超常与常态儿童记忆和记忆监控的比较研究

本实验以超常儿童(20名,平均年龄为11岁2个月)和常态儿童(20名,平均年龄为11岁3个月)为被试,以数字和图形为实验材料对超常儿童和常态儿童的记忆、记忆组织和记忆监控的特点和差异作了初步的比较研究,结果是:(1)超常儿童不仅在回忆量和记忆速度上比常态儿童优异,而且还表现在元记忆上比常态儿童发展得更好;(2)儿童的记忆和记忆监控之间的关系较为复杂,但作为记忆效果的一个重要方面,记忆速度与记忆监控之间有显著相关;(3)作为元记忆的组成元素,记忆组织和记忆监控之间有显著相关。     

11~14岁超常儿童与普通儿童问题解决能力的发展比较

以北京市某中学和某小学11~14岁之间294名学生为被试, 其中超常儿童131人, 普通儿童163人。采用推箱子任务, 结合横向比较和纵向追踪数据, 从认知能力、元认知能力和认知效率三个维度来考察超常儿童与普通儿童问题解决能力的发展差异。结果发现超常儿童在问题解决能力的三个维度上均优于普通儿童, 两类儿童问题解决能力的发展模式不一致：超常儿童的问题解决能力发展先快后慢, 快速发展期在11~12岁半之间; 普通儿童的问题解决能力发展先慢后快, 快速发展期在12岁半~14岁之间。超常儿童与普通儿童的问题解决能力差异随年龄增大逐渐减小。

Relationships between study organization, retrieval organization, and general and strategy-specific memory knowledge in young children

The present study examined relationships between young children's memory knowledge and their use of taxonomic and color memory organization. Forty-eight 5-, 6-, and 7-year-olds were administered metamemory tests of organization-strategy knowledge and general memory knowledge, and were tested on two study-recall tasks before, and two study-recall tasks after, training in the use of color or taxonomic organization. Study organization (grouping) scores were low before training, but improved significantly in post-training tasks. Training effects were less pronounced for retrieval organization (clustering) and did not occur for item recall. Relationships between taxonomic study and retrieval organization were apparent only for the 7-year-olds, while relationships between color organization at study and retrieval were not apparent at any age level. Relationships between metamemory, strategy-use, and recall proficiency were evident on some tasks for 7-year-olds, but not for younger children. Although teacher ratings of the children's mastery orientations were also found to be related to recall proficiency for the older subjects, specific strategy knowledge was a more consistent correlate of strategy use and amount recalled.     

Metamemory, memory performance, and causal attributions in gifted and average children

Fifth and seventh graders who had been teacher-selected as high- or average-achieving were tested on the Kognitiver F?higkeits Test, a standardized test of intellectual abilities for German children. Children who met preestablished criteria as gifted or average were then tested on measures of metacognitive knowledge, attributional beliefs, and performance on a sort recall task. Results indicated ability-related differences in metamemory and sort recall performances. Responses to the attributional questionnaires also varied systematically according to ability: gifted children were more likely to attribute their academic successes to high ability than were average children, who showed a stronger belief in the importance of effort in determining task outcomes. Causal modeling analyses illustrated the strength of metacognitive knowledge as a performance predictor on the memory task, especially for average children. Results are discussed in terms of the value of metacognitive theory in understanding individual performance differences.     

Metamemorial knowledge of good and poor readers: a developmental perspective

Torgesen (1977b) suggested that reading-disabled children exhibit passivity in learning situations; they fail to employ strategies that enhance learning. Such passivity resembles that of young children who lack awareness of the utility of strategies that enhance cognitive efficiency in a variety of situations (e.g., listening, reading, and memory tasks). Such awareness is one aspect of metamemory, and children with reading problems may lag behind other children with regard to this aspect. Good readers (second-, third-, and fifth-graders) and poor readers (third- and fifth-graders) were interviewed to determine their level of knowledge about a number of variables that affect memory in real-life situations. Each child was asked questions concerning his or her memory ability, and then was shown pictures depicting manipulations of the variables number, time, category, and strategy, as well as two-way combinations of the four variables. Results generally failed to support the developmental lag hypothesis. Poor readers did not resemble younger children in their awareness of variables that affect memory but exhibited knowledge commensurate with that of good readers in the same grade.

Developmental relationships among metamemory,elaborative strategy use,and associative memory

Two experiments examined the relationships among metamemory knowledge, the use of associative memory strategies like elaboration, and cued-recall memory. In Experiment 1, 5th and 12th graders verbalized their strategies while studying noun pairs; their cued-recall memory of those pairs was then tested. Metamemory knowledge was assessed before or after this task. ANOVAs revealed developmental increases in associative strategies, cued recall, and metamemory. Multiple regression indicated the increase in associative strategies predicted all but 4% of the increase in cued recall; metamemory development in turn predicted all but 4% of the increase in associative strategies. Metamemory was a better predictor than a nonverbal measure of intelligence. The strong relationships were due partly to methodological refinements, including a counterbalanced design, a direct strategy measure, a reliable composite rather than single-item metamemory measure, ordinal rather than dichotomous scoring of metamemory items, and regression rather than χ² analyses. The results of Experiment 1 were replicated in Experiment 2. Metamemory development also predicted most of the grade difference in cued recall that remained after study strategies were equated by elaboration instructions, suggesting it may explain improvements in retrieval strategies as well.

The emergence of strategic knowledge activation in categorical clustering during retrieval

Elementary school children's free recall clustering has recently been explained as an automatic by-product of their developing knowledge base. In contrast, it is claimed that as children get older they become aware of the usefulness of category organization as a memory strategy that enables them to strategically activate category knowledge even during retrieval. To test this hypothesis an experimental procedure was developed where Ss first had to learn items in a noncategorical order to the criterion of two perfect serial recall trials. After a 12- to 15-min retention interval Ss unexpectedly received either serial or free recall (or--in Experiment 1--cued recall) instructions. In three experiments with second and fourth graders it was shown that (1) fourth graders' recall exceeded that of second graders only in the free, but not in the serial (or cued), recall condition, (2) higher levels of clustering were observed for fourth graders in the free recall condition, and (3) the grade effect on free recall data was eliminated when the influence of metamemory and categorical clustering statistically was partialled out (Experiments 1 and 3). This pattern of results proved robust against variants in which a metamemory question was asked or omitted prior to recall (Experiment 2) and manipulations in which age differences in categorical knowledge were minimized (Experiment 3). The results were interpreted as demonstrating fourth graders' strategic competence in activating category knowledge during retrieval and second graders' automatic knowledge activation.
