Smile at Party and People Are More Likely to Remember Seeing Your Face There

When you smile at a party, your facial expression is emotionally consistent with the happy context and as a consequence other guests will in future be more likely to remember that they’ve seen your face before, and where you were when they saw you. That’s according to a team of Italian researchers led by Stefania Righi who have explored how memory for a face is affected by the emotion shown on that face and the congruence between that emotional expression and its surrounding context.
The researchers first presented 30 participants (11 men) with 64 unfamiliar face and scene pairings. The faces were either smiling or fearful and they were either presented alongside an image of a happy scene (e.g. a party) or a fear-inducing scene (e.g. a car crash). The participants’ task at this stage was simply to indicate whether each face-scene pairing was emotionally congruent or not.
Next came the memory test. Different faces (some previously seen, some new) were flashed up on-screen against a black background and the participants had to say whether they’d seen the face before or if it was entirely new. After each face, three scenes appeared of the same genre (e.g. three party scenes), and the participants had to say which specific scene the face had previously appeared alongside.
