Genetic aspects of verbal mediation in memory

When do children begin to store visually presented information using a speech code? Conrad has shown that at age 6, but not before, children have more difficulty in recalling items whose names rhyme than items whose names do not and concluded that at 6 years of age children begin to store information in memory using verbal labels. Experiment 1, using a technique similar to the one introduced by Conrad, showed that 4-year-old children memorized nonrhyming items better than rhyming ones. Experiment 2 used a different technique. Instead of comparing the performance obtained with 2 series of different items, one with rhyming and the other with nonrhyming names, we have, by using bilingual children, made comparisons within the same series of items. In one language the items had rhyming names and in the other, nonrhyming names. This technique controlled for the intrinsic difficulty of the items. The results of experiment 2 confirmed those obtained in experiment 1. Our conclusion is that 4-year-old children already use a speech code in order to store and organize information in memory.FLWNO
