Several studies have argued that children under the ages of nine or ten years rarely comprehend figurative language and therefore interpret it literally. Cacciari & Levorato (1989). showed that when idioms are presented within a rich informational environment, children are able to grasp the figurative sense at the age of seven, and also that children are less able to produce idioms than to comprehend them. In three experiments involving 264 children (whose age ranged from 6;9 to 11;9), we contrasted this global elaboration hypothesis with a partially alternative one, the acquisition via exposure hypothesis, according to which the frequency of exposure of children to idioms is the main factor explaining their acquisition and production. Results showed that familiarity (i.e. frequency of exposure) plays a minor role and only for children who are not yet able to use contextual information. Familiarity per se does not adequately explain how children acquire a figurative competence. A tentative model is proposed in order to account for figurative competence acquisition.

The current study analyzed the relationship between text comprehension and memory skills in preschoolers. We were interested in verifying the hypothesis that memory is a specific contributor to listening comprehension in preschool children after controlling for verbal abilities. We were also interested in analyzing the developmental path of the relationship between memory skills and listening comprehension in the age range considered. Forty-four, 4-year-olds (mean age = 4 years and 6 months, SD = 4 months) and 40, 5-year-olds (mean age = 5 years and 4 months, SD = 5 months) participated in the study. The children were administered measures to evaluate listening comprehension ability (story comprehension), short-term and working memory skills (forward and backward word span), verbal intelligence and receptive vocabulary. Results showed that both short-term and working memory predicted unique and independent variance in listening comprehension after controlling for verbal abilities, with working memory explaining additional variance over and above short-term memory. The predictive power of memory skills was stable in the age range considered. Results also confirm a strong relation between verbal abilities and listening comprehension in 4- and 5-year-old children.
