What do children’s errors tell us about the strategies used during a word inferencing task?

Abstract

A vital and often overlooked aspect of word learning is the ability to establish deep semantic knowledge by adjusting and fine-tuning new word meanings as information becomes available. Here we studied differences in children’s ability to update incorrect or incomplete word meanings by studying error types in a word inferencing task. The participants, 45 8- and 9-year-olds, read three sentences that all ended with the same nonsense word and were asked to identify the meaning of the last word. Importantly, the third sentence always provided the most useful information about the word’s meaning. When children made errors, two types of responses were of interest. The first was when children gave a response that ignored the third sentence but fit one or two of the earlier ones. This suggests that the children had failed to update the meaning accurately. The second was when children were given enough information in the three sentences yet said that they were still unable to identify a word meaning. This suggests that the children would not attempt to infer a word when they were unsure of the answer. When controlling for number of correct responses, we found that children with smaller vocabularies were significantly more likely to fail to incorporate the third sentence, whereas children with large vocabularies were more likely to say that they were still unable to identify a meaning. These findings indicate that children with smaller vocabularies may be at risk of incorrectly inferring a new word’s meaning rather than seeking further information to ensure accuracy.
