Question 7

In a study of interpersonal closeness (Holland, Roeder, van Baaren, Brandt, & Hannover, 2004; experiment 2), researchers primed with either independence or interdependence by asking male and female subjects to think about the differences (independence) or similarities (interdependence) between themselves and their family and close friends.Then, they were asked to take a seat in a waiting area full of chairs where a jacket indicated the presence of another person.The dependent variable was the number of chairs between the subject's chair and the chair with the jacket.As predicted, subjects in the independent condition seated themselves farther away from the chair that appeared occupied than subjects in the interdependent condition did.In addition, men tended to sit further away from the jacket than women did.
