Set up an .eaf with a video of an old HPP participant, with two tiers: left look and right look.

Trainee: open your assigned .eaf file.

Make sure your volume is down so you are not influenced by the auditory stimuli. Go to Options>Segmentation mode... and make sure the following segmentation options are selected

One keystroke per annotation, press to mark start, release to mark end

Delayed mode (checked): compensate for keystroke delay (ms): 300 ms

Segmentation key: enter

Now you are ready to begin segmenting. Navigate to the beginning of the video.

Drag the top window down to make your video as big as possible, but make sure you can still see your annotation tiers.

Use the up and down arrow keys to navigate between your codeable tiers-- the one that is selected and that you are currently making segmentations on will appear larger in red on top of the list of tiers.

Press play. Critically, when the child turns their head to one side or the other, make a segment on the corresponding tier by pressing and holding the enter key while they are looking, and releasing it when they look away. You will have to switch between tiers live (by using the up and down arrow keys): this is not identical but similarly paced to the process of coding an HPP study in the Habit software-- in the real deal, we use 4 when they look to the left, and 6 when they look to the right.

Practice with several files!
