Contextualised retrieval practice: the effect of context type and working memory capacity on word retention

The present study on intentional retrieval practice compared the benefits of presenting words in either informative or uninformative sentence contexts. Participants first studied a list of English words with their translations. Then, they were all exposed to half of the words with informative sentences containing meaning clues in the Context Inference (CI) condition and half with uninformative sentences devoid of such clues in the Memory Retrieval (MR) condition as part of retrieval-based practising. Participants were required to type the L1 translation for each word presented using a mobile application. Data were collected by both form-recall and meaning-recall tests immediately afterwards and then a week later. In addition, this study focused on the relationship between working memory capacity (WMC) and word retention in these two conditions to explore the suggestion that individuals may benefit differently from retrieval practices. Although the results showed that both conditions contributed to word retention, the MR condition was significantly more effective than the CI condition for the participants' long-term retention. Further, the results revealed an overall positive effect of WMC on word retention in both conditions, with high-WMC individuals achieving higher retention scores than low-WMC individuals. However, this effect was not modulated by the type of context condition.
