdaptive Constraints and Inference in Cross-Situational Word Learning
Previous research shows that human learners can acquire word-referent pairs over a short series of individually ambiguous situations each containing multiple words and referents (Yu & Smith, 2007). In this kind of cross-situational statistical learning based on the repeated co-occurrence of words with their intended referents, the application of principles such as mutual exclusivity and contras...
متن کاملMore Naturalistic Cross-situational Word Learning
Previous research has found that people can use word-object co-occurrences from ambiguous situations to learn word meanings (e.g., Yu & Smith, 2007). However, most studies of cross-situational learning present an equal number of words and objects, which may simplify the problem by, for example, encouraging learners to use assumptions such as each word going with one object. This paper presents ...
متن کاملCross-situational word learning in aphasia.
Human learners can resolve referential ambiguity and discover the relationships between words and meanings through a cross-situational learning (CSL) strategy. Some people with aphasia (PWA) can learn word-referent pairings under referential uncertainty supported by online feedback. However, it remains unknown whether PWA can learn new words cross-situationally and if such learning ability is s...
