A recent article on the Psychonomic Society’s website features exciting new findings by UBC Psychology’s’ Dr. James Enns and Allison Brennan: social interaction may help team performance.
Their research also explores the factors that mediate this effect, contrasting two commonly used ideas about how people function in groups or teams: “Put two heads together and they are better than one. Put two heads together and they engage in group think or they do worse than the better head on its own. Which is it? Are two heads better than one, and if so, are there boundary conditions to this beneficial effects?”
“Unlike previous demonstrations of superior team performance, the study by Brennan and Enns was the first to pin down by rigorous mathematical means that there was more to the team advantage than statistical facilitation.”
