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.     

进化观点下的幸福研究

人类社会生活的一项重要目标是追求幸福(happiness), 影响幸福体验的因素有食物、财富、婚姻及友谊等。寻求幸福与避免痛苦能让人们的幸福需求得到满足。幸福和痛苦不是人类通过进化获得的一种最终机能, 然而幸福和痛苦对人类远古祖先的影响在于调节行为活动以增加生存与繁衍可能。为什么有些环境刺激比其他刺激更能让人体验幸福？为什么回避痛苦与追求幸福同样重要？为什么幸福体验有相对性、过度性与目标性的特点？这些问题可以在进化观点中得到较好回答。人们的幸福感可以在认识基因与环境关系的基础上得到加强, 如加强亲属联系、强化社会合作、重视婚姻承诺以及满足本能欲望等。     

进化心理学视角下的智力研究

进化心理学和差异心理学是心理学的两个分支。进化心理学认为智力是一种进化的适应。差异心理学中智力是个体差异变量。本文试图整合二者的观点。认为智力既是进化的适应,也是个体差异变量。这将启示进化心理学家去研究更广范围的心理特质,允许智力研究和差异心理学运用进化心理学的理论和概念。本文还介绍了与智力进化相关的热带草原法则和Kanazawa的Savanna—IQ互动假说。     

Human Nature and Culture: An Evolutionary Psychological Perspective

Personality psychology is the broadest of all psychological subdisciplines in that it seeks a conceptually integrated understanding of both human nature and important individual differences. Cultural differences pose a unique set of problems for any comprehensive theory of personality—how can they be reconciled with universals of human nature on the one hand and within‐cultural variation on the other? Evolutionary psychology provides one set of conceptual tools by which this conceptual integration can be made. It requires jettisoning the false but still‐pervasive dichotomy of culture versus biology, acknowledging a universal human nature, and recognizing that the human mind contains many complex psychological mechanisms that are selectively activated, depending on cultural contexts. Culture rests on a foundation of evolved psychological mechanisms and cannot be understood without those mechanisms.     

Acculturation and Psychological Adjustment of Vietnamese Refugees: An Ecological Acculturation Framework

Acculturation to the culture of the host society as well as to one’s heritage culture have been shown to impact immigrants’ adjustment during the years following resettlement. While acculturation has been identified as an important factor in adjustment of Vietnamese immigrants (Birman and Tran in Am J Orthopsychiatr 78(1):109–120. doi:10.1037/0002‐9432.78.1.109, 2008 ), no clear pattern of findings has emerged and too few studies have employed an ecological approach. The purpose of this paper is to contextualize the study of acculturation and adjustment by taking an ecological approach to exploring these relationships across several life domains, using a bilinear scale, and examining mediators of these relationships for adult Vietnamese refugees (N = 203) in the United States. We call this approach the Ecological Acculturation Framework (EAF). Results of a structural equation model (SEM) showed that job satisfaction fully mediated the relationship between American acculturation and psychological distress, demonstrating that this relationship was specific to an occupational domain. However, while Vietnamese acculturation predicted co‐ethnic social support satisfaction, it did not predict reduced psychological distress. Implications for a life domains approach, including domain specificity, are discussed.     

A Systematic Framework for Integrating Psychological Evaluations and Interventions

A systematic framework for an integrative approach to psychological evaluations and interventions is proposed based on the executive system model of intelligence, the transactional processes of stress and coping, and the field properties of the personal domain. The executive system of intelligence is a comprehensive model that helps to explain the active components of various types of psychotherapies. We are proposing that psychotherapies facilitate clients' uses of their executive functions to develop coping strategies in their transactions with the environment and the events in their life space. A clinical case is presented to illustrate our systematic approach to psychological evaluation and intervention.     

Multilevel Selection Theory and Major Evolutionary Transitions: Implications for Psychological Science

ABSTRACT— The concept of a group as comparable to a single organism has had a long and turbulent history. Currently, methodological individualism dominates in many areas of psychology and evolution, but natural selection is now known to operate at multiple levels of the biological hierarchy. When between-group selection dominates within-group selection, a major evolutionary transition occurs and the group becomes a new, higher-level organism. It is likely that human evolution represents a major transition, and this has wide-ranging implications for the psychological study of group behavior, cognition, and culture.     

An Alternative Framework for Defining Mediation

The present article provides an alternative framework for evaluating mediated relationships. From this perspective. a mediated process is a chain reaction, beginning with an independent variable that affects a mediator that in turn affects an outcome. The definition of mediation offered here, presented for stage sequences, states three conditions for establishing mediation: (a) the independent variable affects the probability of the sequence no mediator to mediator to outcome; (b) the independent variable affects the probability of a transition into the mediator stage; (c) the mediator affects the probability of a transition into the outcome stage at every level of the independent variable. This definition of mediation is compared and contrasted with the well-known definition of mediation for continuous variables discussed in Baron and Kenny (1986), Judd and Kenny (1981), and Kenny, Kashy, and Bolger (1997). The definition presented in this article emphasizes the intraindividual, time-ordered nature of mediation.

An Ethical Framework for Evaluating Experimental Technology

How are we to appraise new technological developments that may bring revolutionary social changes? Currently this is often done by trying to predict or anticipate social consequences and to use these as a basis for moral and regulatory appraisal. Such an approach can, however, not deal with the uncertainties and unknowns that are inherent in social changes induced by technological development. An alternative approach is proposed that conceives of the introduction of new technologies into society as a social experiment. An ethical framework for the acceptability of such experiments is developed based on the bioethical principles for experiments with human subjects: non-maleficence, beneficence, respect for autonomy, and justice. This provides a handle for the moral and regulatory assessment of new technologies and their impact on society.

Morality: An Evolutionary Account

ABSTRACT— Refinements in Darwin's theory of the origin of a moral sense create a framework equipped to organize and integrate contemporary theory and research on morality. Morality originated in deferential, cooperative, and altruistic "social instincts," or decision-making strategies, that enabled early humans to maximize their gains from social living and resolve their conflicts of interest in adaptive ways. Moral judgments, moral norms, and conscience originated from strategic interactions among members of groups who experienced confluences and conflicts of interest. Moral argumentation buttressed by moral reasoning is equipped to generate universal and impartial moral standards. Moral beliefs and standards are products of automatic and controlled information-processing and decision-making mechanisms. To understand how people make moral decisions, we must understand how early evolved mechanisms in the old brain and recently evolved mechanisms in the new brain are activated and how they interact. Understanding what a sense of morality is for helps us understand what it is.     

An Historical Framework for Cohort Differences in Intelligence

This article reviews key issues regarding the controversy on the direction and magnitude of cohort differences in intelligence. Data from the Seattle Longitudinal Study (SLS) illustrate why differences must be studied across multiple cohorts and multiple chronological ages. Differential cohort patterns for multiple dimensions of intelligence are described. A conceptual framework is suggested for the identification of historical influences important for developmental study of cohort differences.     

Schizotypy: An Organizing Framework for Schizophrenia Research

ABSTRACT— Schizophrenia is the most devastating form of psychopathology known to humankind, and it has been slow to yield clues to its origins. Meehl's (1962, 1990) model detailed the nature of the latent liability for schizophrenia known as schizotypy and provided a major organizing function for research on schizophrenia. The schizotypy model integrates genetic and environmental contributions to liability as well as accounting for a range of clinical outcomes, all deriving from a genuine liability for the illness. Schizotypy, as a latent personality organization that harbors the liability for schizophrenia, provides a framework for detecting fundamental features of liability to schizophrenia prior to the onset of clinical illness. The schizotypy model is reviewed, the strategic benefits of it are discussed, and methods for detecting schizotypy are presented. A focus on perceptual aberrations—a schizotypic feature—in individuals unaffected by schizophrenia has yielded valuable clues to preclinical disturbances in neurocognitive processes, risk for schizophrenia among biological relatives, and genomic substrates, all of which are of interest to schizophrenia researchers.
