Why is risk consistently underestimated, and why do young men in particular take exceptionally high risks and think of themselves as invulnerable? Two explanatory paths are proposed. The first is that risk taking in young males has been shaped by evolutionary forces to provide a fitness value. The second pathway is through myth and the other narrative forms that affirm the ego's immortality and invulnerability. Because of its evolutionary base, risk taking is emotionally driven: Emotions are preverbal and irrational, which means that persuasive prevention cannot be more than weakly successful. Three prevention challenges emerge from this analysis: to determine what it is that young drivers fear, to attach affectively experienced fears to defined driving behaviors, and to devise injury-prevention programs that acknowledge that young males' risk taking is not "stupid," but driven by adaptive needs that are as significant to today's young adults as they were to our distant ancestors. 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.

The purpose of this study is to discuss the dynamic interdependence of knowledge and economic growth. We show that the traditional economics, which treats knowledge as parameters and is mainly developed within linearized, stable and static frameworks can hardly explain the modern economic complexity. We argue that it is necessary to treat creativity, learning and knowledge utilization as endogenous dynamic processes of social and economic evolution. To handle with the complicated dynamic interdependence of wealth and knowledge accumulation, we need to apply genuine nonlinear dynamic theory. In particular, we discuss possible benefits of government's intervention in education and science to the society when the social and economic evolution is characterized of nonlinearity, instability and multi‐equilibria. 相似文献

Although children with language impairments, including those associated with reading, usually demonstrate deficits in phonological processing, there is minimal agreement as to the source of those deficits. This study examined two problems hypothesized to be possible sources: either poor auditory sensitivity to speech-relevant acoustic properties, mainly formant transitions, or enhanced masking of those properties. Adults and 8-year-olds with and without phonological processing deficits (PPD) participated. Children with PPD demonstrated weaker abilities than children with typical language development (TLD) in reading, sentence recall, and phonological awareness. Dependent measures were word recognition, discrimination of spectral glides, and phonetic judgments based on spectral and temporal cues. All tasks were conducted in quiet and in noise. Children with PPD showed neither poorer auditory sensitivity nor greater masking than adults and children with TLD, but they did demonstrate an unanticipated deficit in category formation for nonspeech sounds. These results suggest that these children may have an underlying deficit in perceptually organizing sensory information to form coherent categories. 相似文献

In this paper, a Jungian understanding of cultural factors influencing individual analysis is illustrated with the case of a patient suffering from panic attacks. The analysis revealed that, in addition to the patient's personal background, the collectivistic attitudes of the Soviet culture, which had a moulding effect on the patient in his childhood and obstructed his individuation, should be taken into account. The concepts of the totalitarian object and the Russian cultural complex encompassing a grandiosity pole and an inferiority pole are used to explore the patient's condition, and the crucial role of creating mutual language with the patient is outlined. 相似文献

This article is an analysis and critique of emergent theologies, focusing on areas of Christology and pneumatology. An increasing number of Christian theologians are integrating (strong) emergence theory into their work. I argue that, despite the range of theological commitments and methodological approaches represented by these scholars, each faces similar problematic tendencies when their Christian doctrines are combined with (strong) emergence theory. It is concluded that the basic logic of emergence theory, whereby matter is seen to precede mind, makes it difficult for emergent theologies to offer an account of salvation, avoid significant issues regarding God's involvement with evil, and maintain divine transcendence. It is concluded, therefore, that Christian theology should look elsewhere for a complementary metaphysical framework with which to bridge scientific and theological discourse. 相似文献

What Causes Specific Language Impairment in Children? 总被引:2,自引:0,他引:2

ABSTRACT— Specific language impairment (SLI) is diagnosed when a child's language development is deficient for no obvious reason. For many years, there was a tendency to assume that SLI was caused by factors such as poor parenting, subtle brain damage around the time of birth, or transient hearing loss. Subsequently it became clear that these factors were far less important than genes in determining risk for SLI. A quest to find "the gene for SLI" was undertaken, but it soon became apparent that no single cause could account for all cases. Furthermore, although fascinating cases of SLI caused by a single mutation have been discovered, in most children the disorder has a more complex basis, with several genetic and environmental risk factors interacting. The clearest evidence for genetic effects has come from studies that diagnosed SLI using theoretically motivated measures of underlying cognitive deficits rather than conventional clinical criteria. 相似文献

Three students with moderate handicaps were taught to initiate and expand on conversational topics. The teaching procedure used stimuli generated from actual conversations with nonhandicapped peers. Generalization was assessed by audiotaping conversations between the handicapped students and their peers in natural school contexts without adult supervision. Results indicated that training generalized to natural contexts. These results were socially validated by undergraduate special education students, who rated tapes of two of the students' conversations during training phases as more socially competent than during baseline. Results are discussed in terms of the evaluation of complex social behavior as multioperant behaviors. 相似文献
