This research examined the effects of a self-instruction intervention on the relationship between cognitive level and conceptual tempo. Preoperational and concrete operational children received the Matching Familiar Figures Test prior to and after serving in either a no training control group, a content only control group, or a self-instruction group. Children in the content only control group received the same set of self-guiding strategy statements as those in the self-instruction group but without overt rehearsal of the statements. Cognitive level and conceptual tempo were strongly related; preoperational children tended to be classified as impulsive, concrete operational chidlren, as reflective. Although cognitive level predicted overall performance, with concrete operational children being more successful and more reflective than preoperational children, the influence of training was similar for both groups. On posttest, children in the self-instruction groups made more correct responses and were more reflective than children in the other two training groups.  相似文献

Following a metamemory pretest, 60 first and third grade children (6 and 8 years of age, respectively) were divided into three treatment groups which received task-specific strategy instructions appropriate for three memory problems, general metacognitive information about subordinate and superordinate processing, or both strategy and metacognitive training. Maintenance and generalization versions of the memory tasks were given, followed by an attributional assessment of children's perceptions of the causes for specific success and failure outcomes. Post-training scores on the memory tasks showed that strategy training was highly successful. Metacognitive training appeared to have no effect on the metameory or strategy scores with one exception: metamemory and strategy use on the generalization task were significantly correlated only for children who received both metacognitive and strategy training. Apparently, children who were initially high in metamemory skills profited more from the comprehensive training package, using new metacognitive insights to aid the generalization of acquired strategies to the transfer tasks. Among strategy-trained children those who attributed success to effort were both more strategic and higher in metamemory than those who attributed task outcomes to noncontrollable factors such as ability or task characteristics. Results were discussed in terms of the interactive nature of knowledge, process, and motivational variables as determinants of strategy transfer.  相似文献

Forty-eight preoperational and concrete operational first and second graders performed on a training task (Matching Familiar Figures Test) and a generalization task (a perceptual perspective taking task) prior to, and after serving in, one of two instructional groups. The instructional groups were: a no-training control group and a group which received general content self-instructions delivered through a directed discovery procedure. Both preoperational and concrete operational children in the self-instruction group improved significantly at posttest on the training task. On the generalization task only the concrete operational children in the directed discovery group performed significantly better following training. These findings are discussed in terms of the dynamic relationship between an individual's cognitive ability and the format of instructions. The need for provoking the cognitive involvement of the child on the basis of this relationship is stressed.  相似文献

Groups of 60 preoperational and 60 concrete operational kindergarten children received stimulus differentiation training either with feedback (experimental groups) or without (control groups), prior to a series of discrimination-learning problems in which a blank-trial probe, used to detect the child's hypothesis, followed each feedback trial. The concrete operational children manifested significantly better performances than the preoperational on seven of eight dependent measures examined. There were also significant differences in favor of the experimental groups on three dependent measures. While the results were generally consistent with predictions derived from Piagetian stage theory, it was suggested that this theory must be elaborated to include a perspective derived from conventional developmental learning theory in order to adequately account for these and other data.  相似文献

This study investigated the impact of training 9 first- and second-grade children to use a full self-instructional regimen, and then differentially reinforced the use of self-instruction only, accuracy only, or both self-instruction and accuracy. Three comparison children received no training in self-instruction and were reinforced for accuracy only. Children improved dramatically in academic accuracy subsequent to self-instructional training, independent of the use of self-instruction and of the specific behavior consequated. Children who were reinforced for using self-instruction did use self-instruction, and those who were not, did not. Comparison group children showed little improvement until training in problem-solving strategies was given after 9 days of reinforcement for accuracy. Self-instructional training is discussed as one type of event that increases the likelihood of accurate performance. Its effectiveness may be explained in terms of a teaching strategy rather than in terms of modifying cognitive processes.  相似文献

Two experiments were designed to test the effects of self-instructional procedures on the academic performance of educationally handicapped children. Self-instructional training consisted of general self-instruction components coupled with explicit instruction in task components. Experiemnt 1 included two severly educationally handicapped children in which self-instruction training for reading comprehension and spelling was assessed. Generalization of training effects was evaluated across person, task, and setting Experiment 2 included one child in which self-instructional training for mathematics and generalization to a classroom setting was evaluated. A multiple baseline design was used in Experiment 1 and a reversal design in Experiment 2 to assess treatment effects. For both experiments, self-instructional training improved academic performance. Generalization occurred across person and task in Experiment 1 and setting in Experiment 2. It was concluded that successful academic performance occurs when self-isntructional statements integrate global strategies while simultaneously directing attention to task specific information.  相似文献

The present study examined the effectiveness of two components (rehearsal training and strategy awareness) of an instructional package designed to train the developmentally young in the use of mature information processing techniques. Two groups of children of equivalent developmental age (MA = 8), one mildly retarded and the other of average intelligence, participated. Rehearsal training was effective in improving recall scores on the training task; however, neither rehearsal training, memory awareness, nor their combination significantly altered memory performance on the generalization tasks. There was evidence, however, that the combination of rehearsal training and strategy awareness did increase the likelihood of strategy transfer on the generalization task (recognition) which most closely resembled the training task. Post-task questioning revealed that instructions concerning memory awareness did improve subjects ability to verbalize appropriate strategic behavior; however, these improvements were not consistently translated into either actual use of a rehearsal strategy or improved performance. Discussion centered on the implications of these results and on the need for increased research on the metamnemonic skills involved in strategy generalization.  相似文献

Differences in performance between lower- and middle-class children on partial reinforcement tasks have often been attributed to motivational differences between the groups. An alternate hypothesis suggests that different environmental experiences have resulted in differences in familiarity with problem-solving tasks. Both of these hypotheses have generated research; neither has received clear-cut support. A third hypothesis is that there is a developmental lag in the lower class so that equating the two groups on chronological age confounds the social class by cognitive-level interaction. In the present study, children were matched on cognitive abilities (preoperational, transitional, and concrete operational) and administered a partial reinforcement task. The main hypotheses that social-class differences would not be found but that cognitive level differences in success on the task and in problem-solving strategies would be found were supported. Implications were made concerning a developmental learning model that includes both qualitative and quantitative changes in abilities.  相似文献

Kindergarten and first-grade children (6 and 7 years of age, respectively) were given specially designed discrimination tasks with introtact probes preceding each trial. One group (CON) was given the criterion task without prior training. A second group (LTL) received three pretraining tasks of the same type as the criterion task. A third group (HYP) received the same pretraining tasks, but with explicit instructions designed to teach a simple hypothesis-testing strategy. Several indices, designed to reflect the use of win-stay and lose-shift rules, as well as memory for disconfirmed hypotheses, were computed from the protocols of the criterion task. The indices for Group CON suggested that most of these children were using a guessing strategy that involved quite frequent changes in hypotheses. Moreover, many of these children restricted their hypotheses to the irrelevant cues. The indices for Group LTL revealed a spontaneous use of the hypothesis-testing strategy by nearly half of the children. The results for Group HYP indicated that over four-fifths of these children became highly efficient in the use of the problem-solving strategy.  相似文献

Children, 3, 4, 5, 6, 8, and 10 years old, were randomly divided into three training conditions—a strategy modeling condition, a strategy modeling with overt self-verbalization condition, and a control condition. The subjects in the two modeling conditions were given training on four cognitive tasks, a signal task, a match-to-standard task, a paired-associates task, and a twenty-questions task. A 6 (age) × 2 (sex) × 3 (treatment) × 2 (trial) analysis of variance was performed on each of the dependent variables associated with each of the four tasks. The results of these analyses indicate that both modeling conditions facilitated performance on the signal and match-to-standard tasks for all six age groups. However, the two modeling procedures facilitated performance on the paired-associates and twenty-questions tasks only in the three older age groups. Since the two modeling procedures did not differ in effectiveness, it was suggested that strategy modeling without overt self-verbalization is the more practical and efficient procedure for facilitating cognitive performance in normal children.  相似文献

This study examines the effectiveness of an integrative imagery strategy in contrast to more concrete enaction and repetition strategies for improving kindergarten children's recall of pictograph sentences. The training groups were taught in two brief sessions to read the pictograph sequences as sentences and then to imagine the sentence's action (sentence imagery), act out the sentence using toys (sentence enaction), or repeat each sentence twice (sentence repetition). After training, the enaction group significantly outperformed the imagery and sentence repetition groups, which outperformed a repetition control group. Two weeks later, the imagery and enaction groups no longer differed significantly in recall and both groups significantly outperformed the repetition control group. The imagery group alone significantly outperformed the repetition control group on a no-toys generalization test. Implications of the results concerning strategy training of young children, the effectiveness of imagery strategies, and experimental design are discussed.  相似文献

We compared the effects of the effects of self-instructions in the form of prose or song lyrics in the acquisition of gross motor tasks in 4 third-grade children. We taught participants 4 pairs of gross motor tasks, with one task in each pair taught with prose self-instructions and the other taught with song lyric self-instructions. Both self-instruction procedures were effective for teaching tasks; however, acquisition was quicker with song lyric self-instruction for 4 task pairs, acquisition was quicker with prose self-instruction for 3 task pairs; and similar for 1 task pair. Participants were then able to select their preferred method of self-instruction for a novel, applied skill. Two participants selected song-lyric self-instructions and 2 participants selected prose self-instructions.  相似文献

Performance on two different task combinations was examined for evidence that timesharing skills are learned with practice and can transfer between task combinations. One combination consisted of two discrete informaion processing tasks, a short-term memory task and a classification task; the other consisted of two identical one-dimensional compensatory tracking tasks. Three groups of 16 subjects were employed in the experiment. The first received dual-task training on both combinations; the second received single-task training on the discrete-task combination and dual-task training on the tracking combination; the third received dual-task training on the tracking combination only. Evidence for distinct timesharing skills was found in both combinations using a new technique designed to separate improvements in timesharing skills from improvements in single-task performance. Transfer of timesharing skills also was found. Several fine-grained analyses performed on the data from the discrete task combination and a Control Theory Analysis of the tracking data indicated that skills in parallel processing were learned in each combination and transferred between them.  相似文献

The spontaneous or induced use of an organization strategy is examined on free recall tasks with 10-year-old children classified as rather global or rather analytical at the Group Embedded Figures test. The experimental procedure include three successive and identical tests followed by two deffered tasks, one requiring a transfer of maintenance and the other a transfer of generalization. The experimental group, who attended a simple illustration of the organization strategy before the second test, applied the strategy quickly and successfully: for these subjects, one does not note differences between global or analytical subjects in the recall performance; however, the global subjects modify their study strategy of the material on the generalization task. For the control group, global or analytical subjects have a different evolution for the performance and the strategic attitude according to the procedure. The analytical subjects are different from global subjects on the generalization task.  相似文献

以三类不同题目(与生活经验密切联系、与生活经验相悖、与生活经验“脱离”),探查了12岁普通儿童与数学成绩优异儿童充分条件假言推理能力发展的个体差异。通过对测查成绩的聚类分析,可将被试划分为四种不同的类型,从而显示出同一年龄儿童不同的推理能力发展水平:普通组儿童有关推理能力已有初步发展,但推理过程仍经常受其具体内容的束缚;数学成绩优异组儿童假设思维和演绎推理能力协调发展,“形式”从“内容”的束缚中解放出来,推理思维活动能较好地符合有关逻辑规则。这两组儿童假言推理能力的差异可能跟智能水平有关。  相似文献

The practical utility of cognitive self-instruction training in facilitating the work habits and academic performance of impulsive first-graders was assessed in the context of the regular classroom. The training paradigm was modified and environmental conditions were arranged to facilitate the transfer of the cognitive self-instruction strategy to the classroom. Following training, there were no significant increases in on-task behavior or in academic performance within the context of a group design. On the basis of this and other studies, a drastic revision of the cognitive self-instruction paradigm seems indicated. Not only must training become broader based, but models must be developed that take into account the requisite cognitive processes for task completion as well as the cognitive abilities of the youngsters to whom training is addressed. In general, the incorporation of information from the developmental and cognitive process literature would appear to facilitate the development of more effective training models.  相似文献

Working memory training has been shown to improve performance on untrained working memory tasks in typically developing children, at least when compared to non‐adaptive training; however, there is little evidence that it improves academic outcomes. The lack of transfer to academic outcomes may be because children are only learning skills and strategies in a very narrow context, which they are unable to apply to other tasks. Metacognitive strategy interventions, which promote metacognitive awareness and teach children general strategies that can be used on a variety of tasks, may be a crucial missing link in this regard. In this double‐blind randomized controlled trial, 95 typically developing children aged 9–14 years were allocated to three cognitive training programmes that were conducted daily after‐school. One group received Cogmed working memory training, another group received concurrent Cogmed and metacognitive strategy training, and the control group received adaptive visual search training, which better controls for expectancy and motivation than non‐adaptive training. Children were assessed on four working memory tasks, reading comprehension, and mathematical reasoning before, immediately after, and 3 months after training. Working memory training improved working memory and mathematical reasoning relative to the control group. The improvements in working memory were maintained 3 months later, and these were significantly greater for the group that received metacognitive strategy training, compared to working memory training alone. Working memory training is a potentially effective educational intervention when provided in addition to school; however, future research will need to investigate ways to maintain academic improvements long term and to optimize metacognitive strategy training to promote far‐transfer.

The purpose of this study was to develop a self-instructional package that would aid highly distractible retarded children in increasing their attending behavior in a training and two generalization (a one-to-one and a classroom) situations. Three untrained subjects were monitored for general comparison and social validation purposes. One of these control subjects was distractible and the other two (criterion comparison) were evaluated as not having attentional problems. A multiple baseline design was employed in which training was sequentially introduced across subjects. During training, the experimental subjects were taught through self-instruction to focus their attention and to cope with two tasks, math and printing. After learning the self-instructions the subjects were systematically and sequentially exposed to photo-slides of distracting situations, to audio-distractors composed of noisy lunchroom verbal peer interactions, and to in vivo distractors provided by kindergarten children playing with wooden blocks in the training setting. The entire training procedure was handled in a game-like context to maintain subject interest and to facilitate generalization. The results suggested that the training package produced direct and generalized changes in self-instructional behavior. In addition, a decrease in off-task behavior occurred during math, printing, and also during a phonics program in the one-to-one and classroom situations. However, reliable changes in academic task performance were not observed. Finally, no systematic changes on any of the dependent measures occurred for the three untrained subjects.  相似文献

Findings concerning the relation between dyslexia and speech perception deficits are inconsistent in the literature. This study examined the relation in Chinese children using a more homogeneous sample—children with phonological dyslexia. Two experimental tasks were administered to a group of Chinese children with phonological dyslexia, a group of age-matched control children, and a group of adults. In addition to a categorical perception task, a selective adaptation task was carried out. The results indicated that Chinese children with phonological dyslexia were less consistent than both the child and adult control groups in identifying stimuli within a given phonetic category. Furthermore, they did not show any significant adaptation effects in the selective adaptation task even when the adapting stimulus was identical to an endpoint stimulus in the test continuum. It seems that children with phonological dyslexia have a general deficiency in representing and processing speech stimuli.  相似文献

Preschool children in day schools were given instructions to complete certain tasks. Four tasks were given of two types and two levels of difficulty. In each condition compliance with at most one instruction (one task) was reinforced. In two similar experiments, with six children, general results were: compliance with easy tasks was maintained without reinforcement when any task compliance was reinforced; compliance for hard tasks remained high only when that specific task was reinforced. Thus, generalization of compliance with instructions varied with task difficulty. The setting and procedure for both studies were designed to reduce possible coercive features of laboratory studies of generalized performance. Results show generalized performance can occur under naturalistic conditions. The effect of effort, as a response characteristic affecting generalized performance, is discussed.  相似文献
