Conflict and the Stochastic-Dominance Principle of Decision Making   总被引:1,自引:0,他引:1  
One of the key principles underlying rational models of decision making is the idea that the decision maker should never choose an action that is stochastically dominated by another action. In the study reported in this article, violations of stochastic dominance frequently occurred when the payoffs produced by two actions were negatively correlated (in conflict), but no violations occurred when the payoffs were positively correlated (no conflict). This finding is contrary to models which assume that choice probability depends on the utility of each action, and the utility for an action depends solely on its own payoffs and probabilities. This article also reports, for the first time ever, the distribution of response times observed in a risky decision task. Both the violations of stochastic dominance and the response time distributions are explained in terms of a dynamic theory of decision making called multiattribute decision field theory.  相似文献

Data from three experiments are reported in which recognition memory for active and passive sentences is compared. The results consistently show no difference, a result taken to invalidate syntactic memory hypotheses (e.g., the kernel plus tag and markedness hypotheses) which assume that the stored representation of passive sentences is more complex than that of active sentences. Previous reports of superior recall of active sentences are attributed to a reconstructive bias. One form of propositional hypothesis and a verbatim hypothesis are consistent with the data.This research was supported by Grant MH 19859 from NIMH to the first author, and by Rutgers University Research Council grants to both authors.  相似文献

Greater continuity in cognition between children and adults may exist than is usually appreciated. It was thought that after 3 to 4 years of age, the problem in switching on the dimensional-change card-sort task disappears. We show here, however, that if speed is used as the dependent measure, the effect of the first dimension is evident even in adults. Adults, like preschoolers, show difficulty in switching from a block of sorting by color or shape to a block of sorting by the other dimension. Notably, performance throughout the session was affected by the first dimension by which stimuli were sorted. We hypothesize that perhaps adults never fully outgrow any of the cognitive and perceptual biases of infancy and early childhood. Other examples of such biases that appear to still be present in adults are discussed. Conversely, the assumption that the optimal dependent measure for adults is the most sensitive measure for children is questioned.  相似文献

The purpose of this clinical article is to discuss aspects of the analysis of a child whose adoption functioned as organizer of her personality. Her fantasy life, defensive organization, sense of self and other, and object relations were all organized around a personal mythology surrounding her adoption. These organizing myths took various forms that emerged in the course of the analysis. Her adoptive parents also created a mythology that had a critical impact on the child's development and on their development as parents. The analytic work demonstrates how these organizing mythologies governed the parent–child relationship and how the collision of their mythologies led to a breakdown in the child's development and in parental functioning. In the course of the analysis, the child developed the capacity to grieve and to react to loss in an organized way as progressive development was restored and she was able to feel valued and loved. Her parents began to grieve the dual loss of not having biological children or a perfect adoption, and to develop more motherly and fatherly feelings for their child.  相似文献

Factors that may predict that a child will become a creative writer as an adult are explored. Two areas of research are reviewed: studies documenting the incidence of mood disorders in adult creative writers and retrospective studies examining the childhoods of creative writers. The first body of research shows a clear correlation between creative writing and mood disorders. The second shows that children who later become creative writers experience an atypical amount of stress. It is suggested here that these 2 findings are related, because stress in childhood is associated with mental illness in adulthood. Stress cannot however be a necessary condition for becoming a creative writer because not all creative writers experienced stress in childhood. Nor can it be a sufficient condition since most children who experience stress do not become writers. It is argued that, along with the stress that many writers experience as children, 3 factors may be associated with creative writing ability: growing up in an enriched and child-centered family (which can co-exist with stress), having high verbal ability, and having an unusually rich imaginative life. These latter 3 factors may mediate against stress and foster resilience in these children and allow them to grow up to become writers.  相似文献

Philip Johnson's masterpiece--the Glass House--is compared to a dream and conceptualized as containing encrypted and embedded representations of the self. Freud's masterpiece--The Interpretation of Dreams--is the theoretical and methodological model for this approach to design-as-dream. Drawing on Johnson's words and forms set in biographical, historical, and cultural context, interpretive paths are traced from manifest design elements of the Glass House to overdetermined latent meanings, yielding new and surprising insights into the Glass House, its elusive architect, and the process of its design. A mirror that reflects an image, a lens that focuses it, and a prism that reveals its components, the Glass House turns a lucid eye onto its maker.  相似文献

The main objective of this study was to identify how bereaved mothers describe their coping strategies in their own words. The literature on parental bereavement is sparse, and the present study aims to add to existing knowledge by eliciting the mothers' experiences covering a wide range of child ages including infants, younger children and adults. Semi-structured interviews were held with 13 bereaved mothers in the UK. Causes of death include accident, illness and suicide. The methodological approach was interpretative phenomenological analysis (IPA). This article reports two inter-related recurrent themes: (1) Continuing the bond with the deceased child and (2) Ambivalence to personal mortality. Participants reported that the relationship with their child was continued in a variety of ways, from tending to the grave and the child's remains, through linking objects or by establishing a symbolic representation of the child within their daily lives. All mothers talked openly about their own mortality, either demonstrating ambivalence about their own death, or expressing clear suicidal ideation. Death was seen as a release from living with the pain of loss. The presence of surviving siblings appeared to moderate suicidal ideation, but mothers expressed concerns about their ability to care adequately for other family members during times of intense grief.  相似文献
