Modern application of evolutionary theory to psychology: key concepts and clarifications

Darwinian selection has become the centerpiece of biology, and in the past few decades many psychologists and anthropologists have recognized the value of using an evolutionary perspective to guide their work. With a focus on evolved psychological mechanisms and associated information processing features, evolutionary psychology has risen as a compelling and fruitful approach to the study of human psychology and behavior. In this article we review the instrument of evolution: natural selection, the products of evolution, and the impact of evolutionary thinking on modern psychological science. We conclude that as prejudicial barriers are overcome, as more evolutionary psychological work is conducted, and as hypothesized psychological mechanisms are substantiated in other disciplines, evolutionary psychology will emerge as the metatheory for psychology.     

The new history of psychology: a review and critique

In the past 30 years, the "new history of psychology" and its adherents have advocated a critical approach to scholarship, increased use of primary sources, a focus on sociopolitical forces, and the active inclusion of psychologists from underrepresented groups. This article argues that many scholars exaggerate the differences between old and new history of psychology, and that where the differences are indeed large, those discrepancies reveal certain limitations unique to the new history approach. These limitations, presented in the form of 5 questions posed to new historians, lead to a discussion of professional issues in the history of psychology.     

Toward an alternative evolutionary theory of religion: looking past computational evolutionary psychology to a wider field of possibilities

Cognitive science of the last half-century has been dominated by the computational theory of mind and its picture of thought as information processing. Taking this picture for granted, the most prominent evolutionary theories of religion of the last fifteen years have sought to understand human religiosity as the product or by-product of universal information processing mechanisms that were adaptive in our ancestral environment. The rigidity of such explanations is at odds with the highly context-sensitive nature of historical studies of religion, and thus contributes to the apparent tug-of-war between scientific and humanistic perspectives. This essay argues that this antagonism stems in part from a deep flaw of computational theory, namely its notion of information as pre-given and context-free. In contrast, non-computational theories that picture mind as an adaptive, interactive process in which information is jointly constructed by organism and environment offer an alternative approach to an evolutionary understanding of human religiosity, one that is compatible with historical studies and amenable to a wide range of inquiries, including some limited kinds of theological inquiry.     

Bridging developmental systems theory and evolutionary psychology using dynamic optimization

Interactions between evolutionary psychologists and developmental systems theorists have been largely antagonistic. This is unfortunate because potential synergies between the two approaches remain unexplored. This article presents a method that may help to bridge the divide, and that has proven fruitful in biology: dynamic optimization. Dynamic optimization integrates developmental systems theorists’ focus on dynamics and contingency with the ‘design stance’ of evolutionary psychology. It provides a theoretical framework as well as a set of tools for exploring the properties of developmental systems that natural selection might favor, given particular evolutionary ecologies. We also discuss limitations of the approach.     

The subject of psychology: A Lacanian critique

This paper provides an overview of Jacques Lacan's views on psychology, paying particular attention to how such critiques support a distinctively Lacanian view of the subject. Lacan attacked various facets of psychology, including: psychology's objectifying (and objectivistic) tendencies; the discipline's historical attempt to model itself on the natural sciences; its conceptual and practical prioritizations of the ego and consciousness; its frequent prioritization of developmental, biological and physiological paradigms above a careful analysis of the structures and operations of language and speech. The aim of the paper is not to systematically work through Lacan's various criticisms, still less to refute them. Ultimately, Lacan's historical attacks against psychology—apposite as they are—have their greatest value in helping us to strike some distance from commonplace assumptions and psychological assumptions about the nature of the subject.     

Evolutionary psychology and consumer behavior: A constructive critique

We examine the theoretical basis for the evolutionary narrative common to the target papers by Saad (this issue) and by Griskevicius and Kenrick (this issue) and identify areas of controversy that have sparked debate about evolutionary psychology [EP] among biologists and behavioral ecologists. The two main areas of disagreement are over (1) the role of genetic adaptations resulting from natural selection in ancient times compared to other forces leading to current behavior; and (2) the likelihood that evolution resulted in a set of highly specialized mental modules or information-processing circuits thought to be instrumental in determining present-day behavior. We review the EP research discussed by the authors of the target papers as a means of evaluating the evidence in support of the theory and of suggesting future directions of research.     

Developmental dynamics: toward a biologically plausible evolutionary psychology

There has been a conceptual revolution in the biological sciences over the past several decades. Evidence from genetics, embryology, and developmental biology has converged to offer a more epigenetic, contingent, and dynamic view of how organisms develop. Despite these advances, arguments for the heuristic value of a gene-centered, predeterministic approach to the study of human behavior and development have become increasingly evident in the psychological sciences during this time. In this article, the authors review recent advances in genetics, embryology, and developmental biology that have transformed contemporary developmental and evolutionary theory and explore how these advances challenge gene-centered explanations of human behavior that ignore the complex, highly coordinated system of regulatory dynamics involved in development and evolution.     

The motor theory of social cognition: a critique

Recent advances in the cognitive neuroscience of action have considerably enlarged our understanding of human motor cognition. In particular, the activity of the mirror system, first discovered in the brain of non-human primates, provides an observer with the understanding of a perceived action by means of the motor simulation of the agent's observed movements. This discovery has raised the prospects of a motor theory of social cognition. In humans, social cognition includes the ability to mindread, and many motor theorists of social cognition try to bridge the gap between motor cognition and mindreading by endorsing a simulation account of mindreading. Here, we question the motor theory of social cognition and give reasons for our skepticism.     

Group psychology and the structural theory: a revised psychoanalytic model of group psychology.

It has been my aim in this paper to revise the existing psychoanalytic theory of group psychology in accordance with current structural concepts. The need for fundamental revision in the existing theory of group organization is demonstrated by its restriction to an oedipal paradigm, which cannot account for the regression to an oral paradigm of group organization during group formation. Freud's explanation of regression in crowds is reviewed. The limitations inherent in Freud's topographic and narcisistic models are demonstrated; irreconcilable contradictions are shown to exist between the two theories. A structural model of group psychology that is free from internal contradictions and provides a unifying explanation for both regression and merging in the crowd is developed. As a consequence of these revisions it is possible to conceptualize preoedipal organizations of group structure in addition to the oedipal paradigm proposed by Freud.     

Empirically based psychology of Islam: summary and critique of the literature

In this paper, we systematically review the growing empirically based psychology of Islam. We arrive at 10 conclusions: (l) Islam is a multidimensional religion; Islam might mean different things to different people, and some people might adhere to some of its elements but not to others; (2) Islam is similar to, but is different from, other religions; (3) Islam's role in the lives of Muslims seems mostly positive; (4) Some types of Islamic religiousness are negative; (5) The empirical findings have not been translated yet into clinical applications; (6) Most of studies conducted among Muslims provide only a birds-eye view of Islam; (7) Empirical studies of Muslims are scarce; (8) Empirical research on negative types of religiousness among Muslims is sparse; (9) The majority of research in this field has been restricted to convenient samples; (10) Several important topics with implications for Muslims deserve further consideration, and there is a need for more varied research methods in studies of Muslims. The implications of these findings and the limitations of this review are discussed.     

The growth of developmental thought: Implications for a new evolutionary psychology

Evolution has come to be increasingly discussed in terms of changes in developmental processes rather than simply in terms of changes in gene frequencies. This shift is based in large part on the recognition that since all phenotypic traits arise during ontogeny as products of individual development, a primary basis for evolutionary change must be variations in the patterns and processes of development. Further, the products of development are epigenetic, not just genetic, and this is the case even when considering the evolutionary process. These insights have led investigators to reconsider the established notion of genes as the primary cause of development, opening the door to research programs focused on identifying how genetic and non-genetic factors coact to guide and constrain the process of development and its outcomes. I explore this growth of developmental thought and its implications for the achievement of a unified theory of heredity, development, and evolution and consider its implications for the realization of a new, developmentally based evolutionary psychology.     

Rape,money, and the psychology of taboo

Policy and legal decision making sometimes requires difficult assessments about how to translate the harm of sexual assault into dollar amounts. A web‐based experiment (n = 743) was designed to test the psychology of taboo theory in this important context. The experiment included two unique features. First, subjects were randomly assigned to assess vignettes in either a dollar metric, a 7‐point harm scale metric, or a years‐in‐jail metric. Second, subjects were given the opportunity, but not required, to provide a comment when making their assessment. Assignment to the dollar metric treatment group resulted in subjects freely expressing significantly more constitutive incommensurability comments. The effect was most pronounced when the level of sexual assault in the vignette was greatest.     

Comparative evolutionary psychology of sperm competition

A comparative evolutionary psychological perspective predicts that species that recurrently faced similar adaptive problems may have evolved similar psychological mechanisms to solve these problems. Sperm competition provides an arena in which to assess the heuristic value of such a comparative evolutionary perspective. The sperm competition that results from female infidelity and polyandry presents a similar class of adaptive problems for individuals across many species. The authors first describe mechanisms of sperm competition in insects and in birds. They suggest that the adaptive problems and evolved solutions in these species provide insight into human anatomy, physiology, psychology, and behavior. The authors then review recent theoretical and empirical arguments for the existence of sperm competition in humans and discuss proposed adaptations in humans that have analogs in insects or birds. The authors conclude by highlighting the heuristic value of a comparative evolutionary psychological approach in this field.
