Although the sunk-cost effect is a well-documented psychological phenomenon in monetary investments, existing literature investigating behavioral investments (e.g., time, effort) has not replicated this effect except when such investments relate to monetary values. The current explanation for this discrepancy proposes that purely behavioral sunk-cost effects are unlikely to be observed because they are difficult to book, track, and balance in a mental account. Conversely, we argue that, through an effort-justification mechanism, people account for the amount of behavioral resources invested when selecting an alternative, in which case they may fall prey to purely behavioral sunk-cost effects. The results of two experiments support this prediction. Because many decisions involve behavioral investments, behavioral sunk-cost effects should be pervasive psychological phenomena. 相似文献

Normic Laws and the Significance of Nonmonotonic Reasoning for Philosophy of Science. Normic laws have the form ‘if A then normally B’. They have been discovered in the explanation debate, but were considered
as empirically vacuous (§1). I argue that the prototypical (or ideal) normality of normic laws implies statistical normality
(§2), whence normic laws have empirical content. In §3–4 I explain why reasoning from normic laws is nonmonotonic, and why
the understanding of the individual case is so important here. After sketching some foundations of nonmonotonic reasoning
as developed by AI-researchers (§5), Iargue that normic laws are also the best way to understand ceteris paribus laws (§6).
§7 deals with the difference between physical and non-physical disciplines and §9 with the difference between normicity and
approximation. In §8 it is shown how nonmonotonic reasoning provides a new understanding of the protection of theories against
falsification by auxiliary hypotheses. §10, finally, gives a system- and evolution-theoretical explanation of the deeper reason
for the omnipresence of normic laws in practice and science, and forthe connection between ideal and statistical normality.

Spiritual life is made possible by the evolution of a human neuropsychology that requires social interdependence for its development. Extensive neuroplasticity requires experiential shaping throughout life. The evolution of frontal cortex hypertrophy suggests that much of this shaping is produced by a socially constructed virtual reality, extending beyond immediate experience. Prefrontal colonization makes possible the social scaffolding of neuroregulation, including the emotional attachments necessary for moral life. Cognitive independence from immediate environments enables symbioses with external memory systems, producing novel forms of socially constituted experience and making possible the transformative effect of religious systems upon individual biologies and psychologies. 相似文献

Genetic Influence Helps Explain Variation in Human Fertility: Evidence From Recent Behavioral and Molecular Genetic Studies 总被引:1,自引:0,他引:1

To search for genetic influence on human fertility differentials appears inconsistent with past empirical research and prior interpretations of Fisher's fundamental theorem of natural selection. We discuss Fisher's theorem and give reasons why genetic influences may indeed account for individual differences in human fertility. We review recent empirical studies showing genetic influence on variance in fertility outcomes and precursors to fertility. Further, some of the genetic variance underlying fertility outcomes overlaps with that underlying fertility precursors. Findings from different cultures, different times, different levels of data, and both behavioral and molecular genetic designs lead to the same conclusion: Fertility differentials are genetically influenced, and at least part of the influence derives from behavioral precursors that are under volitional control, which are themselves genetically mediated. 相似文献

采用“间接学习—回忆”实验范式,考查方位记忆的生存优势及生存记忆的性别差异。在电脑屏幕上下左右4个方位随机呈现动物或食物图片,被试相对于中央点对捕获动物或采集食物的难易程度进行评价,然后进行方位回忆测验。实验1和实验2为2(情境:生存情境vs.比赛情境)×2(性别:男vs.女)的被试间设计,发现当狩猎动物或采集食物活动与生存相关时,图片方位回忆的正确率较大;实验3为2(情境:生存狩猎情境vs.生存采集情境)×2(性别:男vs.女)的混合设计,发现不同性别被试在两种生存情境中的图片回忆正确率存在差异。表明方位记忆具有生存优势,生存记忆存在性别差异。 相似文献

Evolutionary theory is becoming an all‐encompassing form of explanation in many branches of philosophy. However, emergence theory uses the concept of self‐organization to support yet alter traditional evolutionary explanation. Biologist Stuart Kauffman suggests that the new science will need to tell stories, not simply as a heuristic device but as part of its fundamental task. This claim is reminiscent of C. S. Peirce's criticism of the doctrine of necessity. Peirce's suggestions reference Hegel, and this essay draws out this Hegelian background, addressing the question of subjectivity and issuing some Hegelian reminders so that such evolutionary and emergent theories will consider the implication of this research program on philosophy of mind. The primary focus is on two post‐Kantian, neo‐Hegelian thinkers in contemporary philosophy who deal with this problem: John McDowell and Robert Brandom. 相似文献

Behavior is a property of living organisms, not of inanimate matter. The problems of physical science are to understand how a phenomenon works; biological science adds the questions of what a phenomenon does and how something that does such things came to be. Exclusive dedication to cause–effect explanations ignores how behavior helps creatures cope with their internal and external environments. Laws of causation describe the precursors to behavior; laws of function describe the effects of behavior. The numerous instances of learning reflect the many ways that selective pressure for altering behavior on the basis of experience has been manifested. Little basis exists for assuming that the various forms of learning reflect either common functions or common processes. Instead, it seems that evolutionary processes have resulted in domain-specific learning. The rules of learning must be understood in terms of the function that the particular manifestation of learning serves for the organism. Evolutionary theory provides the framework for understanding function as well as relations between function and causal mechanisms. 相似文献

Abstract. This essay suggests some future items for an agenda about human viability, defined as survivability with meaning and purpose, by exploring interrelations between nature, humanity, and the work of God. It argues for intrinsic and creative value in nature, so there is a value kinship, as well as a factual kinship, between humans, nature, and God-working. It considers humans as "webs of culture, life, and cosmos" and suggests some implications of this notion of human nature for viability. And it asks what human fulfillment can be in light of the awesome creative-destroying-recreative activity that seems to be the ground of an evolving universe. 相似文献

Abstract. Revolutionary developments in both science and theology are moving the relation between the two far beyond the nineteenth-century “warfare” model. Both scientists and theologians are engaged in a common search for shared understanding. Eight models of interaction are outlined: scientism, scientific imperialism, ecclesiastical authoritarianism, scientific creationism, the two-language theory, hypothetical consonance, ethical overlap, and New Age spirituality. Developments in hypothetical consonance are explored in the work of various scholars, including Ian Barbour, Philip Clayton, Paul Davies, Willem Drees, Langdon Gilkey, Philip Hefner, Nancey Murphy, Wolfhart Pannenberg, Arthur Peacocke, John Polkinghorne, Robert John Russell, Thomas Torrence and Wenzel van Huyssteen. 相似文献

Abstract. I describe the development of my work in relating brain research and religion from my personal roots in my family of origin through my professional responsibilities as a pastor, a clinician, and a theological educator to my developing what I call “a neurotheological approach” to faith and ministry. My early correlations gave simplistic attention to bimodal consciousness as an interpretive tool for understanding religion. Subsequently came a more sophisticated exploration of whole-brain functioning and suggested cultural correlates. Currently, I am explicating tae humanizing brain as reflective of our living in an open system, a universe that is unfolding and evolving, a universe in the hands of the whole-making, integrating, emerging God whose reality far exceeds the insights of cultural construction. As we humans relate to this God, attachment and aspiration are reciprocal. 相似文献
