An eye tracking experiment on strategies to minimize the redundancy and split attention effects in scientific graphs and diagrams

Abstract

The focus of this study is investigating efficiency of coding and grouping methods in reducing split attention effect in scientific graphs and diagrams by applying local changes in the structure of scientific materials. The diagrams and graphs are regularly used in the structure of materials along with textual explanation to provide supplementary information and insight to the readers and is referred as redundancy principle. In some cases, the redundant presentation of visual and textual content could lead to split attention effect and cognitive overload. Although, multimedia learning theory claims that in order to enhance learning, information should be presented in multi-mode format the design and implementation of the multi-modal presentation is of great importance. Having incredible flexibility, if multimedia elements are not applied properly, they cause confusion and adversely affect comprehension of the readers.
