Student E s delivered persuasive communications against U.S. involvement in S.E. Asis to community residents in the residents' homes. The S s received either a written communication (a pamphlet), or a verbal communication (a talk with a student E), or, on successive occasions, both. A control group received neither communication. Later all the Ss were approached by other student Es with a relevant opinion inventory. At this time they were also offered a choice of contrasting petitions to sign.

The attitude measure reflected no difference as a result of the written communication, and a negative persuasion effect for the verbal communication. Also Ss signed significantly fewer petitions, whether pro or con, after the vcrbal communication. The pragmatic implications of these results are discussed as they relate to student canvassers in the community.
