An Early Media Equation Experiment


Subjects were Stanford computer science students; some explicitly stated they would never be polite to a computer.

Computers were plain black Next boxes, communicating with lines of text only.

In a laboratory, a "teacher" computer provided tutoring. Then students took a test on the material. All students were given the same (bogus) score.

In various ways, students were asked for their opinion of the computer "teacher".

When they were in the same room with the "teacher", the students were extremely polite and rated their "teacher" highly. When they were in a different room they were much more critical of the "teacher".

This effect only occurred when the students' minds were occupied with the bogus task, not thinking about the social interaction.






Many variations checked the effect on effect of praise, gender, type of directions, whether or not the teacher and tester computers were combined, and so on. They replicated a number of well-documented social science findings, substituting a computer or TV for some of the social actors.

If you're interested in this I strongly urge you to read the research yourself. Or invite the principals to give a talk at your institution.
