Two experiments were conducted to investigate the role of gestures on novel word learning in preschoolers. In Study 1, 20 children at the average age of 4;9 years were given novel words under 3 conditions: with support of iconic gestures; arbitrary gestures; no gestures, exemplifying a within-subject design. Results indicate scaffolding effects of both types of gestures in comparison to the control condition. No indication of gesture type effects could be observed even in children who were old enough to understand the iconicity of iconic gestures. Study 2 was implemented to further test the scaffolding effect of gestures vs. no gestures in children with SLI (n = 20) — but this time only iconic gestures were used. A between-subjects design was followed, using matched groups. Slow mapping was observed in addition to fast mapping within a 5-week-intervention period. Results confirm the scaffolding effect of iconic gestures on slow mapping in the clinical sample.

Previous studies have indicated that bilingualism may facilitate lexical learning in adults. The goals of this research were (i) to examine whether bilingual influences on word learning diverge for phonologically-familiar and phonologically-unfamiliar novel words, and (ii) to examine whether increased phonological memory capacity can account for bilingual effects on word learning. In Experiment 1, participants learned phonologically-familiar novel words that were constructed using the phonemes of English – the native language for all participants. In Experiment 2, participants learned phonologically-unfamiliar novel words that included non-English phonemes. In each experiment, bilingual adults were contrasted with two groups of monolingual adults: a high memory-span monolingual group (that matched bilinguals on phonological memory performance) and a low-span monolingual group. Results showed that bilingual participants in both experiments outperformed monolingual participants, both high-span and low-span. High-span monolinguals outperformed low-span monolinguals when learning phonologically-unfamiliar novel words, but not when learning phonologically-familiar novel words. The findings suggest that the bilingual advantage for novel word learning is not contingent on the phonological properties of novel words, and that phonological memory capacity as measured here cannot account for the bilingual effects on learning.

This study compares homonym learning to novel word learning by three- to four-year-old children to determine whether homonyms are learned more rapidly or more slowly than novel words. In addition, the role of form characteristics in homonym learning is examined by manipulating phonotactic probability and word frequency. Thirty-two children were exposed to homonyms and novel words in a story with visual support and learning was measured in two tasks: referent identification; picture naming. Results showed that responses to homonyms were as accurate as responses to novel words in the referent identification task. In contrast, responses to homonyms were more accurate than responses to novel words in the picture-naming task. Furthermore, homonyms composed of common sound sequences were named more accurately than those composed of rare sound sequences. The influence of word frequency was less straightforward. These results may be inconsistent with a one-to-one form–referent bias in word learning.

In the present study, we examined the effect of speaker certainty on word-learning performance in English-speaking monolingual (MAge = 6.40) and Spanish–English bilingual (MAge = 6.58) children. No group differences were observed when children learned novel words from a certain speaker. However, bilingual children were more willing to learn novel words from an uncertain speaker than their monolingual peers. These findings indicate that language experience influences how children weigh cues to speaker credibility during learning and suggest that children with more diverse linguistic backgrounds (i.e., bilinguals) are less prone to prioritizing information based on speaker certainty.

Purpose The authors of this study examined whether the type and number of word-learning cues affect how children infer and retain word-meaning mappings and whether the use of these cues changes with age. Method Forty-eight 18- to 36-month-old children with typical language participated in a fast-mapping task in which 6 novel words were presented with 3 types of cues to the words' referents, either singly or in pairs. One day later, children were tested for retention of the novel words. Results By 24 months of age, children correctly inferred the referents of the novel words at a significant level. Children retained the meanings of words at a significant rate by 30 months of age. Children retained the first 3 of the 6 word-meaning mappings by 24 months of age. For both fast mapping and retention, the efficacy of different cue types changed with development, but children were equally successful whether the novel words were presented with 1 or 2 cues. Conclusion The type of information available to children at fast mapping affects their ability to both form and retain word-meaning associations. Providing children with more information in the form of paired cues had no effect on either fast mapping or retention.

Purpose The goal of this research was to examine whether phonological familiarity exerts different effects on novel word learning for familiar versus unfamiliar referents and whether successful word learning is associated with increased second-language experience. Method Eighty-one adult native English speakers with various levels of Spanish knowledge learned phonologically familiar novel words (constructed using English sounds) or phonologically unfamiliar novel words (constructed using non-English and non-Spanish sounds) in association with either familiar or unfamiliar referents. Retention was tested via a forced-choice recognition task. A median-split procedure identified high-ability and low-ability word learners in each condition, and the two groups were compared on measures of second-language experience. Results Findings suggest that the ability to accurately match newly learned novel names to their appropriate referents is facilitated by phonological familiarity only for familiar referents but not for unfamiliar referents. Moreover, more extensive second-language learning experience characterized superior learners primarily in one word-learning condition: in which phonologically unfamiliar novel words were paired with familiar referents. Conclusions Together, these findings indicate that phonological familiarity facilitates novel word learning only for familiar referents and that experience with learning a second language may have a specific impact on novel vocabulary learning in adults.

Novel Word Learning

Adults regularly use word-gesture combinations in communication, and meaningful gestures facilitate word learning. However, it is not clear if this benefit of gestures is due to the speaker’s movement increasing the listener’s attention or if it needs to be a meaningful gesture, if the difficulty of the task results in disparate reliance on gestures, and if word classes are differentially affected by gestures. In the present research, participants were measured on their novel word learning across four gesture conditions: meaningful gesture, beat gesture, nonsense gesture, and no gesture with extended training (Study 1, n = 139) and brief training (Study 2, n = 128). Overall, meaningful gestures and high frequency words led to the highest word learning accuracy. This effect of word frequency did not hold true for beat gestures after brief training suggesting that adding rhythmic information — if not adding semantic information — may detract from word learning. This research highlights the importance of considering task difficulty when analyzing the effects of gestures.

Abstract This study investigated how bilingual experience alters neural mechanisms supporting novel word learning. We hypothesised that novel words elicit increased semantic activation in the larger bilingual lexicon, potentially stimulating stronger memory integration than in monolinguals. English monolinguals and Spanish–English bilinguals were trained on two sets of written Swahili–English word pairs, one set on each of two consecutive days, and performed a recognition task in the MRI-scanner. Lexical integration was measured through visual primed lexical decision. Surprisingly, no group difference emerged in explicit word memory, and priming occurred only in the monolingual group. This difference in lexical integration may indicate an increased need for slow neocortical interleaving of old and new information in the denser bilingual lexicon. The fMRI data were consistent with increased use of cognitive control networks in monolinguals and of articulatory motor processes in bilinguals, providing further evidence for experience-induced neural changes: monolinguals and bilinguals reached largely comparable behavioural performance levels in novel word learning, but did so by recruiting partially overlapping but non-identical neural systems to acquire novel words.
