The mutual exclusivity (ME) assumption is proposed to facilitate early word learning by guiding infants to map novel words to novel referents. This study assessed the emergence and use of ME to both disambiguate and retain the meanings of novel words across development in 18-month-old monolingual and bilingual children (Experiment 1; N = 58), and…

Cross-situational word learning (XSWL) tasks present multiple words and candidate referents within a learning trial such that word-referent pairings can be inferred only across trials. Adults encode fine phonological detail when two words and candidate referents are presented in each learning trial (2 × 2 scenario; Escudero, Mulak, & Vlach,…

This study investigated the effects of two cognitive strategies, rote memorization and semantic mapping, on L2 vocabulary acquisition. Thirty-eight intermediate female EFL learners divided into two experimental groups participated in this study. Each experimental group used one of the strategies for vocabulary acquisition. After the four-month…

Heritage language speakers struggle in European classrooms with insufficient material provided for second language (SL) learning and assessment. Considering the amount of instruments and pertinent studies in English SL, immigrant students are better prepared than their peers in Romance language settings. This study investigates how factors such as…

To investigate the effects of semantic mapping, thematic clustering, and notebook keeping on L2 vocabulary recognition and production, four groups of intermediate level learners in an EFL institute in Zanjan, Iran participated in the study. Three experimental groups consisted of semantic mapping, semantic feature analysis, and vocabulary notebook…

In 3 experiments, 9-month-old infants' expectations for what distinct count noun labels refer to were investigated. In Experiment 1, a box was opened to reveal 2 objects inside during familiarization: either 2 identical objects or 2 different objects. Test trials followed the same procedure, except before the box was opened, the contents were…

Assessed word-learning skills of 19 deaf/hard-of-hearing preschoolers either with novel mapping strategy to learn new words, or after minimal exposure when reference was explicitly established. Found that 11 children were able to learn words in both contexts, 5 only in the second, and 2 in neither. The latter 7 children eventually were able to…

Children improve at word learning during the 2nd year of life--sometimes dramatically. This fact has suggested a change in mechanism, from associative learning to a more referential form of learning. This article presents an associative exemplar-based model that accounts for the improvement without a change in mechanism. It provides a unified…

Many authors have argued that word-learning constraints help guide a word-learner's hypotheses as to the meaning of a newly heard word. One such class of constraints derives from the observation that word-learners of all ages prefer to map novel labels to novel objects in situations of referential ambiguity. In this paper I use eye-tracking to…

First-semester Spanish students were encouraged to acquire vocabulary through small- and large-group oral activities plus semantic mapping. A second group participated in similar oral activities but did not perform semantic mapping. A comparison of the two groups suggests a trend toward the effectiveness of semantic mapping as a strategy that…

Ways in which semantic mapping can be used for general vocabulary development, as a prewriting and prereading activity, as a postreading activity, and as a study skill strategy are presented in this teaching guide. The first two sections provide an introduction to semantic mapping, and outline the three most common uses of semantic mapping as an…
