The virtual world draws of the database information, on what would be the first image to show with respect to the mood of the avatar. The user scrolls through the avatar, from the initial point, which is the entrance of the maze to the exit. The virtual system verifies the coordinates the user has requested to move. The virtual world system in the database stores information about the environment that manifests itself at that time in the virtual world.
The managing agent extracted from the database information about the virtual world. The managing agent makes an inference of what is the appropriate emotion for the avatar. Anthropomorphic agent receives the message from managing agent. Anthropomorphic agent with the information received makes the inference, which dictates the image to show the avatar. The anthropomorphic inference agent is stored in the database. The user makes another movement of the avatar, using the arrow keys.
The virtual maze: A behavioural tool for measuring trust.
The virtual world detects movement the user makes. The virtual world pulls information from the database. The active virtual world to the agent broker. The broker agent extracts information about the virtual world through BD.
The broker agent sends a message to the managing agent with the information of the virtual world. For the case study developed a multi-agent system is represented graphically in a virtual world. The virtual world is a 3D maze. For the implementation of this system were used intelligent agents, GUI, database. The agents were implemented under the Jade environment, which were three agents, the manager agent, broker agent and anthropomorphic agent. The scenario consists of user interaction with the virtual environment, it is intended that there is a graphical representation in the handling of the system.
The user to display the image shows the representation of emotional state in which it is performed while interacting with the virtual environment. Figure 2, shows the virtual stage connected to the database and the user as part of the interaction of the system, where there is an intelligent system that allows different emotional states based on user interaction.
To solve the above rule it is proposes a multi-agent system in the interaction of a virtual world as shown in Figure 3 below. Figure 3 shows the virtual scenario now becomes the virtual domain, which interacts in the virtual environment.

The domain of actions, where the image of anger, sadness and joy is denoted by the Anthropomorphic Agent, will count with the help of two participants called: Broker Agent and Manager Agent. Within the domains that comprise the system are: The virtual domain has a virtual stage and a database. The Virtual Stage displays the information generated by the domain of the Shares. The domain contains three police actions, which are the following agents:. The connection between the virtual domain and domain of the Shares is made through the Interaction Domain. In the Domain of Interaction information is collected Virtual Stage, this information is used by agents of the Dominion of Actions to generate new data that will be reflected in the virtual domain.
Virtual Maze
The user starts the virtual tour inside the maze, helping through the arrow keys. The Virtual Domain sends information about what happens in the virtual scene through the Interaction Domain. Shares Mastery uses the information collected by the interaction domains, with this information generates new data that is sent through the Interaction Domain of the virtual domain to be displayed on the virtual stage. At system startup, the user takes the role of Manager Agent, which receives information from the state of the environment.
Within this domain are recorded the various changes of states, where states are presented:.
The interaction domains play the role of communication between the domain of the Emotions and the virtual domain. Use appropriate language for the interaction of the domains. One advantage of VR technology in neuroscientific research is that participants can undergo elaborate tests on brain activity while kept sufficiently stationary, as they experience virtual scenarios that elicit very real responses. Also, the high degree of control that researchers have over the creation and manipulation of virtual environments is incomparable to real-world testing environments.
VR-based experiments provide a more engaging alternative to passive experimental content such as video or written recordings of sample scenarios. Finally, VR environments circumvent many ethical constraints Doucet et al. One of the ways through which researchers attempt to unfurl the mysteries of the human mind is through comparative psychology and neuroscience, a field of study which deals with in-depth research on animal behavior.
Background and History of VR Technology
The human brain and the brain of animals such as rodents and monkeys share many similarities, and observing them in different scenarios has contributed greatly to what we know of how the nervous system functions today. However, VR technology now presents different applications of curating human versions of classical animal research of different fields such as spatial navigation and social interaction, as well as the exploration of uniquely human activities such as driving. A huge domain of animal research pertains to spatial cognition and navigation , which usually involve putting rats or mice in mazes.
But, with the advent of VR technology and its compatibility with functional imaging techniques Bohil et al. In a study by Bohbot et al.

To examine allocentric learning, the participants were made to explore a virtual park, and to examine egocentric learning; they were made to solve a virtual maze. The conventional rodent paradigms of social interaction are in use for ages. VR technology also allows for the observation of brain activity during naturalistic scenarios of face-to-face social interaction between two or more individuals Bohil et al. Therefore, having a virtual self can be a great tool for social neuroscience—a field of study that involves looking at which specific brain regions are activated in certain social scenarios, such as in the interpretation of face and eye movements.
Hyperscanning, meanwhile, is a VR-based methodology for observing reactions of multiple participants in shared social situations in the virtual world Montague et al. This method links magnetic resonance scanners and brain imaging technology in synchrony with the behavioral interaction of participants put in social situations, such as sharing a game of deception. The reason why this ground-breaking but disputable study on behavior cannot be replicated is its morally-questionable nature, wherein participants were asked to deliver electric shocks to strangers at the command of an authority figure.
Advancements in social neuroscience have also contributed greatly to both understanding and treating social deficits that occur in autism spectrum disorders, through evidence-based interventions. In Kandalaft et al. In addition, virtual rehabilitation also has applications in the diagnosis and assessment of social avoidance in the context of social anxiety disorders, specifically through eye-tracking systems during public speaking exercises in front of virtual scenes Grillon et al.
