Much work on communication and joint action conceptualizes interaction as a dynamical system. Under this view, dynamic properties of interaction should be shaped by the context in which the interaction is taking place. Here we explore interpersonal movement coordination or synchrony-the degree to which individuals move in similar ways over time-as one such context-sensitive property. Studies of...

Loss of verbal language production makes people with dementia appear unreachable. We previously presented a case study applying nonverbal communication techniques with a lady with dementia who could no longer speak, which we termed Adaptive Interaction. The current small-n study examines the applicability of Adaptive Interaction as a general tool for uncovering the communication repertoires of ...

Human ethology, which was established on the basis of classical zooethology, can be an inspirational contribution to the study of human behavior. The study of behavior in natural conditions is stimulating as well as the primary interest of ethologists in such behavioral patterns showing evolutionary success and benefits and which are called inborn or innate. The extensive area of human behavior...

We conducted a brief computer-based assessment involving choices of concurrently presented arithmetic problems associated with competing reinforcer dimensions to assess impulsivity (choices controlled primarily by reinforcer immediacy) as well as the relative influence of other dimensions (reinforcer rate, quality, and response effort), with 58 children. Results were compared for children with ...

Social and policy interventions over the last half-century have achieved laudable reductions in blatant discrimination. Yet members of devalued social groups continue to face subtle discrimination. In this article, we argue that decades of anti-discrimination interventions have failed to eliminate intergroup bias because such bias is contagious. We present a model of bias contagion in which int...

Producing high-quality mammograms requires excellent technical skills along with exemplary communication. Mammographers must be able to address differences in patients' mental states, body habitus, and physical ability to obtain an optimal examination. In addition, every mammographer must practice consistently with patient safety, care, and satisfaction in mind. This article discusses verbal an...

This paper addresses fundamental research problems concerning the implementation of nonverbal communication channels in so-called conversational interfaces: As a solution to these problems a new methodology is introduced that makes possible the generation, systematic variation and experimental evaluation of nonverbally interacting interface agents in different task contexts. A taxonomy of resea...
