The development of young children's memory strategies: Evidence from the Würzburg Longitudinal Memory Study

This article reports findings of the Würzburg Longitudinal Memory Study, which focused on children's verbal memory development. The study started with 100 kindergarten children who were tested on various memory measures, including sort-recall, text recall, short-term memory capacity, and metamemory. Assessments were repeated nine times, with adjacent measurement points separated by 6-month time intervals. The main goals of the study concerned the strategy acquisition process (gradual vs. abrupt), the assessment of utilization deficiencies, and the impact of multiple strategy use during the course of strategy development. Findings showed pronounced interindividual differences in strategy acquisition. However, semantic organization strategies were acquired rapidly (and not gradually) in most cases. Moreover, although strategy discovery was not always accompanied by superior recall, utilization deficiency problems were comparably rare throughout the course of the study. Multiple strategy use turned out to be important in that, from the very beginning onwards, those children who used two or more memory strategies substantially outperformed their peers who used fewer than two strategies.     

The development of young children's memory strategies: First findings from the Würzburg Longitudinal Memory Study

This article reports the first findings of the Würzburg Longitudinal Memory Study, which focuses on children's verbal memory development, particularly the acquisition of memory strategies. At the beginning of the study, 100 kindergarten children (mean age 6 1/2 years) were tested on various memory measures, including sort-recall, text recall, short-term memory capacity, and metamemory. Assessments were repeated twice, with adjacent measurement points separated by 6-month time intervals. One major goal of the initial phase of the study concerned the exploration of the utilization deficiency phenomenon, which refers to the fact that young children who spontaneously use a memory strategy for the first time do not experience immediate memory benefits. Results obtained for the sort-recall task showed that, among those children who acquired a sorting strategy between Times 1 and 2, only a small proportion experienced the utilization deficiency problem. Additional analyses demonstrated that these few children also performed more poorly on the short-term memory tasks and the text recall measure when compared with the groups of efficient strategy users, suggesting that utilization deficiency is accompanied by a more general memory capacity problem. Overall, the findings revealed enormous variability in the early acquisition of memory strategies, indicating that the utilization deficiency phenomenon might not be as frequent as is assumed in the relevant literature.     

Instructing Children to Use Memory Strategies: Evidence of Utilization Deficiencies in Memory Training Studies

Utilization deficiencies occur when children experience little or no benefit in task performance from the use of a strategy. Miller and Seier (1994) found evidence for utilization deficiencies in over 90% of memory studies that evaluated spontaneous strategy use in children. In this article, we extend the concept of utilization deficiency to training studies and review nearly 30 years of memory-training research. We identified three different types of utilization deficiencies and evaluated 39 different studies with 76 separate conditions for evidence of utilization deficiencies (increases in strategy use with little or no corresponding increase in memory), production deficiencies (increases inbothstrategy use and memory performance), and unsuccessful training (increases inneitherstrategy use nor memory performance). Over half of all training conditions showed evidence of at least one type of utilization deficiency. Utilization deficiencies were more common for younger than older children and were more likely to be found when training involved multiple procedures (e.g., verbal instruction, rationale) rather than a single procedure (instruction only). The findings are discussed in terms of the need to broaden the concept of utilization deficiency and to reevaluate the process of strategy development.     

A study of retrieval processes in action memory for school-aged children: the impact of recall period and difficulty on action memory

ABSTRACT

Research in action memory for adults has shown that enacted encoding is not only retrieved more frequently but is also faster in comparison to verbal encoding. The aim of this study was to investigate retrieval processes in terms of recall period and recall difficulty for different encoding conditions in school-aged children (8-, 10-, 12-, 14-years old). The participants studied verbal tasks, subject-performed tasks and experimenter-performed tasks, and received immediate and final free-recall tests. The results revealed that older children not only outperformed younger children in terms of accuracy but also outpaced them in all recall periods. Moreover, recalls of subject-performed tasks and experimenter-performed tasks were better and faster compared with verbal encoding on both types of recall test, by increasing throughout the recall periods. These results are discussed in terms of memory strategies and information processing methods. Pedagogic implications for the use of action memory in children's learning are also considered.     

The value of proactive goal setting and choice in 3‐ to 7‐year‐olds' use of working memory gating strategies in a naturalistic task

Rule‐guided behavior depends on the ability to strategically update and act on content held in working memory. Proactive and reactive control strategies were contrasted across two experiments using an adapted input/output gating paradigm (Neuron, 81, 2014 and 930). Behavioral accuracies of 3‐, 5‐, and 7‐year‐olds were higher when a contextual cue appeared at the beginning of the task (input gating) rather than at the end (output gating). This finding supports prior work in older children, suggesting that children are better when input gating but rely on the more effortful output gating strategy for goal‐oriented action selection (Cognition, 155, 2016 and 8). A manipulation was added to investigate whether children's use of working memory strategies becomes more flexible when task goals are specified internally rather than externally provided by the experimenter. A shift toward more proactive control was observed when children chose the task goal among two alternatives. Scan path analyses of saccadic eye movement indicated that giving children agency and choice over the task goal resulted in less use of a reactive strategy than when the goal was determined by the experimenter.     

Utilization deficiency and working memory capacity in adult memory performance: not just for children anymore

In acquiring mnemonic strategies, children may demonstrate a utilization deficiency phase in which they successfully execute a strategy but it does not facilitate memory performance. The present experiment suggests that utilization deficiencies are not a developmental phenomenon per se, but rather a byproduct of diminished working memory capacity for any reason (i.e., maturation, knowledge base, context, individual differences, etc.). Adults performing a series of study-test memory trials using nonsense words exhibited characteristics of utilization deficiencies, with increased strategy use not contributing to increased memory performance. Furthermore, adults’ working memory capacity modified the effect. Implications of these findings for developmental models of strategy acquisition are discussed.     

When Children's Knowledge of Memory Improves Children's Performance in Memory

One of the strongest hypotheses in the field of metacognition research involves the positive effect of metamemory on memory performance. However, owing to the lack of appropriate instruments to appraise knowledge of memory, few studies have examined this effect among children. This study was conducted to create and validate an instrument to assess children's metamemory knowledge and link this knowledge with their memory performance and strategy use. A sample of 166 children was given a new three‐factor metamemory interview, and its psychometric properties were investigated. Regression analyses were carried out to investigate the link between metamemory and memory performance in a subgroup of 128 children from the validation study. Results confirmed the scale's good psychometric properties and revealed its ability to predict children's memory performance. However, none of the scale's factors could predict children's use of memory strategies. Implications for the study of children's metamemory development are discussed.

Working memory as a predictor of written arithmetical skills in children: The importance of central executive functions

Background . The study was conducted in an attempt to further our understanding of how working memory contributes to written arithmetical skills in children. Aim . The aim was to pinpoint the contribution of different central executive functions and to examine the contribution of the two subcomponents of children's written arithmetical skills. Sample and method . A total of 141 third‐ and fourth‐graders were administered arithmetical tasks and measures of working memory, fluid IQ and reading. Regression analysis was used to examine the relationship between working memory and written arithmetical skills. Results . Three central executive measures (counting span, trail making and verbal fluency) and one phonological loop measure (Digit Span) were significant and predictors of arithmetical performance when the influence of reading, age and IQ was controlled for in the analysis. Conclusions . The present findings demonstrate that working memory, in general, and the central executive, in particular, contribute to children's arithmetical skills. It was hypothesized that monitoring and coordinating multiple processes, and accessing arithmetical knowledge from long‐term memory, are important central executive functions during arithmetical performance. The contribution of the phonological loop and the central executive (concurrent processing and storage of numerical information) indicates that children aged 9–10 years primarily utilize verbal coding strategies during written arithmetical performance.     

Own-age biases in verbal person memory

Two experiments examined own-age biases in younger adults', older adults', and children's verbal person memory. In line with findings from face recognition studies, Experiment 1 showed that younger adults had a better recall of own-age than of other-age targets, while older adults were unaffected by target age. Participants' self-reported interest in targets did not predict target memory. Experiment 2, which examined children's and younger adults' memory of own- and other-age targets, showed an own-age advantage in children's but not in younger adults' verbal person memory. Differences in expertise of own-/other-age targets, in combination with a development of expertise throughout the Hfespan, may account for the findings, although alternative explanations should be considered. Implications for theory and practice are discussed.     

Children's use of semantic organizational strategies is mediated by working memory capacity

In adults, the ability to apply semantic grouping strategies has been found to depend on working memory. To investigate this relation in children, two sort-recall tasks (one without and one with a grouping instruction) were administered to 6–12-year-olds. The role of working memory was examined by means of mediation analyses and by assessing whether children who successfully used the semantic grouping strategy had higher working memory capacity than did children who did not show such strategy use. Only children aged 8–12 were able to successfully use semantic grouping strategies (and 8–9-year-olds only after instruction), while strategy use was absent in 6–7-year-olds. Both types of analysis involving working memory suggested that, also in children, working memory (and not short-term memory) mediates the development of successful use of the semantic grouping strategy during both encoding and retrieval.     

Involvement of Executive Functions in Children's Metamemory

This experiment examined how knowledge of memory strategies and of memory functioning improves during childhood and what variables are involved in this development. Three main aspects of metamemory were assessed based on the performance of a group of 100 children (aged 4, 6, 9 and 11 years) on a battery of executive tasks. At the same time, the influence of variables such as intelligence, vocabulary and parental education level was also investigated. Results of mediation analyses reveal that the relation between children's age and internal strategy knowledge was partially mediated by working memory skills but that executive functions did not mediate the impact of chronological age on children's knowledge of external strategies or of memory functioning. Additionally, verbal fluency predicted internal and external strategy knowledge. Implications for general learning theories in childhood are discussed.Copyright © 2015 John Wiley & Sons, Ltd.     

Reasoning strategies: the role of working memory and verbal-spatial ability

Evidence increasingly suggests individual differences in strategies adopted on reasoning tasks and that these are either verbal-propositional or visuospatial in nature. However, the cognitive foundations of these strategies remain uncertain. Experiment 1 examined the relationship between the use of working memory resources and strategy selection for syllogistic reasoning. Verbal and spatial strategy users did not differ on working memory capacity, but confirmatory factor analysis indicated that while verbal reasoners draw primarily on verbal working memory, spatial reasoners use both this and spatial resources. Experiment 2 investigated the relationship between strategies and verbal and spatial abilities. Although strategy groups were similar in overall ability, regression analysis showed that performance on a spatial ability measure (Vandenberg mental rotation task) predicted syllogistic reasoning performance, but only for spatial strategy users. The findings provide converging evidence that verbal and spatial strategies are underpinned by related differences in fundamental cognitive factors, drawing differentially on the subcomponents of working memory and on spatial ability.     

Developmental changes in the engagement of episodic retrieval processes and their relationship with working memory during the period of middle childhood

We examined the development of children's engagement of the episodic retrieval processes of recollection and familiarity and their relationship with working memory (WM). Ninety‐six children (24 in four groups aged 8, 9, 10, and 11 years) and 24 adults performed an episodic memory (EM) task involving old/new, remember/know (R/K), and source memory judgements and numerous WM tasks that assessed verbal and spatial components of WM and delayed short‐term memory (STM). Developmental changes were observed in EM with younger children (8‐, 9‐, 10‐year‐olds) making fewer remember responses than 11‐year‐olds and adults while 11‐year‐olds did not differ from adults. Only children aged 10 years plus showed a relationship between EM and WM. EM was related to verbal executive WM in 10‐ and 11‐year‐old children suggesting that children at this stage use verbal strategies to aid EM. In contrast, EM was related to spatial executive WM in adults. The engagement of episodic retrieval processes appears to be selectively related to executive components of verbal and spatial WM, the pattern of which differs in children and adults.     

Representation and processing of words in memory in a Sternberg type scanning experiment

Summary Sternberg's (1969) model of memory scanning processes is considered to be insufficient for verbal material. In Sternberg's model no considerations are given to coding and decoding processes which are relevant for verbal material. Usually Ss will represent letter strings of words as one unit with a specific meaning. If Sternberg's model should be valid for verbal material the time for coding and decoding of the memorized material has to be considered in addition to the time of coding the test stimulus, comparing the test item with the items of the memorized list and responding. Experimental data with different tasks to find a letter or a word in a list of words or a letter in a word can be explained adequately if coding and decoding processes for words are considered in the Sternberg model.

---

Zusammenfassung Es wird davon ausgegangen, daß das Modell von Sternberg (1969) für Suchprozesse im Gedächtnis bei verbalem Material unzureichend ist. Die Besonderheit verbalen Materials besteht darin, daß es Vpn veranlaßt, physikalisch gegebene Buchstabensequenzen zu Wörtern zusammenzufassen, die als Bedeutungseinheiten codiert werden. Wenn man in dem Modell von Sternberg neben der Zeit für die Codierung des Testreizes, zum Vergleich des Testreizes mit einer memorierten Liste und zur Antwort zusätzlich die Zeit zur Codierung und Decodierung des memorierten verbalen Materials berücksichtigt, können experimentelle Daten zur Suche von Wörtern oder Buchstaben in Wortlisten adäquat erklärt werden.

Young children's transfer of strategies: Utilization deficiencies,executive function,and metacognition

The purpose of this review is to present a new perspective on children's development of transfer of learning. The focus is on transfer of the effectiveness of a skill (i.e., improved performance), rather than just the transfer of the skill (e.g., a strategy) itself. Specifically, we examined the role of strategy utilization deficiencies, along with cognitive capacity, in the transfer of a memory strategy and, especially, strategy effectiveness (increased recall). Executive functions, metacognition, and mindset were considered as mechanisms that can both facilitate and hinder transfer of strategy effectiveness. Implications for theorizing about both transfer and utilization deficiencies were discussed.

Children's prepared and unprepared lies: can adults see through their strategies?

We investigated adults' ability to detect children's prepared and unprepared lies and truths. Furthermore, we examined children's strategies when lying. Thirty children (11–13 years) were interviewed about one self‐experienced and one invented event each. Half had prepared their statements, the other half not. Sixty adult observers assessed the veracity of 10 videotaped statements each. Overall deception detection accuracy (51.5%) was not better than chance. The adults showed higher accuracy for unprepared statements (56.6%), than prepared statements (46.1%). The adults reported to have used more verbal than nonverbal cues to deception, especially the Detail criterion. The most frequent verbal strategy reported by the children was to use real‐life components (e.g. own or others' experiences); the most frequent nonverbal strategy was to stay calm. Arguably, the low accuracy is due to adults' failure to see through the lying children's strategies. Copyright © 2006 John Wiley & Sons, Ltd.     

Young children's spontaneous utterances of mental terms and the accuracy of their memory behaviors: a different methodological approach

The purpose of this study was to determine whether young children's spontaneous utterances of mental terms would be congruent with the accuracy of their memory behaviours, and whether the use of an incidental memory task would yield similar developmental patterns as other methodologies. It was hypothesized that if children realize that internal mental activities influence behavioural actions, then the children's behavioural actions (recall) would be congruent with their utterances. A total of 27 three‐ and five‐year‐old children spontaneously used cognitive verbs such as knowing, forgetting, remembering, thinking, guessing and betting during a recall task. The results revealed that 39% of the 3‐year‐old children's behavioural responses and 67% of the 5‐year‐old children were congruent with their spontaneous utterances. These and other findings were consistent with studies that utilized different methodologies. Copyright © 2002 John Wiley & Sons, Ltd.     

Effects of Motivation on Young Children's Object Recall and Strategy Use

The study was designed to examine the effects of motivation on young children's recall for object names and early-emerging mnemonic activities. Seventy-two 4-year-old children were randomly assigned to 1 of 3 instructional conditions: incidental, intentional, or motivational. Each child was shown 10 small toy objects and provided a 90 s study period prior to recall. The children's mnemonic behaviors were videotaped for subsequent coding. The children in the incidental condition were instructed to simply look at the toys while children in the intentional and motivational condition were given explicit instructions to remember. The motivational group was also told that they could keep whichever toys they remembered. A recognition memory task was employed to examine the extent to which the stimuli were encoded during the study period. The children's recall memory did not vary as a function of instructional condition. Children's use of singular versus multiple strategies was calculated, along with a weighted summary score giving most weight to the participant's use of mature mnemonic strategies. Significant differences in strategy use were found, favoring the motivational condition. Significant positive correlations were found between the weighted summary scores and object recall, and the teacher ratings of mastery motivation and object recall. Mastery motivation was found to be unrelated to the strategic summary scores, failing to mediate strategic behaviors. The results suggest that when providing incentives to remember, children apparently engaged in more effortful mnemonic processing in order to remember the items, even though a greater number of items were not recalled.
