Visual attention plays a central role in current theories of sexual information processing and is key to informing the use of eye-tracking techniques in the study of typical sexual preferences and more recently, in the study of atypical preferences …
Feeling and expressing love is at the core of romantic relationships, but individuals differ in their proclivity to worry about their relationships and/or avoid intimacy. Saying ‘I love you’ signals a commitment to a future with our romantic partner. …
The SARS-CoV-2 pandemic has imposed wide-spread negative impacts (economically, psychologically, neurologically and societally), and has changed daily behaviors on a global scale. Such impacts are more significant and pervasive in countries with …
Studies show that specific vocal modulations, akin to those of infant-directed speech and perhaps music, play a role in communicating intentions and mental states during human social interaction. Based on this, we propose a model for the evolution of …
One research line in criminal behavior studies 2D:4D ratio as predictor of aggression and violent behavior, given that there are sexually dimorphic behaviors associated with the influence of testosterone on brain organization. However, results have …
The human voice carries information about a vocaliser’s physical strength that listeners can perceive, and that may influence mate choice and intrasexual competition. Yet, reliable acoustic correlates of strength in human speech remain unclear. …
