Two techniques that can be used when reading are scanning the text for particular information and reading for full comprehension. These two reading techniques may be achieved using different eye movements. This thesis explores the use of various eye movement measures for the purpose of comparing reading comprehension and scanning techniques. Eye tracking technology is used to detect the eye movements of readers while they read a section of text requiring them to scan the text for information or read for comprehension. Eye movement measures proved to be successful in differentiating between reading techniques. The eye movements involved in reading for comprehension were found to be different from the eye movements involved in scanning the text for information, as demonstrated by the differences in multiple eye movement measures between the two reading conditions. Notably large differences between the eye movements made by readers under the same reading conditions highlighted the highly variable and individual-specific nature of reading behaviour. The findings relating to the eye movements that are used for different reading techniques may be beneficial for people who seek to improve their reading skills. Eye movements could possibly become a useful part of reading instruction. These results may also be used as norms against which the eye movements of those with abnormal reading patterns could be compared for the purpose of diagnosis of reading difficulties.
