When memories are reactivated during sleep, they are potentially transformed and strengthened. However, disturbed sleep may make this process ineffective. In a prior study, memories formed shortly before sleep were weakened by auditory stimulation when that stimulation provoked memory reactivation while also disrupting sleep -- a procedure known…

A B S T R A CT Purpose: Retrieval practice has been shown to assist the word learning of children with developmental language disorder (DLD). Although this has been true for learning new verbs as well as new nouns and adjectives, these children's overall verb learning has remained quite low. In this preregistered study, we presented novel verbs in…

The various ways in which forgetting, an inherent component of the human memory process, occurs are essential for understanding cognitive function and memory control. This paper investigates the main categories of forgetting, including retrieval failure, decay, interference, motivated or conscious forgetting, and encoding failures. Retrieval…

Value-directed remembering refers to the tendency to best remember important information at the expense of less valuable information, and this ability may draw on strategic attentional processes. In six experiments, we investigated the role of attention in value-directed remembering by examining memory for important information under conditions of…

Free time in a working memory task often improves the recall performances of the to-be-remembered items. It is still debated whether the free-time effect in working memory is purely proactive, purely retroactive, or both proactive and retroactive. In the present study, we used the single-gap paradigm to explore this question. In Experiment 1, we…

Retrieval practice is an effective strategy to promote long-term retention and learning, but students do not always use it in the most effective ways. Applying various intervention design principles that leverage sociomotivational research, we created an intervention targeted not only at teaching students about the efficacy of retrieval practice,…

Proactive interference (PI) occurs when previously learned memories compete with currently relevant information. Despite extensive literature investigating the effect in adults, little work has been done in young children. In three preregistered studies (N = 38, 35, 172; convenience samples from the Northeastern United States), first, we showed…

On average, deaf and hard-of-hearing (DHH) children have difficulty developing expressive spoken vocabulary comparable to hearing peers. Yet, there are no evidence-based practices to guide classroom instruction for teachers of the deaf. Retrieval practice--a robust learning strategy--has been shown to improve children's retention of vocabulary,…

There is a heated debate on a learning paradigm known as "fast mapping" for its early neocortical dependence and retained memory over time for amnesic patients with hippocampal system damage. Whether the fast mapping allows hippocampus independent learning and induces rapid integration is poorly understood. The present study aims to…

Experiences occur in a continual succession, and the temporal structure of those experiences is often preserved in memory. The temporal contiguity effect of free recall reveals the temporal structure of memory: when a particular item is remembered, the next response is likely to come from a nearby list position. This effect is remarkably robust,…

Background: Retrieval practice promotes retention of learned information more than restudying the information. However, benefits of multiple-choice testing over restudying in real-world educational contexts and the role of practically relevant moderators such as feedback and learners' ability to retrieve tested content from memory (i.e.,…

The retention of fundamental mathematical skills is imperative to provide a foundation on which new skills are developed. Educators often lament about student retention. Cognitive scientists and educators have explored teaching methods that produce learning which endures over time. We wanted to know if using spaced recall quizzes would prevent our…

Numerous studies have shown that learned information practiced by testing is better retained than that practiced by restudying (the testing effect). However, results are inconsistent regarding the effect of working memory (WM) capacity on the testing effect. Here, we hypothesize that the effect of WM only emerges when task demands challenge WM…

Spaced retrieval practice consists of repetitions of the same retrieval event distributed through time. This learning strategy combines two "desirable difficulties": retrieval practice and spacing effects. We carried out meta-analyses on 29 studies investigating the benefit of spacing out retrieval practice episodes on final retention.…

Evidence-based practice in education is the implementation of research-supported teaching tools to enhance students' learning. Retrieval practice is among the top performing learning techniques in scientific literature, with decades of research supporting its incorporation in educational contexts. Testing enhances posterior performance of the…
