Control subjects provided significantly more metaphoric accounts of pairings than children with language disorders, regardless of modality.

The present study employs event related potentials (ERPs) to verify the utility of using electrophysiological measures to study developmental questions within the field of language comprehension. Established ERP components (N400 and P600) that reflect semantic and syntactic processing were examined. Fifteen adults and 14 children (ages 8-13)…

Three studies used computer graphics and/or verbal questioning to examine beliefs among children and adults that vision involves input to the eyes (intromission) or emissions from the eye (extramission). Results showed decreases in extramission and increases in intromission beliefs across age. There were more extramission interpretations with…

The study consisted of two experiments. In the first, 32…

Investigated verbal and nonverbal paired associate learning among 8- to 11-year-old Dutch dyslexic children and chronological-age and reading-age controls.
