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.

In this, the work's third volume, findings from thousands of studies pertaining to behavior, broadly defined, are summarized. Traits covered include those involving personality, social behavior, criminality, work, and sex stereotypes. The eight chapters comprising Volume III are as follows:

1. Personality and Behavioral Tendencies

2. Social Behavior

3. Acquiring, Selling, and Consuming Behavior

4. Criminality, Near-Criminality, and Victimization

5. Education, Work, Social Status, and Territorial Behavior

6. Sex Stereotypes

7. Attitudes and Actions Toward Others According to their Sex

8. Ecologically Based Sex Differences

The Handbook of Sex Differences is of significant importance for any researcher, student, or professional who requires a comprehensive resource on sex differences.
