Previous research has demonstrated that visual properties of objects can affect shape-based categorization in a novel-name extension task; however, we still do not know how a relationship between visual properties of objects affects judgments in a novel-name extension task. We examined effects of increased visual similarity among the target and…

Using a new paradigm for measuring children's saving behaviors involving two marble games differing in desirability, we assessed whether 3-, 4-, and 5-year-olds saved marbles for future use, saved increasingly on a second trial, saved increasingly with age, and were sensitive to the relative value of future rewards.
