Timing of feedback and retrieval practice: a laboratory study with EFL students

The aim of this empirical laboratory study was to investigate the effect of immediate and delayed feedback on retrieval practice among Saudi EFL learners using short-answer tests administered at three different time points: immediately, one week later, and one month later. A total of 177 Saudi undergraduate EFL students were randomly assigned to four groups: Repeated Studying, Repeated Testing-no feedback, Repeated Testing-immediate feedback, and Repeated Testing-delayed feedback. Additionally, a restudy control group was included to compare retrieval practice and feedback effects to the restudy condition. Participants read a 487-word prose passage and underwent testing at the specified intervals. Results revealed that retrieval practice without feedback outperformed repeated studying in the one-month delayed test. Both immediate and delayed feedback groups outperform the no-feedback and restudying groups. Moreover, immediate feedback was found to be more effective than delayed feedback in enhancing long-term retention. These findings emphasize the importance of providing timely feedback to optimize retrieval practice and improve learning outcomes in EFL contexts.

Redundancy effect of initial enactment encoding and subsequent testing on memory enhancement: Insights from an electrophysiological study

Testing is more beneficial for memory retention than restudying the same content. However, the effect of the initial encoding method on the testing effect remains unclear. In this study, a classical testing effect paradigm was employed, along with event-related potentials (ERP), to investigate the electrophysiological processes underlying the effect of enactment encoding on the testing effect. Participants were randomly assigned to the Self-Performed Test (SPT) or Verbalized Test (VT) groups. Both groups underwent three stages: an initial encoding phase, an initial test phase (comprising a source memory task and a restudy task), and a final test phase. During the initial encoding phase, the SPT group encoded action phrases through enactment, while the VT group encoded information through reading. During the initial test phase, the SPT group exhibited superior recognition performance in item memory compared with the VT group. Both groups exhibited significant parietal old/new effects in the source memory task, with only the SPT group displaying parietal positivity during the restudy task. During the final test phase, the behavioral testing effect was exclusively observed in the VT group. Furthermore, the VT group displayed a more pronounced parietal positivity in the test condition compared to the restudy condition, while the parietal positivity between the two conditions was comparable in the SPT group. In summary, the absence of a final behavioral testing effect in the SPT group may be attributed to both enactment and testing primarily enhancing memory performance through recollection-based retrieval, as indicated by the parietal positivity. Consequently, the initial enactment encoding method leaves limited scope for further improvements through subsequent testing. These findings suggest that initial enactment encoding, and subsequent testing may be redundant in improving episodic memory performance.

Does testing potentiate new learning because it enables learners to use better strategies?

Testing can potentiate new learning, which is often called the forward testing effect. One potential explanation for this benefit is that testing might enable participants to use more effective learning strategies subsequently. We investigated this possibility by asking participants to report their encoding strategies in a multi-list foreign language learning paradigm with four preregistered experiments and one non-preregistered pilot experiment. In Experiments 1-3, participants learned three lists of Chinese-English pairs; one group took a test after every list (i.e., test condition) and the other group took a test only for the criterial List 3 (i.e., restudy condition). In addition, participants completed a transfer test and a study strategy survey. Although we found a forward testing effect in all experiments, participants in the test and restudy conditions did not report differences in strategies. In Experiments 4 and 5, we used a within-subject design so that we could correlate changes in strategy use with the magnitude of the forward testing effect on an individual level. Interestingly, individual differences in strategy change were moderately associated with the magnitude of the forward testing effect, but even here, strategy change did not mediate the effect of testing on performance. Overall, our data showed that, at least for foreign language learning of Chinese characters, interim testing did not enhance new learning by altering participants' subsequent encoding strategies. Moreover, our data showed that interim testing did not promote the transfer of Chinese language learning to novel characters. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Buildup and release from proactive interference: The forward testing effect in children’s spatial memory

Previous work has indicated that testing can enhance memory for subsequently studied new information by reducing proactive interference from previously studied information. Here, we examined this forward testing effect in children’s spatial memory. Kindergartners (5–6 years) and younger (7–8 years) and older (9–10 years) elementary school children studied four successively presented 3 × 3 arrays, each composed of the same 9 objects. The children were asked to memorize the locations of the objects that differed across the four arrays. Following presentation of each of the first three arrays, memory for the object locations of the respective array was tested (testing condition) or the array was re-presented for additional study (restudy condition). Results revealed that testing Arrays 1 to 3 enhanced children’s object location memory for Array 4 relative to restudying. Moreover, children in the testing condition were less likely to confuse Array 4 locations with previous locations, suggesting that testing reduces the buildup of proactive interference. Both effects were found regardless of age. Thus, the current findings indicate that testing is an effective means to resolve proactive interference and, in this way, to enhance children’s learning and remembering of spatial information even before the time of school entry.

Lower constraint testing enhances the testing effect for some contextual details but not others.

Retrieval practice has been shown to be an effective means of learning new information, a memory phenomenon known as the testing effect or the retrieval practice effect. Some work suggests that the magnitude of the testing effect can be enhanced when the test used for retrieval practice uses fewer cues to retrieve previously studied information. It is unclear, however, whether such testing benefits extend to peripheral contextual details associated with studied materials (e.g., location where stimuli appear, font color in which items are presented, etc.). In this experiment, we examine both item memory (i.e., memory for the studied items) and context memory under conditions where the intervening test offers fewer cues (i.e., lower constraint) compared to more cues (higher constraint) to better understand item and context memory testing effects. Participants first studied word pairs presented in one of eight locations as well as in either red or green font color. Then, in the re-exposure phase, participants processed materials in two types of intervening tests (lower constraint and a higher constraint test) as well as in a restudy condition, before a final memory test. For item memory, results showed that memory was better in the lower constraint testing condition compared to both the higher constraint testing condition as well as the restudy (control) condition. For context memory, results indicated improved memory for location context under lower constraint testing compared to both higher constraint testing and restudy conditions. There was no difference in memory, however, for color context across all conditions. Overall, these findings suggest that providing fewer cues to aid retrieval in the intervening test can induce better memory for both items as well as some contextual details.

The influence of repeated study and repeated testing on the testing effect and the transfer effect over time.

Many studies have shown that compared to the restudy condition (RS), retrieval practice (RP) enhances the long-retention memory of retrieved items (i.e., the testing effect), and facilitates later memory of non-retrieved but related items (i.e., the transfer effect). However, previous studies have usually used repeated study and repeated testing, which are included in study-testing cycles. Therefore, it is unclear to what extent the factors of repeated study and repeated testing influence testing and transfer effects over time. In this study, participants studied sentences that described various episodes, then tested a half subset of the original sentences under three conditions (RP, RS, control). After retention intervals of 10 min, 1 day and 7 days, they recalled all of the information in the sentences. The results showed that the testing effect was enhanced by repeated study or repeated testing, while the transfer effect occurred only after both repeated study and repeated testing. Furthermore, repeated study or repeated testing slowed down the forgetting of retrieved items, while the forgetting of non-retrieved items occurred after both repeated study and repeated testing. The testing effect increased over time, but the transfer effect remained relatively stable over time. These results clarified different roles of multiple study repetitions and testing opportunities in the testing effect and the transfer effect, and suggest that the repeated retrieval could be combined with repeated study to optimally promote long-term retention of the memory of tested and non-tested items.

The Forward Testing Effect Is Resistant to Acute Psychosocial Retrieval Stress.

The forward testing effect refers to the finding that testing of previously studied information improves memory for subsequently studied newer information. Recent research showed that the effect is immune to acute psychosocial encoding/retrieval stress, i.e., stress that is induced before initial encoding. The present study investigated whether the forward testing effect is also robust to acute psychosocial retrieval stress, i.e., stress that is induced after encoding but before retrieval of the critical item list. Participants (N = 128) studied three lists of words in anticipation of a final cumulative recall test. Participants were tested immediately on Lists 1 and 2 (testing condition) or restudied the two lists after initial study (restudy condition). After study of the critical List 3, psychosocial stress was induced in half of the participants (stress group), whereas no stress was induced in the other half (control group). The Trier Social Stress Test for Groups (TSST-G) was used for stress induction. Salivary cortisol, alpha amylase, and subjective stress were repeatedly measured. The results of the criterion test showed a generally detrimental effect of psychosocial retrieval stress on List 3 recall. Importantly, the forward testing effect was unaffected by retrieval stress. The findings are discussed with respect to current theories of the forward testing effect.

The benefits of successive relearning on multiple learning outcomes.

Successive relearning involves repeated retrieval practice of the same information (with feedback) over multiple, spaced sessions. We implemented successive relearning in an introductory psychology class to explore potential learning benefits. After each weekly lecture, students were sent links via email to engage in three learning practice sessions, each separated by two days. Half the students engaged in successive relearning (relearn condition), answering 20 fill-in-the-blank questions with corrective feedback. Within each session, correctly answered questions were dropped, whereas incorrectly answered questions were presented up to 2 more times. The other half of students restudied the same 20 sentences without blanks twice per session (restudy condition). Unlike previous research, we controlled the exposure duration of the learning materials between the relearn and restudy conditions. Learning practice sessions continued throughout the remaining 10 weeks of the semester, with students alternating each week between the relearning and restudying tasks. Recall of course material at the end of the semester was better for relearning compared to restudying. Increased recall during relearning sessions was associated with further learning benefits including improved metacognition, increased self-reported sense of mastery, increased attentional control, and reduced anxiety. Individual differences were not associated with the benefit of relearning over restudying in the retention tests. Qualitative feedback indicated that students found successive relearning to be enjoyable and valuable. Our research indicates that successive relearning is a valuable addition to any university course and is easy to implement using digital resources.

Progressive retrieval practice leads to greater memory for image-word pairs than standard retrieval practice

ABSTRACT The benefits of retrieval practice on learning are robust and have transferred from laboratory findings to many real-world educational settings. We report two experiments that investigated a novel retrieval practice technique for remembering arbitrary associations (image-word pairs), with and without reward as a motivator. As well as typical retrieval practice and restudy conditions, we added a third condition of graded retrieval practice in which the image cue was partially released in a progressive process. Experiment 1 found significant benefits of retrieval practice over restudy, with an additional benefit of graded retrieval practice compared with standard retrieval practice after a 48-hour delay between study and retrieval. Experiment 2 included a reward manipulation by giving participants money based on their memory performance. The findings replicated the retrieval practice effects observed in Experiment 1, including a robust advantage for graded retrieval practice. Reward neither changed the additive advantage of graded recall nor the benefit of retrieval practice. The present study adds to the literature indicating that retrieval with progressive retrieval cues can boost the benefit of retrieval practice by generating repeated retrieval attempts. This benefit occurs most for items that are neither too easy nor too challenging to retrieve.

The testing effect with free recall: Organization, attention, and order effects

Memory retrieval not only reveals but can also change memory, as shown by direct and indirect (e.g., forward) testing effects. Three experiments examined the testing effect with free recall, with respect to attention, organization and forward testing effects. In Experiment 1, participants learned two categorized word lists, one followed by retrieval practice and the other by restudy; memory for both lists was assessed on a final free recall test two days later. Retrieval practice and restudy were conducted under full attention (FA) or divided attention (DA). Final recall was significantly diminished by DA in the restudy but not retrieval condition, indicating that the encoding consequences of retrieval are relatively resistant to distraction. However, a negative testing effect was found on final recall (in the FA condition). Experiments 2 and 3 implemented a between-subjects version of the experiment (FA condition only) in which both learning blocks were in the retrieval or restudy condition. Final recall now exhibited a positive testing effect. Analyses of the order of learning blocks revealed strong forward-testing effects in which the study list following the retrieval block produced superior final recall, a benefit accruing to the restudy condition in the within-subject design (Experiment 1) and to the retrieval condition in the between-subjects design (Experiments 2 and 3). In contrast, no direct testing effects were found on the first list, a result analyzed in terms of prior research that often conflated forward and direct testing effects. Finally, retrieval practice generally did not impact organization (as measured by category clustering on the final recall test), indicating that the organization effect found in earlier research may not be readily replicated.

Retrieval Practice Enhances New Learning but does Not Affect Performance in Subsequent Arithmetic Tasks.

The forward testing effect is an indirect benefit of retrieval practice. It refers to the finding that retrieval practice of previously studied information enhances learning and retention of subsequently studied other information in episodic memory tasks. Here, two experiments were conducted that investigated whether retrieval practice influences participants’ performance in other tasks, i.e., arithmetic tasks. Participants studied three lists of words in anticipation of a final recall test. In the testing condition, participants were immediately tested on lists 1 and 2 after study of each list, whereas in the restudy condition, they restudied lists 1 and 2 after initial study. Before and after study of list 3, participants did an arithmetic task. Finally, participants were tested on list 3, list 2, and list 1. Different arithmetic tasks were used in the two experiments. Participants did a modular arithmetic task in Experiment 1a and a single-digit multiplication task in Experiment 1b. The results of both experiments showed a forward testing effect with interim testing of lists 1 and 2 enhancing list 3 recall in the list 3 recall test, but no effects of recall testing of lists 1 and 2 for participants’ performance in the arithmetic tasks. The findings are discussed with respect to cognitive load theory and current theories of the forward testing effect.

Retrieval-induced forgetting with novel visual stimuli is retrieval-specific and strength- independent

ABSTRACT Retrieval-induced forgetting (RIF) is the phenomenon whereby remembering a subset of learned items can reduce memory for other related items. There are two main explanations for this effect: the competition account and the inhibition account. Most research to date has favoured the inhibition account, though two potential confounds have been identified in the evidence for key predictions of the account: (1) Using binary measures of accuracy may make it difficult to detect correlations between the magnitude of RIF and the increase in recall for practised items that is predicted by the competition account (strength dependence), and (2) typical non-competitive restudy may be too weak a form of practice to elicit detectible RIF effects. The present study aimed to test these contentions by adapting the RIF paradigm to allow a more graded measurement of memory strength and a more active form of non-competitive practice. We trained participants (N = 87) to draw sets of novel shapes from memory, using colour as a category cue and overlaid patterns as individual item recall cues. Responses were graded based on the number of features present and items underwent retrieval practice, copying practice (as a more effective form of restudy), or no practice. The results demonstrated RIF in the retrieval practice condition, but no evidence of RIF in the restudy condition, despite a large memory gain for practised items, supporting the notion of retrieval specificity. There was no evidence of strength dependence in any condition. Our results are consistent with the forgetting in this experiment being driven by inhibition.

Effects of retrieval and emotion on within-item associative memory – Evidence from ERP and oscillatory subsequent memory effects

Previous studies have shown the effects of retrieval practice and emotion on associative memory separately. However, it is yet not clear what are the related neural mechanisms and how the two factors together influence associative memory? We examined this question by instructing participants to memorize emotional or neutral words using different ways of learning. Behaviorally, the source memory was enhanced by the retrieval practice compared to the restudy condition, and impaired by the negative compared to the neutral condition without an interaction. Consistent neural effects of retrieval practice were also found, in which subsequent memory effects (SME) of 500–700 ms parietal ERPs and alpha desynchronization were found for the retrieval practice but not for the restudy. No significant difference of SME for ERPs and time-frequency analyses regarding the emotion effect was found. These results demonstrated the neural mechanism for the effects of emotion and retrieval practice on subsequent memory.

Less Constrained Practice Tests Enhance the Testing Effect for Item Memory but Not Context Memory

Abstract Research shows that retrieval practice, compared with restudying, improves memory for previously learned information (i.e., testing effect); however, less work has examined testing effects for context memory (i.e., memory for associated details encountered at study). The present investigation examines the extent to which giving less information (i.e., fewer constraints) on a practice test improves item and context (source and font color) memory on a final test. Participants studied highly associated word pairs in red or green font. Participants were then shown the word pairs in a lower-constraint practice test (e.g., “brief-____”), higher-constraint practice test (e.g., “open-coels”), or restudy condition (e.g., “blaze-fire”). Results showed better item memory in the lower-constraint test than in both the higher-constraint test and restudy, but there was no difference for context memory across conditions. These findings demonstrate that using a less constrained practice test can increase the effectiveness of this learning strategy, but benefits may not transfer to contextual details.

A mind-wandering account of the testing effect: Does context variation matter?

The learning benefits of retrieval practice have been linked to reduced mind-wandering, but the reasons why testing offers such an attentional advantage have scarcely been explored. Here, we investigate the extent that the inherent change in learning context during retrieval practice (i.e., interleaved study and retrieval) attenuates mind-wandering, relative to restudy (i.e., massed study). Learners (N = 120) either restudied video lectures (SSSS) or engaged in a combination of study and retrieval (SRSR). Further, they used either the same study mode - the video lecture (S) or its corresponding transcript (S') only (i.e., SSSS or S'S'S'S'; SRSR or S'RS'R), or different study modes - alternated between the video and its transcript (i.e., SS'SS' or S'SS'S; SRS'R or S'RSR). Learners' mind-wandering tendencies were captured using a direct-probing approach, and a free-recall test was administered 1 week later. Retrieval practice produced less mind-wandering than restudy, and this attentional difference mediated the recall advantage of retrieval practice. Of note, in the restudy condition, alternating between study modes inoculated against mind-wandering relative to using the same mode, but only for as long as the study mode remained "new" to learners - when they returned to a previously encountered "old" study mode, mind-wandering surged. In contrast, retrieval practice consistently sustained learners' attention over time, whether or not their study modes were the same or different. Theoretical implications for an attentional account of retrieval-based learning are discussed.

Testing and transfer: Retrieval practice effects across test formats in English vocabulary learning in school

AbstractThe application of knowledge to new contexts (i.e., transfer) is a central aim of learning processes and has become a new focus of testing effect research. In a quasi‐experimental design, we investigated the transfer of retrieval practice effects on English vocabulary learning on eighth‐grade students (N = 182) by applying a typical testing effect study paradigm including study, initial test or restudy, and final test. The final test comprised four test formats, one identical to the initial test (non‐transfer context), and three deviating from the initial test (transfer context). Comparing testing and restudy conditions yielded a significant multivariate effect of testing across all final test formats and significant univariate effects in three of the four test formats. Comparing transfer and non‐transfer contexts revealed smaller retrieval practice effects when transfer was required. The results are discussed against the theoretical background of transfer‐appropriate‐processing, elaborative retrieval, and a distribution‐based model of retrieval.

Retrieval practice enhances memory for names in survivors of stroke.

Objective: Accumulating evidence suggests that retrieval practice (testing during learning) enhances memory in clinical populations. However, no study to date has examined the efficacy of retrieval practice in stroke survivors, despite the negative impact of poststroke memory difficulties. We investigated whether retrieval practice enhances memory for names in stroke survivors and healthy controls. Method: Using a within- and between-subjects design, 20 stroke survivors and 20 healthy controls completed an experimental paradigm that required them to learn 18 name-face pairs divided across 3 learning conditions (spaced restudy, retrieval practice, massed study). A mixed analysis of variance compared participants' name recall across conditions after 30 min and 7 days. Results: There was a main effect of learning condition (p < .001, ηp² = .67) and a significant Time × Condition interaction (p < .001, ηp² = .25). Post hoc comparisons revealed that retrieval practice was the superior learning condition in both groups after 30 min. After 7 days, there was no significant difference between the retrieval practice and spaced restudy conditions in stroke survivors (p = .08, d = 0.41), although retrieval practice remained superior to massed study (p = .001, d = 0.88). Conclusions: Retrieval practice is a promising memory technique that significantly enhanced stroke survivors' memory for names. Given similar performance in the retrieval practice and spaced restudy conditions after 7 days, stroke survivors may benefit from multiple presentations of information during learning, rather than 1 prolonged exposure. Future studies should investigate whether additional retrieval opportunities might prolong the beneficial effect of testing during learning.

Retrieval practice facilitation of family psychoeducation in people with early psychosis

BackgroundProviding early psychosis (EP) individuals with family psychoeducation (FPE) can reduce symptoms and improve clinical outcomes. However, relational memory problems may limit prospective utilization of FPE information. This study examines whether memory for FPE can be improved by testing participants during the initial FPE workshop presentation. MethodData were obtained from 20 people with EP and 20 demographically matched healthy comparison subjects (HC). During session one, FPE was presented in small group workshops, with half of the information re-studied twice (re-study condition) and the remaining information tested twice using cued recall tasks (retrieval practice condition). One week later (session two), delayed cued recall was tested for all FPE information. “Testing effects” (i.e., better memory following retrieval practice versus re-study) were examined across all items (standard analysis) and also limited to items successfully retrieved during session one (conditionalized analysis). ResultsHC had better initial recall and learned more over the two retrieval practice trials than EP. However, HC also lost more information than EP over the one-week delay. Both groups produced a significant testing effect. This effect was smaller in EP versus HC across all test items, but did not differ for the conditionalized analysis. Negative symptoms were inversely correlated with delayed cued recall in EP. ConclusionsEP participants benefit from retrieval practice, with participants with less severe negative symptoms showing the greatest benefit. These results encourage use of memory tests during group psychoeducation to improve subsequent long-term recall of clinically relevant information.

True-False Testing on Trial: Guilty as Charged or Falsely Accused?

Although widely used, the true-false test is often regarded as a superficial or even harmful test, one that lacks the pedagogical efficacy of more substantive tests (e.g., cued-recall or short-answer tests). Such charges, however, lack conclusive evidence and may, in some cases, be false. Across four experiments, we investigated how true-false testing of studied passages (e.g., on Yellowstone National Park) might enhance—or be optimized to enhance—performance on subsequent cued-recall tests. In Experiments 1–2, relative to control performance that did not benefit from any additional exposure, we found that (a) the evaluation of true statements enhanced the recall of tested (but not related) content and that (b) the evaluation of false statements enhanced the recall of related (but not tested) content, a differential pattern of benefits that did not depend on the syntactic structure of the test items. Moreover, when competitive clauses were embedded within the true-false items of Experiment 3 (e.g., True or false? Castle Geyser (not Steamboat Geyser) is the tallest geyser), we found that the evaluation of both types of statements enhanced the recall of both types of content. Finally, in Experiment 4, these holistic benefits proved robust to a retention interval of 48 h and were comparable with the benefits of a restudy condition in which learners restudied all of the propositions that could have been retrieved in the evaluation of the true-false items. Accordingly, although it was not uncommon for participants to misremember information as a consequence of true-false practice, our findings broadly indicate that, especially when carefully constructed, true-false tests can elicit beneficial, not superficial, processes that belie their poor reputation.

Creating drawings enhances learning by teaching.

This study tested whether creating drawings helps students generate higher-quality oral explanations during learning by teaching, thereby enhancing learning outcomes. 120 college students studied a scientific text about the human respiratory system. Students then either taught the material on video to a fictitious peer by orally explaining (explain-only), creating drawings (draw-only), or creating drawings while orally explaining (explain-and-draw). A control group of students spent the same amount of time restudying the lesson (restudy). One week later all students completed a posttest consisting of retention, transfer, and drawing questions. All three teaching conditions significantly outperformed the restudy condition on the posttest (d′s ranging from .80 to 1.46). Critically, the explain-and-draw group also significantly outperformed the explain-only (d = .99) and the draw-only (d = .65) groups. Consistent with our primary hypotheses, the explain-and-draw group produced more elaborative oral explanations than the explain-only group, which partially explained the benefits of drawing while explaining on learning outcomes. Overall, this study demonstrates that drawing facilitates explaining and enhances the effectiveness of learning by teaching. (PsycInfo Database Record (c) 2020 APA, all rights reserved)
