چکیده

Children can determine the meaning of a new word from hearing it used in a familiar context—an ability often referred to as fast mapping. In this paper, we study fast mapping in the context of a general probabilistic model of word learning. We use our model to simulate fast mapping experiments on children, such as referent selection and retention. The word learning model can perform these tasks through an inductive interpretation of the acquired probabilities. Our results suggest that fast mapping occurs as a natural consequence of learning more words, and provides explanations for the (occasionally contradictory) child experimental data.

Word Learning in the Wild: What Natural Data Can Tell Us

When a child first begins to acquire a lexicon, the sources of word-meanings must be available from the situational context. However, it has been argued that the situational availability of the meanings of relational terms, such as verbs, is lower than that of whole-object labels, such as nouns. In this paper, we present a corpus of child-directed language, paired with situational descriptions,...

Online Processing is Essential for Learning: Understanding Fast Mapping and Word Learning in a Dynamic Connectionist Architecture

The acquisition of word meaning is often partially attributed to fast mapping. However, recent research suggests that fast mapping and word learning may represent distinct components of language acquisition. Here we examine their interaction with a Hebbian Normalized Recurrence Network, a connectionist architecture that captures both online processing and long-term statistical learning. After t...

The Effect of Mnemonic and Mapping Techniques on L2 Vocabulary Learning

The present study investigated the effects of selected presentation techniques including the keyword method, the peg word method, the loci method, argument mapping, concept mapping and mind mapping on L2 vocabulary comprehension and production. To this end, a sample of 151 Iranian female students from a public pre-university school in Islam Shahr was selected. They were assigned to six groups. ...

The Role of Contextual Repetition During Fast Mapping on Word Learning

Recent research suggests that children’s ability to learn words via fast mapping is strongly related to the attentional demands of the task. Here we explore whether lowering the attentional demands during the initial fast mapping task facilitates word learning. Three-year-old children completed fast mapping and test trials using a touch screen computer. For half of the children, the non-targets...

Not so fast: hippocampal amnesia slows word learning despite successful fast mapping.

The human hippocampus is widely believed to be necessary for the rapid acquisition of new declarative relational memories. However, processes supporting on-line inferential word use ("fast mapping") may also exercise a dissociable learning mechanism and permit rapid word learning without the hippocampus (Sharon et al. (2011) Proc Natl Acad Sci USA 108:1146-1151). We investigated fast mapping in...
