Professional and scientific work will increasingly be conducted at computer workstations. An expert-system adaptive interface is one method for supporting learning and raising productivity of workstation activities. A prototype application for an adaptive interface is described in terms of machine intelligence, needs, design philosophy, and cognitive research. The intelligent interface prototype includes the operator’s psychometric profile, prior performance history, and a current keystroke performance stack within a conventional expert system. Productions in the form of conditionals between the operator’s keystrokes and three types of commands to the underlying software are described and illustrated. Commands entered, syntax errors, excessive repetition of keystrokes, and skill level are used to detect the user’s intentions and accordingly modify the display and command structure of the underlying software. Determining human intentions to produce machine adaptation to individual users is not a trivial task. Efforts to develop a powerful and general adaptive interface pose significant problems, and success cannot be assured without intensive cognitive research. 相似文献

ABSTRACT The article by Bissonnette, Ickes, Bernstein, and Knowles (1990) presented in this issue contains a series of simulations which vary widely in the degree to which they resemble the parameters that have been found in actual data. Their conclusions feature warnings based on simulations containing large confounds between trait extremity and item variance. In real data, however, the corresponding confounds typically have been small. When Bissonnette et al. used appropriately small confounds in their simulations, their results showed that median split techniques failed to inflate Type I error rates. The constructive implications of Bissonnette et al.'s simulations indicate that moderator-variable researchers should always perform a simple check for range restriction and for variance-extremity confounds, and that there is no danger of spurious conclusions as long as these checks conform to what has typically been found with real data. 相似文献

Family rituals express patterned, repeated, symbolic communication that is ordered, evocative, socially meaningful, and directly impacts upon family functioning. Seasonal celebrations, rites of passage, family traditions, and patterned family interactions serve to organize the family, mediate individual expectations, regulate family subsystems, and facilitate change. Clergy and psychotherapists can use an understanding of family rituals to better understand individuals in their family context, promote change through prescribing rituals, and help clients create new, healing rituals. 相似文献

In the present study, we examined the effects of perceived overqualification on health and the moderating effect of emotional support. Exploratory and confirmatory factor analyses found 2 indicators of perceived overqualification: "mismatch" and "no-grow." Perceived mismatch had a significant negative effect on health but perceived no-grow did not. The main effect revealed that the greater the perceived emotional support, the greater the health. The significant interaction of perceived emotional support and mismatch, and perceived emotional support and no-grow on health indicates that the negative effects of overqualification on health was greater for those perceiving low emotional support than for those perceiving high emotional support. The significance of social support in illuminating the relationship between perceived overqualification and health are discussed. 相似文献

Abstract— Procrastination is variously described as harmful, innocuous, or even benefical. Two longitudinal studies examined procrastination among students. Procrastinators reported lower stress and less illness than nonprocrastinators early in the semester, but they reported higher stress and more illness late in the term, and overall they were sicker. Procrastination thus appears to be a self-defeating behavior pattern marked by short-term benefits and long-term costs. 相似文献

The study compared the effect of five persuasive appeals used in AIDS PSAs and condom commercials (fear arousal-no sex/condom theme; fear arousal-sex/condom theme; erotic; humorous; factual) on 122 male and 114 female college students' i]ntentions to use and taking of condoms. Results showed that the two fear appeals were more effective than other appeals in increasing intentions to use condoms with a new partner. The fear appeal–no sex/condom theme was more effective than other appeals for increasing intentions to use condoms with a steady partner. Compared to men, women rated commercials as more effective for increasing intentions to use condoms with a new partner. Persuasive appeals had no effect on the taking of free condoms. The best predictor of commercial effectiveness was the degree to which a commercial evoked a high fear of AIDS. Other significant predictors were subjects' a]ttitude toward condom use and commercial qualities of being humorous, romantic, credible, and factual. Implications are that all five types of appeals are potentially effective for use in AIDS PSAs. Recommendations include combining appeals (e.g. fear with erotic) and emphasizing the positive features of condom use. 相似文献

Familial similarity for suicidal behavior has been interpreted by psychosocially oriented researchers as reflecting extreme grief following loss. This view would anticipate a higher frequency of attempted suicide among bereaved MZ than DZ twins (regardless of cause of death), given their generally increased social closeness. Alternatively, support for a genetic influence on suicidal behavior has been provided by findings of greater concordance among monozygotic (MZ) than dizygotic (DZ) twins, and among biological than adoptive relatives. This approach predicts that the occurrence of suicidal attempts among bereaved MZ and DZ twins whose co-twins deaths were non-suicides should not differ and should be low in frequency, given an absence of predisposing genetic factors. Attempted suicide was compared in 166 MZ and 79 DZ twins whose co-twins' deaths were non-suicides. Suicidal attempts (during the first two months following the loss) were recalled by 3 MZ twins (1.8%) and by 3 DZ twins (3.7%), a difference that was not significant. The present study, together with previous twin and adoption studies, supports the view that concordance for suicide among family members reflects a common genetic predisposition to suicidal behavior. 相似文献

This report tested whether those individuals with a cluster B DSM-IIIR personality disorder (narcissistic, borderline, antisocial or histrionic) had higher scores for aesthetic preference for visually complex drawings using the Barron-Welch Art Scale. In a sample of 141 patients and controls, the 56 subjects who met the criteria for one of the cluster B personality disorder diagnoses displayed higher Barron-Welch Art Scale Scores. A multiple regression analysis showed that narcissistic and borderline personality disorder contributed positively, while dependent personality disorder, negatively to preference for complexity. The findings support the notion that aesthetic choices and values reflected through the dimension of openness to experience may contribute to the behavioral manifestations of the personality disorders. 相似文献

The results of empirical research in psychology and psychiatry are increasingly being used to formulate as well as understand problems at the interface of law and psychiatry. There has been a proliferation of studies, such as the determinants of individual competence or threat to self or others, the results of which are influencing policy and legislative decisions as well as buttressing holdings in court cases. In this article, I explore the issues of interpretation of epidemiological studies, particularly the role of ideological positions on the design and results of empirical findings, the importance of the way data are interpreted, and the role of ideologies in the way research findings are presented to provide support for policy positions. Two levels of analysis are involved in determining the validity of a study. The first addresses the questions of whether the study meets the statistical and epidemiological requirements for reliable results. These include considerations such as the appropriateness of the study design and methods for gathering and interpreting data. The second focuses on the underlying framework of the study. This involves factors such as the perspectives and values of those conducting the study, the explicit and implicit dominating ideologies where they operate, and the extent to which the study is constructed to reaffirm specific ideologies. This level of analysis is essential for disclosing the influences of ideologies on the results of studies and the way in which data are interpreted. In this article, I try to demonstrate through critiques of selected studies that the first stage of analysis is insufficient without an examination of underlying preconceived values to establish the meaningfulness of results. 相似文献
