Over the past 10 years, Oosterhof and Todorov’s valence–dominance model has emerged as the most prominent account of how people evaluate faces on social dimensions. In this model, two dimensions (valence and dominance) underpin social judgements of faces. Because this model has primarily been developed and tested in Western regions, it is unclear w...

Over the last ten years, Oosterhof and Todorov’s valence-dominance model has emerged as the most prominent account of how people evaluate faces on social dimensions. In this model, two dimensions (valence and dominance) underpin social judgments of faces. Because this model has primarily been developed and tested in Western regions, it is unclear w...

Individuals vary in their intrasexual competitiveness attitude, i.e., an important variable reflecting the potential threat or the extent to which one perceives other individuals of the same sex as social or mating rivals. In this study, we investigated the relationship between self-perceived mate value, a construct usually linked to intersexual se...

Bodily attractiveness is an important component of mate value. Musculature-a crucial component of men's bodily attractiveness-provides women with probabilistic information regarding a potential mate's quality. Overall musculature is comprised of several muscle groups, each of which varies in information value; different muscles should be weighted d...

Prosocial third-party punishment (3PP) is a punitive behavior against antisocial individuals, which might explain extended cooperativeness in humans. 3PP shows sexual dimorphism, being more frequent in men than in women. We studied whether sexually dimorphic features related to sexual hormones during development (facial dimorphism and 2D:4D) influe...

In the present paper, we study how the morphological features related to developmental physiology of other participants influence the decision to cooperate in a social dilemma. To that end, we let a large sample of men play a prisoner's dilemma game, both anonymously and against a series of counterparts whose photographs were shown. We focus on thr...

Dishonesty in communication has important economic implications. The standing literature have shown that lying is less pervasive than predicted by standard theory. We explore whether biology can help to explain this behavior. In particular, we study whether masculinity, assessed by exposure to testosterone during key phases of brain development, is...

One of the relevant personal differences that has been poorly studied (beyond bullying) in its relationship with aggressiveness in adolescents is “quality of life.” In the present study, we explored both the sex differences and the relationship between aggressiveness (from the Buss and Perry Aggression Questionnaire) and quality of life (from the K...

Durante los últimos años en Chile se ha detectado una masificación en el uso de anticonceptivos orales. Sin embargo, en Chile y al igual que en casi todos los países latinoamericanos prácticamente no se han investigado sus implicancias sobre la conducta humana. Específicamente, este estudio evaluó el impacto del uso de estos anticonceptivos sobre l...

In this study, we applied an evolutionary perspective to analyze the relationship between aggressiveness, academic performance, and sociality in a population of 528 adolescents of both sexes. In men, we expect physical aggression and sociality to be negative predictors of academic performance. However, in women, physical aggression would be a negat...

Complexity in the processing of the Amyloid Precursor Protein, which generates a mixture of βamyloid peptides, lies beneath the difficulty in understanding the etiology of Alzheimer’s disease. Moreover, whether Aβ peptides have any physiological role in neurons is an unresolved question. By expressing single, defined Aβ peptides in Drosophila, spec...

Oral contraceptives, also known as birth control pills (PAs from now on), have been available on the world market for five decades. At present, the use of PA is massifier worldwide, being consum ed by more than 100 million women on the planet. In recent years, in Latin America has been detected a dramatic increase in the use of oral contra ceptives...

Several studies have demonstrated the relationship between handgrip strength (HGS) and fighting ability in men, which is a relevant trait for intrasexual competition to increase the probability of obtaining a mate. However, few studies have determined a relationship between fighting ability and men’s self-perceived capacity to find, attract and ret...

Prior research has suggested that men overestimate women’s sexual intentions. However, the bulk of the data supporting this view comes from participants from the USA. Here, we report three attempts to replicate this effect in samples from Chile, Spain, and France. While there was some evidence of overestimation of sexual intent by men on the aggreg...

Attractiveness plays an important role in social exchange and in the ability to attract potential mates, especially for women. Several facial traits have been described as reliable indicators of attractiveness in women, but very few studies consider the influence of several measurements simultaneously. In addition, most studies consider just one of...

Recent research has explored the relationship between facial masculinity, human male behaviour and males' perceived features (i.e. attractiveness). The methods of measurement of facial masculinity employed in the literature are quite diverse. In the present paper, we use several methods of measuring facial masculinity to study the effect of this fe...

Facial Fluctuating Asymmetry (FFA) is proposed as an indicator of genetic quality in human beings. There is evidence that support the notion that attractiveness is negatively associated to FFA. However, an important number of these studies have been carried out from the perspective of men´s ratings on female faces, and without considering if hormon...

This study aims to test whether two morphometric characteristics, the second to fourth finger length ratio (2D:4D index) and the facial width-to-height ratio (FWH index), which reflects the degree of facial masculinization, are related to aggression in adolescents of both sexes. Previous studies have proposed that the 2D:4D index (a trait related t...

A recent and controversial hypothesis suggests the presence of an oestrus phase in women as in other mammals. This implies that women at their optimal fertility point of the menstrual cycle exhibit behaviors focused to maximize the genetic quality of their offspring. Several studies support this hypothesis, finding that women in the fertile phase t...

Sensory cilia are often encapsulated by an extracellular matrix (ECM). In Caenorhabditis elegans, Drosophila melanogaster, and vertebrates, this ECM is thought to be directly involved in ciliary mechanosensing by coupling external forces to the ciliary membrane. Drosophila mechano- and chemosensory cilia are both associated with an ECM, indicating...

El uso de anticonceptivos orales se encuentra masificado en la población Chilena (MINSAL e INE, 2002). Estudios efectuados en población anglosajona han encontrado diferencias sociosexuales entre mujeres que consumen anticonceptivos orales y aquellas que no lo hacen. Estas diferencias apuntan a un mayor número de parejas sexuales (Liale et al., 2002...

A number of transcription factors that are expressed within most, if not all, embryonic neuroblast (NB) lineages participate in neural subtype specification. Some have been extensively studied in several NB lineages (e.g. components of the temporal gene cascade) whereas others only within specific NB lineages. To what extent they function in other...

The present paper analyzes the extent to which attractiveness-related variables affect cooperative behavior in women. Cooperativeness is evaluated through a Prisoner’s Dilemma Game (PDG). We consider several morphometric variables related to attractiveness: Fluctuating Asymmetry (FA),Waist-Hip Ratio (WHR), Body Mass Index (BMI) and Facial Femininit...

Biological features and social preferences have been studied separately as factors influencing human strategic behaviour. We run two studies in order to explore the interplay between these two sets of factors. In the first study, we investigate to what extent social preferences may have some biological underpinnings. We use simple one-shot distribu...

Alzehimer´s Disease is a neurodegenerative disorder characterized by early synaptic and late neuronal loss. It is generally accepted that the amyloid Aβ peptide is the primary cause of the disease, although the specific mechanisms that underlie its synaptotoxic and neurotoxic effects are not well understood. To better understand the role of the dif...

Recent research suggests that evolutionary selection pressures have shaped mental mechanisms to be able to assess one's own and other's physical strength, fighting ability, and aggressiveness. According to the recalibrational theory, anger may be linked to fighting ability and serve as a bargaining mechanism to improve welfare obtained in social co...

Intrasexual competition is often characterized by the struggle for sexual partners. Men’s competitive behavior typically includes physically aggressive acts or anger, whereas women tend to disgrace their rivals via derogation. Fluctuating asymmetry (FA), a measure of developmental instability and health, has been reported to negatively correlate wi...

HCN channels are becoming pharmacological targets mainly in cardiac diseases. But apart from their well-known role in heart pacemaking, these channels are widely expressed in the nervous system where they contribute to the neuron firing pattern. Consequently, abolishing Ih current might have detrimental consequences in a big repertoire of behaviora...

Effect of DmIh mutation on Dopamine cycling in LD and DD conditions. Two way ANOVA on dopamine datapoints was performed for both conditions (LD and DD) to assess the effect of genotype (control or DmIh mutant) and circadian time (ZT/CT). In L∶D, both genotype and ZT significantly affect dopamine levels. Dopamine levels vary with ZT in both genotype...

Comparison of Dopamine cycling in LD and DD conditions in control flies. Two way ANOVA on dopamine datapoints was performed to assess the effect of circadian time (ZT/CT) and light condition (LD or DD). A two-way ANOVA including both factors and their interaction is significant (F13,42 = 4.760; p<0.001). Both factors have a significant effect, and...

In this study, we examined the influence of female size on mating success in Drosophila melanogaster. The results that were obtained from experiments performed in mating chambers allowed us to confirm the results of previous studies, demonstrating higher mating success of larger D. melanogaster males, and to conclude that female size also affects m...

Recent research has analyzed how individual characteristics, like the exposure to different hormones and symmetry, affect decision-making and strategic behaviour. The present article investigates the effect of symmetry, of exposure to testosterone (T) in utero and during puberty and of current T on cooperation in a Prisoners' Dilemma Game (PDG). T...

One of the most widely studied phenomena in the establishment of neuronal identity is the determination of neurosecretory phenotype, in which cell-type-specific combinatorial codes direct distinct neurotransmitter or neuropeptide selection. However, neuronal types from divergent lineages may adopt the same neurosecretory phenotype, and it is unclea...

A growing number of human neurodegenerative diseases result from the expansion of a glutamine repeat in the protein that causes the disease. Spinocerebellar ataxia type 1 (SCA1) is one such disease-caused by expansion of a polyglutamine tract in the protein ataxin-1. To elucidate the genetic pathways and molecular mechanisms underlying neuronal deg...
