Restricted visual scanning of emotional faces has been previously suggested as a possible mechanism of impaired emotional recognition in schizophrenia patients. In general, visual scanning measured through eye movements (i.e., visual scan paths) provides useful information about where on the face, and for how long, people look when judging emotions. However, these studies do not inform us how schizophrenia patients use visual information. Knowing where someone is looking does not tell us how he/she uses visual information. In contrast, with the Bubbles technique, this study showed which parts of facial features or what levels of spatial frequency were critical to make decisions about emotional expression of faces. Hence, this study provides information that is not available from studies using visual scan paths.
