Introduction
My current research interests are focused on interactive synchronization and the role of self-touching behaviors in the social interactions. I am also interested in the origins and evolution of language.

The aim of the study was to investigate the response of testosterone and cortisol to sprint interval exercises (SIEs) and to determine the role of dominance. The experiment was conducted in a group of 96 men, divided into endurance-training, strength-training, and non-training groups. Participants performed SIEs consisting of 5 × 10-s all-out bouts...

The male beard is one of the most visually salient and sexually dimorphic traits and a hypothesized potential marker of other traits, such as dominance, masculinity, social status, and self-confidence. However, as men can easily alter their facial hair, beards may provide unreliable information about the beard owner’s characteristics. Here, we exam...
Article
Full-text available
Research has demonstrated that increases in testosterone (T) concentration can affect the expression of behaviours and preferences that are typical of high mating effort. However, little research has considered whether such T increases affect mating strategy more generally and whether this is achievable using a physical intervention. In this pilot...
Article
Human male height is one of the most conspicuous sexually dimorphic, phenotypic characteristics that affect how men are perceived both by men and women, impacting mate selection and intra-sexual competition. Testosterone is a key hormone linked to morphological masculinity and advantage in intra-sexual competition. To date, there have been limited...
Article
Full-text available
The digit ratio (2D:4D) is said to be a potential marker of exposure to prenatal sex steroids. Some studies suggest that the 2D:4D is also linked with the testosterone response to challenging situations due to organizational effect of prenatal hormonal milieu on adult endocrine functioning. However, up to date, there were only four studies (conduct...
Article

Turn-taking – the coordinated and efficient transition between the roles of sender and receiver in communication – is a fundamental property of conversational interaction. The turn-taking mechanism depends on a variety of linguistic factors related to syntax, semantics and prosody, which have recently been subject to vigorous research. This contras...
Presentation
Full-text available
Self-touching behaviors – such as scratching one’s cheek or rubbing one’s nose – are typically accounted for in terms of self-regulation, such as coping with negative affect (e.g. Ekman and Friesen 1969) or disruptions of attention (e.g.), but there are also lines of research indicating that self-touching plays a supportive role in the dynamics of...
Article
In everyday circumstances, humans use a variety of cues to draw rich inferences about the nature of interaction. Among these, we focus on sequences of self-regulatory movements, such as touching behaviours and postural changes, that have long been related to interpersonal coordination understood both in terms of mimicry and synchrony. So far, there...

The age-old debate between the proponents of the gesture-first and speech-first positions has returned to occupy a central place in current language evolution theorizing. The gestural scenarios, suffering from the problem known as “modality transition” (why a gestural system would have changed into a predominantly spoken system), frequently appeal...

In our paper we review the gestural primacy hypotheses in languageevolution, starting with the discussion of the historical advocates of this ap-proach and concluding with the contemporary arguments, derived from empiricalresearch in various fields of study. Assessing the strengths and weaknesses ofthe gestural scenarios we point to their main prob...
Conference Paper
Full-text available
The so-called gestural theories of language origins have remained a central focus of language evolution research for at least a decade. Despite important differences, their varieties underscore the significance of visual, as opposed to vocal, channel of signal transmission. However, language is predominantly spoken; that is (excluding recent techno...

The aim of the study is to determine how much visual attention is paid to self-touching behaviours and gesticulations during narration.
