Social Priming Increases Nonverbal Expressive Behaviors in Schizophrenia

Social Priming Increases Nonverbal Expressive Behaviors in Schizophrenia

Semantic priming tasks are classically used to influence and implicitly promote target behaviors. Recently, several studies have demonstrated that prosocial semantic priming modulated feelings of social affiliation. The main aim of this study was to determine whether inducing feelings of social affiliation using priming tasks could modulate nonverbal social behaviors in schizophrenia. We used t...

Nonverbal Communication in Virtual Worlds: Understanding and Designing Expressive Characters

Inhaled oxytocin increases positive social behaviors in newborn macaques.

Early caregiver-infant interactions are critical for infants' socioemotional and cognitive development. Several hormones and neuromodulators, including oxytocin, affect these interactions. Exogenous oxytocin promotes social behaviors in several species, including human and nonhuman primates. Although exogenous oxytocin increases social function in adults--including expression recognition and af...

Expressive Behaviors for Virtual Worlds

A person's behavior provides signi cant information about their emotional state, attitudes, and attention. Our goal is to create virtual humans that convey such information to people while interacting with them in virtual worlds. The virtual humans must respond dynamically to the events surrounding them, which are fundamentally in uenced by users' actions, while providing an illusion of human-l...

Annotation of Utterances for Conversational Nonverbal Behaviors

Nonverbal behaviors play an important role in communication for both humans and social robots. However, adding contextually appropriate animations by hand is time consuming and does not scale well. Previous researchers have developed automated systems for inserting animations based on utterance text, yet these systems lack human understanding of social context and are still being improved. This...
