Abstract. This paper examines the interaction of verbal and nonverbal information for conveying social dominance in intelligent virtual agents (IVAs). We expect expressing social dominance to be useful in applications related to persuasion and motivation; here we simply test whether we can affect users' perceptions of social dominance using procedurally generated conversational behavior. Our results replicate previous results showing that gaze behaviors affect dominance perceptions, as well as providing new results showing that, in our experiments, the linguistic expression of disagreeableness has a significant effect on dominance perceptions, but that extraversion does not.
Antipsychotic drugs have made a significant contribution to the treatment of schizophrenia but the older drugs in particular have significant side-effects. The newer atypical drugs are effective for the treatment of both positive and negative symptoms and they also have significantly fewer serious side-effects. However, these drugs are considerably more expensive that the older drugs and this has generated intense debate about their cost effectiveness. There is now good evidence that when all factors are taken into consideration the atypical drugs are both cost effective and improve the quality of life of patients with schizophrenia. Despite the importance of these drugs there is widespread variation in their use and a national consensus on this important issue is long overdue.
