Sex differences in jealousy: not gone, not forgotten, and not explained by alternative hypothesis

Article Abstract:

The double-shot (DS) hypothesis fails to give an appropriate explanation about the sex differences in the weighting given to cues triggering sexual jealousy. It states that this difference is due to perceptual differences about the conditional probabilities of sexual and emotional infidelity. The hypothesis fails to explain the reasons for this difference. Sex differences are real and are independent of differences in socialization. However, the evolutionary hypothesis successfully accounts for these sex differences in reactions to infidelity.

Sex differences in jealousy in evolutionary and cultural perspective: tests from the Netherlands, Germany, and the United States

Article Abstract:

Studies in the United States, Netherlands and Germany reveal that men and women differ in the weighting given to factors triggering sexual jealousy, and that the magnitude of the sex differences varies across cultures. This lends support to the evolutionary and cultural perspectives on sex and jealousy. Women give more importance to emotional infidelity, whereas, men give more importance to sexual infidelity. The evolutionary psychology of sexual jealousy and the influence of cultural input are discussed.

Sex differences in jealousy: evolution, physiology, and psychology

Article Abstract:

Sex differences in jealousy were studied in three experiments. Sexual infidelity and emotional infidelity responses were measured across the sexes in the first experiment. Physiological responses were measured in both sexes in study two while the subjects imagined sexual or emotional infidelity of their partners. Study 3 measured the effect of jealousy in a committed sexual relationship. Results showed marked gender differences which confirm the hypotheses.
