The goal of the research was to compare decisions under risk in a situation in which forecasters (F) communicate to decision makers (DM) either numerically (e.g., .70) or verbally (e.g., likely) about the chances that a binary event will occur. Following each forecast, the DM bid for a winning or losing lottery based on the event. In Experiment 1 Fs and DMs also provided numerical translations of each verbal forecast after the DMs' bid. In Experiment 2 the DMs provided membership functions over the [0, 1] interval for each phrase used by the Fs. The primary results were: (a) extreme similarity in the DM's bids and rates of bidding under the two modes of communication; (b) greater variability in bids to specific verbal than numerical forecasts; (c) a pattern of bids, in which DMs demonstrated risk seeking for gains and risk neutrality for losses; (d) DMs' numerical translations in Experiment 1 were closer to .50 than were those of Fs; and (e) phrases selected by Fs had high membership values to DMs for the probabilities the Fs were attempting to describe. Points (a), (b), (d), and (e) are consistent with the ν-μ model which assumes that the vague meaning of a probability phrase can be represented by a membership function over the [0, 1] interval, and that in reaching a decision the DM focuses on a range of probabilities with sufficiently high membership. Point (c) is speculatively attributed to social aspects of the dyadic situation, and requires further investigation. 相似文献

In this paper, we describe an apparatus for measuring reaction times and movement times involved in reaching for real objects. Subjects view an object through a liquid crystal window, which serves as a shutter that can be made clear or opaque quickly (10 msec from opaque to clear, 30 msec from clear to opaque). The subject’s hand rests on a microswitch-equipped home key, and the object sits on a force-sensitive platform so that initiation of reach and time of contact with the object can be marked accurately. The apparatus interfaces with an IBM PC/AT through a digital I/O parallel port, so that reaction times and movement times are recorded automatically. 相似文献

A therapeutic jurisprudence analysis attempts to discern the role of legal proceedings, lawyers and judges in producing therapeutic or anti-therapeutic consequences. This paper will attempt to use the therapeutic jurisprudence framework to analyze the legal and administrative aspects of court review as it was reported during a one year epidemiologic study of drug refusal. Characteristics of the review process, the effect on patient refusal, and the attitudes of treating psychiatrists are presented. To broaden the clinical context of the administrative findings, selected clinical characteristics of refusing patients, their attitudes toward mental illness, reasons for refusing medication and satisfaction with court review will be described. The discussion attempts to show how the initial administrative study findings may be interpreted in the broader context of their relationship to the achievement of therapeutic outcomes. 相似文献

The authors studied employment and roles of master's-level counselors in employee assistance programs (EAPs) and the services offered by different types of EAP organizations. The study focused on programs, workshops and seminars: assessment; counseling; consultation; and evaluation and marketing services offered by EAPs. Master's-level counselors were found to be similar to those with Master's of Social Work (MSW) degrees in employment rate and percentage of EAP staff. Both groups were the most frequently employed and constitute the greatest percentage of the professional mental health staff in EAPs. Also, counselors were found to be involved in all of the service areas studied within each type of EAP. Differences in counselors' roles among EAP types are discussed. 相似文献

A content-related test construction strategy was employed as a means of yielding a test with criterion-related evidence of validity. Utilizing a national sample of field sales job incumbents, a group-based job analysis method was developed to identify job requirements. A content validity and concurrent criterion-related study were then conducted. The results demonstrated both content and criterion-related evidence of validity. Differential validity by race or gender was not found. A comparison between minority and non-minority group regression lines found no statistically significant difference between slopes. However, a statistically significant difference between minority and non-minority intercept values was found. The results are discussed in respect to their consistency with other research findings. The significance of the study is addressed in light of the recent Unitarian approach towards the theoretical and practical nature of test validity. It is suggested that practitioners and researchers investigate further the elements of this research effort as guidance for satisfying professional and federal standards. 相似文献

This is an ecological test of adaptation in head-injured adults, reporting reliability and validity of the Executive Function Route-finding Task (EFRT; Boyd and Sautter, 1985). A Likert scale was used to rate executive aspects of route-finding such as task formulation, strategy of approach, detection and correction of errors, and dependence on cueing among 31 head-injured young adults within a large rehabilitation facility. The Task has high inter-rater reliability and acceptable concurrent validity with other neuropsychological constructs. 相似文献
