Social Attitudes: Investigations with Agent Simulations Using Webots
نویسندگان
چکیده
This article presents a multiagent simulation environment for studying agents' sociopolitical attitudes. It departs from a previously proposed concept of agents with sociopolitical attitudes, a high-level theoretical and conceptual model proposed by Petric et al. (2002) that was intended for conversational agents. In contrast, our work pursues a bottom-up simulation philosophy where attitudes are grounded in sensory-motor behaviour of spatially distributed autonomous agents, modelled in Webots simulation software. The original model was extended by defining an agent's socio-political type by means of weighting the three components found in the Petric et al. (2002) model (neo-liberal, alternative and fundamentalist), thus allowing the creation of mixed socio-political types. Also, in the simulations performed, issues were modelled as agents with variable levels of importance. Moreover, we introduced inter-agent communication capable of causing changes in socio-political types. Results are presented and discussed with respect to the initial research questions. According to our experimental results the following parameters did not have any significant impact on the simulation outcomes: initial physical position and orientation of the agents, positions of the issues, the issues' dynamics, and inter-agent communication. Experiments with different initial agent types showed that agents with indeterminate socio-political types tended to change to neo-liberal, alternative or fundamentalist agents. We conclude by proposing future extensions of the model. Our work is related to a trend in the Artificial Intelligence community which is not primarily task or problem-solving oriented, but rather focuses on the study of the embodied and situated nature of social behaviour in humans.

Modeling the emergence of shared atti- tudes from group dynamics using an agent-based model of social comparison theory
We propose a novel agent-based implementation of Festingers’ Social Comparison Theory (SCT). The Social Comparison Model (SCM) consists of connectionist networks that simulate agent-level social comparison processes. Agent networks are combined into a adaptive network structure that is shaped by social comparisons between individual agents. Simulations show how the SCM produces behavior consist...
متن کاملAn Agent-Based Model to Explore Game Setting Effects on Attitude Change During a Role Playing Game Session
Role playing games (RPGs) can be used as participatory simulation methods for environmental management. However, researchers in the field need to be aware of the influence of the game settings on participants' behavioural patterns and attitudes, before fine tuning the design and use of their games. We developed an agent-based model (CauxAttitude) to assess the framing induced by the conditions ...
متن کاملInformation Fields in Organization Modeling Using an EDA Multi-agent Architecture
The EDA model (Epistemic-Deontic-Axiological) is an agent model based on the social psychology theoretical classification of norms and corresponding attitudes: Ontological, Epistemic, Deontic and Axiological. EDA agents are situated in normative information fields, and are described in terms of the basic attitudes aforementioned. Information fields are used as the basis for coordinating an orga...
متن کاملExpressing social attitudes in virtual agents for social training games
The use of virtual agents in social coaching has increased rapidly in the last decade. In order to train the user in different situations than can occur in real life, the virtual agent should be able to express different social attitudes. In this paper, we propose a model of social attitudes that enables a virtual agent to reason on the appropriate social attitude to express during the interact...
