Jealousy and Infidelity Explanations Flashcards
One evolutionary explanation of human aggression based on jealousy is:
Cuckoldry and Sexual Jealousy
Men feel they are constantly at risk of cuckoldry. What is cuckoldry?
Reproductive cost inflicted on a man as a result of his partners infidelity
What is the consequence for a man of cuckoldry?
Man may unknowingly invest his resources (money, time etc) into a child that is not his own, which is very undesirable
What is the adaptive function of jealousy?
A mate is deterred from sexual infidelity, so there is a lesser risk of cuckoldry occurring
Another explanation based on jealousy focuses on:
Male retention and violence, among the strategies identified by Buss, that are designed to maintain a mate
Male retention strategies are strategies that:
- Have evolved over time
- Deter a mate from infidelity
- May include restricting partners autonomy or negative inducements in the form of violence of threats
Linked with male retention strategies, what did one study into battered women find?
Many reported sexual jealousy as being the trigger, showing those perceived as being unfaithful are at a higher risk of violence due to jealousy
Sexual Jealousy can also lead to violence on a more extreme level…
UK and US: most common motivation for murder in domestic disputes, accounting for 17% of murders
What does sexual jealousy and murder rates show?
Reinforces the idea that jealousy has evolved for its reproductive advantages of deterring a mate from infidelity
A strength of research into the effect of jealousy and human aggression is that it has considerable research support…
Shackle ford used 461m/560f in committed hetero relationships. Males answered Qs on male retention techniques and the frequency, females answered Qs regarding their male partners and their use of male retention strategies and the degree of violence used
What did Shacklefords study find?
Use of two broad retention techniques were directly linked with violence and use of emotional manipulation could predict violence against women. Confirmed by female participants.
However, a limitation of Shacklefords research into jealousy and human aggression is that it has methodological flaws.
Reliance on self report techniques - untruthful answers to avoid judgement/sensitive topic. Lacks validity and consequently cannot be applied to the general population.
Further research by Buss and Shackleford gives credit to the connection between sexual jealous, MRSs and violence…
-Greater punishment used by men who suspected their partners of being unfaithful than by those who did not expect future infidelities
What do the results of Buss and Shacklefords study demonstrate?
- Consistent with evolutionary claim that MRSs have evolved over many years and are evoked only when an adaptive problem is faced
What is a positive application of research into the link between jealousy and human aggression?
-Awareness of early indicators, can act as a signal to friends and families that violence may be to follow. Can protect many women from violence and potentially murder, so research has invaluable practical applications
