Choosing a right poster
Up to 50% of people in the UK do not wash their hands with soap. Researchers at the Information School are looking into how combinations of images and text could encourage more people to do so.
Choosing a combination of text and images that encourages students to wash their hands after using the toilet. The most effective combination would be then used on the university website and in toilet facilities in universities.
We invited 30 participants to take part in a Facereader study. Facereader software captures facial emotions such as such as Happy, Sad, Anger, Disgust, Scared, Surprised, and Neutral, as well as the overall intensity of emotions.
Participants were presented with a set of PowerPoint slides containing various combinations of text and images designed provoke an emotion. They were shown the same messages on paper, and interviewed on which combination of text and images would make them wash their hands. We then combined analysis of Facereader emotions with the interview data to identify correlations with between intensity of emotions and spoken responses to posters.
Facial emotion, data was analysed by using Observer XT to calculate the dominant emotion expressed by participants for text and images. This presented problems as there wasn’t much correlation between participants in terms of facial reactions and the content they viewed. Rather individuals react different to different images based on their background, tolerance of unpleasant images, and how naturally expressive they are as a person. The has lead to the conclusion that more participants are required to find more noteworthy trends in the data.
The results of the study are being finalised, however so far, any poster involved metaphorical images (e.g. eyes watching the reader) images, combined with text warning them to use soap can invoke the strongest emotions.
