Part IV-That's Not All
The researchers were concerned that the type of car waiting or some behavior of the driver of that car might make a
difference in the actions of the people in their first study. To deal with this, they designed an experiment. They used
a low status car (1985 Nissan Maxima) and a high status car (1994 Infinity Q45 or 1993 Lexus SC400). They had
three levels of intrusion: (1) no intrusion (no car waited for the spot), (2) low intrusion (the other car waited four
spaces from and facing the direction of the departing car), and (3) high intrusion (the car waited four spaces from
the departing car, turned on its turn signal, and honked the horn once after the driver sat behind the wheel). The
high status cars were involved in half of each of the intrusion conditions; the low status cars in the other half of the
intrusion conditions. An observer recorded the number of seconds it took the driver to leave the space after he/she
opened the door.
