The human ability to follow speech gestures through the visual modality is a core component of speech perception. Remarkably, speech can be perceived not only by the ear and by the eye but also by the hand, with speech gestures felt from manual tactile contact with the speaker’s face. In the present study, early crossmodal interactions were investigated by comparing early auditory evoked potent...

Many social phenomena involve a set of dyadic relations among agents whose actions may be dependent. Although individualistic approaches have frequently been applied to analyze social processes, these are not generally concerned with dyadic relations, nor do they deal with dependency. This article describes a mathematical procedure for analyzing dyadic interactions in a social system. The propo...

Katz and Pavlovic recently proposed a dyadic model of the Euler equations for which they proved finite time blow-up in the H3/2+ǫ Sobolev norm. It is shown that their model can be reduced to the dyadic inviscid Burgers equation where nonlinear interactions are restricted to dyadic wavenumbers. The inviscid Burgers equation exhibits finite time blow-up in Hα, for α ≥ 1/2, but its dyadic restrict...

The current study examined whether dyadic synchrony of father-child and mother-child interactions in a playful context were associated with attachment organization in preschool children. One hundred seven children (48 boys, Mage = 46.67 months, SD = 8.57) and their mothers and fathers (counterbalanced order of lab visits) participated in a playful interaction without toys (Laughing Task procedu...

There is a growing consensus that a fuller understanding of social cognition depends on more systematic studies of real-time social interaction. Such studies require methods that can deal with the complex dynamics taking place at multiple interdependent temporal and spatial scales, spanning sub-personal, personal, and dyadic levels of analysis. We demonstrate the value of adopting an extended m...

objective: marital adjustment has been regarded as an important issue in chronic illnesses. some studies have addressed the effect of viral hepatitis on patients' spouses but there is still limited information on the topic. this study has compared marital adjustment in patients suffering from different stages of viral hepatitis with that of a healthy population. methods: in a cross-sectional st...

The nature of the dynamics of nonverbal interactions is of considerable interest to the study of human communication and future human-computer interaction. Facial expressions constitute an important source of nonverbal social signals. Whereas most studies have focused on the facial expressions of isolated individuals, the aim of this study is to explore the coupling dynamics of facial expressio...

Using the Electronically Activated Recorder (EAR), a new methodology for sampling behavioral data in naturalistic settings, we tracked the social lives of 11 people by recording 30-s snippets of ambient sounds in their environment approximately every 12 min. Participants wore the EAR continuously for 10 days from September 11, 2001. Pre-September 11 baseline data were available for all particip...
