When searching for a mate, one must gather information to determine the mate value of potential partners. By focusing on individuals who have been previously chosen by others, one's selection of mates can be influenced by another's successful search—a phenomenon known as mate copying. We show mate copying in humans with a novel methodology that closely mimics behavioral studies with nonhuman animals. After observing instances of real mating interest in video recordings of speed-dates, both male…

Generalization in mate-choice copying in humans
TLDR
It is found that whereas this kind of generalization did occur with some traits, it appeared to depend on age, and conspicuously, it did not occur with (inner) facial traits.
Female Mate Copying: Measuring the Effect of Mate-Relevant Information Provided by Former Partners
One of the most important decisions an individual can make is to invest in a relationship. For women, the process of mate selection can be time-intensive, and fraught with costs and dangers. However,
Evidence of Human Mate Copying
A variety of non-human females do not select male partners independently. Instead they favor males having previous associations with other females, a phenom- enon known as mate copying. This paper
Trait/Financial Information of Potential Male Mate Eliminates Mate-Choice Copying by Women: Trade-Off Between Social Information and Personal Information in Mate Selection.
TLDR
Women's strategic trade-off between such social learning and using the personal information of a potential mate is investigated, demonstrating human social learning strategies in mate selection through a trade-offs between social information and personal information.
Female mate copying explored: an inconsistent effect
Mate copying is a social phenomenon whereby individuals differentially evaluate opposite-sex others based on their relationship history. Here we report two studies that aimed to look at mate copying

TLDR
It is found that both the single and coupled women showed mate-choice copying, but their response patterns differed; the significant effects for single women were dependent on a decrease in attractiveness ratings when they perceived the models' mate rejection, however, the significant findings for coupled women relied on an increase in attractiveness Ratings when they observed the Models' mate acceptance.
Women’s Sensitivity to Men’s Past Relationships: Reliable Information Use for Mate-Choice Copying in Humans
Mate-choice copying is a phenomenon whereby females assess the mate quality of males based on the mating decisions of other females. Previous studies demonstrated that the presence of a partner
Nonindependent mate choice in humans
Mate choice copying is the most studied type of nonindependent mate choice, i.e. mate choice that is influenced by the choices of other same-sex conspecifics (usually females). In copying, the
A Biometric Analysis of Mate Choice Copying in People
TLDR
Pupil dilation might serve as a proxy for physical attractiveness in humans and can be measured objectively and it was found that Likert ratings of attractiveness and pupil sizes are moderately correlated and that presenting a picture of another alongside a target face can increase the target face's attractiveness.
Human mate-choice copying is domain-general social learning
Women appear to copy other women’s preferences for men’s faces. This ‘mate-choice copying’ is often taken as evidence of psychological adaptations for processing social information related to mate

Mate Choice Copying in Humans
TLDR
It is suggested that copying may be a conditional female mating tactic aimed at solving the problem of informational constraints on assessing male suitability for long-term sexual relationships, and that lack of mate choice experience is also an important determinant of copying.
Mate choice copying and mate quality bias: different processes, different species
TLDR
It is shown that this type of nonindependent mate choice is characterized by distinct evolutionary dynamics and ecological requirements, will have usually evolved in different species, and must therefore be urgently distinguished from mate choice copying.
Human mate choice and the wedding ring effect
TLDR
This study tested one of the hypotheses, the so-called wedding ring effect—that women would prefer men who are already engaged or married—in a series of live interactions between men and women, and casts doubt on some simplified theories of human mate-choice copying.
Mate-choice copying when both sexes face high costs of reproduction
TLDR
The results of this study indicate that in sticklebacks both sexes may reduce the costs of mate choice by copying the preferences of others.
Mate choice copying in monogamous species: should females use public information to choose extrapair mates?
Empirical evidence that females can copy each other's mating preferences comes predominantly from research on lekking species, but recent laboratory studies revealed that public information can also
Alternative mechanisms of nonindependent mate choice
TLDR
This framework reveals many ways in which one female's mate choice can influence that of another, and suggests a broader array of hypotheses about the selective forces acting on such mechanisms.
Different cognitive processes underlie human mate choices and mate preferences
TLDR
In a study of 46 adults participating in a speed-dating event, it was found that the stated preferences did not predict actual choices made during the speed-dates, and men chose women based on their physical attractiveness, whereas women, who were generally much more discriminating than men, chose men whose overall desirability as a mate matched the women's self-perceived physical attractiveness.
Mate choice copying and mate quality bias: are they different processes?
TLDR
It is generally accepted that mate choice copying is operationally a form of nonindependent mate choice resulting from social learning, in which an individual gains social information about potential mates by observing sexual interactions between nearby male and female conspecifics and uses this learned-association information later in choosing a mate.
Social transmission of face preferences among humans
TLDR
It is shown that observing other women with smiling expressions looking at male faces increased women's preferences for those men to a greater extent than did observing women with neutral expressions, potentially demonstrating a mechanism for social transmission of mate preferences.
The Ability to Judge the Romantic Interest of Others
TLDR
The results suggest that the ability to read nonverbal behavior quickly in mate choice is present not only for individuals in the interaction, but also for third-party observers.
