Abstract. I selectively and critically review the state of knowledge about human evolution and the place of humans vis‐à‐vis living apes, with emphasis on bipedal posture and locomotion, expansion of the brain and associated cognitive capacities, speech, tool behavior, culture, and society. I end with a personal perspective on God and Heaven.  相似文献

ABSTRACT— Animal models have contributed considerably to the current understanding of mechanisms underlying the role of stress in health and disease. Despite the progress made already, much more can be made by more carefully exploiting animals' and humans' shared biology, using ecologically relevant models. This allows a fundamental analysis of factors modulating individual adaptive capacity and hence individual vulnerability to disease. This article highlights an emerging scientific approach that uses a framework of interpretation that is more biologically oriented than previous approaches, to evaluate both the adaptive and maladaptive nature of the stress response in relation to existing environmental demands.  相似文献

人工神经网络是对真实神经元网络的粗略模拟,具有容错性、抗干扰性、高效性等特征,具有学习、记忆等强大的认知功能,因此适宜于心理学许多领域的模拟研究。借助神经网络模型不仅可以模拟和验证以往的实验室研究;还能深入探讨感知、联想、学习和记忆等认知过程的具体发生机理,把握其内在机制;它对探讨内隐记忆、内隐学习等无意识认知过程有极大的启发作用。  相似文献

语义启动是研究语义表征的主要范式。在过去的30年里,通过对语义启动效应的研究,词汇的语义表征理论也从符号联结发展到神经联结,其影响因素也逐步重视多方面的交互作用。究其问题,已有研究还存在很多不一致的结论,对语义内在的表征机制和学习机制缺乏深入了解,对影响语义表征的个体因素考虑不多。  相似文献

Recent controversies surrounding the discernment of design in the natural world are an indication of a pervasive disquiet among believers. Can God as creator/sustainer of creation be reconcilable with the belief that God's work is indiscernible behind secondary evolutionary causes? Christian piety requires that the order experienced in the natural world be evidence of God's love and existence. Theistic evolutionary models rarely examine this matter, assuming that God is indiscernible in the processes and order of the world because only secondary causes can be examined. This leaves antievolutionary perspectives to interpret and address the problem of seeing God in the world. I examine these issues in order to gain more credibility for the religious longing to discern God in nature while at the same time affirming the indubitable truth of an evolutionary history. I argue that God's trinitarian nature, hiddenness, and incarnation give us reason to believe that God's presence in the natural world will be discernible, but only within the natural processes, and thereby only in an obscured fashion. I also argue that newer understandings of evolutionary mechanisms are more consistent with theological appropriation than are strictly Darwinian ones.  相似文献

Using Ecological Momentary Assessment, the within patient associations between drive for thinness, emotional states, momentary urge to be physically active and physical activity were studied in 32 inpatients with an eating disorder. Participants received an electronic device and had to indicate at nine random times a day during 1 week their momentary drive for thinness, positive and negative emotional states and their urge to be physically active and physical activity. Multilevel analyses indicated that patients with higher mean levels for urge to be physically active were characterized by lower body mass index (BMI) and chronically negative affect whereas patients with higher mean levels for physical activity were characterized by lower BMI and higher dispositions for drive for thinness. In addition, within patient relations between drive for thinness and urge to be physically active were moderated by BMI and chronically negative affect whereas within patient relations between drive for thinness and physical activity were moderated by BMI. Finally, also positive emotional states were significantly associated with physical activity within patients. By using a daily process design, characteristics of physical activity were revealed that have not been identified with assessment methods that have a lower time resolution.  相似文献

鉴于人体研究的局限性,动物模型在哮喘研究中起了无可替代的作用。尤其在阐明哮喘的病理生理和免疫学机制方面,动物研究可以给我们提供人体研究难以得到的结果。但是,由于人类与动物之间存在的差别,动物模型的研究结果应用于人类时还需要进一步评估。本文将对哮喘动物模型在哮喘研究中的作用及其局限性作一介绍。  相似文献

While clergy are recognized by their faith communities as important sources of mental health care, questions persist as to the treatment strategies they employ and endorse. This has implication for their likelihood to encourage their members to utilize professional mental health care resources. In this study, a modified version of the treatment portion of the Opinions about Psychological Problems (OPP, Barker, Pistrang & Shapiro, 1983) is used to examine the treatment strategies endorsed by a representative sample of Singaporean clergymen. Besides attempting to show the usefulness of this modified scale, this study highlights that clergy endorse psychological models the most when these models are congruent to their theological belief system. Organic and popular Charismatic deliverance treatment models received less support. Mathew Mathews recently submitted his Ph.D. thesis entitled Clergy & Counsellors: Mental health care in Singapore. He is actively researching issues at the intersection of religion and health including the role of religion in help seeking intentions.  相似文献

A component-functions model of choice behavior is proposed for performance on interdependent concurrent variable-interval (VI) variable-interval schedules based on the product of two component functions, one that enhances behavior and one that reduces behavior. The model is the solution to the symmetrical pair of differential equations describing behavioral changes with respect to two categories of reinforcers: enhancing and reducing, or excitatory and inhibitory. The model describes residence time in interdependent concurrent VI VI schedules constructed from arithmetic and exponential distributions. The model describes the data reported by Alsop and Elliffe (1988) and Elliffe and Alsop (1996) with a variance accounted for of 87% compared to 64% accounted for by the Davison and Hunter (1976) model and 42% by Herrnstein's (1970) hyperbola. The model can explain matching, undermatching, and overmatching in the same subject under different procedures and has the potential to be extended to performance on concurrent schedules with more than two alternatives, multiple schedules, and single schedules. Thus, it can be considered as an alternative to Herrnstein's quantitative law of effect.  相似文献

Almost all admit that there is beauty in the natural world. Many suspect that such beauty is more than an adornment of nature. Few in our contemporary world suggest that this beauty is an empirical principle of the natural world itself and instead relegate beauty to the eye and mind of the beholder. Guided by theological and scientific insight, the authors propose that such exclusion is no longer tenable, at least in the data of modern biology and in our view of the natural world in general. More important, we believe an empirical aesthetics exists that can help guide experimental design and development of computational models in biology. Moreover, because theology and science can both contribute toward and equally profit from such an aesthetics, we propose that this empirical aesthetics provides the foundation for a living synergy between theology and science.  相似文献
