Article
Voice characteristics are important to communicate socially relevant information. Recent research has shown that individuals alter their voices depending on the context of social interactions and perceived characteristics of the audience, and this affects how they are perceived. Numerous studies have also shown that the presence of bodily odours ca...

The COVID-19 pandemic has increased negative emotions and decreased positive emotions globally. Left unchecked, these emotional changes might have a wide array of adverse impacts. To reduce negative emotions and increase positive emotions, we tested the effectiveness of reappraisal, an emotion-regulation strategy that modifies how one thinks about...

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...

Article
Full-text available
Body height is a life-history component. It involves important costs for its expression and maintenance, which may originate trade-offs on other costly components such as reproduction or immunity. Although previous evidence has supported the idea that human height could be a sexually selected trait, the explanatory mechanisms that underlie this sel...

Article
Objectives Facial averageness and sexual dimorphism are extensively studied attractiveness markers, which are viewed as possible indicators of biological quality. Both are complex morphological traits, and both can be easily assessed from frontal and lateral projection of a human face. Interestingly, examination of mutual relations between the fron...

Project
This project aims at identifying if there are, and which are, the acoustic variables of the voice, face morphometrics, and body odour, that are robustly associated with health indicators, function as signals of the individual's health status and genetic quality, and play an important role in the processes of selection of partners in humans. Specific goals: 1. To determine which facial morphometric and vocal acoustic characteristics correlate with individuals' health indicators. 2. To determine if there is a positive correlation between the robust expression of sexual characteristics, levels of T or E2, and health scores. 3. To determine if the body odour of healthy individuals is perceived as more attractive, masculine/feminine and healthy. 4. To determine if the perception of attractiveness and health in faces and voices is mediated by T and E2 levels of the stimulus. 5. To determine if the facial morphometric characteristics and vocal acoustics correlated with health indicators of the individuals, are preferably selected and perceived as more attractive. 6. To establish whether the most masculine or feminine average faces manipulated to express sexually dimorphic characteristics in a robust way, are perceived as more attractive and healthier.

Social effects of voice modulation.
Project
We are developing face manipulation process, that will potentially allow us to experimentally identify how cortical face processing is affected by relevant signals such as attractiveness, sex, and dominance.
