This study investigated whether seeing iconic gestures depicting verb referents promotes two types of generalization. We taught 3- to 4-year-olds novel locomotion verbs. Children who saw iconic manner gestures during training generalized more verbs to novel events ("first-order generalization") than children who saw interactive gestures…

A nap soon after encoding leads to better learning in infancy. However, whether napping plays the same role in preschoolers' learning is unclear. In Experiment 1 (N = 39), 3-year-old habitual and nonhabitual nappers learned novel verbs before a nap or a period of wakefulness and received a generalization test examining word extension to novel…

Children often find it difficult to map verbs to specific referents within complex scenes, often believing that additional features are part of the referents. This study investigated whether 3-year-olds could use iconic gestures to map novel verbs to specific referents. One hundred and twenty children were taught verbs that could be interpreted as…

Generic sentences (e.g., "Birds lay eggs") convey generalizations about entire categories and may thus be an important source of knowledge for children. However, these sentences cannot be identified by a simple rule, requiring instead the integration of multiple cues. The present studies focused on 3- to 5-year-olds' (N = 91) use of…

Examined children's tendency to make argument structure overgeneralization errors. Found that 3- to 8-year-olds were more likely to overgeneralize verbs less familiar to them, supporting the hypothesis that verb usage in particular construction types becomes entrenched over time. As children learn transitivity status of particular verbs, they…
