A simulated data set based on the means reported by Johnson and Rusbult (1989).
A data frame with 200 observations on the following 4 variables.
Subject identification number
Subject's level of commitment to their current romantic relationship
Attractiveness of target person
Average of 3 ratings: (1) to what degree are you attracted to X (1 = not at all, 9 = extremely), (1) how do you think a relationship with X would compare to your current relationship (1 = much worse, 9 = much better), and (1) to what extent do you think you would have a satisfying relationship with X (1 = not at all satisfying, 9 = extremely satisfying)
These results are sometimes used as a demonstration of the tendency to derogate unselected alternatives when commitment is high. Subjects reported their own level of commitment in a romantic relationship and then gave 3 ratings for a photograph that had been pre-tested to be either moderately attractive or very attractive.
