The application and transfer of free recall study strategies were examined for young, middle-aged, and elderly adults. Subjects were either instructed to use clustering and imagery, instructed to use their own study strategies, or given standard free recall instructions. Subjects at all age levels showed high initial use of categorization and low initial use of imagery. Subject-reported imagery increased after training, but categorization was the only strategy associated with higher recall levels. Training produced increases in recall clustering that were apparent only on a transfer list. The results provided evidence that adult age differences in memory occur even when middle-aged and elderly adults show evidence of categorization in recall.  相似文献

The "appropriate" age for retirement as it is perceived by young adults, middle-aged adults, and elderly people has been studied. No respondents were surprised or had trouble expressing an opinion about the minimum and maximum "appropriate" ages for retirement. Representations of the "appropriate" retirement age vary primarily as a function of the perceived physical constraints involved in the occupation, and also depend on the age of the person being questioned; the younger the respondent, and lower the perceived "appropriate" minimum age. There was no tendency among the young adults to prolong the work life of older individuals. Nor was there a tendency to associate aging with the loss of intellectual capacities likely to lead to early retirement.  相似文献

Abstract

Young and elderly adults heard recorded passages of meaningful prose with instructions to interrupt the speech at points of their choosing for immediate recall on a segment by segment basis. At normal speech rates both young and elderly subjects segmented passages primarily at coherent syntactic boundaries and showed equivalent recall performance. Increasing the passages' speech rate produced a significant reduction in recall performance for the elderly subjects relative to the young even though their segmentation strategies remained the same. Results were attributed to an age-sensitive encoding difficulty at a level higher than surface syntactic parsing.  相似文献

Younger adults (mean age = 19.6), 73-year-olds and 82-year-olds were examined on free recall of verbal materials varying in datedness (i.e., names of people who attained their fame during the 1930s or the 1980s). The main result was an interaction between age and type of materials. Whereas younger adults performed better for "new" than for "old" items, both elderly groups recalled more old than new items. A highlight of these data is that activation of pre-experimental knowledge structures appears to improve episodic recall in both young-old and old-old adults.  相似文献

Adolescents, middle-aged, and elderly adults used a Likert scale to describe an ideal, real, or typical person of either their own age group or one of the other two. On each of four dimensions of instrumentality, autonomy, acceptability, and integrity, ideal people were characterized more positively than real or typical ones. Age of neither participant or stimulus object affected these judgments. Stereotypes emerged when typical people were rated, though judgments on real people suggested little difference between elderly and middle-aged people. However, real adolescents were judged to be more unacceptable, dependent, and instrumental than were middle-aged and elderly adults. On instrumentality the age groups differed in their perceptions of each other. Adolescents and middle-aged adults perceived instrumentality to decline in old age, but the elderly did not agree. Thus attitudes reflected stereotypes when broad categorical decisions were required, but stereotypes broke down when known people were characterized.  相似文献

This study was designed to examine effects of differences in age, health, education, and sex on state and trait anxiety, and to assess interrelations between anxiety and performance on reasoning and problem solving tests. A significant main effect of health status was obtained for trait anxiety, but age, education, and sex effects were nonsignificant for both anxiety variables. Anxiety ratings were inversely correlated with performance on tests of reasoning and problem solving (traditional and practical Piagetian tasks, matrices, and similarities), but the pattern of intercorrelations was stronger within the middle-aged (40-59 years) as opposed to the elderly (60-79 years) groups. The findings fail to support the hypothesis that anxiety increases with age, or that the elderly are disproportionately affected by anxiety in testing situations.  相似文献

This report describes sentence-final word completion norms for 119 sentence contexts based on the original sentence completion norms of Bloom and Fischler (1980). Four sets of norms are made available for 358 adults, representing young, middle-aged, young-old, and old-old samples. Notable in these norms is a high degree of consistency in responses among all four age samples. Differences in relation to the original Bloom and Fischler norms appear in responses to low contextually constraining sentences. Results show that the recency with which normative data are collected is an important variable to consider when making use of norms.  相似文献

Names from one of four list conditions (elderly-relevant, young-relevant, nonmeaningful) were presented to 56 young and 56 old adults. Contrary to the findings often reported in the gerontological literature on memory, with free recall the elderly adults remembered as many names as did the young. Superior performance for the young was observed only in the young-relevant list condition. The elderly adults recalled significantly more names than did the young from the elderly- and both-relevant lists. No differences were observed for the nonmeaningful list. When asked to rate their perceived performance on the memory task, however, the older adults rated themselves lower than the young adults.  相似文献

We examined whether the relationship between control beliefs and memory performance varied for young, middle-aged, and older adults and whether strategy use mediated this relationship. Participants were 335 adults, ages 21 to 83, who had been recruited from local probability samples. We used structural equation modeling to test the predicted model and compare it by age group (young, middle-aged, and older adults). As expected, control beliefs were related to memory performance on a word list recall task for middle-aged and older adults, but not for younger adults. An analysis of indirect effects revealed that strategy use partially mediated this relationship. Specifically, middle-aged and older adults who perceived greater control over cognitive functioning were more likely to categorize the words and had better recall performance.  相似文献

Three experiments investigated spatial perspective-taking ability in young and elderly women. The three experiments differed with regard to the method by which subjects were initially familiarzied with the experimental stimuli. Subjects were required to make decisions about the correctness of each of several types of slides presented to them. The amount of time required by subjects to make their responses was also obtained. The results show a smaller age difference in accuracy of performance when individual components of the stimulus array were examined in isolation (Experiment 2) than when the array was actually previewed from the perspective-taking positions (Experiment 1). Furthermore, a combination of the two methods of familiarization (Experiment 3) did not reduce the age difference in accuracy of performance beyond that obtained by the examination of individual components alone. Age differences in reaction time for correct responses, however, steadily decreased between Experiments 1, 2, and 3. These results raise the possibility that cognitive systems associated with storing and retrieving spatial information may decline more rapidly across the adult life span than cognitive systems involved in the construction of unviewed spatial information.  相似文献

Test anxiety in elderly and young adult college students was measured by the Anxiety Achievement Test following a free-recall memory experiment. As expected, the elderly had higher levels of debilitating test anxiety than the younger adults. A large proportion of older persons showed behavioural manifestations of test anxiety either by refusing to participate in the study, or by their reactions during the testing. Test anxiety was related to memory performance among both age groups, suggesting than an older person's performance on a cognitive task may be influenced by affective reactions to the testing situation itself.  相似文献

Human metapneumovirus infections in young and elderly adults   总被引:31,自引:0,他引:31  
Human metapneumovirus virus (hMPV) is a newly discovered respiratory pathogen with limited epidemiological data available. Cohorts of young and older adults were prospectively evaluated for hMPV infection during 2 winter seasons. Patients hospitalized for cardiopulmonary conditions during that period were also studied. Overall, 44 (4.5%) of 984 illnesses were associated with hMPV infection, and 9 (4.1%) of 217 asymptomatic subjects were infected. There was a significant difference in rates of hMPV illnesses between years 1 and 2 (7/452 [1.5%] vs. 37/532 [7.0%]; P<.0001). In the second year, 11% of hospitalized patients had evidence of hMPV infection. Infections occurred in all age groups but were most common among young adults. Frail elderly people with hMPV infection frequently sought medical attention. In conclusion, hMPV infection occurs in adults of all ages and may account for a significant portion of persons hospitalized with respiratory infections during some years.  相似文献

Ratings of imagery value for 100 words were obtained from young and elderly adults. The ratings of elderly adults correlated highly with the ratings of young adults for both the present group and the normative group employed by Paivio, Yuille, and Madigan [4], indicating the generalizability of young adult norms to the population of elderly adults. In addition, the ratings of elderly adults were unrelated to variation in age, educational level, or vocabulary score.  相似文献

Young and elderly adults were tested for inferential and verbatim recall from a list of unrelated sentences. All participants performed an encoding task (pleasantness rating or comprehension task) during input and, at test, attempted to answer a series of who questions. Half of the questions required verbatim recall; the other half could only be answered on the basis of an inference from an input sentence. For both types of question, young adults recalled more than elderly adults. Age differences were larger after pleasantness rating than after the comprehension task for both kinds of recall, suggesting that any benefits of comprehension encoding are not the result of specific attention to inferences but, more generally, result from the meaning integration or unique representation created for each sentence. Analyses of conditionalized recall (i.e., recall given a particular level of similarity between comprehension encoding and experimenter's subsequent inferential cues) showed that old adults were less likely than young adults to use inferential recall cues highly similar to their own comprehension responses.  相似文献

The present paper examines reported frequencies of 21 health practices, beliefs that these health practices can prevent six different illnesses, and beliefs about those illnesses in a community sample of 396 people: 173 young (20 to 39 years), 111 middle-aged (40 to 59 years), and 112 elderly adults (60 to 89 years). Elderly respondents report higher frequencies of health-promoting actions (e.g., regular medical check-ups, avoidance of salt, regular sleep, and eating a balanced diet) than younger respondents. Health practices aimed at reinterpreting stress and controlling emotions (e.g., avoiding emotional stress, staying mentally alert and active) also increased with age. Belief that these 21 practices prevent specific illnesses was consistent across the three age groups. Beliefs about the six illnesses were consistent across age with three exceptions: Elderly people considered themselves more vulnerable to disease, saw it as more serious for them, and were less likely to use chronic mild symptoms, like weakness and aches, as illness warnings.  相似文献
