Conductas sexuales online y sus motivaciones: Una aproximación desde la diversidad sexual

2020

El uso de Internet con objetivos sexuales (cibersexo) es una actividad cada vez más generalizada en todos los sectores de la población. Sin embargo, el modo en el que se realiza (frecuencia, tipos de actividad sexual online –ASO–, motivaciones, etc.) puede cambiar en función de características como la orientación sexual. Cuando el hecho de sentir atracción sexual hacia personas del mismo sexo suponía mayor rechazo y estigmatización que en la actualidad, el cibersexo constituía un espacio seguro donde experimentar con la sexualidad; así, era fácil comprender que su consumo entre personas homosexuales y bisexuales fuera superior. Actualmente, su empleo como espacio seguro parece quedar en seg…

Sex-pairing pheromones and reproductive isolation in three sympatric Cornitermes species (Isoptera, Termitidae, Syntermitinae)

2011

International audience; The species-specificity of pairing has been studied in three sympatric Neotropical termites: Cornitermes bequaerti, Cornitermes cumulans and Cornitermes silvestrii (Termitidae, Syntermitinae). Bioassays showed that sex attraction was highly species-specific between C. bequaerti and C cumulans but not between C. cumulans and C. silvestrii. The sex-pairing pheromone of the three species is secreted by the tergal glands of female alates. It consists of a common compound (3Z,6Z,8E)-dodeca-3,6,8-trien-1-ol. In C. bequaerti, this polyunsaturated alcohol is the only compound of the sex-pairing pheromone, whereas it is associated with the oxygenated sesquiterpene (E)-nerolid…

Influence of sexual appeal in roadside advertising on drivers' attention and driving behavior.

2019

Sexual appeals are widely used in advertising to attract consumers' attention. It has already been proved that they influence the addressee's cognitive processing, which in turn raises the question if sexual appeals may pose a serious threat for road safety when used in roadside advertising. Three studies were designed to answer this question. Study I was a nationwide survey (N = 1095) which revealed that drivers subjectively perceive sexual contents in roadside advertising as distracting and dangerous. Study II was a modified version of the Attentional Network Test (N = 1063) which proved that in cognitive tasks reaction time increases in line with the sexual content of advertisements. Stu…

Refining the dual olfactory hypothesis: Pheromone reward and odour experience

2009

In rodents, sexual advertisement and gender recognition are mostly (if not exclusively) mediated by chemosignals. Specifically, there is ample evidence indicating that female mice are ‘innately’ attracted by male sexual pheromones that have critical non-volatile components and are detected by the vomeronasal organ. These pheromones can only get access to the vomeronasal organ by active pumping mechanisms that require close contact with the source of the stimulus (e.g. urine marks) during chemoinvestigation. We have hypothesised that male sexual pheromones are rewarding to female mice. Indeed, male-soiled bedding can be used as a reinforcer to induce conditioned place preference, provided co…

How does sexual attraction alter social interaction behavior? We examined the influence of sexual orientation on locomotor approach-avoidance behavior and interpersonal distance. We immersed androphilic and gynophilic male subjects into a virtual environment and presented various male and female virtual persons. In the first experiment, subjects took a step forward (approach) or backward (avoidance) in response to the sex of the virtual person. We measured reaction time, peak velocity, and step size, and obtained ratings of sexual attractiveness in every trial. In the second experiment, subjects had to approach the virtual person as if they were to engage in a social interaction. Here, we a…

Focal Lesions within the ventral striato-pallidum abolish attraction for male chemosignals in female mice

2014

In rodents, socio-sexual behaviour is largely mediated by chemosensory cues, some of which are rewarding stimuli. Female mice display an innate attraction towards male chemosignals, dependent on the vomeronasal system. This behaviour likely reflects the hedonic value of sexual chemosignals. The anteromedial aspect of the olfactory tubercle, along with its associated islands of Calleja, receives vomeronasal inputs and sexually-dimorphic vasopressinergic innervation. Thus, we hypothesised that this portion of the ventral striato-pallidum, known to be involved in reward processing, might be important for sexual odorant-guided behaviours. In this study, we demonstrate that lesions of this regio…

Digital contents as a tool to address research reproducibility crisis in psychology: A case study on sexual attraction under conditions of high arous…

2020

In the field of behavioral sciences, a crisis of the replicability of data took place. Among the reasons of the crisis, there is the difficulty of replicating some classical experimental settings and the lack of reproduced studies. Nowadays, digital contents might provide valuable opportunities to re-create specific environmental situations and manipulations in a safe and cost-saving way. The present study is a preliminary attempt to replicate the relationship between arousal manipulation and sexual attraction as it was assessed in the classical study by Dutton and Aron in 1974. Here, 30 male subjects will be randomly assigned to high or low arousal condition (induced with digital contents)…

Female Attraction Behaviour of Radio Tagged Polyterritorial Pied Flycatcher Males

1993

AbstractPolygynous mating is costly for pied flycatcher (Ficedula hypoleuca) females. Thus, females have a good reason to attempt to avoid mating with already mated polyterritorial males. One cue to disclose a male's mating status is his behaviour. The behaviour of polyterritorial and unmated males was studied by radio tagging that allows accurate recording of male movements. While attracting a secondary female polyterritorial males spent significantly less time on the secondary territory than did unmated males on their single territory. Polyterritorial males also tended to have lower song rates. When a female appeared on the secondary territory of polyterritorial males, they increased the …

The relationships between school belonging and students’ motivational, social-emotional, behavioural, and academic outcomes in secondary education: a…

2019

This meta-analytic review examines the relationships between students' sense of school belonging and students' motivational, social-emotional, behavioural, and academic functioning in secondary education. Moreover, it examines to what extent these relationships differ between different student groups (grade level, SES), measurement instruments, and region. The meta-analysis included 82 correlational studies, published in peer-reviewed journals between 2000 and 2018. Results revealed, on average, a small positive correlation with academic achievement, and small to moderate positive correlations with motivational outcomes such as mastery goal orientations; with social-emotional outcomes such …
