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

The number of facts college students correctly recalled was not affected by whether they were provided goals which did or did not encourage them to reorganize the passage material they studied. This held both for learners asked to recall all facts they could and those asked to recall only a portion of the goal-targeted facts. Learners whose recall exhibited reorganization of passage material did not differ in number of correctly recalled facts from those who failed to reorganize the passage material. Learners were more apt to reorganize the text materials when asked to recall only a portion of the goal-targeted facts than when asked to recall all facts they could. Self-report data suggest learners primarily use goals to rehearse the targeted material only after they carefully read a study passage.  相似文献

Children's incidental recall of pictures was examined in two related experiments. Extrapolating from adult research, it was predicted that categorizing pictures with respect to their semantic properties would yield greater recall than categorizing them according to their physical properties. In Experiment 1, second-grade children were exposed to 16 line drawings cross-classified to represent four taxonomic categories and four shape categories, with four instances per category. Control subjects simply looked at pictures. Semantic subjects identified each picture's semantic category, and Physical subjects identified each physical category. In Experiment 2, first graders freely sorted the pictures and were classified as Semantic or Physical sorters based on their predominant bases for sorting. Following exposure (Experiment 1) or sorting (Experiment 2), all subjects were asked to recall the picture names. Results of both experiments show that semantic classification yields greater recall than physical classification. Experiment 2 also shows that semantic sorting yields greater semantic clustering in recall and that sorting by physical category yields greater physical clustering. It was suggested that children's preferences for a mode of processing (Experiment 2) may constitute an individual difference dimension with fairly clear-cut instructional implications.  相似文献

Two experiments examined the effects of shifts in the modality on proactive interference in long-term memory. In Experiment 1 subjects learned a 40-word list presented in one of two forms of auditory/visual change—blocked or random. In the blocked conditions, learners were presented half the words in one modality followed by the remaining 20 words in the other modality. Subjects in random conditions also received 20 nouns in each modality, but the presentation was random. Following a delay, all subjects completed an 80-item recognition test. Analysis of these data showed a definite effect (p < .001) for the random change in modality when compared to the blocked presentation. As predicted, distinct reduction in serial position effects was found with the modality of presentation was random. In contrast, the blocked presentation produced two well-defined serial position curves. In Experiment 2 the effects of a shift in the modality of presentation on proactive interference were studied with high and low conceptual rigid subjects. Four similar prose passages were presented with a modality shift taking place in the last passage in a shift condition. Subjects in nonshift conditions were presented the passages exclusively in either the auditory or visual mode. The results showed that a shift in the modality of presentation of a prose passage provided a powerful releaser from proactive interference. The superior performance of rigid thinkers regardless of experimental group membership was explained in terms of organizational memory strategies.  相似文献

The degree to which the concreteness of prose material presented in an auditory fashion would interact with learners' lateral preference under different right hemispheric presentation conditions was investigated with 96 normal adults. Forty-eight subjects with consistent right preference patterns and a like number of bilateral individuals were either instructed to image, given a visual-spatial interference task, or given no instructions before listening to passages which differed in abstractness. As predicted across conditions, learners recalled a significantly greater number of ideas when the passage was concrete. Importantly, the abstractness was found to interact with subjects' inferred cerebral dominance. Whereas instructions to image and visual interference had little significant effect on mixed dominant subjects, for more consistently lateralized subjects imagery instructions increased and right-hemispheric interference decreased concrete recall. The results were interpreted in terms of visual and verbal encoding concomitant with cerebral lateralization.  相似文献

Ninety undergraduates of high and low prior knowledge of geology read a difficult prose passage concerning the formation of a meander. Two groups of learners were forced to process a map-like organizer either before or after they read the passage, while a control group was provided no pictorial support. The results showed that subjects with little prior knowledge who were provided with the organizer prior to reading recalled at a level similar to that of subjects with a good deal of background knowledge. The findings were interpreted as support for the use of map-like organizers in the primary position to aid comprehension.  相似文献

Two experiments examined the relative effects of questions requiring decisions, statements providing the decision information to students, questions not requiring decisions, and control procedures on students' memory for chemistry text reading materials. Experiment 1 employed immediate recall. The results of Experiment 1 indicated that students who made and justified decisions about the contents recalled significantly more information than students in any other condition. In addition, students who answered questions that did not require decisions recalled significantly more of the content than students in the control or the statements conditions. No other contrasts reached significance. Experiment 2 employed delayed recall assessed one week after reading. The results confirmed those of Experiment 1. The overall results of the study are discussed in terms of an elaboration perspective on memory.  相似文献

The effect of lateral preference on passage comprehension and short-term memory function was examined for 48 normal fourth-grade males. Scores on a self-report measure of lateral preference were used to divide the children into groups who differed in their laterality. The subjects were tested for basic comprehension on written and aurally presented prose in standard and nonstandard phrase form. Consistently lateralized readers recalled more information under the auditory than under the written conditions, while bilateral readers showed no preference for mode of presentation. Between-group comparisons showed bilateral readers to comprehend significantly more in the written conditions than did the other group. Groups did not differ on recall of auditorily presented material or on short-term digit memory. These results may be interpreted as demonstrating that bilateral preference need not be tied to reading difficulty.  相似文献

In this study, high school students were trained to use adjunct maps strategically while studying a History text. Subjects were randomly assigned to either a control or map training group which read a lengthy passage which was accompanied by three maps. The control group was instructed to study the materials and write an essay about them. The map training group was instructed to study the materials and to place important event information from the text on their maps; they also discussed how their maps could be used to help them remember the text. One week later multiple choice, probed recall, free recall, and map recall tests were administered. Three weeks after training both groups read a transfer text and were instructed to use the attached map to help them remember the information. Free recalls were gathered after a short delay. Results showed that map training subjects obtained higher scores on all of the training text recall measures and on the main idea level transfer text measures. High ability map training subjects also recalled more details. Maps used in the transfer task showed trained subjects using the strategies they had been taught.  相似文献

We used an immediate recall paradigm to study the effects of list organization and semantic and grammatical features of printed stimuli on working memory capacity in deaf students with differing English language abilities. Thirty lists of five organizational types (random words, semantically related words, semantically paired words, scrambled sentences, and grammatical sentences) were presented to two groups of deaf students who differed in their proficiency in the English language. The students were required to recall the lists in writing. The results indicate that, overall, the students with higher levels of English language proficiency recalled significantly more than those with lower levels. Additionally, semantic and syntactic organization of the lists had different effects on the two groups of students. Semantic pairing aided the low-level group significantly more than the high-level group, whereas the syntactic organization of the grammatical sentences aided the high-level group significantly more. Implications for assessing language ability in deaf students are discussed.  相似文献

Previous research has established that the degree of ‘wordlikeness’ of nonwords affects young children's nonword repetition performance. Experiment 1 examined the possibility that output processes are responsible for the wordlikeness effect by using a probed recall procedure. Wordlikeness was defined in terms of phonological neighbourhood density, although this measure was found to be related to the traditional measure of wordlikeness involving adult ratings. A significant effect of number of phonological neighbours/wordlikeness was observed in favour of nonwords with many neighbours. In Experiments 2 and 3 the wordlikeness effect was qualified by a significant interaction with nonword repetition ability. Children with poorer repetition ability were affected by number of neighbours/wordlikeness, while children with better repetition ability were not. Children with poorer repetition ability were significantly poorer than the better repeaters with nonwords with few neighbours. The results were interpreted in terms of theories of phonological development that suggest progressive segmentation of lexical representations. In Experiment 4 the relationship of children's nonword repetition ability to phonemic discrimination ability was investigated. The results demonstrated that children with better nonword repetition ability had superior phonemic discrimination performance than children with poorer nonword repetition ability.  相似文献

This study examined the effects of pictorial advance organizers, provided prior to reading a passage, on students' retention of passage information. Fifth-graders studied a passage for 8 min and were asked to recall the material immediately and 1 week later. Prior to studying the passage some subjects were given 2 min to study an integrated pictorial advance organizer, a fragmented pictorial advance organizer, the passage, or nothing. Students given the integrated pictorial advance organizer recalled more than the other groups on both immediate and delayed tests of recall. These results extend previous research on verbal advance organizers by indicating that pictorial advance organizers can serve an organizing context for incoming passage information.  相似文献

This study makes use of the “levels effect” in prose recall to increase older adults' recall of important medical information. Seventy older adults (over 65) read and recalled two passages containing medical information about hypertension and arthritis. Half of the adults read the passages in which the text structure had been revised so that target ideas (identified as important by physician consultants) were located at the highest levels of the content structure. Recall of target ideas, details, and total number of ideas were investigated. Results showed an increase in recall of target ideas for the revised passages. Education, medical condition, and age also affected recall to differing degrees depending on the measure studied. The results indicate that older adults remain sensitive to differences in prose structure and that their memory for important information can be improved by use of principles developed with younger subject groups.  相似文献

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

There is now substantial evidence that pictures can be used to facilitate the recall of information presented in prose passages. There is also evidence that the presence of pictures in prose passages does not hinder the recall of information that is not pictured. Are the picture effects durable over longer periods (55 days) of time? Do pictures included in prose passages help or hinder subjects' recall of information that is not pictured? Results of this study provide evidence that picture effects are durable. In addition, the inclusion of pictures in prose passages did not interfere with the recall of information presenter' only in the prose passage.  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

The study reported investigated whether using both of a bilingual's languages to process expository text enhanced or impaired comprehension. Eighty French-English bilinguals read a passage written in either French or English, took notes on the passage in either French or English, and completed tests of free recall and inference in French and English. Bilinguals who used both of their languages to read and take notes neither recognized nor recalled more information overall than their counterparts who read and took notes in the same language. Bilinguals who read and took notes in alternate languages, however, recalled more of those notes than subjects who read and took notes in the same language. Implications for future research pertaining to the interaction of bilinguals' languages during processing of text are discussed.  相似文献

Witnesses?? event recall and the realism in their evaluation of the correctness of their recall are of great importance in forensic processes. These issues were investigated in the present study by use of calibration methodology. More specifically, we analyzed the effects of two recalls of the same event (repetition) and of probes (non-informative follow-up questions at recall) on 9?C11?year-old children??s and adults?? open free recall and the degree of realism in the participants?? confidence judgments of the correctness of the recall after they had seen a short video clip. The findings were that repetition resulted in more units recalled both for children and for adults, and in that the children showed higher overconfidence compared with one recall, but not the adults. Moreover, when only the statements in the repetition conditions that were recalled twice were included in the analysis, higher confidence was found for the children (independent of an increase in the proportion correct statements of all statements) but not for the adults. Probing increased the number of units recalled for both children and adults, decreased the children??s proportion correct statements but not the adults??, decreased both children??s and adults?? confidence and increased the children??s overconfidence, but not the adults??. Finally, the combination of two recalls and probing disrupted the children??s but not the adults?? metacognitive performance.  相似文献

The purpose of this study was to examine the effects of grade level and recall task type on children's memory for explicit, implicit and metaphorical information following reading. Forty second and 40 fifth grade subjects balanced as to gender read four prose passages and were randomly assigned to cued and free recall conditions. A MANOVA produced significant main effects for grade level and task type on each of three dependent variables; EXPLICIT, IMPLICIT and METAPHOR recall measures. As predicted, fifth graders fared better than second graders and the cued condition exceeded free recall. Of greater significance was the finding that second graders were able to engage in metaphorical reasoning when the task was appropriately structured. The results suggest that providing externally generated, structured probes can greatly enhance children's reading recall at both grade levels and can enable children to demonstrate metaphorical comprehension prior to the age at which it spontaneously appears. In addition, significantly different patterns of recalled information were found within the two task conditions, patterns that remained stable across age groups.  相似文献
