An Evolutionary Life History Framework for Psychopathology

In this article, I outline a general framework for the evolutionary analysis of mental disorders based on the concepts of life history theory. I synthesize and extend a large body of work showing that individual differences in life history strategy set the stage for the development of psychopathology. My analysis centers on the novel distinction between fast spectrum and slow spectrum disorders. I describe four main causal pathways from life history strategies to psychopathology, argue that psychopathology can arise at both ends of the fast–slow continuum of life history variation, and provide heuristic criteria for classifying disorders as fast or slow spectrum pathologies. I then apply the fast–slow distinction to a diverse sample of common mental disorders: externalizing disorders, schizophrenia and autism spectrum disorders, obsessive-compulsive disorders, eating disorders, and depression. The framework integrates previously disconnected models of psychopathology within a common frame of reference and has far-reaching implications for the classification of mental disorders.     

Toward an Evolutionary History of Female Sociosexual Variation

ABSTRACT Considerable progress has been made in behavioral genetics toward providing theoretical accounts of individual differences One theoretical task, however, has been largely neglected—that of constructing evolutionary accounts of behaviorally relevant genetic variance We attempt to address this task with respect to the genetic variance underlying sociosexuality, that is, the differences in the implicit prerequisites (in terms of time, attachment, commitment, etc) to entering a sexual relationship Specifically, we argue that genetic variance on this trait for females could have been maintained through frequency-dependent selection In our evolutionary past, restricted females-those who require relatively more time, attachment, and commitment-could have benefited through paternal investment in their offspring Unrestricted females—those who require relatively less time, attachment, and commitment—could have benefited through the quality of their mate's genes passed on to their sons Moreover, the value of these alternate „strategies” could have been frequency-dependent One prediction that follows from this evolutionary history is tested and supported in three studies Those females genetically predisposed to be unrestricted are found to produce relatively more sons than females predisposed to be restricted Additional predictions are offered and alternative accounts are discussed     

The Evolutionary Challenge for Technology

The evolutionary challenge for technology in the third millennium is one of designing the vehicles for sustainable human and societal development in partnership with earth. The challenge calls for the conscious creation of evolutionary systems-not through the "hard technologies" that shape and mold the physical infrastructure of our planet, but through "soft technologies" that augment creative and constructive processes of human interaction. Through them, humanity has the opportunity to create the conditions for the emergence of a true learning society at both regional and global levels. The meaning of key terms such as evolution, technology, and development must be explored if we are to create a shared understanding of the contemporary survival challenges faced by humanity. This paper explores both the promise and the threat faced by a techno-civilization such as is emerging on our planet in the early twenty-first century.     

The Necklace of Numbers

The necklace of numbers is a symbol that came in one of my dreams at the end of 2006, at the time when I was about to leave France, my native country, and come to the United States. As I was going through the process of becoming an American citizen, I felt compelled to reconnect to my French roots. The result was this personal account which tells the most important dreams that led me to this country. It is also a tale of a mid-life transformation, a tale of an immigrant viewed from inside, and a tale of individuation by following the path of love.     

生命史理论：进化视角下的生命发展观

传统的心理学研究很少从发展角度系统地考察童年早期经历和个体生物性发展之间的关系。然而，以进化理论为基础的生命史理论的研究表明，个体的幼年环境会影响一系列生命史事件的出现和持续时间。其要义在于，为了最大限度地成功繁衍，个体会根据环境线索来做出关乎生存和繁衍的具有适应性的权衡。特别地，性成熟时间是生命史理论区别于其他人类发展理论的核心变量。未来的研究一方面需要深入挖掘人类社会规范在生命史权衡中的意义，另一方面还要继续探索实证研究的新方法。     

The New Problem of Numbers in Morality

Discussion of the “problem of numbers” in morality has focused almost exclusively on the moral significance of numbers in whom-to-rescue cases: when you can save either of two groups of people, but not both, does the number of people in each group matter morally? I suggest that insufficient attention has been paid to the moral significance of numbers in other types of case. According to common-sense morality, numbers make a difference in cases, like the famous Trolley Case, where we must choose whether to kill a person (or persons) as a side effect of saving a greater number. I argue that recognition of the role of numbers in killing cases forces us to reassess purported solutions to the problem of numbers.     

一位阿拉伯数字的空间表征

数字数量的空间表征问题是认知心理学领域的研究热点之一。本研究采用Fischer等人的实验范式,探讨了较浅程度加工时一位阿拉伯数字在水平和垂直方向上的空间表征,结果发现:(1)对数字进行较浅程度的加工(仅仅注视数字)时,在水平方向上出现了SNARC效应,即激活了数字在水平方向上的空间表征,数字数量按照小、中、大的顺序自左而右地映射到心理数字线上;(2)对数字进行较浅程度加工时,在垂直方向上没有出现SNARC效应,即未激活数字在垂直方向上的空间表征。     

疾病的进化论解释：——读《我们为什么生病》

现代医学重在对疾病的近因研究,而疾病的进化史原因,像机体设计上的缺陷,遗传基因与新环境因素的冲突,进化过程中病原同宿主的竞争等,却几乎完全被忽视。事实上,人类机体在漫长的进化过程中,每获得一种益处,几乎都要付出相应的代价,这就是相关的疾病。达尔文医学的新科学,这部全新视野的著作,全面地向人们展示了疾病的进化论解释,并正在创造其学术范式迥然不同的医学科学新领域。     

The Causal Structure of Evolutionary Theory

One contentious debate in the philosophy of biology is that between the statisticalists and causalists. The former understand core evolutionary concepts like fitness and selection to be mere statistical summaries of underlying causal processes. In this view, evolutionary changes cannot be causally explained by selection or fitness. The causalist side, on the other hand, holds that populations can change in response to selection—one can cite fitness differences or driftability in causal explanations of evolutionary change. But, on the causalist side, it is often not clear how, precisely, one should understand these causes. Thus, much more could be said about what sort of causes fitness and driftability are. In this paper, I borrow Dretske's distinction between structuring and triggering causes and I suggest that fitness and driftability are structuring causes of evolution.     

The Epistemic Status of Evolutionary Theory

The theory of evolution continues to be a bone of contention among certain groups of theistic believers. This paper aims to bring some light to the debate about it, by introducing a framework for epistemic appraisal which can provide a realistic and sober assessment of the epistemic credentials of the various parts of evolutionary theory. The upshot is a more nuanced epistemic appraisal of the theory of evolution, which shows that there are significant differences in epistemic standing between its various parts. Any serious conversation about the theory of evolution ought to reflect these facts.     

Making Numbers Come to Life: Two Scoring Methods for Creativity in Aurora's Cartoon Numbers

Although creativity has long been recognized as an important aspect of mathematical thinking, both for the advancement of the field and in students' developing expertise in mathematics, assessments of student creativity in that domain have been limited in number and focus. This article presents an assessment developed for creativity that provides a score for mathematical creativity (MaC) in addition to a score for general creativity in the numeric domain, or what we might call numerical creativity (NuC). We developed different rating scales for each and then explored how each scoring method accounts for the students' mathematical/numerical and creative skills. The psychometric properties for both scoring approaches were examined. Each method was shown to reflect different relationships with other performance tests. In addition, it is proposed that MaC may provide useful insight into students' levels of adaptive expertise in mathematics, as reflected by their ability to apply mathematical knowledge (i.e., language, operations, concepts) to novel situations, representing an informative supplement to performance indicators of math achievement.
