Animals, foods, and household items—oh my! Evidence of 24-30-month-old children’s increasing flexibility in word learning from naturalistic data

At 18 months of age, children frequently generalize (and overgeneralize) novel objects’ labels by shape (Landau et al., 1988). However, data from laboratory studies using ostensive word-learning paradigms indicate that, by three years of age, children generalize the labels of novel objects depending...
