Studies have shown that videoconferences are an effective medium for facilitating communication between parties who are separated by distance. Furthermore, studies reveal that videoconferences are effective when used for distance learning, particularly when learners are engaged in complex collaborative learning tasks.

In the present research, performance-goals are conceived as a social tool for regulating interpers...

Welfare-oriented analyses of economic outcome measures such as income and wealth in general rest on the assumption of pooling and equal sharing of resources by all members of a given household. Examining the distribution of income and wealth within the household context is almost always hampered by the lack of individual level data.

Believability is a key issue for virtual agents. Most of the authors agree that emotional behavior and personality have a high impact on agents’ believability.
