We examined whether subjects use base-rate information about item difficulty when making feeling-of-knowing judgments for items they failed to recall. First, the subjects attempted to recall the answers to general-information questions. Then, for those items they recalled incorrectly, half of the subjects received information about the normative probability of recall of each item while judging their feeling of knowing. The other subjects made their feeling-of-knowing judgments without receiving any base-rate information. Finally, all subjects had a forced-choice recognition test on those items to validate the accuracy of their feeling-of-knowing judgments. Relative to the no-base-rate information group, the base-rate group had lower feelings of knowing for normatively difficult items and higher feelings of knowing for normatively easier items. Subjects who had received base-rate information during the judgment state had greater feeling-of-knowing accuracy than subjects who did not receive base-rate information. However, even the predictions from subjects who received base-rate information were not significantly more accurate for predicting subsequent recognition than were the predictions derived from normative information alone. 相似文献

The research reported here examined the effect of personal belief systems of managers and their subordinates on their interrelationships as measured by several job-related satisfaction variables. Results from a sample of 175 manager-subordinate dyads demonstrate that the belief system construct may significantly affect job-related satisfaction as well as the quality and outcomes of manager-subordinate relationships. This research also suggests that socially oriented managers are positively associated with higher levels of subordinate satisfaction. 相似文献

Outcome measures for smoking cessation are reviewed and evaluated, including 3 self-report measures and 3 biochemical validation measures. Point prevalence reflects the percentage of participants taking action, prolonged abstinence reflects those in the maintenance stage, and continuous abstinence reflects those who progress from action to maintenance without lapsing or relapsing. Biochemical assessments are primarily measures of point prevalence abstinence. The desirability of biochemical validation is a particularly controversial and critical issue. Three factors affect the accuracy of self-report: Type of Population, Type of Intervention, and Demand Characteristics. False-negative rates are generally low. Three broad issues impact on decisions to use biochemical validation: (a) alternative explanations for false positives, (b) refusal rate problems, and (c) the effect of inaccuracy on intervention assessment. 相似文献

Classical factor analysis assumes a random sample of vectors of observations. For clustered vectors of observations, such as data for students from colleges, or individuals within households, it may be necessary to consider different within-group and between-group factor structures. Such a two-level model for factor analysis is defined, and formulas for a scoring algorithm for estimation with this model are derived. A simple noniterative method based on a decomposition of the total sums of squares and crossproducts is discussed. This method provides a suitable starting solution for the iterative algorithm, but it is also a very good approximation to the maximum likelihood solution. Extensions for higher levels of nesting are indicated. With judicious application of quasi-Newton methods, the amount of computation involved in the scoring algorithm is moderate even for complex problems; in particular, no inversion of matrices with large dimensions is involved. The methods are illustrated on two examples.Suggestions and corrections of three anonymous referees and of an Associate Editor are acknowledged. Discussions with Bob Jennrich on computational aspects were very helpful. Most of research leading to this paper was carried out while the first author was a visiting associate professor at the University of California, Los Angeles. 相似文献

The delayed-JOL effect is the finding in which judgments of learning (JOLs) are more accurate at predicting eventual recall when they are made a short time after study rather than immediately after study. The present research replicated this effect and found that the kind of cue that is used for JOLs is critical. In particular, following the study of stimulus-response paired associates, there is an extremely robust delayed-JOL effect when the cue for JOLs is the stimulus alone (every one of 45 subjects showed the effect); however, there is little, if any, delayed-JOL effect when the cue for JOLs is the stimulus-response pair. This finding has important implications for education: To have the greatest accuracy at predicting eventual recall, a person should make JOLs not immediately after study but, instead, shortly after study (i.e., delayed JOLs) with the cue for JOLs being the stimulus alone. The theoretical mechanisms for the delayed-JOL effect are currently unknown, but some speculations are offered. 相似文献

Conclusion We have illustrated how our small theory (Lipsey, 1990) of bereavement guided the development and evaluation of a preventive intervention for bereaved children. Our small theory, based on prior empirical research, enabled us to identify family processes that appeared to mediate the effects of parental death on child mental health. Our intervention was designed to attempt to change these processes. The evaluation of our experimental trial of the intervention assessed changes on these processes as well as the more distal mental health outcomes. The experimental trial showed some-what encouraging results, in terms of the program's ability to modify the warmth of the parent–child relationship and to decrease symptomatology in the adolescent children. We also obtained further empirical support for our underlying theoretical model. Finally, implications for redesign of the program were derived from assessing the adequacy of the program components to change each of the mediators in the theoretical model.Support for this research was provided by NIMH grant P5OMH39246 which is gratefully acknowledged.

Information was gathered by means of a questionnaire survey and interviews from a group of patients (N = 17) and health professionals (N=13) working within a stroke unit, concerning the emotional needs of patients and and their relatives and how staff responded to these needs. Although most of the staff had received some training or information about counselling and felt that their interactions with patients often involved an element of counselling, there was strong support for separate specialised counselling services to deal with psychological problems suffered by both patients and their relatives. Patients rated assistance with personal and emotional worries and advice about physical problems as equally useful. A strong need for a counselling service in some form or other was expressed by patients. Neither the level of the patients' social support nor the presence or absence of aphasia, however, predicted the strength of interest expressed. It is concluded that specialised psychological help could be useful in various ways for both in- and out-patients and for their families. 相似文献

This study tested whether sensitivity to aversive events is a concomitant versus antecedent/consequent of depression. Twenty currently depressed subjects, twenty subjects with remitted depression, and twenty control subjects completed psychophysiological and learning tasks involving aversive components. Both currently depressed and remitted subjects, when compared to control subjects, exhibited greater decreases in skin resistance response reactions to negative social scenes and a greater sensitivity to extinction in the learning condition involving an aversive component. The fact that the responses of remitted subjects were very similar to those of currently depressed subjects on both tasks is consistent with the view that sensitivity to aversive events is an antecedent or consequent of depression, as opposed to being only a concomitant. The results also provide some support for the passive avoidance model of depression.This study was based on portions of a doctoral dissertation by the first author, with the second author as chairperson, at the University of North Carolina at Greensboro.This research was aided by a Grant-in-Aid of Research to the first author from Sigma Xi, The Scientific Research Society, an award from the Jill Shelby Memorial Fund to the first author, and support from National Institute of Mental Health Grant MH17071, awarded to C.

In a study of how aviation expertise influences age differences in narrative processing, young and older pilots and nonpilots read and recalled aviation and general narratives. They chose referents for sentences referring to a protagonist or minor character mentioned 1 sentence (recent character) or 3 sentences (distant character) before this target sentence. All groups chose referents less accurately for sentences about distant and minor characters than about recent and protagonist characters, perhaps because these referents were less likely to be in working memory. Young readers and pilots were more accurate for distant and minor character target sentences in aviation narratives, and recalled aviation narratives more accurately. Expertise did not reduce age differences. Expertise differences may reflect decreased demands on working memory capacity, and age declines may reflect reduced capacity. 相似文献

Providing genetic services to families who do not speak English and whose cultures are quite diverse presents a unique challenge to genetic specialists. One approach that is being employed successfully is the use of specially trained genetic assistants to provide outreach, case finding, referral, support, interpretation, advocacy, and follow-up counseling. A basic genetic assistant training program for five bicultural/bilingual Southeast Asian case managers is described. The course syllabus can be used to train health workers who represent a variety of cultures and languages. 相似文献
