Westermarck Effect by Saara Lamberg. Figure 2 shows that attractiveness ratings by men were highest for sibling morphs and for women for nonkin. Facial preference toward stimulus morphs self-similar, dark grey; sibling similar, lightgrey; and nonkin similar, white for male and female participants.
In this study, we tested for negative sexual imprinting and the Westermarck effect in humans. We predicted that, if humans are adapted to avoid inbreeding, preferences for self- and sibling-resembling faces would be lower than those for nonkin faces. We did not find general support for this prediction, but we found a sex-specific effect such that women preferred nonkin faces significantly more than those morphed with their sibling and men preferred sibling-resembling faces more than nonkin and self-similar faces.
This sex-specific asymmetry in sexual aversion to kin is consistent with a parental investment theory of inbreeding avoidance.
Females are proposed to bear higher minimum proximate costs associated with inbreeding depression, causing them to develop deeper aversion toward engagement in sexual activities with male individuals who bear cues of relatedness Trivers ; Tooby ; Hang Our finding is consistent with those of previous studies, albeit using different methods, which show that aversion toward siblings is stronger for women than for men Walter and Buyske Therefore, women should be better equipped for detecting similarity, as the putative costs of inbreeding depression are stronger for them than for men.
Interestingly, men showed stronger preferences for faces that resembled their sibling. Therefore, our results could be interpreted as a positive sexual imprinting-like mechanism that is extended to siblings. It is interesting, then, that the same effect was not found for self-morphs for men. The observed difference between preferences for self- and sibling-morphed stimuli sheds light on the exposure effect proposed to account for kin attraction proposed among others by Freud Also in later studies, it has been showed that increased familiarity with a presented stimulus can enhance rated attractiveness of the stimulus Zajonc Sibling morphs were rated as significantly higher in attractiveness than self-morphs by men, meaning that self-referent phenotype matching could not be responsible for the attraction toward close kin, as it was visible significantly only in sib, but not self-morphs in men.
As the genetic and phenotypic similarity between siblings can differ, using the real sibling for stimuli pictures can have variable outcomes when expecting inbreeding avoidance based on phenotype matching. Broadly speaking, mating strategies are an adaptive behavior functioning in present but shaped in the past—when phenotype matching could not be based solely on self, as mirrors were not accessible pointed out also in Debruine et al.
Hence, a definite advantage of using this method to test negative imprinting is that it projects the real-life situation cohabitation with a sibling and a sibling being the direct stimulus for creation of inbreeding avoidance better than composite faces based on self-picture.
Our results showed no significant change of preference when judging picture of self-similar faces comparing both with that of sib morph and nonkin morph. This would mean that a switch of preference is triggered by similarity to kin rather than similarity to self.
Our results are valuable as they not only confirm the results of the previous studies on positive sexual imprinting among others Bereczkei et al. Furthermore, we postulate that sibling morphs and not self-morphs are more sensitive for tests of preference using changes in similarity and are likely to be more ecologically valid.

Early proximity and intimacy between siblings and incestuous behavior: Men do not have a stronger preference than women for self-resemblant child faces.
Sexual imprinting is the process by which a young animal learns the characteristics of a desirable mate. For example, male zebra finches have been shown to prefer mates with the appearance of the female bird that rears them, rather than mates of their own type Immelmann, The Westermarck effect is a kind of "reverse" sexual imprinting, seen when two people live in close domestic proximity during the first few years in the life of either one, resulting in desensitization to later close sexual attraction and bonding between them.
The Westermarck effect has since been observed in many places and cultures, including in the Israeli kibbutz system, and the Shim-pua marriage customs of Taiwan, as well as in biologically related families.
In the case of the Israeli kibbutz farms, children grew up in a common children's house, away from their parents. They spent the entire day and night together.
This resulted in a generation that was not interested in the opposite sex within their class. However, this is an extreme example of grouping since their parents were also removed from the environment.
When this does not occur, for example where a brother and sister are brought up not knowing about one another, they may find one another highly sexually attractive when they meet as adults—a phenomenon known as genetic sexual attraction. This observation is consistent with the theory that the Westermarck effect evolved to suppress inbreeding. This idea brought Westermarck in conflict with Sigmund Freud. Freud argued that members of the same family naturally lust for one another, making it necessary for societies to create incest taboos.
Psychoanalysts have continued to support the Freudian concept, arguing that such taboos would obviously be meaningless if there was no desire to perform the acts in question. Westermarck, however, argued the reverse, that the taboos themselves arise naturally as products of a simple inherited epigenetic response.
Subsequent research over the years has supported Westermarck's observations and interpretation. Westermarck left a visible mark on the development of both Finnish and European modern philosophical and sociological thought.
As a philosopher, Westermarck worked on a scientific basis for moral philosophy, approaching it from the anthropological and ethnological side, and grounding morality in emotion rather than reason.
This added a more human component to philosophy, which is continued in the strains of psychology, sociology, anthropology, and other social sciences that have been included in the modern philosophical paradigm. As a sociologist and anthropologist, Westermarck contributed toward the understanding of the institution of marriage , especially the practice of exogamy. His research on incest revealed what is called the Westermarck effect.
While this finding contributes significantly to our understanding of human family relationships, without a clear understanding of the role of parents in the process, his work is not complete. The Westermarck Society was founded in , to continue the spirit of his work. It has published several journals, among which are Sosiologia Sociology , Acta Sociologica, and the Transactions of the Westermarck Society series.

Aug 04, · The Westermarck effect is the phenomenon that people who are raised together usually are not sexually attracted to each other in.
Psychology Definition of WESTERMARCK EFFECT: the postulation that individuals who are reared nearby or in the same home do not find each other sexually appealing when they're older. It is based upon t.
Westermarck () hypothesized that proximity to others during development serves as a cue to biological relatedness and hence is critical for sibling sexual aversion (the “Westermarck effect”). The Westermarck Effect is commonly brought up in the midst of shipping arguments shipping discussions where incest, cousins, and childhood friends are involved. A form of reverse sexual imprinting, the Westermarck Effect serves to suppress inbreeding in humans, working in opposition to the theorized genetic sexual attraction phenomenon.
