As researchers Ashley D. Brown and Jared R. Curhan of the Sloan School of Management at MIT demonstrate in two experiments, physiological arousal isn’t always detrimental: “It turns out that the effect depends on whether you are someone who dreads or looks forward to negotiating,” Brown explains.

New Research From Psychological Science
Read about the latest research published in Psychological Science: One for All: Social Power Increases Self-Anchoring of Traits, Attitudes, and Emotions Jennifer R.
