David Buss

David M.Buss Ph.D. (born April 14, 1953) is a professor of psychology at The University of Texas at Austin, known for his evolutionary psychology research on human sex differences in mate selection.

David M.Buss probably the foremost evolutionary psychologist in the world.

David Buss is a full professor of psychology at the University of Texas. He is currently the head of the Individual Differences and Evolutionary Psychology Area and supervises a lab of evolutionary psychology Ph.D. students.

After completing his doctorate in 1981 at the University of California, Berkeley, David Buss spent four years as Assistant Professor at Harvard University. In 1985, he migrated to the University of Michigan, where he taught for 11 years before accepting his current position at the University of Texas in 1996. His primary interests include the evolutionary psychology of human mating strategies; conflict between the sexes; prestige, status, and social reputation; the emotion of jealousy; homicide; anti-homicide defenses; and stalking.

The primary topics of his research include mating strategies, conflict between the sexes, status, social reputation, prestige, the emotion of jealousy, homicide, anti-homicide defenses, and most recently stalking. All of these are approached from an evolutionary perspective. Buss is the author of more than 200 scientific articles and has won many awards. Some of these awards include American Psychological Association (APA) Distinguished Scientific Award for Early Career Contribution to Psychology in 1988 and APA G. Stanley Hall Lectureship in 1990.

Buss is the author of a number of publications and books, including The Evolution of Desire, The Dangerous Passion, The Handbook of Evolutionary Psychology and The Murderer Next Door, which introduces a new theory of homicide from an evolutionary perspective. He is also the author of Evolutionary Psychology: The New Science of the Mind which is currently in its third edition and was released in 2007. In 2005, Buss edited a definitive reference volume, The Handbook of Evolutionary Psychology. His latest book is entitled Why Women Have Sex, coauthored with Cindy Meston.

Buss is involved with extensive cross-cultural research collaborations and lectures within the U.S. His hobbies include tennis, squash, disc golf, and he is an avid film buff.

Act Frequency Approach

In science, it has proven to be very difficult, if not impossible, to find exact definitions for concepts of layman psychology, by either stating the conditions that constitute a certain personality trait, or by exhaustively listing all the acts that identify a bearer of that trait. What exactly defines an individual as "creative", "humorous", or "ambitious"? Equally difficult is the measurement of how strongly a trait is pronounced in an individual. As a solution, Buss and K. H. Craik (1980) proposed to introduce prototype theory into personality psychology.

First, a group of people is asked to list acts that a person bearing the trait in question would show. Next, a different group of people is asked to name from that list those acts that are most typical for the trait. Then the measurement is conducted by counting the number of times (within a given period of time), a proband performs the typical acts.
