그림과 텍스트로 구성된 읽기자료에서 과제유형, 텍스트의 줄 길이, 근접성 원리가 그림에 대한 시선응시에 미치는 영향 = Eye-tracking Study of Types of Tasks, Line Length, and Contiguity in Comprehension of Text and Illustration

다국어 초록 (Multilingual Abstract)

The purpose of this study was to invest the impact of contiguity principle and line length with different types of task on eye tracking data. For the study forty-seven college students participated to the experiment. The independent variables were line length and contiguity principle with the different tasks. In this study conceptual and procedural tasks were applied. The dependent variables were dwell time, eye fixation duration, and frequencies of fixations. For the analysis a set of AOIs was set on an experimental material. This study was conducted to measure the eye gaze, and SMI eye-tracking machine was used. The reading material was a scientific description of human hearing system. The content was mainly consisted of two parts: 1) text areas and 2) one image. The text areas were four functional descriptions of human organ parts in the ear system. The image was to show the inside of ear system. The result revealed that the effect by contiguity principle was stronger than non-contiguity principle when the line length is the same. It can be concluded that a contiguous image to text may increase the eye-fixation time. Additionally, contiguity principle may facilitate mental efforts to figure out the learning contents. There was a significant difference in a conceptual task. However, there was no significant difference in a procedural task. It was concluded that the text and picture was not enough to facilitate learning in the procedural task, because the increased complexities may hamper to pay more attention on a picture. Moreover, there should be additional design strategies for the complex task like a procedural task.
