EFFECTS OF SEATING DISTANCE AND ROOM ILLUMINATION ON THE AFFECTIVE OUTCOMES OF SMALL GROUP INTERACTION

Abstract
Three experiments explored the effects of variation in room illumination and in seating distance between members of a small group on moods, evaluations, attraction, and opinion expression. Groups of three subjects and a moderator discussed a socially relevant issue and then made several ratings. During the discussion, group members sat either very close to each other or far apart. In the first two studies room illumination ranged from normal lighting to darkness, and in the third study the room was either red or blue in hue. Check questions indicated successful manipulation of the variables. However, across the three experiments there were only slight effects for the several measures of affective response. The results indicate that, contrary to expectation, interaction distance is not per se a very powerful variable. Very likely, pleasant or unpleasant effect will depend on distance only under relatively circumscribed boundary conditions, which are, as yet, undetermined.
