A case of a misplaced conjunction: Nature or nurture?

Some facts are explored about the roles that genes and environments together play in affecting a person's development. The conclusion that our genetic heritage contributes to the complex accounting of variation in our behavior is not pessimistic and does not bode evil for social and educational policy.     

The nature (and nurture) of personality disorders

Personality disorders have a long history in the literature but a short scientific history. The point prevalence of personality disorders is 10%, but the lifetime prevalence is probably 30–40%. Genetic factors contribute to around 40–50% of the variation in the development of personality disorders. The effect of shared environment is very small or non‐existent. Some researchers have tried to promote gene‐environment interaction. However, in reality, the studies investigated gene‐situation interaction, as the “environment” may in reality be partly of a genetic nature. Thus, we are dealing with an unknown part of gene‐gene interaction. Gene‐experience (not gene‐environment) correlations are the rule in human life. Personality disorders co‐occur (are comorbid) with symptom disorders (Axis I) and correlate with common personality dimensions. Possibly, the concept of personality disorder could merge with dysfunctional personality types. But it is likely that the concept will survive on its own.     

The Epic of Evolution: A Course Developmental Project

The Epic of Evolution is a course taught at Northern Arizona University. It engages the task of formulating a new epic myth that is based on the physical, natural, social, and cultural sciences. It aims to serve the need of providing meaning for human living in the vast and complex universe that the sciences now depict for us. It is an interdisciplinary effort in an academic setting that is often divided by specializations; it focuses on values in a climate of relativism; and it concentrates on an enterprise for which there are few textbooks at hand. The course is presented in three segments: the cosmos before humans appeared, the human phenomenon, and scenarios for the future of evolution.     

Nature, nurture, and the development of functional specializations: A computational approach

The roles assigned to nature and nurture in the acquisition of functional specializations have been modified in recent years due to increasing evidence that experience-dependent processes are more influential in determining a brain region’s functional properties than was previously supposed. Consequently, one may study the developmental principles that play a role in the acquisition of functional specializations. This article studies the hypothesis that a combination of structure-function correspondences plus the use of competition between modules leads to functional specializations. This principle has been instantiated in a family of neural network architectures referred to as “mixtures-ofexperts” architectures. These architectures are sensitive to structure-function relationships in the sense that they often learn to allocate to each task a network whose structure is well matched to that task. The viewpoint advocated here represents a middle ground between nativist and constructivist views of modularity.     

The Fascination of Wisdom: Its Nature, Ontogeny, and Function

ABSTRACT— Wisdom has intrigued both scholars and laypersons since antiquity. On the one hand, its seemingly ethereal yet obvious qualities are timeless and universal. On the other hand, these same qualities are evolving and responsive to historical and cultural change. Novel societal and personal dilemmas emerge over time, and the ways and means to deal with recurring dilemmas are revisited and updated with prudence. Building on philosophical analyses of the role of theoretical and practical wisdom in good conduct and judgment about life matters, psychologists have begun to apply scientific methods to questions about the nature, function, and ontogeny of wisdom. We outline these research directions and focus on the Berlin Wisdom Paradigm, which was one of the first attempts to bring wisdom into the laboratory. Future research on wisdom would profit from interdisciplinary collaboration and creative application of new methods drawn from developmental, social, and cognitive psychology.     

The Episodic Nature of Experience: A Dynamical Systems Analysis

Context is an important construct in many domains of cognition, including learning, memory, and emotion. We used dynamical systems methods to demonstrate the episodic nature of experience by showing a natural separation between the scales over which within‐context and between‐context relationships operate. To do this, we represented an individual's emails extending over about 5 years in a high‐dimensional semantic space and computed the dimensionalities of the subspaces occupied by these emails. Personal discourse has a two‐scaled geometry with smaller within‐context dimensionalities than between‐context dimensionalities. Prior studies have shown that reading experience (Doxas, Dennis, & Oliver, 2010) and visual experience (Sreekumar, Dennis, Doxas, Zhuang, & Belkin, 2014) have a similar two‐scaled structure. Furthermore, the recurrence plot of the emails revealed that experience is predictable and hierarchical, supporting the constructs of some influential theories of memory. The results demonstrate that experience is not scale‐free and provide an important target for accounts of how experience shapes cognition.     

动物和人类的利他本性:共情的进化

共情指个体感知或想象其他个体的情感,并部分体验到其他个体感受的心理过程.利他指以增加其他个体的福利为最终目标的动机.共情起源于动物的亲代养育行为,其神经基础来源于古老的情感系统.共情从动物低水平的情绪感染逐渐进化到同情关注以及观点采择共情.另外,共情具有良好的环境适应性.未来可以进一步研究动物与人类的共情和利他行为的异同,加大研究动物的高级共情能力和利他行为以及深入研究共情受社会因素的调节机制.     

E = f(P,B): The road to a radical approach to person-environment fit

The title suggests the thesis of this article: Environments are a function of the people behaving in them. I first briefly review my personal saga resulting in the idea that persons cause environments to be what they are. Then I review a new conceptualization of organizational functioning based on the attraction-selection-attrition framework. Implications of this framework for various areas of study in I/O psychology and vocational behavior are then described.     

人性与法域的断想

人性的完善是导致法域变迁的内在动因,法从起源到发展都莫不与人性密切相关,任何法域及域内之法都不过是人类本性的某些表现.以人性的拓展为研究脉络,人类法制演进的历程跃然凸现.从公私法域的分化到社会法域的衍生甚至生态法域的出现,人性在无形中推动着人类法制发展的全部过程.法在当代的多样化发展趋势.乃是人性多方面展开的必然结果.     

The Evolution of Consciousness and the Theology of Nature

Theology and philosophy have traditionally assumed a radical split between human beings and the rest of creation. Philosophically, the split is usually justified in terms of a locus humanus , some one cognitive trait that human beings possess and nonhuman animals do not. Theologically, this trait is usually identified as that which makes us in the image of God. Research in animal cognition, however, suggests that we are not unique in as many respects as we think we are. This suggests that we rethink the idea of the image of God. In light of this, I propose that we think of nature itself as being in the image of God, with humankind as part of the broader natural and theological process.     

Nature,nurture and academic achievement: A twin study of teacher assessments of 7‐year‐olds

Background: Twin research has consistently shown substantial genetic influence on individual differences in cognitive ability; however, much less is known about the genetic and environmental aetiologies of school achievement. Aims: Our goal is to test the hypotheses that teacher‐assessed achievement in the early school years shows substantial genetic influence but only modest shared environmental influence when children are assessed by the same teachers and by different teachers. Sample: 1,189 monozygotic (MZ) and dizygotic (DZ) twin pairs born in 1994in England and Wales. Methods: Teachers evaluated academic achievement for 7‐year‐olds in Mathematics and English. Results were based on the twin method, which compares the similarity between identical and fraternal twins. Results: Suggested substantial genetic influence in that identical twins were almost twice as similar as fraternal twins when compared on teacher assessments for Mathematics, English and a total score. Conclusions: The results confirm prior research suggesting that teacher assessments of academic achievement are substantially influenced by genetics. This finding holds even when twins are assessed independently by different teachers.     

The nature and nurture of expertise: a fourth dimension

One formative idea behind the workshop on expertise in Berkeley in August of 2010 was to develop a viable “trading zone” of ideas, which is defined as a location “in which communities with a deep problem of communication manage to communicate” (Collins et al. 2010, p. 8). In the current case, the goal is to have a trading zone between philosophers, sociologists, and psychologists who communicate their ideas on expertise such that productive interdisciplinary collaboration results. In this paper, I review Harry Collins' three-dimensional model of expertise and provide a very brief and non-inclusive overview of a psychological response. In addition, I propose an addendum to the model by adding a fourth—natural talent—dimension.     

The Nature and Significance of Behavioural Genetic Information

In light of the human genome project, establishing the genetic aetiology of complex human diseases has become a research priority within Western medicine. However, in addition to the identification of disease genes, numerous research projects are also being undertaken to identify genes contributing to the development of human behavioural characteristics, such as cognitive ability and criminal tendency. The permissibility of this research is obviously controversial: will society benefit from this research, or will it adversely affect our conceptions of ourselves and each other? When assessing the permissibility of this research, it is important to consider the nature and deterministic significance of behavioural genetic information. Whilst todate there has been much discussion and debate about the properties of genetic information per se and genetic determinism, this has not been applied to behavioural genetic research and its ethical implications. Therefore, this paper elucidates how behavioural genetic information can be distinguished from other types of genetic and non-genetic information and also synthesises the determinative significance of genetic factors for the development of human behavioural traits. Undertaking this analysis enables the ethical issues raised by this research to be debated in an appropriate context and indicates that separate policy considerations are warranted.

     

The Developmental Leadership Questionnaire (DLQ): some psychometric properties

The development leadership model (Larsson et al., 2003), designed to introduce refinements to the transformational leadership model, has been adopted for use in the Swedish Armed Forces. The Developmental Leadership Questionnaire (DLQ) was constructed to measure important parts of the model. The main aim of the study was to evaluate some psychometric properties of the DLQ. Most analyses are based on two subsets of individuals from a sample mostly consisting of male Swedish, military officers, each of whom has rated a given leader (n = 450 and 449 respectively). A second sample consisted of Swedish military cadets (n = 141). The dimensionality was assessed with a confirmatory factor analysis. Most DLQ scales were reasonably well reproduced and showed high or acceptable internal consistency. When related to perceived results of leadership (self-rated by leaders and rated by subordinates), results from multiple regression analyses supported what could be predicted by the theoretical model. It was concluded that the DLQ has acceptable psychometric properties and that the theoretical refinements introduced to the developmental leadership model were empirically supported.     

The Productive Power of Ambiguity: Rethinking Homosexuality through the Virtual and Developmental Systems Theory

This paper juxtaposes Deleuze's notion of the virtual alongside Oyama's notion of a developmental system in order to explore the promises and perils of thinking bodily identity as indeterminate at a time when new technologies render bodily ambiguity increasingly productive of both economic profit and power relations.     

The Dynamics of General Developmental Mechanisms: From Piaget and Vygotsky to Dynamic Systems Models

Dynamic systems theory conceives of development as a self-organizational process. Both complexity and order emerge as a product of elementary principles of interaction between components involved in the developmental process. This article presents a dynamic systems model based on a general dual developmental mechanism, adapted from Piaget and Vygotsky. The mechanism consists of a conservative force, further strengthening the already-consolidated level, and a progressive force, consolidating internal contents and procedures at more advanced levels. It is argued that this dual mechanism constitutes one of the few basic laws of learning and change, and is comparable to the laws of effect and of contiguity. Simulation studies suggest that this dual mechanism explains self-organization in developmental paths, including the emergence of discrete jumps from one equilibrium level to another, S-shaped growth, and the occurrence of co-existing levels.
