Description: Studies on the role of speech production on learning have found a memory benefit from production labelled the “Production Effect”. While research with adults has generally shown a robust memory advantage for produced words, children show more mixed results, and the advantage is affected by age, cognitive, and linguistic factors. With adults, the Production Effect is not restricted to the immediate context but also found after a delay. So far, no studies have investigated the effect of delayed recall on the Production Effect with children. Children aged 5-and-6 years old (n=60) participated in two sessions. Children were trained on familiar words and images, which were heard (Listen) or produced aloud (Say). Children then performed a free recall task. One week later, children repeated the recall task and an additional recognition task. At immediate testing, there was a recency effect on words recalled from the different training conditions and a recall advantage for words produced over words heard; however, this no longer held after a 1-week-delay in either the recall or recognition task. Exploratory analysis showed that vocabulary did not predict the Production Effect. Findings indicate that unlike adults, the Production Effect is not as robust in children after a delay.
