Male and female jealousy is evoked by different threats! › Males Sexual infidelity › Females Emotional infidelity Found in many cultures.. A human universal? › U.S., Netherlands, Germany, Korea, Japan, Sweden Pietrzak, R.H., Laird, J.D., Stevens, D.A., Thompson, N.S. (2002). Sex differences in human jealousy: a coordinated study of forced- choice, continuous rating-scale, and physiological responses on the same subjects. Evolution and Human Behavior, 23, 83-94.

1) Forced-choice studies › Which event is more upsetting? 2) Continuous rating-scales › Report emotional reactions. 3) Physiological responses › Heart rate, electrodermal activity, electromyographic activity, blood pressure, temperature Pietrzak, R.H., Laird, J.D., Stevens, D.A., Thompson, N.S. (2002). Sex differences in human jealousy: a coordinated study of forced- choice, continuous rating-scale, and physiological responses on the same subjects. Evolution and Human Behavior, 23, 83-94.

Harris (2002): › Different studies find different proportions › Only one physiological measure showed sex differences (Buss et al. 1992) › Attempts to replicate failed to find female differences between the 2 threat types › Previous studies employ only one method Opposing theory: sexual infidelity implies emotional infidelity and vice versa. Pietrzak, R.H., Laird, J.D., Stevens, D.A., Thompson, N.S. (2002). Sex differences in human jealousy: a coordinated study of forced- choice, continuous rating-scale, and physiological responses on the same subjects. Evolution and Human Behavior, 23, 83-94.

Current Study Methods: › 47 undergrads (25 female, 22 male) › Use all three measures on each participant: 1.Forced choice 2.Continuous rating-scale 3.Physiological measures Pietrzak, R.H., Laird, J.D., Stevens, D.A., Thompson, N.S. (2002). Sex differences in human jealousy: a coordinated study of forced- choice, continuous rating-scale, and physiological responses on the same subjects. Evolution and Human Behavior, 23, 83-94.

Forced Choice: › 73% of males reported greater distress over sexual infidelity › 96% of females reported greater distress over emotional infidelity Pietrzak, R.H., Laird, J.D., Stevens, D.A., Thompson, N.S. (2002). Sex differences in human jealousy: a coordinated study of forced- choice, continuous rating-scale, and physiological responses on the same subjects. Evolution and Human Behavior, 23, 83-94.

Continuous rating-scale › Men: greater anger, rage, betrayal : sexual infidelity › Women: greater anger, anxiety, fear : emotional infidelity Physiological measures men: more responsive to sexual women: more responsive to emotional Pietrzak, R.H., Laird, J.D., Stevens, D.A., Thompson, N.S. (2002). Sex differences in human jealousy: a coordinated study of forced- choice, continuous rating-scale, and physiological responses on the same subjects. Evolution and Human Behavior, 23, 83-94.

Generalized autonomic arousal is elicited in response to different types of relationship threats in men and women. › Rage, betrayal male response to sexual infidelity › Anxiety, fear female response to emotional infidelity › Corroborates evolutionary theory of sexually differentiated jealousy response systems! Pietrzak, R.H., Laird, J.D., Stevens, D.A., Thompson, N.S. (2002). Sex differences in human jealousy: a coordinated study of forced- choice, continuous rating-scale, and physiological responses on the same subjects. Evolution and Human Behavior, 23, 83-94.

Strengths: › 1) 3 measures strengthen findings › 2) opens doors to finding specific mechanism Weaknesses: › 1) fails to discuss the why question Pietrzak, R.H., Laird, J.D., Stevens, D.A., Thompson, N.S. (2002). Sex differences in human jealousy: a coordinated study of forced- choice, continuous rating-scale, and physiological responses on the same subjects. Evolution and Human Behavior, 23, 83-94.
