Even if together we could make poverty history, we would not all do our part. The paper presents a device that makes it more
likely for everybody to do his part. This is achieved by making everybody’s contribution dependent on the other people’s commitment
to contribute given that certain conditions are fulfilled. Furthermore, a device is introduced which, based on the same general
idea, doubles everybody’s donation. Finally, possibilities, assumptions and limitations of such devices are addressed. 相似文献

A qualitative research‐based diagnostic procedure, the Priority‐Pointing Procedure (PPP), is proposed that synthesizes responses to open‐ended questions about the direction an organization should take. It points to a priority for action by measuring imbalances in the numbers of responses in the context of the structure of adjustment decision‐making from nomology. It is shown to be useful for defining variables and structuring criteria for strategic Multi‐Criteria Decision Analysis (MCDA) problems. Copyright © 2000 John Wiley & Sons, Ltd. 相似文献

In two experiments, one conducted at an individual level and one at a group level, it was investigated how decision strategies and the reception of decision-threatening information affect the degree of post-decision consolidation for both individual and group decision-makers. In Experiment 1, roughly half the 55 participants made decisions in three-person groups and the other half individually. The type of decision strategies subjects employed (compensatory, non-compensatory, other) was assessed by questionnaire. In two post-decision sessions, consolidation was assessed using a memory task, either decision-supporting or decision-threatening information being provided at the start of the last post-decision session. In Experiment 2, the same design and procedure were used at a group level. In both experiments, the groups (and the single group members) were analyzed with the SYMLOG instrument. The results indicated that individual decision-makers consolidated their own decisions more than members of decision-making groups. There was also greater post-decision consolidation with the use of non-compensatory decision strategies as well as with reception of decision-threatening information, this latter result being seen as providing an explanation for the greater consolidation that individual decision-makers showed. Furthermore, single task-oriented group members and groups with a task-oriented leader consolidated the decision made by their group. 相似文献

The recognition heuristic (RH) claims that people base inferences on recognition only. This has been questioned by several studies which found that additional knowledge was influential. However, in some of these studies, participants' additional knowledge might have encompassed criterion knowledge thus rendering any inferential strategy superfluous. The present study was therefore designed to test the effect of criterion knowledge on use or non‐use of the RH. Eighty‐one participants made pair‐wise comparisons with respect to the size of Belgian cities and also provided estimates of the cities' actual size. We found that relative criterion knowledge (i.e., knowledge about the relative position of an object on the criterion dimension) did indeed play some role, but its exclusion left the main critical findings intact, nonetheless. We thus conclude that previous studies conducted in the paradigm of natural recognition should not be generally refuted by the argument of participants possessing criterion knowledge.

Previous research has shown that positive affect (PA) is associated with the coping strategies of \"searching for and finding positive meaning.\" The purpose of this study was to investigate the relationship between the coping strategy of \"finding positive meaning\" and PA using an intervention method. Additionally, inasmuch as previous research has revealed that PA is associated with physical and mental health status, the current study measured health status in order to carry out a preliminary test as to whether PA increased by the intervention can also improve health. Participants in the intervention group (Japanese graduate students; 13 men and 16 women) reported the most stressful event during the past 3 days and its positive meaning, while those in the control group (13 men and 15 women) reported the most stressful event alone. Both groups reported twice a week for 5 successive weeks using e-mails. Three questionnaires, the Japanese version of the Positive and Negative Affect Schedule scales for measuring positive and negative affects (NA), the situational version of the General Coping Questionnaire for coping strategies, and the Japanese version of the General Health Questionnaire for health status, were administered to all participants just before the start of the intervention, after the conclusion of the intervention, and at the 5-week follow-up session. Results revealed that the \"finding positive meaning\" coping strategy and PA were enhanced by the intervention in the follow-up for men and women with no changes in NA. For the health scales of the General Health Questionnaire, no significant group-related effects were observed. Thus, the intervention had no significant influence on NA or health status. Implications of these findings for future research are discussed along with a few limitations in this study. 相似文献

Indecisiveness is a trait‐related general tendency to experience decision difficulties across a variety of situations, leading to decision delay, worry, and regret. Indecisiveness is proposed (Rassin, 2007) to be associated with an increase in desire for information acquisition and reliance on compensatory strategies—as evidenced by alternative‐based information search—during decision making. However existing studies provide conflicting findings. We conducted an information board study of indecisiveness, using eye tracking methodology, to test the hypotheses that the relationship between indecisiveness and choice strategy depends on being in the early stage of the decision making process, and that it depends on being in the presence of an opportunity to delay choice. We found strong evidence for the first hypothesis in that indecisive individuals changed shift behavior from the first to the second half of the task, consistent with a move from greater to lesser compensatory processing, while the shift behavior of decisive individuals suggested lesser compensatory processing over the whole task. Indecisiveness was also related to time spent viewing attributes of the selected course, and to time spent looking away from decision information. These findings resolve past discrepancies, suggest an interesting account of how the decision process unfolds for indecisive versus decisive individuals, and contribute to a better understanding of this tendency.

The authors investigated the effects of voluntary and automatic control on the spatial variables (envelope area, maximal amplitude, and root mean square [RMS]) of center of pressure (COP) displacement during quiet standing and identified differences in their postural control strategies (mean velocity [MV], mean power frequency [MPF], and power density). COP data were recorded under relaxed (experimental control), still (voluntary control), and dual (automatic control) conditions. RMS was significantly lower in the still and dual conditions than in the relaxed condition. MV, MPF, and power density were significantly higher in the still condition than in the dual condition. These results indicate that both voluntary and automatic control decrease the spatial variables of COP displacement; however, their postural control strategies are different. 相似文献

ABSTRACT This study examined time-based prospective memory performance in relation to age, monitoring strategy, response accuracy, and dual-task demands. Young, middle-aged and older adults (N?=?115) completed a prospective memory task, in which they indicated the passing of time every 5 min while listening to a short story (low task demands) or completing a series of cognitive tasks (high task demands). Young and older adults showed similar patterns of monitoring behavior, with low rates of clock checking during the early phase of each 5-min interval, followed by linearly accelerating monitoring functions. However, to obtain the same level of prospective memory performance older adults needed more frequent clock checks than young adults. Furthermore, older adults' compensatory monitoring strategy was associated with an additional cost in primary task performance. Finally, increased primary task demands shifted age differences in prospective memory from monitoring frequency to response accuracy. These findings suggest that goal-directed behavior requires efficient task coordination and resource allocation, and that age-related differences in time-based prospective memory should be evaluated by using multiple outcome measures. 相似文献
