The present study extends the hypothesis that“persons tend to interact more in group discussion with persons sitting opposite them than they do with their neighbors.” This effect seems to be manifested most strongly in groups with no designated leader. "It will tend to disappear in groups where group direction is shared about equally by the members and the designated leader, and it will be reversed in situations where the designated leader gives very strong direction."
