compares the face-to-face to audio-only communication and the effect on
Studies in this paper include :
There are some interesting question discuessed in the class, such as :

- Conformity and Anonymity.
- Studies of media differences in the mechanics of interaction.
- Studies of information transmission.
- Effects of communication in bargaining games.
- Communication modality and attitude change.
- Problem solving.
- Miscellaneous media comparison.
- The "One-way mirror" experiment, for the "presence of others" effect.
- Teletype vs. face-to-face communication, teletype was found to
be the most effective mode.
- Better recall in Audio-only conditions.
- The "painful shocks" experiment, a proximity situation is observed to
have hugh effect on the test subjects. Also, interestingly, if the
experimenter was not physically present, the test subjects tend to
cheat or lie to the distant experimenter about their actions.
- "Risky shift" situation. Is it caused by the feeling that some others
are supporting me, or does it become a shared responsibility after
a group discussion.
- The less-rich media are more efficient, (What's the
definition of efficiency here?) from the "manipulated medium of
communication" test in p174.
