The hypothesis that overall-similarity relations structure both adults' and children's classifications of heterogeneous objects (objects that differ in a variety of ways) was supported in two experiments. When objects varied simultaneously on many dimensions, adults and children constructed classifications that maximized within-category similarity…

Physics learning involves a change in the habitual perception of the everyday world. In order to describe the real world scientifically, an individual must develop perception and cognition capable of reconstructing the world from raw sensory data and incorporating acquired knowledge of the scientific community. The introductory physics student…

Investigates comprehension of metaphoric compounds. The study asked children and adults to identify referents of various types of these compounds. Findings reveal that 5-year-olds outperformed 3-year-olds but performed significantly less well than adults and that 3-year-olds did not generally interpret the compounds literally. (37 references)…

Two experiments examine whether the encoding of location meets criteria defining an automatic process. Automatic processes are not expected to show developmental changes beyond an early age. They appear to be unrelated to intelligence level and unaffected by instructions. Results support Hasher and Zack's automaticity hypothesis. (RWB)
