Poetry as a Mnemonic Prompt in Children's Stories

This research investigates the effects of prosody on children's recall for stories using two successive studies. Study 1 is an ethnographic exploration of a group of fifth graders creating summaries of a children's story with overt prosodic elements. Study 2 is a quasi-experiment in which the story summaries created by students who heard one of two versions (more or less prosodic) of the story from Study 1 were compared. Overall, we find that the amount of prosody in a story has a significant effect on children's story recall and the quality of the stories they produce.     

Remembering Numbers in Old Age: Mnemonic Training Versus Self-Generated Strategy Training

The effectiveness of two memory training programs designed to enhance four-digit number recall was examined in 90 healthy older adults. One group received instruction and training in the number-consonant mnemonic, whereas another group was instructed to adopt their own encoding and retrieval strategies to enhance number recall. Also, a control group receiving no training between testing occasions was included. The criterion task was administered according to the Buschke selective reminding procedure. Posttest performance was evaluated with and without cognitive support for remembering (i.e., verbal cues). Under unsupported conditions, the mnemonic group improved number recall following training and the self-generated strategy group showed a tendency in the same direction. When support was provided, group differences in favor of the two training groups increased. In addition, no training-related gains were observed in two verbal transfer tasks. The relatively similar patterns of gains in the two intervention groups were discussed in terms of advantages and disadvantages in the two training regimens balancing each other.

The aim of our study is to examine the interface between children's physiological changes and the specificities of parental conflict, and to develop a procedure in which such information can be shared with the family for therapeutic change. Children from 20 families were exposed to parental conflict discussion (CD) while their arousals were measured through skin conductance and heart rate sensors. It was found that regardless of the subject of the argument, 80% of the time they were complaining about each other. Likewise, 80% of the time the children were responding to the parents' own interpersonal tension, including moments of silence. The protocol established for the study, consisting of CD and debriefing, was found to be a powerful tool in moving parents toward conflict resolution.     

Context Effects in Children's Selection and Use of Simple Arithmetic Strategies

Six- and 7-year-old children computed moves on a board game from dice over 3 sessions (game context) and also solved simple, aurally presented addition problems (academic context), corresponding to the dice rolls made in the game. Children displayed multiple and variable use of addition strategies in both the game and academic contexts, although there were significant differences in the strategies used and patterns of performance between the 2 contexts. Children used more sophisticated strategies and made more errors during the academic than the game context. The relation between strategy use, variability, and errors also varied between the 2 conditions, as did the selection of strategies children used for solving identical addition problems. These findings support selectionist models of cognitive development and illustrate the potent role of context in young children's strategy use.     

儿童对情绪表达规则的理解与策略的使用

从一所普通小学一三五年级学生中选取90名被试,结构访谈法考察儿童对情绪表达规则的理解与表达策略的使用。结果表明,儿童对情绪表达规则的理解在一到三年级阶段获得快速发展,三到五年级变化很小,而且在积极和消极情境下发展趋势比较一致,但性别和情境交互作用显著。不同年级儿童对策略的使用表现出类似对情绪表达规则理解的变化趋势,全部被试中,平静化策略使用最多,掩饰策略次之,在掩饰策略的使用上,性别和情境交互作用显著。     

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.     

Mnemonic Training for the Acquisition of Skilled Digit Memory

This article outlines a research strategy for investigating, in a laboratory setting, the acquisition and the "limits" of a cognitive skill. Expert digit memory is used as an illustration. Two participants with initial average digit-and word-span memory were trained to memorize and reproduce strings of 80 to 90 digits presented at 10- to 1-sec rates. The instruction and training program, based on a theory of skilled memory, focused on three components: (a) acquisition of a mnemonic system (i.e., recoding digits into historical dates or concrete nouns), (b) use of a long-term memory retrieval structure (i.e., instruction in the Method of Loci), and (c) improvement in processing speed. After 86 experimental sessions, one participant recalled 90 random digits presented at a 1-sec rate. The digits were, however, constrained to be compatible with the participant's historical knowledge. The second participant recalled 80 random digits presented at a 5-sec rate after 70 sessions. Speed of encoding and retrieval processing was the only component that required extensive practice for skilled digit-memory acquisition.     

Children's Response to Natural Map Misalignment During Wayfinding

Map-guided wayfinding requires updating the map-space relation whenever we turn. In 3 studies, children used a map to follow a path with two 90? turns. Although carrying the map, children rarely physically adjusted the map after turns. They performed well when the map was aligned with the space (on the 1st and 3rd legs), and they performed poorly on the 2nd leg when the map became naturally misaligned with the space. When map use was delayed (separating first viewing and first use), children still did not physically turn the map, but surprisingly, most performed well after both turns. We replicated this surprising finding with 2 age groups and examined individual differences. Children appear to use the map to anticipate the upcoming turn.     

Metamemory Experiments in Neurological Populations: A Review

Metamemory refers to knowledge about one's memory capabilities and strategies that can aid memory, as well as the processes involved in memory self-monitoring. Although metamemory has been studied in cognitive psychology for several decades, there have been fewer studies investigating the neuropsychology of metamemory. In recent years, a growing number of studies of neurological patient groups have been conducted in order to investigate the neural correlates of metamemory. In this review, we examine the neuropsychological evidence that the frontal lobes are critically involved in monitoring and control processes, which are the central components of metamemory. The following conclusions are drawn from this literature: (1) There is a strong correlation between indices of frontal lobe function or structural integrity and metamemory accuracy (2) The combination of frontal lobe dysfunction and poor memory severely impairs metamemorial processes (3) Metamemory tasks vary in subject performance levels, and quite likely, in the underlying processes these different tasks measure, and (4) Metamemory, as measured by experimental tasks, may dissociate from basic memory retrieval processes and from global judgments of memory.     

Fractal Characteristics of Response Time Variability

The relations between English spellings and pronunciations have been described as a fractal pattern. Manipulations of word properties are constructed to coincide with the fractal pattern of ambiguity in these relations (sampled as random variables). New word naming and lexical decision experiments replicate previously established effects of relations between word spellings and pronunciations. The structure of these relations establishes a measurement scale, which is nested in a manner that is loosely analogous to the way that centimeters are nested within meters, and so on. The experiments revealed that broader, increasingly stretched-more variable-distributions of pronunciation and response time accompany the introduction of higher resolution measurement scales to the naming and lexical decision measurement process. Moreover, the distribution of lexical decision response times is shown to obey an inverse power-law scaling relation, which implies lexical decision does not conform to a characteristic measurement scale.     

Early Developments in Children's Use of Counting to Solve Quantitative Problems

Two studies evaluated preschool children's use of counting to solve different kinds of quantitative problems. Three uses of counting were considered: (a) counting to quantify a single set, (b) counting to compare two sets, and (c) counting to generate a set of a specified numerosity. In Experiment 1, 3- and 3 1/2 year-olds tended not to count spontaneously when asked to compare two sets, even when they were able to count fairly well. In Experiment 2, 3 1/2 year-olds again tended not to count spontaneously on compare-sets and generate-set problems, although they did count readily on quantify-set problems; and the use of counting on the compare-sets and generate-set problems increased markedly between 3 1/2 and 4 1/2 years. These early developments may be important educationally because counting plays a major role in arithmetic learning.     

Children's Use of Generics in Inductive Inferences

Online comprehension of naturally spoken and perceptually degraded words was assessed in 95 children ages 12 to 31 months. The time course of word recognition was measured by monitoring eye movements as children looked at pictures while listening to familiar target words presented in unaltered, time-compressed, and low-pass-filtered forms. Success in word recognition varied with age and level of vocabulary development, and with the perceptual integrity of the word. Recognition was best overall for unaltered words, lower for time-compressed words, and significantly lower in low-pass-filtered words. Reaction times were fastest in compressed, followed by unaltered and filtered words. Results showed that children were able to recognize familiar words in challenging conditions and that productive vocabulary size was more sensitive than chronological age as a predictor of children's accuracy and speed in word recognition.     

Metamemory in temporal lobe epilepsy: Self-monitoring of memory functions

Temporal lobe seizure patients and control subjects participated in an investigation of metamemory. The two-part study explored the individual's perception of memory abilities for both encoding and retrieval. Experiment I addressed self-monitoring of encoding through a study of prediction of memory span. Experiment II explored self-monitoring of retrieval through a study of "Feeling of Knowing." The results indicate that left and right temporal lobe seizure patients tend to overestimate their memory capacities, in comparison with normal controls, and that self-monitoring tends to be less accurate for material (verbal or nonverbal) mediated by side of lesion. The potential impact of inaccurate memory monitoring on the memory dysfunction observed in seizure patients is discussed.     

Flexible Strategy Use in Young Children's Tic-Tac-Toe

In domains with multiple competing goals, people face a basic challenge: How to make their strategy use flexible enough to deal with shifting circumstances without losing track of their overall objectives. This article examines how young children meet this challenge in one such domain, tic-tac-toe. Experiment 1 provides an overviews of development in the area; it indicates that children's tic-tac-toe strategies are rule based and that new rules are added one at a time. Experiment 2 demonstrates that even young children flexibly tailor their strategy use to meet shifting circumstances. Experiment 3 indicates that these adaptations are accomplished through a process of goal-based resource allocation, whereby children focus their cognitive resources on applying rules most consistent with their current primary goal. A computer simulation specifies how this process works and demonstrates its sufficiency for producing behavior much like that of the children. The findings are discussed as part of a broader framework of mechanisms for generating problem-solving approaches.     

Boosting Children's Memory by Training Mothers in the Use of an Elaborative Conversational Style as an Event Unfolds

An experimental methodology was adapted to examine children's language skills and mothers' conversational styles during a specified event as they are linked to the children's event memory. Thirty-nine preschoolers (mean age = 46.82 months) were pretested and grouped as having high or low language skills. Children in each group were then randomly assigned to either maternal-style training or no training conditions. Trained mothers were instructed to use 4 specific conversational techniques to enhance children's understanding of unfolding events: Wh- questions, associations, follow-ins, and positive evaluations. When observed engaging with their children in a specially constructed camping activity, trained mothers did indeed use these elements of style more than untrained mothers. Moreover, assessments of the children's memory after 1-day- and 3-week-delay intervals indicated substantial effects of both maternal training and children's language skills on remembering.     

Rejection of False Events in Childhood: A Metamemory Account

ABSTRACT— Knowing how to identify events that we never experienced is an important skill: This ability enables us to reject such events as part of our past and thus reduces the risk of creating false memories. Recent research highlights the involvement of metamemory processes in this domain. I review empirical evidence pertaining to the functioning and development of the memorability-based strategy, a specific mechanism rooted in metamemory. The substantial development of this mechanism during childhood can provide an account for children's vulnerability to false-memory formation.     

Fast Mapping in Healthy Young Adults: The Influence of Metamemory

Several research studies suggest the significant role played by metamemory in lexical abilities of both adults and children. To our knowledge, there have been no studies to date that have explored the role of metamemory (Judgments of Learning) in fast mapping of novel words by adults. One hundred and twelve undergraduate students were given tasks of fast mapping and judgments of learning. A one-way Multivariate Analysis of Variance revealed that participants who performed well on fast mapping had superior global and item-by-item absolute prediction scores compared to poor performers. However, the good and poor performers did not significantly differ in their item-by-item relative predictive accuracy (Goodman–Kruskal gamma correlations) in the immediate as well as the delayed judgments of learning conditions. The possible reasons for inferior gamma correlations, the methodological issues for future research and the clinical implications for the assessment and treatment of adults with lexical deficits are discussed.
