Responsiveness and communication medium in dyadic interactions

Pairs of subjects discussed a case history in a face-to-face situation, or via closed-circuit TV, telephone, or written messages. In addition to these true conversations, other subjects engaged in pseudoconversations in which they were yoked to one member of an interacting pair. Subjects tested with responsive partners rated them and the discussion more favorably and showed more opinion change than subjects with unresponsive pseudopartners, while communication medium had no effect.
