Social style is measured along the two dimensions of assertiveness and responsiveness.
These dimensions include versatility, trust, credibility, power, attraction and similarity. These differences will reflect those found for human-human interaction. In cases where the social style of the computer program and the user are similar, the program will receive more favorable ratings than in cases where the social style of the program differs from the social style of the user. Subjects will then perform a search task using one of four different versions of the same program, each of which will exhibit a different social style. After finishing the task, they will fill out a questionnaire rating the computer program on social style and person perception variables.
