Propose but verify: fast mapping meets cross-situational word learning.
We report three eyetracking experiments that examine the learning procedure used by adults as they pair novel words and visually presented referents over a sequence of referentially ambiguous trials. Successful learning under such conditions has been argued to be the product of a learning procedure in which participants provisionally pair each novel word with several possible referents and use ...
متن کاملCross-Situational Learning Is Supported by Propose-but-Verify Hypothesis Testing
When we encounter a new word, there are often multiple objects that the word might refer to [1]. Nonetheless, because names for concrete nouns are constant, we are able to learn them across successive encounters [2, 3]. This form of "cross-situational" learning may result from either associative mechanisms that gradually accumulate evidence for each word-object association [4, 5] or rapid propo...
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...
متن کاملCompetitive Processes in Cross-Situational Word Learning
Cross-situational word learning, like any statistical learning problem, involves tracking the regularities in the environment. However, the information that learners pick up from these regularities is dependent on their learning mechanism. This article investigates the role of one type of mechanism in statistical word learning: competition. Competitive mechanisms would allow learners to find th...
