The study asked participants to work together in teams for 30 minutes to develop and record a university recruitment video.
The teams worked in rooms that either had chairs arranged around a table or with no chairs at all.
After making the videos, research assistants rated how the team worked together and the quality of the videos, while the participants rated how territorial their team members were in the group process.
The participants wore small sensors around their wrists to measure "physiological arousal" - the way people's bodies react when they get excited.

Members of the standing groups reported that their team members were less protective of their ideas; this reduced territoriality led to more information sharing and higher quality videos.
"Seeing that the physical space in which a group works can alter how people think about their work and how they relate with one another was very exciting," said Andrew Knight of the Olin Business School at Washington University.
The study was published in the journal Social Psychological and Personalty Science.
