this study investigates the relationships between iranian efl teachers’ perfectionism, burnout and their teaching style preferences, and also the difference between male and female efl teachers and their teaching style preferences. to this end, a sample of 99 efl teachers (46 males and 53 females), who had years of teaching experience, were selected. the measurement scales used in this study we...

Symmetry and masculinity in human faces have been proposed to be cues to the quality of the owner. Accordingly, symmetry is generally found attractive in male and female faces and femininity is attractive in female faces. Women’s preferences for male facial masculinity vary in ways that may maximise genetic benefits to women’s offspring. Here we examine sameand opposite-sex preferences for both...

Sexual preferences in animals are often skewed toward mates with exaggerated traits. In many vertebrates, parents provide, through the learning process of "sexual imprinting," the model for the later sexual preference. How imprinting can result in sexual preferences for mates having exaggerated traits rather than resembling the parental appearance is not clear. We test the hypothesis that a by-...

Virtual reality (VR), as a method to assess sexual preferences, is explored. Dynamics of the subjective point of view (POV), subjective affective state, and feeling of presence, as measured following the interaction with a virtual naked model, appear as promising ways to probe sexual preferences as expressed in immersion. Theoretical aspects of VR psychology and further steps in developing a se...

Sexual isolation, a reproductive barrier, can prevent interbreeding between diverging populations or species. Sexual isolation can have a clear genetic basis; however, it may also result from learned mate preferences that form via sexual imprinting. Here, we demonstrate that two sympatric species of mice-the white-footed mouse (Peromyscus leucopus) and its sister species, the cotton mouse (P. g...

We trained chickens to react to an average human female face but not to an average male face (or vice versa). In a subsequent test, the animals showed preferences for faces consistent with human sexual preferences (obtained from university students). This suggests that human preferences arise from general properties of nervous systems, rather than from face-specific adaptations. We discuss this...

According to theory, directional female choice for male sexual ornaments is expected to erode underlying genetic variation. Considerable attention, in this regard, has been given to understanding the ubiquity of heritable genetic variation in both female choice and male sexual traits. One intriguing possibility emerging from this work is that persistent genetic variation could be maintained, ov...

Female mating preferences are often flexible, reflecting the social environment in which they are expressed. Associated indirect genetic effects (IGEs) can affect the rate and direction of evolutionary change, but sexual selection models do not capture these dynamics. We incorporate IGEs into quantitative genetic models to explore how variation in social environments and mate choice flexibility...

Introduction. Past research indicates that sexual self-disclosure, or the degree to which an individual is open with his or her partner about sexual preferences, is a key aspect of sexual satisfaction and that partner’s lack of knowledge about one’s sexual preferences is associated with persistent sexual dysfunction. Aims. To replicate and extend past research by examining (i) how one’s own lev...

A novel explanation of the evolutionary process leading to the appearance of differences in sexual preferences is proposed. The explanation is fully general: it is not specific to any particular type of sexual preferences, nor to any species or population. It shows how different sexual preferences can appear in any large group-living population in which sexual selection is sufficiently strong i...
