Drawing primarily on the literature in experimental economics and social psychology, this article reviews key findings on gender differences for two aspects of competitiveness and competition: entry preferences and performance. Although women, relative to men, have been shown to shy away from competition and underperform in competitive environments, this article also discusses boundary conditions for these effects, such as the nature of the task or gender composition of the group, and highlights manifestations of these effects in applied domains, including in negotiations, the labor market, educational settings, and sports. Adopting social psychological frameworks of prescriptive norms and stereotypes, particularly social role theory, this article examines ways in which gender-incongruencies may underpin gender gaps in competition and gender-congruencies may alleviate them. Finally, this article considers implications for individuals and institutions as well as future directions in the field to continue finding ways to close gaps.

SummaryIn a previous cisternographic study of the cerebrospinal fluid (CSF) circulation in schizophrenic patients, indications for disturbed flow dynamics were found in 10 of 30 subjects. In order to replicate and investigate the clinical and pathophysiological significance of this finding, 39 schizophrenic patients and 42 healthy subjects were examined with an improved method for measurement of CSF circulation. 99mTc-DTPA was injected intrathecally and the gamma cisternograms were evaluated blindly. Correlations between cisternography findings and age, duration of disease, previous hospitalizations, positive or negative symptomatology, exposure to neuroleptics, psychiatric family history, CT findings and CSF levels of protein, tryptophan and monoamine metabolites, were calculated. Seven of the patients showed abnormalities in the cisternograms with a slow or obstructed flow of CSF over the convexities (P < 0.01) whereas none of the healthy volunteers showed abnormalities. There were no correlations between disturbed CSF circulation in the patients and the clinical and biochemical parameters, thus the significance of the deviations, similar to other biological aberrations found in schizophrenic patients, is not known. Recent developments in magnetic resonance imaging offer new possibilities to further examine CSF circulation abnormalities in schizophrenia.

Epidemiological studies have long reported that, in North America, patterns of suicidal behavior differ by gender: women “attempt” suicide; men “complete” suicide. Theories of suicidal behavior also differ according to gender. Traditionally, women are said to be suicidal for love; men, for pride and performance. Are these gender differences “real?” Are women's attempts “failed” suicides? Do suicidal men “succeed” when they kill themselves? Is women's self-definition dependent on love? Is men's dependent on performance? Evidence currently available does not support traditional theories of gender and suicidal behavior. As culturally shared assumptions, however, traditional theories may influence the suicidal choices of women and men, as well as the assumptions and research methods of suicidologists.

There is wide evidence for gender differences in competitive behavior and performance under pressure from experimental economics and single-sex professional sports. We analyze these differences in a sport with direct gender competition. Our unique data consist of over 500,000 observations from around 11,000 German ninepin bowling games of which around 15% are from mixed-gender leagues. Men perform better against women on average, but this is fully explained by differences in ability. Our results are robust to instrumenting for opposite gender using the sex composition of the opponent team. Gender differences in tight situations do not seem to play a role.
