Behavioral Immunity Of Olfactory Channels: The Role Of Female Body Aversion Sensitivity In Mate Selection

If mating is the core of evolution,choosing a spouse is an essential step in mating.Only the right choice of spouse can protect the survival of themselves and future generations,in order to inherit good genes to future generations and better continue their lives.Therefore,how to choose a spouse,how to identify the genetic quality and health status of potential spouses is also a problem that has remained unchanged since ancient times.Previous studies have found that both animals and humans are more inclined to use individuals with high attractiveness as their spouses.The attractiveness of potential expression of gene quality and health status can be attributed to the effectiveness of behavioral immunity.Previous studies have focused on the role of visual immunity in mate selection,and lack of research on the role of behavioral immunity in olfactory channels in mate selection.Therefore,this paper explores the role of behavioral immunity in olfactory channels in mate selection.Because women's sense of smell is more sensitive,the subject of this study is women.Study 1 uses the investment weighing task to investigate the effect of behavioral immunity on mate selection in the olfactory channel.It is found that the behavioral immunity of the olfactory channel plays a role in mate selection.Women with higher aversion and aversion sensitivity prefer the genetic characteristics in mate selection,especially with A more relevant smell smells this feature.Study 2 uses e-prime to write a program to render face images on a computer.Participants were asked to use the characters in the face image as potential spouses and to score attractively.The test will let the test smell the sample before the evaluation.The study was divided into an experimental group and a control group.The odor sample of the experimental group was a sealed,transparent plastic bag containing a cotton pad containing a body odor,and the odor sample of the control group was a sealed,transparent plastic bag containing an unused cotton pad.It was found that in the actual mate selection scenario,women's odor aversion sensitivity affects women's mate selection behavior by affecting their perception of odor aversion.Study 3 added disease clues(sickness initiation vs.control)based on study 2,and the disease initiation group watched a short video of stimuli associated with activating individual aversion,and the control group watched the film "Jaws" interception.It was found that under the condition of disease initiation,the perception of the level of aversion of odor was enhanced by women with high sensitivity and long-term mate,and the target task became the attractive level of potential spouse.This study found the effect of behavioral immune function of olfactory channels on female mate selection behavior.The higher the sensitivity of women's body aversion,the more important the genetic characteristics and the more directly related odor characteristics,and affect the individual's mate selection behavior by affecting the individual's perception of odor aversion.The behavioral immune function of the olfactory channel is flexible in the influence of female mate selection behavior.Under the condition of disease initiation,the individual with high sensitivity to aversion is perceived to have an increased level of odor aversion,thereby reducing the attractiveness of the scent provider as a mate.
