The Adapted mind : evolutionary psychology and the generation of culture

Abstract: Although researchers have long been aware that the species-typical architecture of the human mind is the product of our evolutionary history, it has only been in the last three decades that advances in such fields as evolutionary biology, cognitive psychology, and paleoanthropology have made the fact of our evolution illuminating. Converging findings from a variety of disciplines are leading to the emergence of a fundamentally new view of the human mind, and with it a new framework for the behavioral and social sciences. First, with the advent of the cognitive revolution, human nature can finally be defined precisely as the set of universal, species-typical information-processing programs that operate beneath the surface of expressed cultural variability. Second, this collection of cognitive programs evolved in the Pleistocene to solve the adaptive problems regularly faced by our hunter-gatherer ancestors--problems such as mate selection, language acquisition, cooperation, and sexual infidelity. Consequently, the traditional view of the mind as a general-purpose computer, tabula rasa, or passive recipient of culture is being replaced by the view that the mind resembles an intricate network of functionally specialized computers, each of which imposes contentful structure on human mental organization and culture. The Adapted Mind explores this new approach--evolutionary psychology--and its implications for a new view of culture.

The psychological foundations of culture.

Abstract: One of the strengths of scientific inquiry is that it can progress with any mixture of empiricism, intuition, and formal theory that suits the convenience of the investigator. Many sciences develop for a time as exercises in description and empirical generalization. Only later do they acquire reasoned connections within themselves and with other branches of knowledge. Many things were scientifically known of human anatomy and the motions of the planets before they were scientifically explained.

Cognitive adaptations for social exchange.

Abstract: The human mind is the most complex natural phenomenon humans have yet encountered, and Darwin's gift to those who wish to understand it is a knowledge of the process that created it and gave it its distinctive organization: evolution. Because we know that the human mind is the product of the evolutionary process, we know something vitally illuminating: that, aside from those properties acquired by chance, the mind consists of a set of adaptations, designed to solve the long-standing adaptive problems humans encountered a s hunter-gatherers. Such a vie w i s uncontroversial to mos t behavioral scientists when applied to topics such as vision or balance. Yet adaptationist approaches to human psychology are considered radical—o r even transparently false—when applie d t o mos t other area s of human thought and action , especially social behavior. Nevertheless, the logic of the adaptationist postion is completely general, and a dispassionate evaluatio n of its implications leads to the expectation that humans should have evolved a constellation of cognitive adaptations to social life. Our ancestors have been members of social groups and engaging in social interactions for millions and probably tens of millions of years. To behave adaptively, they not only needed to construct a spatial map of the objects disclosed to them by their retinas, but a social map of the persons, relationships, motives, interactions, emotions, and intentions that made up their social world. Our view, then, is that humans have a faculty of social cognition, consisting of a rich collection o f dedicated, functionally specialized, interrelated modules (i.e., func tionally isolable subunits, mechanisms, mental organs, etc.), organized to collectively guide thought and behavior with respect to the evolutionarily recurrent adaptive problems posed by the social world. Nonetheless, if such a view has merit, it not only must be argued for on theoretical grounds—however compelling—but also must be substantiated by experimental evidence, as well as by converging lines of empirical support drawn from related fields such as neuroscience, linguistics, and anthropology.

The "What" and "Why" of Goal Pursuits: Human Needs and the Self-Determination of Behavior

Abstract: Self-determination theory (SDT) maintains that an understanding of human motivation requires a consideration of innate psychological needs for competence, autonomy, and relatedness. We discuss the SDT concept of needs as it relates to previous need theories, emphasizing that needs specify the necessary conditions for psychological growth, integrity, and well-being. This concept of needs leads to the hypotheses that different regulatory processes underlying goal pursuits are differentially associated with effective functioning and well-being and also that different goal contents have different relations to the quality of behavior and mental health, specifically because different regulatory processes and different goal contents are associated with differing degrees of need satisfaction. Social contexts and individual differences that support satisfaction of the basic needs facilitate natural growth processes including intrinsically motivated behavior and integration of extrinsic motivations, whereas those that forestall autonomy, competence, or relatedness are associated with poorer motivation, performance, and well-being. We also discuss the relation of the psychological needs to cultural values, evolutionary processes, and other contemporary motivation theories.

The role of positive emotions in positive psychology. The broaden-and-build theory of positive emotions.

Abstract: In this article, the author describes a new theoretical perspective on positive emotions and situates this new perspective within the emerging field of positive psychology. The broaden-and-build theory posits that experiences of positive emotions broaden people's momentary thought-action repertoires, which in turn serves to build their enduring personal resources, ranging from physical and intellectual resources to social and psychological resources. Preliminary empirical evidence supporting the broaden-and-build theory is reviewed, and open empirical questions that remain to be tested are identified. The theory and findings suggest that the capacity to experience positive emotions may be a fundamental human strength central to the study of human flourishing.

On Happiness and Human Potentials: A Review of Research on Hedonic and Eudaimonic Well-Being

Abstract: ▪ Abstract Well-being is a complex construct that concerns optimal experience and functioning. Current research on well-being has been derived from two general perspectives: the hedonic approach, which focuses on happiness and defines well-being in terms of pleasure attainment and pain avoidance; and the eudaimonic approach, which focuses on meaning and self-realization and defines well-being in terms of the degree to which a person is fully functioning. These two views have given rise to different research foci and a body of knowledge that is in some areas divergent and in others complementary. New methodological developments concerning multilevel modeling and construct comparisons are also allowing researchers to formulate new questions for the field. This review considers research from both perspectives concerning the nature of well-being, its antecedents, and its stability across time and culture.

An argument for basic emotions

Abstract: Emotions are viewed as having evolved through their adaptive value in dealing with fundamental life-tasks. Each emotion has unique features: signal, physiology, and antecedent events. Each emotion ...
