Using elaborative interrogation to facilitate acquisition of factual information in cooperative learning settings: One good strategy deserves another

The primary purpose of this study was to determine whether providing 6th-grade students with cooperative elaborative interrogation instruction would facilitate learning relative to providing them with cooperative learning, elaborative interrogation or reading-for-under-standing instructions. All students were presented with 36 factual statements about six animals. Cooperative elaborative interrogation students were instructed to work collaboratively and use their prior knowledge to state why each fact is true. Cooperative learning students were told to work collaboratively to learn target materials, while elaborative interrogation students were instructed to generate answers to the why questions on their own. Reading-control students were also on their own and instructed to read the animal facts for understanding. For immediate free recall and immediate associative matching tests, students in the experimental conditions outperformed those in the control condition. Cooperative elaborative interrogation and elaborative interrogation students maintained this advantage on a 30-day follow-up associative matching test, with elaborative interrogation students maintaining a significant advantage relative to reading controls on a 60-day associative matching follow-up. (There was also a strong trend favouring the cooperative elaborative interrogation condition on this 60-day measure.) The quality of the ‘why’ answer affected learning: Generating and listening to scientifically correct answers that used relevant prior knowledge to clarify target information was associated with better memory for facts than were other types of study responses. Students in this study learned the most when they were explicitly directed to activate relevant prior knowledge that supports and clarifies new information–processing that occurs following either small-group or individual elaborative interrogation instruction.     

Enhancing learning through strategy instruction and group interaction: is active generation of elaborations critical?

We examined strategic intervention when learners were actively engaged in group discussion to assess the impact of peer interaction. In addition, memory performance was compared between students who generated or evaluated elaborations when using the elaborative interrogation strategy, as well as between a supported strategy where learners were provided with explanatory elaborations and a self‐study condition. Introductory psychology students (N=263) in groups of 3 to 5 members studied sixty facts about familiar and unfamiliar animals. Overall, the potency of elaborative interrogation was confirmed regardless of whether students studied interactively or independently. The contribution of group members in facilitating knowledge when the group was able to share sophisticated strategic information also was highlighted. Most critically, when background knowledge was sufficient to promote connections between existing and new material, it was the active generation of elaborations that maximized learning.

The self-choice elaboration effects on incidental memory of Japanese historical facts

The subjects performed an orienting task involving 3 conditions, followed by unexpected tests which included free recall, name-matching and name-selec tion. Conditions were designed to force self-generated elaboration, self-choice elaboration, and experimenter-provided elaboration. In the self-generated elaboration condition, subjects were presented target sentences, e.g., Nobunaga ODA burned down ENRYAKUJI Temple, and asked to answer an elaborative interrogation, e.g., Why did Nobunaga ODA burn down ENRYAKUJI Temple? about each sentence. In the self-choice elaboration condition, subjects selected one of the alternative answers to an elaborative interrogation about each sentence. In the experimenter provided elaboration condition, subjects were presented an answer which they rated for congruity as the correct answer to the elaborative interrogation. In the free recall test, self generated elaboration led to better performance than the other two conditions for which no difference was observed. However, in the name-matching and name-selection tests, scores were better for self choice elaboration and self-generated elaboration than for experimenter-provided elaboration. These results were interpreted as demonstrating that self choice elaboration, in addition to self-generated elaboration, led to effective encoding in memory.     

RESEARCH INTO PRACTICE

The effectiveness of two variations of elaborative interrogation for group settings was investigated in an experiment where college students learned factual sentence information. The interrogation strategy variations were compared to a challenging, ecologically valid control condition in which students were instructed to use whatever strategies they thought would work best for the sentence‐learning task. Results indicated that the written and the oral variations of elaborative interrogation were equally effective and that both variations significantly enhanced the students' performance on an associative matching task but not on a recall task.     

Considering prior knowledge when using elaborative interrogation

Previous studies have promoted the use of elaborative interrogation (a “why”-questioning strategy) for the acquisition of factual information. One assumption in these studies is that prior knowledge influences when students will be able to use the strategy, with greater prior knowledge leading to higher recall performance. In the studies reviewed here, the effect of prior knowledge on strategy effectiveness was investigated. Specifically, students' performances were compared for materials about which they possessed substantial prior knowledge, little prior knowledge, inconsistent prior knowledge, or shared prior knowledge. In general, the data support the use of elaborative interrogation when studying alone or in dyads especially when learners possess some relevant prior knowledge about the new information.     

Sex differences in elaborative strategies: a developmental analysis.

The present study examined sex differences in the use of elaboration in paired associate learning in adolescence and young adulthood. In Experiment 1, 48 eighth grade and 48 tenth grade students were asked to recall 24 word pairs, half of which were high frequency pairs, and half low frequency pairs. After recall, students reported the type of strategy used for each word pair (reading the pairs carefully, rehearsing the words, using imagery or constructing a verbal connection). Females used elaborative strategies more often, were more likely to recall elaborated pairs, and recalled more word pairs than males at both ages. These effects were observed in both high and low frequency word pairs. There was also a main effect of frequency, with elaboration more common with high frequency word pairs. In Experiment 2, college students performed the same paired-associates learning task, but with the added instruction to describe their elaborations in a sentence. At this age, there was a sex by materials interaction, with sex differences in strategy use only present with low frequency word pairs. These findings indicate that sex differences diminish under more favorable task conditions that encourage strategy use (high frequency word pairs) as males and females become more proficient strategy users, but remain under less favorable circumstances. An examination of the types of elaborations generated by college students indicated although males and females produced similar types of elaborations to the word pairs, sex differences in the recallability of low frequency words appeared with less interactive and more idiosyncratic elaborations.     

Helping students acquire belief-inconsistent and belief-consistent science facts: Comparisons between individual and dyad study using elaborative interrogatin,self-selected study and repetitious-reading

One hundred and eighty four grade 6 and 7 students processed 32 factual statements in one of two studies reported here. Half the statements were consistent with the students' prior knowledge, whereas the remaining facts were inconsistent with it. Students studied the facts alone, or with a partner, by: (1) answering 'why' questions; (2) reading the information for understanding; or (3) selecting their own method of study. Recall (free and cued) and recognition measures (immediate, 30-day, and 60-day) were used to assess learning (immediate, 30-day, and 60-day). Instructions to use elaborative interrogation produced superior learning gains relative to instructing students to read information for understanding or to select their own study strategy. Overall, there were no performance differneces as a function of individual versus dyad study. The quality of the elaborative interrogation study response affected learning. When students generated or listened to a partner's response that clarified the target facts, learning of that information was superior to when students generated or listened to other types of study responses.     

Adult Age Differences in Divided Attention: Effects of Elaboration During Memory Encoding

The present study used attention operating characteristics (AOCs) to examine whether age differences existed in divided attention (DA) performance when both primary (cued recall) and secondary tasks (letter recall) were analyzed simultaneously. Additionally, to determine if age differences in DA might depend on the amount of elaborative processing required at study, participants either read (low elaboration) or generated (high elaboration) target words. AOC analyses indicated that performance was disrupted most when attention was divided at encoding versus retrieval, and dividing attention had a greater negative impact on older adults’ performance relative to younger adults’. Furthermore, the high elaboration condition was less affected by DA than the low elaboration condition for both age groups. The results indicate that although the ability to divide attention declines with age, some elaborative study strategies may be more resistant to DA effects for both younger and older adults.     

The relation between item identification difficulty and elaborative conceptual processing for children and adults

The four experiments concerned the relation between the difficulty of item identification processes, elaborative conceptual processing, and developmental differences in cued recall. Elaborative conceptual processing was manipulated by asking related ("How many are related?"), category ("How many are vehicles?"), and analytic ("How many usually carry freight?") orienting questions about four-word stimuli in which the words were categorically related (Bus-Airplane-Car-Train). The measures of elaborative processing were the speed and accuracy of question answers. Cued recall for the targets (Train) was assessed for one-word (Bus) or two-word (Bus-Airplane) cues, which were varied to determine if elaborative processing affected cue discriminability or constructability, or both. The difficulty of item identification was varied in several ways. In Experiment 1, the graphemic information was degraded in the acquisition stimuli, or the retrieval cues, or the stimulus words were intact. In Experiments 2 and 3, acquisition presentation time was varied and the stimuli were read by the experimenter or the subject. Experiment 4 featured pictures to determine generalizability. The results showed that elaborative conceptual processing facilitates recall. Most important, item identification processes limit elaborative conceptual processing for both words and pictures, and more for children than for college students.     

Elaborative interrogation applied to small and large group contexts

The present study examined the application of elaborative interrogation (EI), a questioning strategy, to ecologically valid classroom contexts. Instruction was provided to individuals, small groups of five, and large groups of 20. Recall performance did not differ as a function of group size. For individuals, small and large groups, EI subjects outperformed repetition control subjects.     

Picture versus question elaboration on young children's learning of sentences containing high- and low-probability content

The main purpose of the two experiments reported here was to compare the potency of two types of elaboration on children's learning of sentence content: The effects of partial picture adjuncts were compared to the effects produced by answering "why"-questions about the relationships specified in the sentences. Five- to seven-year-old children heard sentences of the form, subject/verb/direct object/preposition/instrument. Sentences contained either a high-probability or a low-probability instrument given the semantic context. In Experiment 1, sentences either were accompanied by a partial picture depicting the sentence action but omitting the instrument or were presented without a partial picture accompaniment. Recall was improved by provision of partial pictures at study. In Experiment 2, the sentences were accompanied by complete pictures depicting the sentence content. In both experiments, questioning significantly reduced recall of high-probability sentences, with recall of instruments affected especially negatively. Evidence is presented that insufficient attention to instruments may have been one mechanism mediating depressed recall of high- compared to low-probability instruments in the questioned conditions. In summary, partial pictures improved cued recall of sentences in this study; in contrast, all significant effects produced by answering why-questions were negative ones (i.e., later recall was reduced following interrogation at study).     

The effect of verbal elaborations on memory in young and older adults

The Stein paradigm was used to examine the circumstances under which verbal elaborations enhance memory in young and older adults. Subjects studied target adjectives that were embedded in one of three sentence contexts that varied in elaboration of the subject-adjective relationship: (1) nonelaborated base sentences; (2) base sentences with semantically consistent, but arbitrary verbal, elaborations; and (3) base sentences with explanatory verbal elaborations that clarified the significance of the subject-adjective relationship. The presence of the elaborations was varied at encoding and retrieval, and cued recall of the target adjectives was tested with incidental and intentional learning procedures. In Experiments 1A and 1B, explanatory elaborations at encoding and retrieval yielded the largest memorial facilitation for both young and older adults, and the benefit was comparable for the incidental and intentional learning measures. In Experiment 2, age-related differences in recall were minimal with explanatory elaborations at encoding and retrieval, but larger age differences occurred in the nonelaborated comparison conditions. In Experiment 3, explanatory elaborations present at encoding but not at retrieval enhanced recall when the original Stein stimuli were used, but not with the present stimuli. The implications of these results with regard to the mnemonic efficacy of verbal elaborations for young and older adults are discussed.     

Developmental changes in self-corrected elaboration effects on incidental memory

Abstract:  Two experiments were carried out to investigate the changes across age groups in the effects of self-corrected elaboration on incidental memory. Each participant performed an orienting task involving three conditions: self-corrected, self-generated and experimenter-provided elaboration. The orienting task was followed by free recall tests. In Experiment 1, the participants were sixth-grade and second-grade students. For sixth-grade students the self-corrected elaboration led to a better free recall than the other two elaborations, whereas for the second-grade students, no difference was observed between any of the three elaborations. In Experiment 2, using a longer word list than that in Experiment 1, the participants were undergraduates. The self-corrected and self-generated elaborations led to a better free recall than the experimenter-provided elaboration, and no difference between the former two elaborations was observed. The results obtained from these two experiments were interpreted as showing that the effectiveness of a self-corrected elaboration depends on the participants' age.     

Effects of types of elaboration on children's memories of a story: interaction with academic performance

Two experiments compared the effectiveness of three types of elaboration on incidental and intentional memory for a story: self-generated, self-choice, and experimenter-provided elaboration. In Exp. 1, using the incidental memory paradigm, second graders listened to a fantastic story and then, in the self-generated condition, answered a "why" question about a particular topic in the story. In the self-choice condition, they chose one of the alternative answers to the question and in the experimenter-provided condition, judged the appropriateness of each of two provided answers. This was followed by free-recall and cued-recall tests. Subjects were categorized into two groups, good and poor academic achievers in terms of academic scores in four subject matter areas. For good academic achievers, self-choice elaboration led to a better cued recall than the other two elaboration types. The cued-recall performance of poor achievers was not different with the three conditions. In Exp. 2, using the intentional memory paradigm, the subjects intended to learn a different story and then performed the same procedure as Exp. 1. For poor achievers, self-choice elaboration led to a worse free recall than the other elaboration types, but the free recall of good achievers was not significantly different for the three types of elaboration. The results were interpreted as showing that the effects of self-choice elaboration on incidental and intentional memory were correlated with subjects' academic performance.     

线索强度:检验提取练习效应内部机制的重要变量

研究采用提取练习效应研究的经典范式,通过比较学习材料的线索强度对不同学习策略效果的影响来探讨提取练习效应的内部机制。结果发现：（1）当最终测试为线索回忆时,线索强度与学习策略交互作用显著,强线索条件下两组成绩差异不显著,弱线索条件下提取练习组显著高于精细加工组;（2）当最终测试为再认测验时,线索强度与学习策略在虚报率和目标词再认反应时上交互作用显著,精细加工组在弱线索条件下的虚报率显著高于强线索条件,在强弱线索条件下的目标词再认反应时差异不显著;提取练习条件组在强弱线索条件下的虚报率差异不显著,在强弱线索条件下的目标词再认反应时差异边缘显著,弱线索条件下反应时要比强线索条件下更长。上述结果表明材料的线索强度是区分提取练习与精细加工的重要变量,揭示了提取练习的内部加工机制不同于精细加工,反驳了精细提取假设,支持情景语境假设。     

Retrieval opportunities while multitasking improve name recall

In two experiments we tested whether providing retrieval opportunities while people were multitasking would improve memory for names. College students (n=195) in Experiment 1 did addition problems and intermittently were "introduced" to 12 face-name pairs to learn. For half the names students were given three within-list retrieval opportunities. Name recall (cued with the faces) was tested either immediately or after 24 hours. Retrieval opportunities improved name recall with both immediate and delayed tests. Experiment 2 more closely resembled the multitasking required in a real-life social situation. College students (n=98) viewed a videotape and were asked to learn the names of 12 dormitory residents who were introduced during an ongoing conversation. Retrieval opportunities were provided for 8 of the 12 residents by having them appear three additional times in the video without repeating their names. Retrieval opportunities improved name recall, but the effect was much smaller than in Experiment 1. The present research demonstrates that distributed retrieval can be effective when people are multitasking including when the multitasking involves a conversation.     

Providing corrective feedback during retrieval practice does not increase retrieval-induced forgetting

Recalling a subset of studied materials can impair subsequent retrieval of related, nontested materials. In two experiments, we examined the influence of providing corrective feedback (no feedback, immediate feedback, delayed feedback) during retrieval practice on this retrieval-induced forgetting effect. Performance was assessed with category cued recall (e.g., recall all exemplars studied under Weather), category-and-stem cued recall (e.g., Weather–B___), and recognition. We report a dissociation between the effects of feedback on memory of the tested materials and the nontested materials. Whereas providing immediate or delayed feedback (compared to no feedback) improved recall and recognition of the tested items, it had no influence on retrieval-induced forgetting. These results are consistent with the inhibition account of retrieval-induced forgetting. From an applied perspective, this finding is encouraging for students and educators who use testing to foster learning.     

The role of elaborations in learning a skill from an instructional text

In these studies, we examined the role of elaborations for subjects learning a procedural skill (viz., using a personal computer) from an instructional text. In Experiment 1, we compared two sources of elaborations: those provided by the author and those generated by learners while reading. In the latter condition, subjects were given advance information about the tasks they were to perform so that they would generate more specific task-related elaborations while reading. Each source of elaborations facilitated skill performance. This result contrasts with results of the past experiments testing declarative knowledge in which author-provided elaborations were found to hurt performance. In Experiment 2, the author-provided elaborations were classified into those illustrating the syntax of the operating system commands and those explaining basic concepts and their applicability. Syntax elaborations produced significant facilitation for experienced and novice computer users. Concept elaborations produced no reliable improvement.
