Eyebuy: Sweeping glances can 'cost you money'

Attention can be easily influenced

"In looking at shelves shoppers always see a subset of the assortment and which subset they see critically depends on their visual attention," says Streicher. "We were able to show that attentional patterns can be unconsciously broadened or even narrowed down by simple in-store communications. For example, the researchers first manipulated the breadth of attention of volunteering participants in a mini-market on the university campus in Innsbruck, Austria, with the help of digital displays, which are now also widely used as advertising media in stores. For a broad focus, different images were shown randomly and consecutively on the left or right periphery of the screen, while for a narrow focus the same images appeared always in the middle. The participants were then equipped with mobile eye tracking glasses and placed in front of a candy shelf from which they were to select products. Those persons who were previously presented with images at the periphery of the screen looked at significantly more areas of the candy shelf than the control group, who were presented the same images in the middle of the screen. In a second study in a supermarket, the researchers equipped the customers with pedometers to measure their in-store travel. Here too, they were shown product images on a display before shopping. While those customers whose attention was narrowly focused walked approximately 240 meters in the store, customers with broad attention walked over 300 meters. Significantly, the proportion of unplanned purchases in customers' shopping carts doubled. "We show that a very simple intervention before shopping can have consequences for a person's shopping behavior," is how Mathias Streicher sums up the results of the study, which has now been published in the Journal of Consumer Research.

Better manage shopping habits

The results of the study not only make a valuable contribution to consumer research, but also offer interesting findings for practical use. Thus, the research work gives indications, how contents of communication on digital advertising media should be arranged, in order to positively affect purchase behavior. On the other hand, the research also offers recommendations for people who want to better control their purchasing behavior. "Our research shows that unplanned purchasing already begins at the level of visual attention," summarizes the Innsbruck-based consumer researcher, who also has a simple tip for customers: "To reduce unplanned purchases, it is therefore better to avoid wandering glances in shopping situations -- preferably with the support of a shopping list."
