Sixteen subjects participated in the study. The experiment consisted of four sessions. In the first session, visual attention was assessed by means of a laboratory task as well as by means of a more realistic task. Subjects in the control group merely repeated the task. In the fourth session, a parallel version of the realistic task was administered.
Results show that visual attention can be trained successfully.
In the laboratory task, repeating the task proved to be as effective as being trained by well-specified instructions. Furthermore, the performance of older subjects saturated after three sessions, whereas younger subjects continued to improve.
