Previous studies have examined the familiarity, transparency, and context in understanding of idioms in children and adolescents. The effects of variations in the level of idiom transparency and degree of contextual support were discussed. In general adolescent group outperformed in comparison to children. Whereas the present study was designed to examine the effect of context on interpretation of familiar idioms in typical school aged children, ages 5 and 9. A total of 30 participants will be included in this study. It is hypothesized that 9-year-old children will be able to interpret familiar idioms within context, but five year olds will not. Additionally, the study aims to show that girls of all ages will be better at interpreting familiar idioms than boys, regardless of whether or not context is provided. The hypotheses will be tested for significance with appropriate analysis of variance (ANOVA) and independent t-sample test. The results of this study will be discussed with the findings of past researchers.
