Testosterone and Fathers’ Parenting Unraveled: Links with the Quantity and Quality of Father-Child InteractionsAdaptive Human Behavior and Physiology - Tập 5 - Trang 297-316 - 2019

Individual differences in quality of father involvement in caregiving might in part be explained by fathers’ testosterone (T) levels. We examined the links between fathers’ (n = 32) salivary T levels, amount of time spent with their child (12–30 months of age), type of father-child interaction, and fathers’ sensitivity. During two home visits, video observations of father-child interactions were c...... hiện toàn bộ
Gender and Context-Specific Effects of Vocal Dominance and Trustworthiness on Leadership DecisionsAdaptive Human Behavior and Physiology - Tập 8 - Trang 538-556 - 2022
Christoph Schild, Elisa Braunsdorf, Katharina Steffens, Franka Pott, Julia Stern
The evolutionary-contingency hypothesis, which suggests that preferences for leaders are context-dependent, has found relatively consistent support from research investigating leadership decisions based on facial pictures. Here, we test whether these results transfer to leadership decisions based on voice recordings. We examined how dominance and trustworthiness perceptions relate to leadership de...... hiện toàn bộ
Self-perceived Mate Value is Predicted by Biological and self-reported Indices of Health in Young AdultsAdaptive Human Behavior and Physiology - Tập 9 - Trang 54-71 - 2023

Immunocompetence can influence an organism’s reproductive fitness, and thus presumably their desirability as a mate (i.e., mate value). In humans, the link between immunocompetence and mate value has found circumstantial support by way of both expressed mate preferences for healthy partners, and via preferences for attractive phenotypes that are ostensibly linked to immune functioning. We examined...... hiện toàn bộ
Heart Rate Variability Differences among Participants with Different Levels of Self-Criticism during Exposure to a Guided ImageryAdaptive Human Behavior and Physiology - Tập 5 - Trang 371-381 - 2019
Júlia Halamová, Martin Kanovský, Jana Koróniová
Our goal was to investigate the heart rate variability differences among participants with different levels of self-criticism during exposure to self-critical, self-protective, and self-compassionate guided imagery. Convenience sample of 89 psychology students was collected with the provision of course credits. The participants underwent measurement of heart rate variability during the guided imag...... hiện toàn bộ
Cross-Cultural Variation in Men’s BeardednessAdaptive Human Behavior and Physiology - Tập 6 - Trang 490-500 - 2020
Barnaby J. W. Dixson, Anthony J. Lee
To test whether cross-cultural variation in men’s facial hair conforms to patterns predicted by processes of inter-sexual and intra-sexual selection. Data were taken from the PEW Research Center’s World’s Muslims’ project that collected information from 14,032 men from 25 countries. An Independent Factor Analysis was used to analyse how suites of demographic factors predict men’s beardedness. Anal...... hiện toàn bộ
Are Sexual Desire and Sociosexual Orientation Related to Men’s Salivary Steroid Hormones?Adaptive Human Behavior and Physiology - Tập 6 - Trang 447-466 - 2020

Although it is widely assumed that men’s sexual desire and interest in casual sex (i.e., sociosexual orientation) are linked to steroid hormone levels, evidence for such associations is mixed. We tested for both longitudinal and cross-sectional relationships between salivary testosterone, cortisol, reported sexual desire and sociosexuality in a sample of 61 young adult men, each of whom was tested...... hiện toàn bộ
Effects of Sexually Dimorphic Shape Cues on Neurophysiological Correlates of Women’s Face ProcessingAdaptive Human Behavior and Physiology - Tập 3 - Trang 337-350 - 2017

Sexual dimorphism (i.e., masculinity in males and femininity in females) is known to affect social perceptions that are important for both mate choice and intrasexual competition, such as attractiveness and dominance. Little is known, however, about the neurophysiological underpinnings mediating sexual dimorphism’s effects on face processing. Here we investigate the neurological correlates of proc...... hiện toàn bộ
