This research compared the performance of younger (mean age — 20.7 years) and older (mean age–68.3 years) adults on a memory task that involved pictures, words, and pictures‐plus‐words as stimuli. The results, consistent with previous research, indicated an equivalent picture superiority effect for both young and old adults when pictures were compared to words. More specifically, although recall scores were significantly higher for younger adults compared to older adults, the superior recall scores for pictures versus words did not differ between the age groups. However, the performance of older adults declined markedly, compared to the younger adults, in the picture‐plus‐word condition. These findings are interpreted as providing support for a divided attention model, which involves effortful processing of both visual and verbal aspects of stimuli. This situation of divided attention appears to put older adults at a relative disadvantage compared to young adults. 相似文献

3 studies examined the development of recognition memory for the left-right orientation of pictures of common objects. In study 1, 5-year-olds, 9-year-olds, and college students were shown 20 pictures of objects. Subsequently, they were tested on their ability to discriminate between 10 of these pictures and their left-right mirror images and between the other 10 pictures and completely new ones. There were large developmental differences in memory for orientation, although all age groups could discriminate accurately between familiar pictures and completely new ones. In studies 2a and 2b, training concerning the relevance of orientation improved second and fourth graders' long-term memory for this characteristic, but training effects were minimal for kindergartners. However, even kindergarten children showed accurate short-term memory for orientation on the task used for training. In contrast to study 2, study 3 produced accurate long-term memory for orientation in kindergarten children by using a verbal training procedure. Results are discussed in terms of the range of memory factors involved in children's mirror-image confusions and in terms of general implications for the development of recognition memory. 相似文献

When induction meets memory: evidence for gradual transition from similarity-based to category-based induction 总被引：3，自引：0，他引：3
The ability to perform induction appears early; however, underlying mechanisms remain unclear. Some argue that early induction is category based, whereas others suggest that early induction is similarity based. Category- and similarity-based induction should result in different memory traces and thus in different memory accuracy. Performing induction resulted in low memory accuracy in adults and 11-year-olds, whereas 5-, and 7-year-olds were highly accurate (Experiment 1). After training to perform category-based induction, 5- and 7-year-olds exhibited patterns of accuracy similar to those of adults (Experiment 2). Furthermore, 7-year-olds, but not 5-year-olds, retained this training over time (Experiment 3). With novel categories, even adults performed similarity-based induction, exhibiting high memory accuracy (Experiment 4). These results suggest a gradual transition from similarity- to category-based induction with familiar categories. 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

Episodic memory relies on discriminating among similar elements of episodes. Mnemonic discrimination is relatively poor at age 4, and then improves markedly. We investigated whether motivation to encode items with fine-grain resolution would change this picture of development, using an engaging computer-administered memory task in which a bird ate items that made her healthier (gain frame), sicker (loss frame), or led to no change (control condition). Using gain-loss framing led to enhanced mnemonic discrimination in 4- and 5-year-olds, but did not affect older children or adults. Despite this differential improvement, age-related differences persisted. An additional finding was that loss-framing led to greater mnemonic discrimination than gain-framing across age groups. Motivation only partially accounts for the improvement in mnemonic discrimination. 相似文献

Previous research demonstrates that patients typically have difficulty remembering information presented during healthcare consultations. This study examined how older adults learn and remember verbally presented medical information. Healthy older adults were tested for recall in experimental and field settings. Participants viewed a five-minute video of a simulated healthcare consultation and completed free recall, cued recall, and recognition memory tasks. Differences in performance were observed between older and younger adults in the experimental condition on all memory tasks and in the field condition on the cued recall task; older adults tended to remember less information than younger adults. Though older adults had difficulty spontaneously recalling medical information, they were able to take advantage of cues to access verbally learned information. Findings of this study highlight the importance of developing and implementing measures to maximize the abilities of older adults to learn and remember important medical information communicated by healthcare providers. 相似文献

The term ‘modality effect’ in multimedia learning means that students learn better from pictures combined with spoken rather than written text. The most prominent explanations refer to the split attention between visual text reading and picture observation which could affect transfer of information into working memory, maintenance of information in working memory or the effective size of working memory. The assumption of a continuous need for split attention is questionable, however. Learners can keep pictorial information in working memory, when they have seen the picture before, especially if they have higher prior knowledge. Instead of suffering from a permanent split attention, learners frequently show tendencies to simply ignore pictures. This suggests guiding learners towards picture analysis by picture-related text paragraphs. We assume that these paragraphs are associated with stronger modality effects than content-related paragraphs, especially if the pictures are new to learners. These assumptions were tested in an experiment with 120 students learning about volcanism from illustrated text consisting of segments each including a content-related paragraph followed by a picture-related paragraph describing the accompanying visualization. Content-related and picture-related paragraphs were presented as visual or auditory texts leading to 2x2 conditions of text presentation. Picture novelty was manipulated by presenting a picture throughout the whole segment or only when the picture-related paragraph was read. As expected, picture-related paragraphs were associated with stronger modality effects than content-related paragraphs if picture novelty is high. The distinction between different kinds of paragraphs seems to be important for the prediction of modality effects. 相似文献

Summary The present study investigated the relationships of meaningfulness, picture detail, and presentation mode on visual learning.
Subjects, 123 broadcasting students at Brooklyn College, viewed slides of animal pictures previously classified by judges
into high-and low-meaningful groups. All Ss saw both high-and low-meaningful stimulus items. Half saw the stimulus items as
full-color pictures while the other half saw them as line drawings. In addition, one-third saw the stimulus items as pictures
presented alone, one-third saw them as pictures with each animal name printed underneath its picture, and one-third saw the
pictures (without printed names) accompanied by the spoken animal name as each slide was shown. Following presentation of
stimulus slides, Ss were shown a series of full-color test slides containing dummy items randomly intermixed with stimulus
items. During two showings of test slides, Ss first indicated those animals recognized from the learning trial and second,
wrote down those animal names they knew.
Results included significant main effects on recognition accuracy for meaningfulness and presentation mode in addition to
significant interactions for meaningfulness-by-mode and mode-by-picture-detail. A significant main effect of presentation
mode resulted for correctly named stimulus items. Three significant main effects (meaningfulness, picture detail, and mode)
and one significant interaction (mean-ingfulness-by-picture-detail) were obtained on error scores. 相似文献

We conducted a survey to compare a group of older adults’ and a group of younger adults’ beliefs regarding their own and each other's memory abilities. We also asked both age groups to identify items they believed older adults remember well. The survey was returned by 185 older (ages 60‐92) and 184 younger (ages 17‐39) participants. Of the 30 items we generated older adults reported that they would remember 23 better than younger adults would and 7 worse than younger adults would, and younger adults reported that they would remember 12 of the items better and 18 of them worse than older adults. Both age groups also generated many items that they believed older adults remember better than younger adults do. Finally, respondents generated items that they believed adults in their own age group had to remember routinely that adults in the other age group did not. The two groups agreed that older adults would spend more time and have more difficulty learning lines for presentation to an audience than would younger adults. Most of the older adults reported that their memories had changed; most of the younger adults reported that their memories had not changed. The belief that although older adults’ memory is worse than young adults’ they still remember some things better than the young is viewed as a realistic assessment, and implications for future research are discussed. 相似文献

Reaction times and picture evaluations by 18 adults with hearing loss were compared with those of 18 matched controls during two visual priming tasks. In Task 1, participants reacted to sexual and plant target pictures (while influenced by similar preceding pictures) by pressing "sex" or "plant" buttons. In Task 2, they evaluated target Japanese ideographs (while influenced by preceding positive or negative facial expressions as prime pictures) by pressing "positive" or "negative" buttons. In Task 1, the controls had the faster responses. In Task 2, they showed the usual congruent priming effect during very short prime presentations. Participants with hearing loss showed this effect only during short and long prime presentation times; thus, they were not superior to the controls in picture recognition, instead showing (a) impaired processing of visual information or (b) impaired perceptual-motor skills regarding quick responses to visual information (or both). 相似文献

Previous research has shown that pictures can be effective in enhancing text memory. For example, Waddill and McDaniel (1992) found that pictures depicting detail information in an expository text effectively enhanced recall of those details and pictures depicting relational information effectively enhanced recall of those relations. However, the research on picture enhancement effects raises the question of whether the mnemonic value of pictures is simply a by‐product of having drawn attention to parts of the text through selective repetition of text content. The present study addressed the question by comparing the relative effectiveness of pictures versus simple verbal captions in promoting text memory. The results replicated the Waddill and McDaniel (1992) pictorial enhancement effect. However, the results showed that repeating the targeted information in a verbal caption was as effective as providing a pictorial illustration, thus suggesting that repetition of text content rather than nonverbal pictorial illustrations produced the effect. The findings generalized across three texts that differed in the amount of spatial content they conveyed. 相似文献

The effects of different modes of verbalization on recognition memory of object detail were examined in first- and third-grade children and adults. The results indicated that both age of the subject and the type of verbalization used during initial picture viewing influenced recognition accuracy for object detail. When compared to nonverbal viewing groups, only specific types of verbalization increased recognition accuracy for third-grade and adult subjects. None of the modes of verbalization was effective in increasing first-grade recognition scores. The results indicate that general statements concerning the facilitating or inhibiting influence of verbalization on recognition memory must be qualified. In addition, the results showed that developmental differences in recognition accuracy are contingent upon the type of strategy used during the encoding process. 相似文献

Monolingual, native French-speaking subjects (9- and 11-year-old children and adults) were requested either to talk or write about nine triplets of pictures whose components varied along the pragmatic dimension «new vs. given information». In the first picture in each series, all components were new. In the second and third pictures, one component was replaced each time by a new component, the other components becoming given. The oral execution of the task made the experimenter (the addressee) into a co-producer of the situational discourse produced, whereas the written production situation placed a certain distance between the producer and the addressee. The expression of the contrast between old versus new elements to be described in each situation was studied by examining the use ofarticles (definite andindefinite) andpronouns. The expression of oldness and newness by means of articles was more common in speaking than in writing. In the oral medium, the given/new contrast was marked more and more often as age increased, although this was not true in the writing situation, where the subjects generally used definite articles, even when referring to a new element. Pronouns were used infrequently orally, particularly by 9-year-olds, to express the increasing «oldness» of the elements. The written use of pronouns was extremely rare. Although it was already present orally in older subjects, the tendency to give autonomy to the production associated with each picture (decreasing use of pronouns in favor of nouns) was predominant in the written medium. Maximum explicitness was favored in writing (due to the deferred reception of the production by the addressee), and the marking of elements as new or given was therefore not given priority. The way in which the written and oral production media modulated the choices of the subjects is discussed. 相似文献

Objective and subjective indices of imagery and verbal ability and their relationship to recognition memory for pictures and concrete words were examined in a large correlational study. Objective spatial tests of imagery proved to be better predictors of picture recognition than were self‐assessments, the Flags test excepted. Spatial tests also predicted word memory in males, but not females. Imagery control and imagery vividness bore little relation to recognition; vividness within specific modalities may have some influence, however, particularly in males. Verbal fluency and verbal comprehension were either unrelated or marginally negatively related to performance. In general, a more specialised pattern of ability‐performance correlations emerged for females than for males. 相似文献

This research explored the development of one insight about the mind, namely, the belief that people's trains of thought differ even when they see the same stimulus. In Study 1, 5-year-olds, 9-year-olds, and adults heard stories about characters who saw the same object. Although the older groups predicted the object would trigger different trains of thought, most 5-year-olds did not. In Study 2, 5-year-olds (preschoolers and kindergartners) and 7-year-olds heard similar stories, plus stories with additional individuating information about each character. With age, children increasingly recognized that thoughts would differ and could explain why. The development of this insight during the school years likely provides children with a more complete understanding of what it means to be a unique individual. 相似文献

Previous research on adults' and children's memory for the time of past events has generally overlooked the fundamental distinction between knowledge of temporal distance in the past and knowledge of temporal locations. This study applied the distinction to the development of time memory. Children of 4, 6, and 8 years of age experienced 2 target events, one 7 weeks and the other 1 week before testing. They were asked to judge the relative recency of the 2 events and to localize the older event by time of day, day of the week, month, and season. Even the 4-year-olds were successful in judging the relative recency of the 2 events and localizing the older event by time of day. However, on the 3 longer time scales, only the 6- and 8-year-olds could localize the older event, reason about possible times that it could have occurred, or tell the present time. The great accuracy of the time-of-day judgments at all 3 ages is almost certainly not due to distance-type information. The results show the separate development of distance and location judgments. 相似文献

A tale of two representations: the misinformation effect and children's developing theory of mind 总被引：1，自引：0，他引：1
The present research investigates representational ability as a cognitive factor underlying the suggestibility of children's eyewitness memory. The misinformation effect is used as an index of children's suggestibility, and performance on the false belief task is used as an assessment of children's representational abilities (N = 117). Analyses that considered the effect of representational ability and general memory ability on children's susceptibility to misleading information showed that differences in representational ability and general memory ability predicted participants' susceptibility to misleading information. These results demonstrate that the eyewitness memory of children who lack either multirepresentational abilities, sufficient general memory abilities, or both (i.e., most 3- and 4-year-olds) is less accurate than the eyewitness memory of children with both multirepresentational abilities and sufficient memory abilities (i.e., most 6-year-olds and adults). Thus, it appears that the earliest age at which children's eyewitness memory can be considered to be similar to that of adults is 6 years of age, when children's mental representational abilities are similar to those of adults. These results suggest that one factor underlying children's vulnerability to misleading information is the number of representations of an event that they can simultaneously hold and compare. 相似文献
