Mutual Exclusivity and Vocabulary Structure
The words that children learn can be characterized as a semantic network, with links connecting related words. Recent analyses have shown these networks to have smallworld structure, with a few highly-connected hub words facilitating short paths between otherwise distant words. This structure contributes to network robustness, and differences in structure can predict differences in language lea...
متن کاملMutual Exclusivity 1 Running head : MUTUAL EXCLUSIVITY IN AUTISM
While there is ample evidence that children treat words as mutually exclusive, the cognitive basis of this bias is widely debated. We focus on the distinction between pragmatic and lexical constraints accounts. High-functioning children with autism spectrum disorders (ASD) offer a unique perspective on this debate, as they acquire substantial vocabularies despite impoverished social-pragmatic s...
متن کاملCharacterizing linguistic structure with mutual information.
We explore mutual information (MI) as a means of characterizing linguistic statistical structure. The MI between two linguistic tokens x and y is the degree to which seeing x helps us anticipate the occurrence of y. We computed MI between words in 595 samples of written text in 25 languages. Our analyses indicate that MI dependencies do not extend beyond a range of five words. Moreover, the sim...
متن کاملCross-situational Word Learning Respects Mutual Exclusivity
Learners are able to infer the meanings of words by observing the consistent statistical association between words and their referents, but the nature of the learning mechanisms underlying this process are unknown. We conducted an artificial cross-situational word learning experiment in which either words consistently appeared with multiple objects (extra object condition) or objects consistent...
متن کاملMutual Exclusivity Revisited - When Pragmatics overrides Novelty
Children typically apply a novel label to a novel object, rather than to a familiar object; a phenomenon called Mutual Exclusivity (Markman et al., 2003). A recent explanation is that children tend to associate novel stimuli together (Horst et al., 2011). We show that pragmatic factors may override novelty. In our study two-year-old children first played with a novel object together with E1. Th...
