Recall that Harold Kelley (1950) told some college students that their guest instructor was a warm person, and others that he was a cold person.
 
  Students who were told that the guest instructor was a warm person evaluated him more positively and participated more in class discussion than did students who were told that he was cold. These results support the idea that schemas are
 
   a. universal.
   b. impossible to modify.
   c. especially influential when we encounter ambiguous information.
   d. different, depending on the information to which we are exposed.
