Three studies examined two-year olds' understanding of novel terms for objects that they are already familiar with under another name. The studies found that the new term was most likely to be treated as a second basic-level name for the category to which the object belonged. (MDM)

Three studies explored 2- to 4-year-olds' ability to categorize objects based on novel underlying causal power. Children saw that a "blicket" would set off a machine and participated in categorization, induction, and association tasks. Results demonstrated that even 2-year-olds easily learn about an object's new causal power and…

Picture-grouping and word-association tasks were used to evaluate the hypothesis that paradigmatic (same form class) word associates are not always categorical and may be a function of the child's understanding of interactive and categorical relations. (SB)

Study concerned with the effects of procedural differences on the classification of geometrical stimuli. (Author)

Examined whether superior recall of items in event-based categorical relations, or "slot fillers," remained when association and typicality were controlled. Found that only children receiving the typical + high association slot-filler list showed significantly better recall than with the taxonomic-coordinate list, with no differences…
