A new study finds that the attractiveness of a lecturer affects how students learn.
The students listened to an audio recording of a twenty minute lecture. During the study each student viewed a picture of the supposed lecturer. The lecture didn’t change in two groups, but the picture associated with it did. One of the group watched a lecture with the attractive, when second with the less attractive speaker.
Their test scores increased by 9.5% (18.27 items correct on average versus 16.68) when they believed their lecturer was more attractive.
