This thesis investigates how learners acquire vocabulary incidentally when engaging with captioned audiovisual materials, using an eye-tracking methodology to observe attention and processing patterns. It frames the study around specific research questions and defines linguistic targets to guide measurement. The design includes pretests and posttests, word-list and recall tasks, and quantitative analysis of comprehension, meaning recall, and form recall. Eye-tracking outcomes are summarized through measures such as mean dwell time and related inferential statistics, enabling an examination of how captioning influences attention and vocabulary learning outcomes.

FAQs

What is the main focus of the thesis?

The thesis examines incidental vocabulary learning through captioned audiovisual materials and uses eye tracking to measure attention and processing during learning.

How are vocabulary learning outcomes measured?

Vocabulary outcomes are assessed using pretests and posttests, along with recall tasks that evaluate comprehension, form recall, and meaning recall.

What eye-tracking metric is analyzed in the results?

The results include an analysis of mean dwell time, supported by descriptive and inferential statistical summaries.
