Three experiments showed that, in virtual space, humans learn to find an invisible target that remains in a fixed location relative to distal cues. Experiment 1 showed that people rapidly learned to locate an invisible target in a computer-generated virtual arena. Participants searched the appropriate place intensely when, on a probe trial, the target was removed. Experiment 2 showed that two groups of participants, one with a visible and one with an invisible target, learned to locate the target in the virtual arena. A probe trial, during which the target was removed, showed that participants from both groups searched the former location of the target in the virtual arena, suggesting the presence of proximal cues did not interfere with place learning. Experiment 3 showed that, following place learning, people directly approach the location of the invisible target from novel start positions. The data were discussed in terms of spatial learning and memory. 相似文献

The issue of dual relationships is a significant ethical challenge for all counselors. For the counselor recovering from an addiction to substances, this issue can be even more problematic. Existing codes of ethics offer insufficient guidance to the recovering counselor. Following an overview of dual relationships, the author reviews the ethical codes of the American Counseling Association and the National Association of Alcoholism and Drug Abuse Counselors, with particular attention paid to their applicability to the recovering counselor. Potentially difficult situations are considered, and recommendations are offered both for the recovering counselor and for the counseling field in general to minimize the incidence of unethical behavior due to dual relationship issues. 相似文献

We randomly assigned college students to conditions in which they learned that they had gum disease, were at risk of having gum disease, or did not have gum disease. Then we examined their coping responses both immediately after the diagnosis and 2 days later. Students that told they had gum disease saw the disease as more prevalent than students in the other conditions; students identified as at risk saw the disease as more common than students who were told they had no disease. In addition, disease and at-risk diagnosis subjects believed that the disease was less serious but, during the 2-day interval between tests, they reported experiencing more bleeding–a symptom of gum disease. All of these responses to diagnosis were similar immediately after diagnosis and 2 days later. The data support a model of how persons react to illness signs (Ditto, Jemmott, & Darley, 1988) and have practical implications for dental professionals involved in diagnosing gum disease. 相似文献

The present study addresses a relatively unexplored area by examining older consumers' interface with product owner manuals. Specifically, compared to younger consumers, seniors evidenced significantly greater usage of manuals and readership of specific sections. Overall, regression analyses utilizing context, product characteristic, product familiarity, general perceptions of manuals and demographic variables as predictors of manual use found prior knowledge and the perception that manuals are helpful to be among the most significant variables explaining readership. In general, these same variables reflect the extent of overlap between factors explaining manual usage for both older and younger consumers. Relevant literature from related domains provides the context for a discussion of findings and areas for future research.The authors wish to thank Dr. Dixie Mills for her input in the early stages of this research. 相似文献

What frames of reference (assumptions, values, and belief systems) are used by municipal decision makers to guide their assessments of management innovations? Are frames of reference related to an actor’s position in an interpersonal communication network? Can the study of frames of reference and communication roles be combined in a new “sociocognitive network” approach to the study of innovation adoption and diffusion? This study addresses these questions in the context of local government decision making. The results suggest that a sociocognitive network approach, which considers both frames of reference and communication roles, holds significant promise as an element in multivariate representations of innovative behavior. The results of this study are best viewed as contributing to theory development in research on innovative behavior in organizational decision making. Additional research will be required to test and refine this theory in other organizational contexts. 相似文献

The relationship between the Woodcock-Johnson Tests of Cognitive Ability (WJTCA) and Wechsler Intelligence Scale For Children-Revised (WISC-R) was investigated in a referral sample of 52 elementary aged students. The WJTCA and WISC-R provided comparable ability estimates as reflected by a .74 correlation between the respective Full Scale scores and no significant (.05 level) mean difference (WJTCA Broad Cognitive Ability mean = 97.1, WISC-R Full Scale mean = 96.8). The comparability of the WJTCA/WISC-R global ability estimates is contrary to lower WJTCA scores found in recent studies with learning disabled students, with the current findings supporting the criticism of those studies as advanced by the author of the WJTCA. 相似文献

This report is an examination of a theoretical model of risk amplification within a sample of 255 homeless and runaway adolescents. The young people were interviewed on the streets and in shelters in urban centers of four Midwestern states. Separate models were examined for males (n = 102) and females (n = 153). Results indicated that street experiences such as affiliation with deviant peers, deviant subsistence strategies, risky sexual behaviors, and drug and/or alcohol use amplified the effects of early family abuse on victimization and depressive symptoms for young women. These street adaptations significantly increased the likelihood of serious victimization over and above the effects of early family history for both young men and women. Similarly, street behaviors and experiences increased the likelihood of depressive symptoms for young women over the effects of early family abuse, but not for young men. The risk-amplification model from the life course theoretical perspective is discussed as an example of the cumulative continuity of maladaptive behaviors. 相似文献

Understanding and Evaluating Bureaucratic Politics: The Nexus Between Political Leaders and Advisory
Bureaucratic politics—for example, the "political" interaction between individuals and organizations in the executive branch of government—is a potentially significant force affecting the course and outcomes of governmental policymaking processes. In this article, an empirical and normative model and operationalization of bureaucratic politics is developed, treating it as a variable rather than as an immutable (and by definition problematic) property of policy decision-making. A conceptual model, linking the nature and intensity of bureaucratic politics in advisory systems to the characteristics of the political leaders served by them, is also developed. On the basis of earlier studies of presidential leadership (e.g., Preston, 1996), the leader's need for power, cognitive complexity, and prior policy experience/expertise are hypothesized to affect the organization and operation of the advisory system in terms of bureaucratic politics. Using Hermann's (1983) Personality Assessment-at-a-Distance (PAD) coding technique, theoretical assertions are illustrated in a detailed case study of two critical episodes in U.S. decision-making in the conduct of the Vietnam war in 1965 and 1968. 相似文献

The attitudes of twenty-nine managers toward performance appraisal and toward their organization were used to predict differences in mean ratings and measures of discrimination among ratees and performance dimensions. Substantial multiple correlations were obtained for all three dependent variables (between 32 and 46% of the variance in each measure was explained), and several individual correlations were statistically significant. Raters who showed low levels of confidence in the appraisal system, high levels of discomfort, or high levels of instrumental commitment were more likely to provide ratings that were unusually high or that did not discriminate well among ratees and/or dimensions. Raters who showed higher levels of attitudinal commitment or who perceived more risks associated with distorting ratings tended to provide lower ratings and to discriminate among ratees and/or dimensions. 相似文献
