Twelve-month-olds' understanding of prior actions and final goals.

Twelve-month-olds were habituated to trials in which a grasping action preceded the holding of an object. Infants recovered looking to test events when a new object was held, but only when this was preceded by prior contact with the object.

Partial knowledge of word meanings: thematic and taxonomic representations.

The type of information (taxonomic or thematic) available at different levels of knowledge was investigated. Following extensive norming to identify taxonomic and thematic associates of low-frequency nouns, participants determined if taxonomic or thematic associates were meaningfully related to target words at three levels of knowledge: target words they correctly defined (known), recognized as familiar (frontier), or mistakenly denied as part of the language (unknown). In another experiment, participants reported which type of relationship (taxonomic or thematic) was preferred.
