Brett Pelham: Your name influences your actions

One of the most bizarre demonstrations of the like-o-meter in action comes from the work of Brett Pelham, who has discovered that one’s like-o-meter is triggered by one’s own name. Whenever you see or hear a word that resembles your name, a little flash of pleasure biases you toward thinking the thing is good. So when a man named Dennis is considering a career, he ponders the possibilities: “Lawyer, doctor, banker, dentist… dentist… something about dentist just feels right.” And, in fact, people named Dennis or Denise are slightly more likely than people with other names to become dentists. Men named Lawrence and women named Laurie are more likely to become lawyers. Louis and Louise are more likely to move to Louisiana or St. Louis, and George and Georgina are more likely to move to Georgia. The own-name preference even shows up in marriage records: People are slightly more likely to marry people whose names sound like their own, even if the similarity is just sharing a first initial. When Pelham presented his findings to my academic department, I was shocked to realize that most of the married people in the room illustrated his claim: Jerry and Judy, Brian and Bethany, and the winners were me, Jon, and my wife, Jayne.

The unsettling implications of Pelham’s work is that the three biggest decisions most of us make– what to do with our lives, where to live, and whom to marry– can all be influenced (even if only slightly) by something as trivial as the sound of a name.

Gary Lupyan: Names help us remember

Studies in the late 1990s indicated that infants are better able to group objects into categories– animals versus vehicles, say– if they have already learned the category names…

Gary Lupyan of the University of Wisconsin at Madison… asked 44 adults to look at a series of images of imaginary aliens. Whether each alien was friendly or hostile was determined by certain subtle features, though participants were not told what these were. They had to guess whether each alien was friendly or hostile, and after each response they were told if they were correct or not, helping them learn the subtle cues that distinguished friend from foe– such as the presence of a ridge on the head. A quarter of the participants were told in advance that the friendly aliens were called “leebish” and the hostile ones “grecious,” while another quarter were told the opposite. For the rest, the aliens remained nameless.

Lupyan found that participants who were given names for the aliens learned to identify the predators far more quickly, reaching 80 per cent accuracy in less than half the time taken by those not told the names. By the end of the test, those told the names could correctly categorise 88 per cent of the aliens, compared to just 80 percent for the rest (Psychological Science, vol 18, p 1077). So naming objects helps us categorise and memorise them, Lupyan concluded.
