Abstract:

Human asexuality is generally deﬁned as a lack of sexual attraction. Various theories have been proposed to explain how asexuality should best be conceptualized, including that asexuality should be classified as a sexual orientation, that it is due to a mental health difficulty, that it is an extreme variant of hypoactive sexual desire disorder (HSDD), or that some asexual individuals actually experience a paraphilia of some kind. This dissertation employed a series of Internet-based research studies to investigate these three topics: an examination into mental health correlates of asexuality,

Abstract:

The LOOK is an iPad-based application that measures sexual interest. It does this by recording the amount of time individuals take to view and rate the attractiveness of images of fully clothed people from differing age, gender, and racial demographics. Viewing-time measures, such as the LOOK, operate under the assumption that individuals view sexually attractive images longer than they view images that they deem unattractive or sexually non-preferred. Although there is research to show the efficacy of these kinds of tests, there is a lack of research supporting the assumption that viewing-tim

ABSTRACT Background: Sexual orientation is comprised of distinct components, including sexual identity, sexual attraction and sexual behavior. Lesbian, gay and bisexual adolescents are at an increased risk of experiencing poor health outcomes compared to non-sexual minority youth. Health care professional organizations recommend that health care providers discuss each component of sexual orientation at every adolescent health supervision visits in order to best assess the adolescent's health risks and needs for intervention and education.

Using family photos, judgements of faces of parents and offspring revealed that facial sexual-dimorphism is passed on from father to son and mother to daughter, while inheritance of attractiveness is apparent only in daughters.

In economic games the facial attributes of counterparts bias decisions to trust and decisions to enter play. We report research supporting hypotheses that trust and reciprocation decisions in trust games are biased by mechanisms of sexual selection. Hypotheses that trust game behaviour is modulated by inter-sexual competition were supported. 1) Attractive individuals elicit more cooperation. 2) Male participants display trust and reciprocation toward attractive female counterparts in excess of perceived trustworthiness (and this display is modulated by male self-reported physical dominance). 3

In this thesis, I aimed to explore vocal attractiveness from an evolutionary perspective: how listener's preferences for vocal qualities of potential partners could increase mating success and reproductive success.

In chapter 5, I correlated attributions made to voices to the acoustic properties of the voices. In men's voices, pitch negatively predicted vocal attractiveness. Attributions of masculinity, size, age, health and vocal attractiveness were all positively correlated.

Abstract:

Sexual selection shaped psychological mechanisms in both sexes to assess potential mates for evidence of mate quality (Buss, 2005). Attraction preferences are one such mechanism (Sugiyama, 2005) and physical attraction preferences are sensitive to fitness-promoting traits present in a potential mate. Physically attractive traits are thought to act as signals of good genetic quality (Neff & Pitcher, 2005) and are preferred because of the advantage such quality bestows towards reproductive success. Specifically, genetic quality is proposed to be a biological requirement necessary for physically

Chez la souris, la puberté de la femelle est accélérée par des phéromones urinaires émises par le mâle (effet Vandenbergh). Les mécanismes neuroendocriniens sous-Jacents et les conséquences comportementales restent peu connus. Par une approche multidisciplinaire alliant immunohistochimie, chromatographie gazeuse couplée à la spectrométrie de masse et chirurgie expérimentale, mon travail de thèse montre que les neurones synthétisant la kisspeptine, un neuropeptide hypothalamique jouant un rôle essentiel dans le contrôle de la puberté, sont régulés positivement par les phéromones accélératrices

Abstract:

Over the last century, sexual selection has grown from a controversial theory into a vast field of theoretical and empirical research. Although Darwin outlined two major mechanisms within his theory, male-male competition and female mate choice, the latter has promoted a wealth of research by virtue of its complexity. Despite decades of research into how female preferences and sexually selected traits have evolved, there is still little consensus as to why females prefer the males they do. Preferences are thought to evolve from either direct selection on the preference, as females themselves b

Abstract:

LGB individuals seek out counseling at higher rates than their straight counterparts and they tend to present for counseling with concerns that are unique and different from heterosexuals, such as difficulty reconciling one's sexual orientation with one's own religious beliefs. Yet counselors and counselors-in-training indicate that they have received very little education and/or training for working competently with LGB clients or with clients dealing with issues of religion and spirituality. The counseling profession could benefit from research providing in-depth and descriptive informatio

Abstract:

Il a été montré que les termites les plus archai͏̈ques et ceux qui ne sortent pas du bois sécrètent une phéromone de piste. Ce terme recouvre toutefois une hétérogénéité fonctionnelle. La phéromone de piste de 33 espèces a été identifiée. Les Mastotermitidae et les Termopsidae Porotermitinae et Stolotermitinae possèdent la même phéromone de piste (alcool en C14). Les Termopsidae Termopsinae sécrètent une molécule voisine (aldéhyde en C14). Les Kalotermitidae possèdent le dodécénol comme phéromone de piste. Les Rhinotermitidae ont le dodécatriénol, sauf les Prorhinotermes qui sécrètent du néoce

Abstract:

Evolutionary psychology explains and predicts human behaviour based on its adaptive value. Some apparently non-adaptive behaviours such as humans’ devotion to music can be explained by sexual selection of costly signals, since it takes time and effort to learn to play an instrument well. Here, participants rated pictures of persons of the opposite sex that were said to play a piece of music that was heard while watching each picture. The music performances were either of low, medium, or high level of skill, and a better performance was predicted to lead to higher ratings of partner attractiven

Abstract:

Parmi les modes de communication les plus exploités chez les insectes, la communication chimique figure en bonne place. D’ailleurs, la recherche moderne consacrée aux signaux chimiques émis et perçus par les individus d’une même espèce n’a de cesse de se développer depuis plus de 50 ans. A travers ce travail de thèse, nous nous sommes intéressés à ces phéromones associées au comportement sexuel de Gastrophysa viridula (Coleoptera :Chrysomelidae). Nous avons menés, dans ce cadre, plusieurs bioessais comportementaux liés pour la plupart à des analyses chimiques par chromatographie gazeuse couplé
