Is Retrieval Practice Always Superior to Restudy?

A classic study by Roediger and Karpicke (2006a) investigated the relative benefits of restudy versus retrieval practice, or “test”, on memory retention. Repeated studying was superior to repeated testing when memory was tested immediately (all study > multiple study/single test > single study/multiple tests). Strikingly, the pattern reversed when memory was tested after a days-long delay, with best performance in a single study/multiple tests condition. As each study period was minutes-long and contained repeated reading of a to-be-remembered text passage, we were interested whether the striking benefit for repeated testing at the expense of any restudy replicates when study opportunities are brief, akin to a single mention of a fact in a lecture. Participants encountered academically relevant facts a total of three times, each time either studied (S) or self-tested (T). Final test followed immediately or after a delay (Experiment 1: two days, Experiment 2: seven days). Partially replicating prior work, immediate memory benefited from repeated study (SSS > SST > STT), but the pattern did not reverse after a delay. Instead, memory was superior for facts the were restudied in addition to self-tested (SST > STT = SSS). We further investigated whether restudy after a test (STS) provides additional benefits compared to restudy before test (SST), but found comparably high delayed recall in both conditions. The results show that under some circumstances, balancing repetition and testing can allow for more information to be learned and retained long-term.

Self-protecting motivation, indexed by self-threat, modifies retrieval-induced-forgetting and confidence in employment decision bias against out-group targets

Human memory is malleable by both social and motivational factors and holds information relevant to workplace decisions. Retrieval-induced forgetting (RIF) describes a phenomenon where retrieval practice impairs subsequent memory for related (unpracticed) information. We report two RIF experiments. Chinese participants received a mild self-threat manipulation (Experiment 2) or not (Experiment 1) before an ethnicity-RIF task that involved practicing negative traits of either in-group (Chinese) or an out-group (Japanese) target. After a subsequent memory test, participants selected their preferred applicant for employment. RIF scores correspond to forgetting of unpracticed positive traits of one target (Rp−) relative to the recall of practiced negative traits of the other target (Rp+). Enhanced forgetting of positive traits was found in both experiments for both targets. Across experiments, a significant target by threat interaction showed that target ethnicity modified RIF (an ethnicity-RIF effect). Inducing a self-protecting motivation enhanced RIF effects for the out-group (Japanese) target. In a subsequent employment decision, there was a strong bias to select the in-group target, with the confidence in these decisions being associated with RIF scores. This study suggests that rehearsing negative traits of minority applicants can affect metacognitive aspects of employment decisions, possibly by shaping the schemas available to the majority (in-group) employer. To disrupt systemic racism, recruitment practices should aim to offset a human motivation to protect one-self, when exposed to a relatively mild threat to self-esteem. Discussing the negative traits of minority applicants is a critical, and sensitive, aspect of decision-making that warrants careful practice. These data suggest that recruiting individuals should be reminded of their personal strengths in this context, not their vulnerabilities, to secure their decision-making for fairer recruitment practice.

The Effects of Retrieval Practice Across Levels of Thinking and Retention Interval on Reading Comprehension

The present study examined the effect of different types of retrieval practice on reading comprehension across levels of thinking and retention interval in a classroom setting. One hundred undergraduates divided into two retention interval groups (short- and long-retention interval) were asked to read a passage on a topic in Cognitive Psychology and were then required to engage in a retrieval practice learning strategy using the two types of question format (production test and recognition test) and different levels of thinking (lower-order thinking and higher-order thinking). A three-way mixed ANOVA statistical test was used to analyse the data and found no significant differences in reading comprehension across the different types of retrieval practice, suggesting that the performance when using the recognition test is equivalent to when using the production test. The difference in reading comprehension between the different types of retention interval also was not observed, indicating that students in the short-retention interval group retained just as much information as those in the long-retention interval group. Additionally, the present study observed a significant difference in students’ reading comprehension between different levels of thinking, signifying that the students’ performance for the lower-level thinking questions was better than that for the higher-level thinking questions. The present finding contributed to the existing body of knowledge in which it suggested that the performance in reading comprehension when using a recognition test, particularly a well-constructed one, with competitive alternatives was equivalent to when using a production test.

Interleaving Retrieval Practice Promotes Science Learning

Can interleaved retrieval practice enhance learning in classrooms? Across a four-week period, students (N = 155) took a weekly quiz in their science courses testing half of the concepts taught in that week. Questions on each quiz were either blocked by concept or interleaved with different concepts. A month after the final quiz, students were tested on the concepts covered in the four-week period. Replicating the retrieval practice effect, participants performed better on concepts that had been on blocked quizzes (M = 54%, SD = 28%) than on concepts not been quizzed (M = 47%, SD = 20%, d = .30). Interleaved quizzes led to even greater benefits, revealing an interleaving benefit: participants performed better on concepts that had been on interleaved quizzes (M = 63%, SD = 26%), than concepts that had been on blocked quizzes (d = .35). These results demonstrate a cost-effective strategy to promote classroom learning.

Sleep bolsters schematically incongruent memories

Our ability to recall memories is improved when sleep follows learning, suggesting that sleep facilitates memory consolidation. A number of factors are thought to influence the impact of sleep on newly learned information, such as whether or not we rehearse that information (e.g. via restudy or retrieval practice), or the extent to which the information is consistent with our pre-existing schematic knowledge. In this pre-registered, online study, we examined the effects of both rehearsal and schematic congruency on overnight consolidation. Participants learned noun-colour pairings (e.g. elephant-red) and rated each pairing as plausible or implausible before completing a baseline memory assessment. Afterwards, participants engaged in a period of restudy or retrieval practice for the pairings, and then entered a 12 h retention interval of overnight sleep or daytime wakefulness. Follow-up assessments were completed immediately after sleep or wake, and again 24 h after learning. Our data indicated that overnight consolidation was amplified for restudied relative to retested noun-colour pairings, but only when sleep occurred soon after learning. Furthermore, whereas plausible (i.e. schematically congruent) pairings were generally better remembered than implausible (i.e. schematically incongruent) pairings, sleep (vs wake) reduced the retention advantage for plausible (vs implausible) information. This finding challenges the notion that schema-conformant memories are preferentially strengthened during post-learning sleep.

Retrieval practice transfer effects for multielement event triplets

Retrieval practice (RP) leads to improved retention relative to re-exposure and is considered a robust phenomenon when the final test conditions are identical to RP conditions. However, the extent to which RP ‘transfers' to related material is less clear. Here, we tested for RP transfer effects under conditions known to induce integration of associated material at encoding, which may make transfer more likely. Participants learned multielement triplets (locations, animals and objects) and one pairwise association from each triplet was tested through RP, re-exposed, or not re-exposed (control). Two days later participants completed a final test of all pairwise associations. We found no evidence for an RP effect compared to re-exposure, but both tested/re-exposed pairs were better remembered than the not re-exposed control condition. We also found that transfer occurred from both tested to untested and re-exposed to not re-exposed pairs. Our results highlight that RP and re-exposure can boost retention for directly tested/re-exposed event pairs and associated but untested/not re-exposed event pairs, suggesting re-exposure of integrated information can be of pedagogical value. The results also question the boundary conditions for an increase in retention for RP relative to re-exposure, highlighting the need for a better theoretical understanding of RP effects.

Key Theoretical Principles to Implement the Student-Centered Learning and Teaching Process

The starting point of this article is the United Nations Agenda 2030, an outstanding international project, with a special emphasis on Goal 4 that focuses on providing «Quality Education», an objective that the current global pandemic is making more and more challenging. All the educational agencies, putting academia first, should pursue the aims of Goal 4, setting up a well-established plan with clearly stated objectives. Starting from the controversial principle that «learning is impeded by teaching», some relevant pedagogical practices are examined, such as Retrieval Practice, CLIL, and Microlanguages. Nevertheless, the core of this article deals with some pairs and triples of key theoretical principles, besides some basic theoretical areas, any educator should be familiar with and apply during her/his approach to the learning/teaching process.
