Biopsychology is a branch of psychology that analyzes how the brain and neurotransmitters influence our behaviors, thoughts, and feelings. It is a subdivision of behavioral neuroscience that studies the neural mechanisms of perception and behavior through direct manipulation of the brains of nonhuman animal subjects in controlled experiments. Biopsychology studies many topics relating to the body's response to a behavior or activity in an organism. It concerns the brain cells, structures, components, and chemical interactions that are involved in order to produce actions. Psychologists in this.

The psychology classic—a detailed study of scientific theories of human nature and the possible ways in which human behavior can be predicted and controlled—from one of the most influential behaviorists of the twentieth century and the author of Walden Two. “This is an important book, exceptionally well written, and logically consistent with the basic premise of the unitary nature of science. Many students of society and culture would take violent issue with most of the things that Skinner has to say, but even those who disagree most will find this a stimulating book.” —Samuel M. Strong, The American Journal of Sociology “This is a remarkable book—remarkable in that it presents a strong, consistent, and all but exhaustive case for a natural science of human behavior…It ought to be…valuable for those whose preferences lie with, as well as those whose preferences stand against, a behavioristic approach to human activity.” —Harry Prosch, Ethics

When biological theories were used to understand behavior in the early 20th century, they were often poorly understood. Ideas about race, ethnicity, and IQ, and notions of social Darwinism, were based on a misunderstanding and an incomplete understanding of genetics and Darwin s theory of evolution by natural selection. Now, however, a biological understanding of social behavior is an integral part of modern science, and increasingly used in the study of behavior in organizations. Yet, compared with other explanatory paradigms in organizational behavior, biological and evolutionary approaches are still relatively rare. "The Biological Foundations of Organizational Behavior" provides accessible insights for scholars and practitioners in management and organizational behavior into what biology can offer their fields. Chapters contain enough background to orient readers who may have little knowledge of biology, and provide substantive contributions to advancing understanding of specific areas of biology and human behavior in organizations. They also show how the addition of biological theory and research to organizational-behavior scholarship will increase its explanatory and predictive power and contribute to its scientific foundations."

The Cannibal Within offers an evolutionary account of the propensity of human beings, in extreme circumstances to eat other human beings, despite the strong Western taboo against such practices. What sets this volume apart from the large body of literature on cannibalism, both popular and anthropological, is the underlying premise: cannibalism as an alternative to starvation is tacitly condoned by the same biological morality that would condemn cannibalism of other sorts in non-threatening situations. Deep as the taboos may be, the survival instinct runs even deeper. The title of the book reflects the author's belief that cannibalism is not a pathology that erupts in psychotic individuals, but is a universal adaptive strategy that is evolutionarily sound. The cannibal is within all of us, and cannibals are within all cultures, should the circumstances demand cannibalism's appearance and usage. Petrinovich's work is rich in historical detail, and rises to a level of theoretical sophistication in addressing a subject too often dealt with in sensationalist terms. The major instances in which survival cannibalism has occurred convinced the author that there is a consistent pattern and a uniform regularity of order in which different kinds of individuals are consumed. In considering who eats whom, when, and under what circumstances, this regularity appears, and it is consistent with what would be expected on the basis of evolutionary or Darwinian theory. In short, he concludes that starvation cannibalism is not a manifestation of the chaotic, psychotic behavior of individuals who are driven to madness, but reveals underlying characteristics of evolved human beings. Lewis Petrinovich is professor emeritus in the Department of Psychology of the University of California, Riverside and is currently a resident of Berkeley, California.

The human race spends a disproportionate amount of attention, money, and expertise in solving, trying, and reporting homicides, as compared to other social problems. The public avidly consumes accounts of real-life homicide cases, and murder fiction is more popular still. Nevertheless, we have only the most rudimentary scientific understanding of who is likely to kill whom and why. Martin Daly and Margo Wilson apply contemporary evolutionary theory to analysis of human motives and perceptions of self-interest, considering where and why individual interests conflict, using well-documented murder cases. This book attempts to understand normal social motives in murder as products of the process of evolution by natural selection. They note that the implications for psychology are many and profound, touching on such matters as parental affection and rejection, sibling rivalry, sex differences in interests and inclinations, social comparison and achievement motives, our sense of justice, lifespan developmental changes in attitudes, and the phenomenology of the self. This is the first volume of its kind to analyze homicides in the light of a theory of interpersonal conflict. Before this study, no one had compared an observed distribution of victim-killer relationships to "expected" distribution, nor asked about the patterns of killer-victim age disparities in familial killings. This evolutionary psychological approach affords a deeper view and understanding of homicidal violence.

This comprehensive, authoritative handbook covers the breadth of theories, methods, and empirically based findings on the ways in which children and adolescents contribute to one another's development. Leading researchers review what is known about the dynamics of peer interactions and relationships from infancy through adolescence. Topics include methods of assessing friendship and peer networks; early romantic relationships; individual differences and contextual factors in children's social and emotional competencies and behaviors; group dynamics; and the impact of peer relations on achievement, social adaptation, and mental health. Salient issues in intervention and prevention are also addressed.
