The purpose of this study was to explore the definition of fetal viability and the availability, indications, and decision making processes for post-viability termination of pregnancy for fetal abnormalities and health conditions in Canada. An online survey of members of the Canadian Association of Genetic Counsellors, the Canadian College of Medical Geneticists, and the Canadian Society for Maternal-Fetal Medicine who provide direct counselling to, or management of, prenatal patients in Canada (total sample size 815). Results of this study showed that the majority of respondents indicated that their centre will offer post-viability termination of pregnancy (98/123; 80 %). Sixty-seven percent (68/101) of respondents reported the definition of fetal viability to be 24 weeks’ gestation. Most respondents reported that a collaborative decision making process was used to determine if post-viability termination of pregnancy would be offered (136/170; 80 %). For conditions presumed to be lethal/likely lethal, the majority of respondents would “sometimes” or “always” offer post-viability termination of pregnancy, whereas for conditions presumed to have a mild effect, the majority of respondents would “rarely” or “never” offer post-viability termination of pregnancy. Ninety percent (77/86) of respondents reported that perinatal hospice is offered as an alternative to termination of pregnancy. In conclusion, this study suggests that although post-viability termination is available in many provinces in Canada, variation in the definition of fetal viability and indications appear to exist. While these variations may lead to unequal access to post-viability termination of pregnancy across Canada, they might also represent the complexity of the decision making process and the importance of examining individual factors to ensure that the most appropriate decision is made in each case.  相似文献

The influence of alternative labels on decision processes and outcomes were examined in a multidimensional decision task with realistic decision information and experienced decision makers. Based on prior research, it was predicted that labels would influence selection and ratings of decision alternatives, as well as the extent of information search and the information search strategies. Subjects (n = 26) experienced in making and/or aiding business relocation decisions completed two computer controlled site selection tasks: one with labeled locations and one with unlabeled locations. Results indicated that labeling influenced both decision processes and location ratings. An interaction between order of task completion and labeling suggested that labeling effects on decision making may be minimized if an unlabeled task is completed prior to a labeled task. Implications and limitations are discussed in terms of labeling effects and decision quality.  相似文献

Many models of decision making neglect emotional states that could affect individuals' cognitive processes. The present work explores the effect of emotional stress on people's cognitive processes when making probabilistic inferences. Two contrasting hypotheses are tested against one another: the uncertainty‐reduction and attention‐narrowing hypotheses of how emotional stress affects decision making. In the experimental study, emotional stress was induced through the use of highly aversive pictures immediately before each decision. Emotional state was assessed by both subjective (state anxiety, arousal, and pleasantness ratings) and objective (skin conductance) measures. The results show that emotional stress impacts decision making; in particular, emotionally aroused participants seem to have focused on the most important information and selected simpler decision strategies relative to participants in a control condition. The results are in line with the attention‐narrowing hypothesis and suggest that emotional stress can impact decision making through limited predecisional information search and the selection of simpler decision strategies.

This study examines the crime patterns of 76 New Zealand serial sexual offenders in order to determine the extent to which offenders display locational consistency in their choice of crime locations. More specifically, the hypothesis was that there would be intraseries consistency in the distances travelled (spatial consistency) and the characteristics of the crime sites selected (environmental consistency) by serial sexual offenders. For spatial consistency to be tested, the distances travelled from home to offend and the criminal range for each offence series were analysed. Support was found for spatial consistency, and, in line with much overseas research, it was also found that the offenders typically did not travel very far from home to offend (median distance of 3 km). The environmental consistency measure was made up of various physical, temporal, and contextual variables that described the environmental characteristics of an offence. As hypothesised, it was found that offenders displayed intraseries environmental consistency in offence site selection beyond the level of that expected by chance. The implications of this both for understanding offender spatial decision making and for geographical profiling are discussed. Copyright © 2009 John Wiley & Sons, Ltd.  相似文献

Multiple criteria group site selection problems involve a group of individuals evaluating a set of alternative sites on the basis of multiple criteria. This paper presents an application of a new fuzzy algorithm for finding and exploring potential solutions to these problems in a raster Geographical Information System (GIS) environment. Linguistic assessments from decision‐makers are represented as triangular fuzzy numbers (TFN's), which are adjusted for uncertainty in the source data and their relationship to suitability by using an approach based on type‐2 fuzzy sets. The first aggregation of inputs is a compensatory one based on fuzzy multiattribute decision‐making (MADM) theory. An adjusted aggregation then factors in conflicts, risks and uncertainties to enable a variety of compensatory and non‐compensatory outcomes to be generated based on decision‐maker preferences. The algorithm was implemented in ArcView GIS as part of an ongoing collaborative project with Brisbane Airport. This paper outlines the fuzzy algorithm and its use in site selection for a recycling facility on the Brisbane Airport site. Copyright © 2005 John Wiley & Sons, Ltd.  相似文献

Decision making requires evaluating alternatives that differ on a number of attributes. During this evaluation process, selection of options depends on the duration of the options, the duration of the expected delay for realizing the options, and the time available to reach a decision. This article reviews the relationship between time and decision making in humans with respect to this evaluation process. Moreover, the role of psychological time, as compared with physical time, is accentuated. Five topics have been selected that illustrate how time and mental representations of time affect decision making. These are (1) the duration of options, (2) temporal decision making, (3) the time between having made a decision and experiencing the consequences of that decision, (4) the temporal perspective of decision makers, and (5) the duration of the decision process. The discussion of each topic is supplemented by suggestions for further research. It is shown that psychological time is often neglected in human decision making but seems to play an important role in the making of choices.  相似文献

The relationship between education and the importance of religion in everyday decision making is examined using data from two national surveys of American adults. People who have higher levels of education are less likely to rely on the Bible and the teachings of their place of worship for guidance in their decision making. However, previously undocumented contingencies attenuate the effect of education: (1) attending religious services regularly; (2) involvement in religious activities; (3) praying more frequently; (4) believing in the literal interpretation of the Bible; and (5) greater certainty in one's personal faith. These patterns hold net of income, which is also negatively associated with religious‐based decision making—and only the socially integrative aspects of religiousness attenuate that association.  相似文献

In the field of eye tracking, scanpath analysis can reflect the sequential and temporal properties of the cognitive process. However, the advantages of scanpath analysis have not yet been utilized in the study of risky decision making. We explored the methodological applicability of scanpath analysis to test models of risky decision making by analyzing published data from the eye‐tracking studies of Su et al. (2013); Wang and Li (2012), and Sun, Rao, Zhou, and Li (2014). These studies used a proportion task, an outcome‐matched presentation condition, and a multiple‐play condition as the baseline for comparison with information search and processing in the risky decision‐making condition. We found that (i) the similarity scores of the intra‐conditions were significantly higher than those of the inter‐condition; (ii) the scanpaths of the two conditions were separable; and (iii) based on an inspection of typical trials, the patterns of the scanpaths differed between the two conditions. These findings suggest that scanpath analysis is reliable and valid for examining the process of risky decision making. In line with the findings of the three original studies, our results indicate that risky decision making is unlikely to be based on a weighting and summing process, as hypothesized by the family of expectation models. The findings highlight a new methodological direction for research on decision making. Copyright © 2016 John Wiley & Sons, Ltd.  相似文献

The Melbourne Decision Making Questionnaire (Mann, Burnett, Radford, & Ford, 1997) measures self-reported decision-making coping patterns. The questionnaire was administered to samples of University students in the US (N = 475), Australia (N = 262), New Zealand (N = 260), Japan (N = 359), Hong Kong (N = 281), and Taiwan (N = 414). As predicted, students from the three Western, individualistic cultures (US, Australia, and New Zealand) were more confident of their decision-making ability than students from the three East Asian, group-oriented cultures (Japan, Hong Kong, Taiwan). No cross-cultural differences were found in scores on decision vigilance (a careful decision-making style). However, compared with Western students, the Asian students tended to score higher on buck-passing and procrastination (avoidant styles of decision making) as well as hypervigilance (a panicky style of decision making). Japanese students scored lowest on decision self-esteem and highest on procrastination and hypervigilance. It was argued that the conflict model and its attendant coping patterns is relevant for describing and comparing decision making in both Western and Asian cultures.  相似文献

Although the same decision to act can occur in multiple contexts, how these contexts differentially influence behavior is not well understood. In this paper, we investigate whether contextual framing affects individuals' behavior in spatial decision making. Although previous research suggests that individuals' judgments are sensitive to contextual (and particularly moral) factors of a scenario, no work has addressed whether this effect extends to spatial decisions. To investigate the impact of context on perceptual sensorimotor behavior, we superimposed two moral dilemmas (which we call help and harm) on a spatial decision-making paradigm. The basic task required participants select a target area while avoiding an overlapping nontarget area. Although the visuospatial task was constant, the moral context was changed when participants had to execute either a drone missile strike on enemies in the harm context or deliver ammunition to allies in the help context. Participants more strongly avoided losses in the harm context, reflected by a greater selection bias away from the nontarget (i.e., allies) on drone strike trials. These findings suggest that the contextual framing of a subjective perceived loss on a spatial decision can drive avoidant motor execution behavior.  相似文献

Abstract

Top decision making processes are generally depicted as chaotic, unstructured, incremental or spasmodic, and protracted. In this article it is shown, based on data from 25 strategic decision processes from 12 organizations in three industry sectors, that, within certain limits, there certainly are control options in strategic decision-making processes. In addition, their use tums out to be profitable. The analyses of patterns in the use of control dimensions in the 25 cases leads to a typology of four types of decision models or strategies: the neo-rational model (n = 3), the bureaucratic model (n = 4), the arena model (n = 8) and the open-end model (n = 10). This empirical typology confirms earlier typologies based on literature.

The use of control strategies is shown to vary across industry sectors and topics of decisions and have adifferential effect. It is concluded that context and content variables have either a selection effect (some strategies do not occur in some sectors) or a optimization effect (some strategies are more effective than others in a given context).  相似文献

This paper puts forward the position that the cognitivist approach adopted in research on decision making in team sports leads to a disconnection from the actual environment of play. The argument is structured as a narrative review of 60 articles that were analyzed to identify the most recent concepts related to the following topics or combinations thereof: tactics and action in the play; decision making and associated cognitive mechanisms and skills; and the teaching–learning–training process. The results of the review led us to characterize decision making in the team sports context as being (a) “prereflected,” (b) based on evaluation, (c) frugal, and (d) “generated,” as opposed to being a process of choosing from alternatives. In addition to showing clear adjustments to the environment of play, the four characteristics imply that teaching, learning, and training to play should also be designed according to the restrictions imposed by the context and the actual lived experience of the play. We conclude that cognition should not be considered solely responsible for decisions, and thus both theoretical and pedagogical models of player development should take the ecological perspective of decision making into account. As a result, the methodologies employed to develop players from an early age could be elaborated on by taking into account the interaction between cognitive skills and the possibilities emerging in the play.  相似文献

Shared decision making (SDM) shares values of client-centered practice; however, a few studies exist that explore experiences of occupational therapists (OTs) working in adolescent mental health. This study aims to better understand SDM in adolescent mental health using the Canadian Model of Client-Centered Enablement. A qualitative study included interviews (n = 6) and analysis using an inductive approach. The role of the OT, client factors, therapeutic relationship, and nature of the decision were identified as influencing the process and outcome of SDM. The study helps better understand SDM in practice, the need for specialized education for OTs and has identified future research areas.  相似文献

Models of moral decision making describe the process as beginning with the recognition of moral content in the decision environment. This recognition ability, or moral sensitivity, represents a key input to moral decision making. Adopting a social cognitive perspective, this paper studies the degree to which moral sensitivity is explained in terms of moral schema activation. In a single experiment, two situational factors (moral content priming and issue moral intensity) and two individual characteristics (moral identity and need for cognition) are tested for their effects on moral sensitivity. Results support the social cognitive explanation of moral sensitivity. The moral schema's propensity for activation, development, and accessibility significantly influence the ability to recognize moral issues in the decision environment.  相似文献

This article describes the development and evaluation of a workshop program to help people become more confident and effective as decision makers. The workshops, based on conflict theory, consisted of five 2-hour sessions, in which participants learned about the major decisional coping patterns and the critical steps of decision making. Participants also practiced decision-making skills and learned how to use decisional balance sheets, future diaries, and other aids to vigilant decision making. The 76 participants were classified as “problem clients” (N = 44, “learners” (N = 30), and “others” (N = 2). A follow-up questionnaire administered 3 months after the final session revealed that the workshops had promoted increased confidence in decision making and less reported use of maladaptive patterns of decision making.  相似文献

Both the fast and frugal heuristics (FFHs) and the naturalistic decision making (NDM) research programmes have identified important areas of inquiry previously neglected in the traditional study of human judgment and decision making, and have greatly contributed to the understanding of people's real-world decision making under environmental constraints. The two programmes share similar theoretical arguments regarding the rationality, optimality, and role of experience in decision making. Their commonalities have made them appealing to each other, and efforts have been made, by their leading academics, to promote synergy and integration. However, there has been little progress towards this during the last decade. This paper seeks to address this gap by seeking to better understand their commonalities and differences. To do so, literature relating to the two programmes is reviewed. The findings of the review indicated that an integration of the two could enhance FFHs' field research in applied settings, facilitate its investigation on boundary conditions of people's decision strategy selection, enable NDM to embrace emerging research opportunities in the age of big data, as well as permit each programme to enlighten the research topics and to validate the research findings of the other.  相似文献

Are older adults' decision abilities fundamentally compromised by age-related cognitive decline? Or can they adaptively select decision strategies? One study (N = 163) investigated the impact of cognitive aging on the ability to select decision strategies as a function of environment structure. Participants made decisions in either an environment that favored the use of information-intensive strategies or one favoring the use of simple, information-frugal strategies. Older adults tended to (a) look up less information and take longer to process it and (b) use simpler, less cognitively demanding strategies. In accordance with the idea that age-related cognitive decline leads to reliance on simpler strategies, measures of fluid intelligence explained age-related differences in information search and strategy selection. Nevertheless, both young and older adults seem to be equally adapted decision makers in that they adjust their information search and strategy selection as a function of environment structure, suggesting that the aging decision maker is an adaptive one.  相似文献
