The effects of a prose passage's physical structure and semantic organization upon free recall performance was investigated. Passages, describing characteristics of fictitious countries, contained either five or nine paragraphs on attributes of the countries. Results showed that Mandler's in J. L. Cowan (Ed.), Studies in thought and language. Tucson: University of Arizona Press, 1970] organizational limits could apply to prose as well as word lists and could be used to explain previous discrepant results in semantic organization research. Results showed differences in the distribution of materials interacting with type of semantic organization to produce differences in recall. Different learning strategies imposed by the passage's semantic organization were also found. 相似文献

In recent research on memory for prose, attention has focused on the influence of a reader's perspective or schema on what is encoded and subsequently recalled. Previous research has revealed that subjects were able to recall previously unrecalled information if they were directed to take a new perspective during a second recall trial. This has been termed the perspective shift effect. This paper describes two possible mechanisms to account for the perspective shift effect—a retrieval process and a decision process. Two experiments which investigated the roles of these processes in the perspective shift effect are described. Experiment 1 employed an incentive to influence the subjects' criterion for reporting recalled information. Experiment 2 obtained separate estimates for decision and memory processes by applying signal detection theory. The results of both experiments provide data that tend to rule out the decision process as an important factor in the perspective shift phenomena in recall. 相似文献

两个实验采用联结学习范式,分别探讨知觉类别和语义类别材料中,类别感知对特征学习的影响.结果发现,即使是在联结学习范式中,当学习者感知学习材料存在类别时,不仅关注可以有效预测结果的特征,也会关注类别中的其他特征.同时,在知觉类别和语义类别材科中都发现了相同的结果.本实验结果说明,当学习者感知学习材料中存在类别时,即使是在联结学习范式中,学习者也会像类别学习范式中一样,学习额外特征,支持对存在类别的感知,是影响学习者特征学习的重要原因. 相似文献

Second graders, fifth graders, and adults participated in 2 experiments designed to study the effects of sorting on subsequent recall of unrelated words. 1 group sorted the items freely, while a second group was constrained to learn the sorting schemes generated by free subjects. In the first experiment, subjects sorted until they reached a criterion of organizational stability. In Experiment 2, sorting was terminated prior to reaching a stable criterion. Recall and output clustering were reduced in Experiment 2, relative to Experiment 1, because of organizational instability. No meaningful differences were found in either experiment in the sorting schemes generated by free subjects in the 3 age groups, nor was there an effect of age of yoking partner on performance of constrained subjects. This result differed from previous research, and it was concluded that the sorting technique diminished differences in organizational behavior usually found between older and younger subjects. 相似文献

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. 相似文献

This experiment studied the relationships among cheating, overall test performance, and the relatedness of materials available and unavailable to the cheater. Subjects learned a free-recall list and were then tested for recall either when cheating was impossible or when half of the list had been left “carelessly” exposed. For half of the cheat subjects the exposed and the unexposed words belonged to different categories, while for the remaining halves the items belonged to the same categories. Recall was scored for both exposed and unexposed words. The results indicate that significant cheating did occur, that cheating did not improve overall performance, and that while cheating elevated the numbers of recorded exposed words it depressed recall of stored unexposed items (for both related and unrelated sets). This associated cost effect is discussed in connection with category retrieval, output interference, attention, and arousal. 相似文献

Previous research has indicated that the keyword method of vocabulary learning facilitates students' performance not just on simple tests of definition recall, but on comprehension-demanding tasks as well. The present study was conducted to determine whether the “comprehension” finding could be accounted for by keyword subjects' superior definition recall per se. The results generally supported that conclusion: When conditions and subjects within conditions were equated with respect to their initial levels of definition recall, the comprehension advantage of keyword subjects disappeared. 相似文献

Abstract In 2000–2001, the authors derived a 13-category classification system for Web-based educational resources, based on analysis of 199 educational resources recognized as “exemplary” by four national entities. In 2004, we re-examined that classification system, analyzing a stratified random sample of 40 exemplary Web-based resources from the same entities. While the classification system still accommodated categorizing current educational resources, we detected some overlap among categories. Through combination and redefinition, we reduced the number of categories to eleven. This article addresses the initial and modified classification systems, the analysis procedures employed, examples of resources in each category, and future applications of the classification system. 相似文献

In two experiments, subjects read prose materials with various organizations of the superordinate and subordinate conceptual structure of the passage. Variables included organizational salience, massed versus distributed repetition of the passage, nature of the cueing at recall, and number of exposures. In Experiment I, distributed repetition resulted in superior recall, extending the generality of that effect to prose materials; and an advance organizer treatment resulted in lower recall for scrambled materials, contrary to Ausubel's (1960) cognitive theory. High ability subjects recalled more categories than low ability subjects, but the same amount of within-category information. In Experiment II, materials which increased the salience of the organizational structure of the passage were better recalled than scrambled materials after three exposures, or on a test which cued the major categories in the passage. Cueing was detrimental to performance for subjects reading the scrambled passage. Results are discussed in terms of implications for educational practice. 相似文献

Children's Memory for Traumatic Injury 总被引：3，自引：0，他引：3
Children between 2 and 13 years who suffered traumatic injury necessitating hospital emergency room treatment were recruited as subjects. They (and adult witnesses) were interviewed a few days and 6 months later, using free and probed recall, about both injury and hospital treatment. Children at all ages were able to provide considerable information about both stressful events, although the amount of detail increased with age. They also made few commission errors. Surprisingly, children's distress at time of injury did not affect the amount or accuracy of their recall of that event, whereas distress during hospital treatment did decrease recall. A tripartite classification into 3 categories of detail was used: central, peripheral-inside the emotional events, or peripheral-outside those events. Children's recall differed depending upon detail category. Implications for children's testimony are discussed. 相似文献

The effects of semantic and phonetic radicals on Chinese character decoding were examined. Our results suggest that semantic
and phonetic radicals are each available for access when a corresponding task emphasizes one or the other kind of radical.
But in a more neutral lexical recognition task, the semantic radical is more informative. Semantic radicals that correctly
pertain to character meaning facilitated reaction time in semantic categorization tasks (Experiment #1), while radicals that
had no immediately interpretable relation to character meaning had a strong inhibitory effect. Likewise, phonetic radicals
that accurately indicated a character’s pronunciation facilitated a homonym recognition task (Experiment #2), whereas phonetic
radicals that differed significantly in pronunciation from their character inhibited homonym recognition. In a lexical decision
task (Experiment #3) where each character had either a blurred semantic radical or a blurred phonetic radical, the characters
with a blurred semantic radical elicited a significantly higher error rate and a trend for longer response times. These results
are interpreted to indicate that while educated native Chinese speakers have full use of both semantic and phonetic paths
to character decoding, there is a slight predisposition to semantic decoding strategies over phonetic ones indicating that
the semantic path is the default means of character recognition. 相似文献

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. 相似文献

Kagan's Matching Familiar Figures Test was used to select 36 impulsive and 36 reflective children at each of three grade levels: kindergarten, second, and fifth. An incidental learning paradigm was used to assess the child's recall of central and incidental information. Reflective subjects recalled more central and incidental information than impulsives, suggesting that impulsives have difficulty encoding information for storage. Central recall increased with grade level but incidental learning remained constant, a finding consistent with the developmental trend found in previous investigations. A task order effect was found in the recall of central information with more errors made when the central recall task was presented after the incidental. This order effect may account for the higher central recall scores found in previous investigations. Other problems with the incidental learning paradigms raise questions about the validity of the task for inferring selective attention. Despite the problems associated with the task, the results offer further evidence to support the notion that impulsive and reflective children differ on dimensions other than response latency. 相似文献

Children's understanding of the static representation of speed of locomotion was explored in 2 experiments. In Experiment 1, 20 7-year-olds and 20 9-year-olds drew pictures of 2 people walking and running at different speeds. Children then made judgments about pairs of unambiguous drawings of a person walking or running, as did a sample of 20 adults. The drawings varied according to whether action lines, background lines, or no lines were present. Children were asked to say which figure appeared to be moving faster. In Experiment 2, 20 7-year-olds, 20 9-year-olds, and 21 adults sorted ambiguous drawings of a person walking and running at different speeds. The pictures again contained action lines, background lines, or no lines. In the drawing task, children more frequently used page position and biomechanical information than action lines to represent fast and slow walking and running. In the judgment task, 7- and 9-year-olds offered equivalent judgments of action lines and background lines, whereas adults distinguished between these pictorial devices. In the sorting task, all subjects distinguished between action lines and background lines and judged that pictures containing action lines looked faster than pictures containing background lines and pictures without lines. Taken together, the results indicate that subjects' judgments were influenced by the form of locomotion and degree of ambiguity in the depicted events they saw. The findings are consistent with the view that different categories of pictorial devices exist, but the effectiveness of each device is contingent upon the perceiver's experience with it and the context in which it appears. 相似文献

Younger children’s free recall from episodic memory is typically less organized than recall by older children. To investigate if and how repeated learning opportunities help children use organizational strategies that improve recall, the authors analyzed category clustering across four study-test cycles. Seven-year-olds, 10-year-olds, and young adults (N = 150) studied categorically related words for a free-recall task. The cognitive processes underlying recall and clustering were measured with a multinomial model. The modeling revealed that developmental differences emerged particularly in the rate of learning to encode words as categorical clusters. The learning curves showed a common pattern across age groups, indicating developmental invariance. Memory for individual items also contributed to developmental differences and was the only factor driving 7-year-olds’ moderate improvements in recall. 相似文献

The study was designed to assess the effects of a student's race, dialect, and physical attractiveness on teachers' evaluations. The students were of two races, black and white; three physical attractivenss levels, high, middle, and low; and they spoke one of two dialects, Black English or Standard English. Sixty-eight, white, elementary school teachers listened to each student's response and rated the student in terms of personality, quality of response, and current and future academic abilities. Analysis of the results showed that all main effects and interactions were significant. Generally, black students, Black English-speaking students, and low attractive students were rated lower. The results also revealed that teachers' ratings in the different areas were highly consistent with one another. Discussion centered around the results' implications for determining the cause(s) of black children's failure in school. The results provide some support for attributing these children's academic failures to their race and dialect rather than to their actual performance. 相似文献
