The Handbook of Sex Differences is a four-volume reference work assembled and written to assess sex differences in human traits (although findings regarding other species are also included). Based on the authors’ highly influential 2008 book Sex Differences, these volumes highlight important new research findings from the last decade and a half alongside earlier findings. Conclusions reached by meta-analyses are also included. This, the work’s second volume, summarizes results from thousands of studies pertaining to cognition, broadly defined. Variables related to perceptual and motor skills, emotions, intellectual abilities, and mental disorders are among those examined. Even sex differences in attitudes, beliefs, preferences, and interests are documented in this volume. The seven chapters comprising Volume II are as follows:9. Perceptual Abilities and Motor Functioning10. Emotional Factors11. Cognitive, Academic, and Intellectual Factors12. Learning, Memory, Knowledge, and Cognitive States13. Self-Assessments and States Of Mind14. Mental Health and Illness15. Attitudes, Beliefs, Interests, and PreferencesThe Handbook of Sex Differences is of importance for any researcher, student, or professional who requires a comprehensive resource on sex differences.

The Handbook of Sex Differences is a four-volume reference work written to assess sex differences, with a primary focus on the human species. Based on the authors’ highly influential 2008 book Sex Differences, these volumes highlight important new research findings from the last decade and a half alongside earlier findings. In this, the work’s fourth and last volume, two related questions are addressed: Are there universal sex differences (i.e., sex differences found in all societies)? And if the answer is yes, what are they and how can each one be theoretically explained? To answer the first of these two questions, this volume condenses much of the research findings amassed in the book’s first three volumes into summary tables. Then, to help identify likely universal sex differences, three versions of social role theory and two versions of evolutionary theory are examined relative to each possible universal sex difference. Consideration is even given to religious scriptures as a sixth type of explanation. In the concluding analyses, 308 likely universal sex differences are identified. No single theory was able to explain all these differences. Nevertheless, the two evolutionary theories were better in this regard than any of the three social role theories, including the recently proposed biosocial version of social role theory. The Handbook of Sex Differences is of importance for any researcher, student, or professional who requires a comprehensive resource on sex differences.

Conclusions reached by meta-analyses are also included. In this, the work’s first volume, findings from thousands of studies are summarized regarding basic biology. Results having to do with sex ratios at birth and traits involving a wide range of bodily features are reported along with numerous complex aspects of biochemistry, neurology, and physical health.

Migration between Newfoundland and Alberta is transforming the social and cultural landscape of Canada. Newfoundlanders involved in this migration overcome the many challenges it entails with countless acts of altruism; ranging from supplying a place to live and help in finding a job, to providing a familiar meal or a ride home for Christmas. Although such kindness is a familiar part of human behavior, social scientists have struggled to explain it because they adhere to the assumption that all human behavior is driven by hedonistic self-interest. As a result, most social scientists only succeed in explaining human kindness away by arguing that what appears to be altruistic is really only an investment that will lead to future selfish gains. This book provides an alternative explanation of the kindness exhibited by Newfoundlanders as they overcome the obstacles inherent in migration. This new explanation incorporates cultural traditions into existing evolutionary explanations of altruism. This explanation, referred to as the descendant-leaving strategy hypothesis, explains human kindness as the result of our ancestors passing on cultural traditions encouraging each following generation of descendants to value the well-being of their kin as much as they value themselves. This hypothesis is supported by descriptions of how traditions of kindness, passed down through generations of Newfoundlanders, continue to influence the behavior of Newfoundlanders as they face the social and physical challenge of migrating to Alberta.

Spanning many different epochs and varieties of religious experience, this book develops a new approach to religion and its role in human history. The authors look across a range of religious phenomena-from ancestor worship to totemism, shamanism, and worldwide modern religions-to offer a new explanation of the evolutionary success of religious behaviors. Their book is more empirical and verifiable than most previous books on evolution and religion because they develop an approach that removes guesswork about beliefs in the supernatural, focusing instead on the behaviors of individuals. The result is a pioneering look at how and why natural selection has favored religious behaviors throughout history.
