title: Lexicalization of idioms in urban fifth graders: a reaction time study.
abstract: Idioms are an important aspect of language that comprises a sizeable portion of our vocabulary. However, lexical access research has largely been limited to understanding how literal words are accessed and processed in the mental lexicon. Adult data show that idioms are quickly accessed from the lexicon and are likely processed as long words [J. Verbal Learn. Verbal Behav. 18 (1979) 523]. The purpose of this study was to examine lexicalization of idioms in a group of school-aged children. Using a phrase classification design, this research tested the Lexical Representation Hypothesis [J. Verbal Learn. Verbal Behav. 18 (1979) 523] in 19 urban fifth graders (5 boys, 14 girls; M age=10.16 years). On a computer, the students classified 54 phrases, including 24 idioms (high, moderate, and low familiarity [J. Speech Hear. Res. 36 (1993) 728]), 24 grammatical control word strings and 6 unrelated foils as either idioms or nonidioms. The idioms were identified with 62% accuracy. Unexpectedly, the boys tended to show higher rates of accuracy than the girls. Response latencies were shorter on the idioms compared to the controls and high familiarity idioms were processed faster than moderate and low familiarity idioms. These findings provide developmental data for lexicalization of idioms and the relationship between lexicalization and familiarity. At the cocnlusion of this articel, the reader will be able to: (1). discuss the various theories of idiom access and processing, (2). discuss how lexical access relates to idiom knowledge in school-aged children, and (3). consider the association between lexical access and familiarity relative to idiom comprehension in school-aged children.
