There are distinct emotional responses to gender differences in romantic relationships. For example, due to paternity uncertainty in males, jealousy increases in males over sexual infidelity rather than emotional. According to research more women are likely to be upset by signs of resource withdraw (i.e. another female) than by sexual infidelity. A large amount of data supports this notion. However, one must consider for jealousy the life stage or experience one encounters in reference to the diverse responses to infidelity available. Research states that a componential view of jealousy consist of specific set of emotions that serve the reproductive role. However, research shows that both men and women would be equally angry and point the blame for sexual infidelity, but women would be more hurt by emotional infidelity. Despite this fact, anger surfaces when both parties involved are responsible for some type of uncontrollable behavior, sexual conduct is not exempt. Some behavior and actions are controllable such as sexual behavior. However hurt feelings are activated by relationship deviation. No evidence is known to be sexually dimorphic in both college and adult convenience samples. The Jealousy Specific Innate Model (JSIM) proved to not be innate, but may be sensitive to situational factors. As a result, it may only activate at stages. One study discovered serious relationships are reserved for older adults rather than undergraduates. For example, it was predicted that male jealousy decreases as females reproductive values decreases.
