The Oxford Handbook of Evolutionary Psychology and Behavioral Endocrinology offers a comprehensive and compelling review of research in behavioral endocrinology from an evolutionary perspective on human psychology. Chapters, written by renowned experts on human behavior, explore a number of subtopics within one of three themes (1) development and survival, (2) reproductive behavior, and (3) social and affective behavior. Such topics include hormonal influences on life history strategy, mate choice, aggression, human hierarchical structure, and mood disorders. This Handbook is situated at the intersection of evolutionary psychology and behavioral endocrinology. Its interdisciplinary approach makes it an important resource for a broad spectrum of researchers, graduate students, and advanced undergraduates who are interested in studying the motivations and mechanisms that affect behavior.

Kinship ties - the close relationships found within the family - have been a central focus of evolutionary biological analyses of social behaviour ever since biologist William Hamilton extended the concept of Darwinian fitness to include an individual's actions benefiting not only his own offspring, but also collateral kin. Evolutionary biologists consider not only organisms' reproductive strategists, but also nepotistic strategists. If a person's genes are just as likely to be reproduced in her sister as in her daughter, then we should expect the evolution of sororal investment in the same way as one expects maternal investment. This concept has revolutionized biologists' understanding of social interaction and developmental psychologists' understanding of the family. However, kinship ties have largely been ignored in other areas of psychology, particularly social psychology.Family Relationships brings together leading theorists and researchers from evolutionary psychology and related disciplines to illustrate the ways in which an evolutionary perspective can inform our study and understanding of family relationships. The contributors argue that family psychology is relationship specific: the relationship between mother and daughter is different from that between father and daughter or that between brother and sister or sister and sister. In other words, humans have evolved specialized mechanisms for processing information and motivating behavior that deal with the distinct demands of being a mate, father, mother, sibling, child, or grandparent. Such an evolutionary perspective on family dynamics provides a unique insight into human behaviour.

The field of forensic psychology explores the intersection of psychology and the law. The purpose of this book is to examine topics in the field using the powerful, multidisciplinary, conceptually integrated approach that the natural sciences have embraced for decades with great success.Darwin's theory of evolution by natural selection is the meta-theoretical framework that unifies the field of biology. It unites research and understanding of the development, control, and organization of behavior. The study of humans, which includes all of the social sciences, is part of the field of biology. Darwin's theory provides a powerful meta-theoretical framework that can unify and energize forensic psychology, just as it has the biological sciences. Evolutionary processes undoubtedly shaped physiological characteristics to help solve problems of survival and reproduction. The lungs, for example, with their vast surface area and moist membranes are marvelous adaptions for extracting oxygen and releasing carbon dioxide. Natural selection is the only known process capable of shaping complex functional mechanisms. Just as it shaped physiological adaptations with specific problem-solving functions, it also shaped our thoughts and emotions to guide behaviors toward solving recurrent problems of survival and reproduction. With this logic, we can use knowledge of ancestral problems to guide our understanding of how the mind works.Evolutionary Forensic Psychology is a necessary step toward a unified and complete understanding of psychology and the law. It recognizes that crimes such as murder, non-lethal violence, rape, and theft are manifestations of evolutionarily recurrent selection when they gave individuals an advantage in competition for resources. Each of the chapters that comprise this volume has been selected to provide the first unified examination of important research contributions and future directions of Evolutionary Forensic Psychology.

Relationships with family are important to our emotional health and can play a significant role in our social success. We need our families and yet frequently have a great difficulty understanding them. Hundreds of books have been published with the goal of improving understanding and relationships among family and relationships; few, if any, have done so with an evolutionary approach. The Oxford Handbook of Evolutionary Family Psychology focuses on the reasons underlying family behavior and how a greater understanding of these factors can help us to better understand our own family behaviors. Recognizing that a deeper understanding of human families can be found through an understanding of similar phenomena in other species, the volume demonstrates how an understanding of family ties can inform understanding of our relationships to non-kin.

Sexual conflict -- what happens when the reproductive interests of males and females diverge -- occurs in all sexually reproducing species, including humans. The Oxford Handbook of Sexual Conflict in Humans is the first volume to assemble the latest theoretical and empirical work on sexual conflict in humans from the leading scholars in the fields of evolutionary psychology and anthropology. Following an introductory section that outlines theory and research on sexual conflict in humans and non-humans, ensuing sections discuss human sexual conflict and its manifestations before and during mating. Chapters in these sections address a range of factors topics and factors, including:- Sexual coercion, jealousy, and partner violence and killing- The ovulatory cycle, female orgasm, and sperm competition- Chemical warfare between ejaculates and female reproductive tractsChapters in the next section address issues of sexual conflict after the birth of a child. These chapters address sexual conflict as a function of the local sex ratio, men's functional (if unconscious) concern with paternal resemblance to a child, men's reluctance to pay child support, and mate expulsion as a tactic to end a relationship. The handbook's concluding section includes a chapter that considers the impact of sexual conflict on a grander scale, notably on cultural, political, and religious systems.Addressing sexual conflict at its molecular and macroscopic levels, The Oxford Handbook of Sexual Conflict in Humans is a fascinating resource for the study of intersexual behavior.

Psychological research has produced a rich body of empirical data documenting humanity's propensity to commit infidelity in the context of long-term relationships, but comparatively little work has been dedicated to synthesizing these data into an integrated framework that encompasses the full range of its processes, from why it occurs in the first place to how it affects the long-term relationship thereafter. This edited handbook integrates a broad range of topics such as characteristics related to the propensity to commit infidelity, sex differences in reactions to infidelity, our inclination to dissolve relationships after infidelity, and other responses to infidelity. It showcases contributions from experts in social psychology, evolutionary psychology, and others who specialize in research on romantic relationships. The handbook discusses the processes of infidelity alongside sources of variation, such as sexual orientation, developmental life history, individual differences, and culture. This volume captures the interdisciplinary quality of research on the predictors, nature, and consequences of infidelity for the broader social scientific community interested in trust in romantic relationships.

This handbook showcases the empirical and theoretical advancements in the evolutionary study of romantic relationships, tracing the psychological mechanisms that shape strategic computation and behavior across the lifespan of an intimate partnership. Written by global experts in their fields, each chapter provides an overview of historic and contemporary research on the psychological mechanisms and processes underlying initiation, maintenance, and dissolution of romantic relationships. The volume discusses popular and cutting-edge methods for data analysis and theory development, critically analyzing the state of evolutionary relationship science. It provides discerning recommendations for future research and integrates a broad range of topics (e.g., partner preference and selection, competition and conflict, jealousy and mate guarding, parenting, partner loss and divorce, and post-relationship affiliation) that are discussed alongside major sources of strategic variation in mating behavior, such as sex and gender diversity, developmental life history, neuroendocrine processes, technological advancement, and culture. The Oxford Handbook of Evolutionary Psychology and Romantic Relationships enriches students' and established researchers' views across a diverse cross-section of relationship scholars and clinicians to incorporate evolutionary theorizing into their professional work, including those interested in social change and continuity in social and cultural psychology, sociology, political science, healthcare, and related fields.

The last 20 years have witnessed tremendous growth in theoretical and empirical work on emotions, including groundbreaking work on anger, disgust, pride, shame, sexual jealousy, romantic love, and more. Such work has demonstrated that emotions pervade nearly all aspects of psychological life, and that emotions are key to survival and reproduction and are therefore prime targets of natural selection. Emotions have also been implicated in a variety of psychological disorders, from the obvious (depression, anxiety) to the much less so (schizoid personality disorder, borderline personality disorder).In The Oxford Handbook of Evolution and the Emotions, Laith Al-Shawaf and Todd K. Shackelford have gathered a group of leading scholars in the field to present a centralized resource for researchers and students wishing to understand emotions from an evolutionary perspective. Together, the chapters provide a comprehensive overview of the literature, with a special focus on 1) conceptual foundations of evolutionary approaches to the emotions, 2) specific emotions, such as love, jealousy, anger, pride, disgust, shame, and others, 3) the importance of emotions in daily life, and 4) emotion disorders. The volume consists of four parts; the first part covers conceptual foundations of evolutionary approaches to the emotions (Evolution and the Emotions: Conceptual Foundations). The second part consists of specific emotions (Evolutionary Approaches to Specific Emotions). The third part focuses on the role of emotions in daily life, including spheres such as friendship, romantic relationships, morality, and politics (Evolutionary Approaches to Emotions in Daily Life). The fourth and final part consists of chapters on distinct emotion disorders (Evolutionary Approaches to Emotion Disorders). Comprehensive and integrative in nature, this Handbook is as an essential resource for students and scholars from a diversity of fields wishing to build upon our theoretical and empirical understanding of the emotions.

The Oxford Handbook of Evolutionary Psychology and Religion offers a comprehensive and compelling review of research in religious beliefs and practices from an evolutionary perspective on human psychology. The chapters, written by renowned experts on human behavior and religion, explore a number of subtopics within one of three themes: (1) the psychological mechanisms of religion, (2) evolutionary perspectives on the functionality of religion, and (3) evolutionary perspectives on religion and group living.This handbook unites the theoretical and empirical work of leading scholars in the evolutionary, cognitive, and anthropological sciences to produce an extensive and authoritative review of this literature. Its interdisciplinary approach makes it an important resource for a broad spectrum of researchers, graduate students, and advanced undergraduates who are interested in studying the factors and mechanisms that underlie and/or affect religious beliefs and behaviors.

The Oxford Handbook of Comparative Evolutionary Psychology ambitiously brings together an eclectic and provocative body of work from some of the brightest minds in comparative psychology and evolutionary psychology, highlighting the strengths and insights of each field. Across chapters, readers will come to appreciate the new field of "comparative evolutionary psychology," which successfully combines laboratory and field approaches, drawing on diverse methodologies and theoretical viewpoints to elucidate the mysteries of animal behavior and cognition. This comprehensive volume includes coverage of: - Unique specializations in a wide range of taxa from insects, cephalopods, reptiles, corvids, canines, cetaceans, and primates- Communication, cooperation, social learning, memory and cognitition in different species- Controversial theories about the evolution of sometimes surprising abilities in species, both phylogenetically close to and distant from humans. Suitable for seasoned researchers and graduate students alike, this volume reflects a range of views on human and non-human behavior and cognition, and advances these topics in a wide range of species.

This breadth of coverage is unique, and ensures that the handbook provides essential reading for students and researchers in the fields of psychology, anthropology, criminology, sociology, ethology, biology, and behavioral ecology.

In species with internal fertilization, sperm competition occurs when the sperm of two or more males simultaneously occupy the reproductive tract of a female and compete to fertilize an egg (Parker, 1970). A large body of empirical research has demonstrated that, as predicted by sperm competition theory, males and females in many species possess anatomical, behavioral, and physiological adaptations that have evolved to deal with the adaptive challenges associated with sperm competition. Moreover, in recent years, evolutionary biologists and psychologists have begun to examine the extent to which sperm competition may have been an important selective pressure during human evolution. Some research has suggested that male humans, like males of many bird, insect, and rodent species, might be able to adjust the number of sperm they inseminate according to the risk of sperm competition. Other research has examined whether such responses might be accompanied by psychological changes that motivate human males to pursue copulations when the risk of sperm competition is high. Furthermore, there is research suggesting that aspects of human penile anatomy might function to enhance success in sperm competition. Much of this work has been controversial; some of the findings have been disputed and others have been greeted with skepticism. However, the idea that some aspects of human psychology and behavior might best be understood as adaptations to sperm competition remains intriguing and, in certain cases, very persuasive.

Although commonly believed that males are more promiscuous than females, new research has revealed that female infidelity is a common occurrence throughout the animal kingdom. Female Infidelity and Paternal Uncertainty is the first book to address how males deal with the consequences of female infidelity and the strategies they have evolved to try to avoid the possibility of raising an offspring they unknowingly did not sire. Each chapter deals with a specific evolved strategy developed to aid males in either limiting opportunities for their mate to be unfaithful or to 'correct' the by-products of infidelity should it occur. With sections including mate guarding, intra-vaginal tactics and paternity assessment, this book will appeal to researchers and graduate students in behavioral biology, evolutionary psychology, human sexuality, anthropology, sociology, reproductive health and medicine.

This book is an introduction to the emerging field of evolutionary cognitive neuroscience, a branch of neuroscience that combines the disciplines of evolutionary psychology and cognitive neuroscience. It outlines the application of cognitive neuroscientific methods (e.g., functional magnetic resonance imaging, transcranial magnetic stimulation, magneto- and electroencephalography, and the use of neuropsychiatric and neurosurgical patients) to answer empirical questions posed from an evolutionary meta-theoretical perspective. Chapters outline the basics of cognitive evolution and how the methods of cognitive neuroscience can be employed to answer questions about the presence of evolved cognitive adaptations. Written for graduate students and researchers, the book presents the major topics of study undertaken by evolutionary cognitive neuroscientists - such as language evolution, intelligence and face processing - and serves as a primer upon which to base further study in the discipline.
