Training and Extension of a Memory Strategy: Evidence for Utilization Deficiencies in the Acquisition of an Organizational Strategy in High- and Low-IQ Children

143 9- and 10-year-old children were classified into high- and low-IQ groups and given 4 different sort/recall lists (baseline, training, near [immediate] extension, far [1-week] extension) to assess training and extension of an organizational memory strategy. All children received categorized items of moderate typicality for Phases 1, 3, and 4. For Phase 2, children were assigned to either a training or control group, with half of the children in each group receiving category typical items and the others category atypical items. Levels of recall, sorting, and clustering were greater in Phase 2 for high-IQ children, for the typical lists, and for trained children. Both the high- and low-IQ children trained with typical items continued to show high levels of recall on the near extension phase. No group of subjects maintained high levels of recall after 1 week, although levels of sorting and/or clustering on the extension trials remained high for all groups of subjects except the low-IQ control children. This latter pattern (elevated sorting/clustering with low levels of recall) is an indication of a utilization deficiency , a phase in strategy development when children use a strategy but gain little or no benefit in performance. The results provide evidence for IQ, training, and material effects in the demonstration of a utilization deficiency.     

Private speech and strategy-use patterns: bidirectional comparisons of children with and without mathematical difficulties in a developmental perspective

The present study examines private speech and strategy-use patterns for solving simple number fact problems in addition. The progressive differentiation by grade between children's levels of private speech internalization--including silence--was investigated and related to children's developmental patterns for subcategories of strategy-use internalization. Comparisons were made between 67 children with math difficulties (MD) and 67 children without MD from Grade 2 to Grade 7 in primary schools. Two separate laboratory investigations were performed for each child to examine private speech and strategy-use internalization. Analysis was based on private speech category differences, strategy-use differences, and differences in the occurrence of private speech-strategy-use combinations. Children without MD showed a grade-determined shift from less to more internalized private speech and from the use of backup strategies to retrieval strategies. In contrast, the private speech and the strategy-use internalization of children with MD, reflected in inaudible private speech and backup strategy use, seemed to converge at earlier developmental levels. The development of children with MD seemed almost to stop at the inaudible private speech-backup strategy combination level. The silence-retrieval strategy combination level was the primary alternative for typical math achievers. In all, the characteristics of the development curves of the children with MD were consistent with a developmental difference and not with a developmental delay model. Implications for intervention and future research methodology are discussed.     

Progress in the inductive strategy-use of children from different ethnic backgrounds: a study employing dynamic testing

This study investigated potential differences in inductive behavioural and verbal strategy-use between children (aged 6–8 years) from indigenous and non-indigenous backgrounds. This was effected by the use of an electronic device that could present a series of tasks, offer scaffolded assistance and record children’s responses. Children from non-indigenous ethnic backgrounds, starting at a lower level, profited as much from dynamic testing as did indigenous children but were unable to progress to the standard of this latter group. Irrespective of ethnic group, dynamic testing resulted in greater accuracy, fewer corrections, and reduced trial-and-error behaviour than repeated practice. Improvements in strategy-use were noted at both the group and individual level. After dynamic training, children from both ethnic groups showed a superior capacity for inductive reasoning although indigenous children subsequently used more inductive strategies. The study revealed individual differences between and within different ethnic groups and variability in the sorts of help required and subsequent strategy progression paths.     

The development of children's strategies for selective attention: evidence for a transitional period

Previous research suggests a developmental lag between producing a strategy of selective attention and benefiting from it. This aspect of the transitional period during strategy acquisition was investigated in the present study by comparing recall following child-produced (Session 1) and experimenter-produced (Session 2) strategies. The 114 7-9-year-olds were told to remember a subset of 6 items (either animals or household) located beneath 2 rows of doors. Session 1 assessed each child's spontaneous strategy (pattern of opening doors) over 6 trials. Session 2 included 7 different trial types, during which the experimenter opened the doors, thereby equating the strategies for children of all ages. The results revealed gradual changes in children's ability both to produce and to benefit from a selective strategy. Whereas younger children performed differently on trial types during which only the 6 relevant versus all 12 items were shown, older children recalled a similar number of items for all trial types, regardless of the number or pattern of door openings provided. Adult-produced selectivity eliminated recall differences among the grades and suggested that strategy production is effortful for younger children and therefore may prevent their benefiting from the strategy.     

Giftedness and variability in strategic processing on a multitrial memory task: Evidence for stability in gifted cognition

This study examined strategic variability and variability-performance relations in intellectually gifted (mean IQ = 142.31; n = 85) and non-gifted (mean IQ = 112.44; n = 81) children who received five trials on an organizational memory task. Children were presented with different sets of categorizable words (e.g., boat, bus, car, banana, apple, orange) on each trial and were asked to remember the words for later recall. Four strategies were coded on each trial: sorting at study, rehearsal, category naming, and clustering at recall. Strategic variability was assessed in terms of fluctuations in the use of single strategies over trials, use of different combinations of multiple strategies over trials, and trial-bytrial switches in strategy use. In general, gifted children showed lower levels of variability (or higher levels of stability) in strategy use and higher levels of recall than non-gifted children. In addition, stability in strategy use was consistently associated with relatively high levels of recall for gifted but not non-gifted children. These findings confirm and extend research on non-strategic elementary cognitive tasks showing that cognitive stability is a prominent characteristic of gifted cognition.     

Relationship between single digit addition strategies and working memory reflects general reasoning sophistication

With age, children employ increasingly more sophisticated strategies to solve single-digit addition (SDA) number fact problems. Changes in SDA strategy-use are correlated with age-related changes in cognitive measures (e.g., working-memory capacity, WM); however, this correlation does not explain the basis of SDA strategy-use or change per se. Does strategy-use reflect differences in generally reasoning abilities or are they uniquely tied to SDA abilities? Answers to these questions would help clarify the nature of SDA abilities specifically and early math abilities more generally. To investigate these issues, we assessed 144 5- to 9-year-olds' SDA strategies, visuospatial working memory (VSWM), verbal WM, non-verbal IQ, basic RT, and visuospatial reasoning abilities. We focused on these abilities since recent research shows visuospatial processes support early math development. We used latent profile/class analysis to classify children's SDA strategies and visuospatial reasoning abilities, which yielded four ability subgroups in both cases, only partially related to age. Findings show SDA strategy subgroup and general reasoning subgroup memberships were related. More sophisticated subgroups had better WM, but did not differ in IQ and RT. Findings suggest SDA reasoning reflect general reasoning abilities. Implications for math skills acquisition and intervention are discussed.     

Task Dependency and the Role of Category Typicality and Metamemory in the Development of an Organizational Strategy

Second and fourth graders received 1 of 3 lists of items differing in category representativeness in either a free recall or a sort-recall task. The selection of list materials permitted a separation of the effects of age differences in category knowledge from those of that knowledge per se on children's recall behavior. Proximal and distal measures of metamemory also were derived. Levels of recall and clustering were superior in the sort-recall task and for items of high category typicality. Recall also increased with age, while grade effects for clustering were restricted to the sort-recall/high typicality condition. The deliberate use of an organizational strategy increased with items' category typicality and with age, and was more frequent in the sort-recall than in the free recall task. The results were interpreted as supporting the hypothesis that most 10-year-olds are capable of strategically activating category knowledge in appropriate task environments when items of high category typicality are provided.     

Memory strategy development: do we need yet another deficiency?

Recent discussions of strategy development have included the introduction of the concept of utilization deficiency. The present analysis examines the definition of utilization deficiency vis-à-vis the older contrasts between mediation and production deficiency and assesses the logical clarity of the current definition. Further, because utilization deficiency focuses on the transition from initial to proficient strategy use, the present analysis considers all of the possible types of strategy inefficiencies and evaluates whether the current definition of utilization deficiency precludes consideration of important strategy inefficiencies that have been documented in the existing literature and are likely to form the bulk of yet-to-be discovered inefficiencies. Although the emphasis on strategy inefficiencies is welcomed, the current analysis concludes that there are serious problems with the current definition of utilization deficiency, problems that both obscure important theoretical distinctions of the past and limit the investigation of strategy inefficiencies that are likely to play an important role in our understanding of the development of strategy use. Furthermore, the linear developmental model that frames utilization deficiencies from no benefit to sophisticated strategy use ignores the heterogeneity in strategy development that has been recently documented.     

A Study of the Influence of Some Factors in Style of Composition on the Interest,Comprehension, and Rate of Reading of Fourth-Grade Pupils

The research hypothesis was that memory strategy deficits can occur because of students' failure to understand the task and to evaluate their own performance. The effect of performance feedback on memory strategy use, performance evaluation, and recall was assessed with students with and without mild mental retardation with a mental age of approximately 8.5 years. For students with retardation, feedback resulted in more accurate performance evaluation and recall, but memory strategy use did not increase. By contrast, for students without retardation, feedback resulted in more accurate performance evaluation and greater recall accuracy and memory strategy use. We concluded that students with retardation may not have the appropriate memory strategies in their repertoire and, therefore, feedback does not result in strategy use. It seems likely that memory strategy use in this population would be increased by a training package that includes strategy instruction as well as feedback.     

Strategic and nonstrategic factors in gifted children's free recall

The present experiment contrasted the recall of gifted and nongifted middle-school children for sets of categorically related items. Subjects were given a single free-recall trial on each of two lists consisting of category-typical and category-atypical words. The typicality of the items for one list was based on each subject's unique typicality ratings, whereas the typicality of the items in the second list was based on adult norms. A preliminary category-rating task indicated that gifted students were somewhat more similar to adults in their ratings of category typicality than nongifted children. Recall was comparable between the gifted and nongifted subjects for typical items, but greater for the gifted subjects for atypical items. The latency between the recall of unrelated words was faster for the gifted than the nongifted children. Subjects were classified as strategic or nonstrategic on the basis of clustering and interitem latencies. Gifted subjects were less apt to be classified as strategic than nongifted subjects on the typical items of the self-generated list; there were no differences in the classification between the gifted and nongifted children for all other contrasts. These results were interpreted as indicating that the cognitive advantage of gifted relative to nongifted children is more apt to be in terms of nonstrategic rather than strategic functioning.     

The role of private speech in the transition from collaborative to independent task performance in young children

This study was designed to examine the following central Vygotskian hypotheses about the functions of preschool children's private speech: (1) that private speech facilitates the transition from collaborative to independent task performance, and (2) that children's use of private speech is conducive to task success. Age-related changes in children's use of private speech were also examined. Forty preschoolers, ranging in age from three to five, completed a selective attention task with scaffolded assistance given from an experimenter when needed. In an effort to overcome several methodological limitations found in previous research, a new microgenetic method of analyzing speech-performance relations based on assigning task items to discrete categories reflecting six possible co-occurrences between private speech (item-relevant speech, item-irrelevant speech, silence) and performance (success, failure) was introduced. Results were that (1) item-relevant speech was used more often during successful than during failed items while the opposite was true for item-irrelevant speech; (2) children were more likely to use private speech on successful items after scaffolding than they were on similar items not following scaffolding; (3) after scaffolding, children were more likely to succeed on the next item if they talked to themselves than if they were silent; and (4) hypothesized curvilinear, age-related patterns in children's item-relevant private speech and silence were found, however, only when analyzing speech during successful items. Implications of this research for preschool teachers and parents are discussed.     

Variable memory strategy use in children's adaptive intratask learning behavior: developmental changes and working memory influences in free recall

Variability in strategy use within single trials in free recall was analyzed longitudinally from second to fourth grades (ages 8-10 years). To control for practice effects another sample of fourth graders was included (age 10 years). Video analyses revealed that children employed different strategies when preparing for free recall. A gradual shift from labeling to cumulative rehearsal was present both with increasing age and across different list positions. Whereas cumulative rehearsal was frequent at early list positions, labeling was dominant at later list portions. Working memory capacity predicted the extent of cumulative rehearsal usage, which became more efficient with increasing age. Results are discussed in the context of the adaptive strategy choice model.     

Metacognition and control of study choice in children

Middle childhood may be crucial for the development of metacognitive monitoring and study control processes. The first three experiments, using different materials, showed that Grade 3 and Grade 5 children exhibited excellent metacognitive resolution when asked to make delayed judgments of learning (JOLs, using an analogue scale) or binary judgments of knowing (JOKs, ‘know’ or ‘don’t know’) without the target being present. (The delayed method used here also results in excellent metacognitive resolution in adults). In three subsequent experiments after making JOLs the children were asked to choose which items they would like to restudy to optimize learning. We then either honored or dishonored the children’s restudy choices, and tested their memory performance. In Experiment 4, honoring the children’s choices made no difference to final recall performance. Experiments 5 and 6 showed that when the computer, rather than the children, chose the items for restudy based on theoretical constraints proposed by the Region of Proximal Learning model of study time allocation, the children’s recall performance improved. In all three experiments, Grade 3 children’s choices were random. Whereas the Grade 5 children showed some indication of a metacognitively guided strategy of choosing the lowest JOL items for study, it did not, consistently, improve performance. Apparently, accurate metacognitive monitoring is largely in place in middle childhood, but is not yet converted into effective implementation strategies. This dissociation between metaknowledge and its implementation in choice behavior needs to be taken into account by educators aiming to design interventions to enhance learning in children at this age.     

Some Verbal Aspects of the 1937 Revision of the Stanford-Binet Intelligence Test,Form L

The authors examined an activity-based listening strategy with first- and third-grade children in mixed-grade dyads. On the basis of theories of cognitive development and previous research, the authors predicted the following: (a) children in an activity-based strategy would recall more story events compared with those in a repetition strategy and (b) children who performed activity would recall more events compared with those who observed activity. In addition, previous visual imagery research suggested that (c) recall in favor of the activity-based strategy would be observed when the toys were removed and imagery instructions were provided. The results confirmed the first prediction that the activity-based strategy would improve children's memory for story content. The second prediction was not supported: Physical manipulation did not improve memory beyond observing the actions performed by a peer. Last, third-grade students benefited from imagery instructions after training, whereas first-grade students did not. The authors discuss the theoretical and education implications of the results.     

The Benefits of Peer Collaboration: A Replication with a Delayed Posttest

The benefits of peer collaboration on strategy use, metacognitive causal attribution, and recall were supported in an earlier study (Manion & Alexander, 1997). Following that study two primary questions remained: Would the observed benefits last beyond an immediate posttest, and would they last regardless of which strategy the children chose to use? The current investigation explores those questions. Thirty-one fourth-grade students from two public schools in Sydney, Australia, experienced either a peer-collaborative treatment condition or an individual task (control condition). A posttest was conducted 5.5 weeks later. As was the case in the original study, children in the treatment condition outperformed children in the control condition in strategy use, metacognitive understanding of strategy chosen, and recall gain. Benefits also sustained regardless of the strategy children chose to implement on the task. Most importantly, the benefits lasted after a period of over a month. Implications for future research are discussed.     

Children's recall of medical experiences: the impact of stress

OBJECTIVE: The study compared children's reports of two medical events, to assess the effects of the type of event on children's recall. Additionally, the study examined the effect of props on children's event reports. METHOD: Twenty children between the ages of 37 and 67 months were interviewed following either a voiding cysto-urethrogram (VCUG) or a pediatric assessment (PA) at a hospital. Interviews were conducted between 6 and 8 days after the event and included a doll and prop items. RESULTS: Ratings of stress were significantly higher for children who underwent the VCUG than those who underwent the PA. Children who experienced the VCUG procedure reported more correct information than the children who experienced the PA. Age was correlated with the total amount of correct information reported. Stress levels were correlated with both errors and accuracy of information. CONCLUSIONS: Children who experienced a stressful medical procedure remembered more than children who experienced a neutral medical event, although this increase in amount recalled was at the expense of accuracy. These findings suggest that stress impacts negatively on recall: however, the unique and structured nature of the VCUG procedure compared to the PA, and the familiarity of the PA prop items to the children who experienced the VCUG procedure, may also have contributed to differences in recall of the two events.     

Retrieval Cues On Tests: A Strategy for Helping Students Overcome Retrieval Failure

Students often struggle to recall information on tests, frequently claiming to experience a “retrieval failure” of learned information. Thus, the retrieval of information from memory may be a roadblock to student success. I propose a relatively simple adjustment to the wording of test items to help eliminate this potential barrier. Specifically, I examined whether embedding salient information from class lectures in test items as retrieval cues enhanced student performance on tests. In two studies, including both an upper- and lower-division course, student performance on identical test items with and without retrievals was compared. Student performance varied significantly depending on whether retrieval cues were embedded in the items, and in both courses the difference was at least a half letter grade (study 2) or more (study 1). These results suggest that the selective use of retrieval cues on tests may be an effective strategy for helping students overcome retrieval failure on tests.     

Individual differences in children's ability to profit from picture adjunct aids

A paired-associate memory task with pictures and words as items was used to categorize fourth graders into four learner types: HH, high picture-high word; HL, high picture-low word; LH, low picture-high word; LL, low picture-low word. Some children in each classification read prose passages with picture adjunct aids; other children read the passages without adjunct aids. Although free recall for the prose passage yielded inconclusive data, a constructed response test for facts in the prose passages revealed significant Aptitude × Treatment interactions, such that poor paired-associate learners (i.e., LLs) profited more than did good paired-associate learners (i.e., HHs) from picture aids on the prose task. The children's standardized reading scores were positively related to memory performance, but good and poor readers did not differ in their ability to profit from picture aids. It was suggested that less-strategic learners, such as those who perform poorly on paired-associate tasks, are more likely to be helped by externally provided mediational aids, while more-strategic learners are more likely to be helped by instructions to generate their own mediational aids.
