P erceiving others and oneself in terms of group identity influences the way people interact with others. When group memberships are salient, interactions are often guided by social roles (Eagly & Wood, 1999). To the extent that people rely on category-based, rather than individual-based, processing in their interaction, their perceptions will be influenced by group stereotypes and attitudes th...

Socially interactive robot needs the same behaviors and capabilities of human to be accepted as a member in human society. The environment, in which this robot should operate, is the human daily life. The interaction capabilities of current robots are still limited due to complex inter-human interaction system. Humans usually use different types of verbal and nonverbal cues in their communicati...

For many application areas, where a task is most naturally represented by talking or where standard input devices are difficult to use or not available at all, virtual characters can be well suited as an intuitive man-machineinterface due to their inherent ability to simulate verbal as well as nonverbal communicative behavior. This type of interface is made possible with the help of multimodal ...

The purpose of this study was to investigate the clinical usefulness of informal conversation as a tool for determining ability to communicate potential regardless of modality (verbal or nonverbal). Four individuals with aphasia (two non-fluent and two fluent) and four non-impaired individuals participated in this study. Selected segments of conversational discourse were analyzed for communicat...

Bilingual children regularly face communicative challenges when speakers switch languages. To cope with such challenges, children may attempt to discern a speaker's communicative intent, thereby heightening their sensitivity to nonverbal communicative cues. Two studies examined whether such communication breakdowns increase sensitivity to nonverbal cues. English-speaking monolingual (n = 64) an...

Our knowledge, how the brain controls and interrelates gesture and speech, is still limited. An interesting branch of the study has been the relationship between aphasia and nonverbal behaviour. The main feature of aphasia is the impairment of communication via natural language. One of the most significant questions is, whether gestures may substitute or compensate for speech in the event of sp...

BACKGROUND Disordered interpersonal communication can be a serious problem in schizophrenia. Recent advances in computer-based measures allow reliable and objective quantification of nonverbal behavior. Research using these novel measures has shown that objective amounts of body and head movement in patients with schizophrenia during social interactions are closely related to the symptom profil...

The functional outcome of schizophrenia is heterogeneous and markers of the course are missing. Functional outcome is associated with social cognition and negative symptoms. Gesture performance and nonverbal social perception are critically impaired in schizophrenia. Here, we tested whether gesture performance or nonverbal social perception could predict functional outcome and the ability to ad...

Conversation is the most natural and popular means for people to communicate with each other. Conversation is everywhere around us, and even though you may feel that making conversation is relatively effortless, a closer look shows that a tremendous amount of sophisticated interaction is involved in initiating and sustaining conversation. Figure 1.1 illustrates a normal conversation scene in ou...

BACKGROUND Nonverbal communication is a critical feature of successful social interaction and interpersonal rapport. Social exclusion is a feature of schizophrenia. This experimental study investigated if the undisclosed presence of a patient with schizophrenia in interaction changes nonverbal communication (ie, speaker gesture and listener nodding). METHOD 3D motion-capture techniques record...
