Perceiving Others as Intrinsically or Extrinsically Motivated: Effects on Expectancy Formation and Task Engagement

In Study 1, participants who read about an extrinsically motivated target expected that task engagement would be less enjoyable and associated with less positive affect and that there would be poorer quality of interpersonal relations, compared with participants reading about an intrinsically motivated target. These effects were reversed when additional information disconfirmed initial perceptions of the target's motivation. In Study 2, participants who were taught a skill by an extrinsically motivated (paid) target reported lower interest in learning and lower task enjoyment than those taught by an intrinsically motivated (volunteer) target, despite receiving identical lessons and learning to the same criterion level. Lower levels of interest, task enjoyment, and positive mood "infected" a second learner when the first participant attempted to teach him or her the same skill. Results support a model linking social perception, expectancy formation, and motivational orientations toward activities.
