The goal of the course was to discuss
"irrational beliefs" about self.
(Ellis 1977 rational-emotive therapy)
In the course 15 current beliefs were introduced one at a time in 5 minute mini-lectures, followed by a class discussion on how these work out in every day life. Sometimes Ss were asked to do home exercises.
