The present study aimed to explore dynamic and interactive aspects of cosleep in heterosexual couples. The sample consisted of eight young healthy adults who belonged to four heterosexual couples with a good relationship quality and a history of cosleeping. All individuals underwent simultaneous polysomnography in a sleep laboratory for four nights in which they slept individually and with thei...

System behavior studies, aiming to understand intrinsic features, have been conducted in several science domains. During the study and analysis of a system, one of the main difficulties is the presence of stochastic and deterministic components. When such components are not correctly analyzed, the accuracy of applied models tends to reduce. Therefore, before modeling a system, one needs to unde...

Often, a relatively small number of trials suffices to enhance one’s task-specific perceptual capability. In the present experiment, fast perceptual learning was investigated with respect to the perception of the heights or widths of wielded nonvisible rectangular objects. In that haptic perceptual task, inertial differences (mass and moments of inertia) are the basis for perceived size differe...

We introduce our methodological study with a short review of the main literature on embodied language, including some recent studies in neuroscience. We investigated this component of natural language using Recurrence Quantification Analysis (RQA). RQA is a relatively new statistical methodology, particularly effective in complex systems. RQA provided a reliable quantitative description of recu...
