Invisible Walls (1968)

Discusses the importance of social interaction and personal space within a culture. It explains how members of a society develop shared expectations and behaviors that facilitate communication, including non-verbal cues and gestures. As individuals grow, they learn cultural norms regarding personal space, which varies across cultures. The film describes an experiment where actors invade the personal space of unsuspecting subjects, revealing common reactions such as body stances, eye aversions, and fidgeting. It highlights differences in how men and women respond to personal space violations and notes that children have different boundaries compared to adults. The film concludes by suggesting that as populations grow, personal space may become increasingly limited.
