objectives: the aim of present study was to evaluate some effects of crinum zeylanicum (c. zeylanicum) on central nervous system. materials and methods: c. zeylanicum methanolic bulb extract (250-1000 mg/kg orally), 2 mg chlorpromazine and 4 mg diazepam /kg body weight intraperitoneally respectively were tested in mice using irwin test, pentobarbitone-induced sleep test, spontaneous motor activ...

Existing theories of stereotype change have often made use of categorisation principles in order to provide qualitative explanations for both the revision and maintenance of stereotypical beliefs. The present paper examines the quantitative methods underlying these explanations, contrasting both rational and heuristic models of stereotype change using participant data and model fits. In a compa...

Agents joining multi-agent systems (MAS) face two significant problems: they do not know who to trust and others do not know if they are trustworthy. Our contribution extends trust and stereotype approaches to use a comparison of agents’ observable features, called tags, as an initial indication of expected behaviour. The results show an improvement in agents’ rewards in the early stages of the...

Physical attractiveness is an important cue for social interaction. Psychology studies have long shown that physical attractiveness can elicit positive personality attributions as well as positive behaviour towards other people. This effect is explained by the attractiveness stereotype. In this paper, we investigate whether this stereotype apply to the interaction with virtual agents. We report...

In real-world environments, cooperation often emerges amongst agents who are observably similar. Estimating the expected behaviour of another agent is a challenging problem, particularly for new agents who have little or no experience of others. In this paper, we show how observable features can be used to find similar, and hence cooperative, partners. Our contribution extends trust and stereot...

OBJECTIVE The experience of stereotype threat (where the prospect of conforming to a stereotype, or of being treated in terms of it, becomes self-threatening) affects members of social groups about whom devaluing stereotypes exist. Although a widely endorsed stereotype of schizophrenia concerns social skill impairment, it is unclear whether the experience of stereotype threat impacts social fun...

Social perception involves the development of an attitude towards another person or group of persons. A stereotype is an attitude towards a person or group on the basis of some physical characteristic or physical fact. A stereotype is an example of an implicit personality theory. Such theories attribute internal properties to a person, such as character traits, on the basis of external properti...
