In a famous scene from the classic movie Pretty Woman, wealthy businessman Edward Lewis gives Vivian Ward, a Hollywood hooker, a stunning ruby and diamond necklace worth $250,000 to wear out for the evening. At the sight of the necklace, Vivian’s eyes widen and a broad smile lights up her face. Even though it is clear the necklace is only out on loan, Vivian cannot contain her thrill and excitement. Edward, by contrast, displays only the slightest smirk of satisfaction in Vivian’s delight with the jewels.

Movies and television shows are replete with this gender dichotomy in emotional expressiveness, with strong men who say little and reveal even less with their facial expressions (think Dirty Harry, the Duke, Agent Gibbs, Walt Longmire), and equally strong but very expressive women who wear their hearts on their sleeves (think Scarlet O’Hara, Ellen Ripley, Erin Brockovich, Bridget Jones). But is this simply a Hollywood stereotype, or are women in fact more emotionally expressive than men?
