This week I finished up the list of tasks. We decided on using posts that refer to C++ code only (initially we had discussed both Java and C++) for simplicity. Categorized by difficulty, I found 10 simple tasks and 10 average-complex tasks that would be possibilities for our study. I decided to merge the 2 categories of average and complex since difficulty of tasks will vary between our subjects depending on personal experience. For our experiment design, subjects will need to determine the appropriate tags for a posting. So our next step is to come up with tags for each task in order to build lists of suggestions they may choose from.
Additionally this week we reviewed the paper "Reading Without Words: Eye Movements in the Comprehension of Comic Strips". This was an eye-gaze study using comic strips (animations only, no text) as visual stimuli. The researchers mixed the order of these comic strips and studied how this affects attention, which ultimately resulted in making the comic strips harder to understand which required more attention Correlation maps were then used to compare fixation locations in comic strips. Here, the researchers analyzed their data using t-tests studying variance between experiments (comparing the gaze-data in normal sequence of comics versus randomized sequence of comics).
