【 摘 要 】

The current study aims to explore the cognitive validity of the iBT TOEFL reading test by investigating test takers’ eye movements on individual items. It is assumed that successful test takers would adopt the intended reading processes, the same types and levels of cognitive processes that they would use for real-world reading tasks. Forty-seven Chinese ESL students participated in the study, in which they took the TOEFL reading practice testlet on a computer, completed comprehension subskill tasks, and had stimulated recall interviews. Results showed that test takers tend to rely heavily on careful reading skills, while expeditious reading skills were rarely activated. The scope of reading was often restricted to the local level; learners hardly read more than a paragraph to answer questions. In some factual question items, successful readers were more efficient in reading and locating key information, whereas such group differences were not found in other items. Lastly, the gaze plots suggest that learners’ eye movements manifest various interactions between comprehension subskills, primarily subject to bottom-up linguistic processing. The limitations and implications of learners’ eye-tracking data for test validation will be further discussed.
