"That's a little bug in the script, so I can fix this. It is calculating the
relative looking time (in percent) which it needs for the habituation criterion, but it is
dividing by 0 because due to the look away the actual looking time was 0."

"At first I thought I'd implement the change by using the drift-check target built into the

MIN_ATTENTION_FOCUS and gaze samples outside attention getter's AOI don't make it start over. So it won't that hard to get passed the attention getter. At the same time you can use a larger MIN_ATTENTION_FOCUS duration (I've set it to 500ms, for trying).

counter doesn't start running until the first sound stimulus starts there will be no harm
I think. It is just that the smaller the AOI is the more centered the participant is

In defs.zm you can turn enable or disable the max lookaway duration. Currently you have it enabled in habituation and disabled for the other phases. You can disable (set to 0ms) forhabituation as well.

If you do want the 2s time out, just set MAX_LOOKAWAY_DURATION in defs.zm. In the latest version I provided yesterday I had set it to 0ms, since I understood you wanted that. Just set it back to 2000ms. The way it is now (with no end-trial-on-tool-long-lookaway) it will be pretty hard to reach the habitiation criterion anyway, so it's incorrect now.

I assume you want to keep the animation (it scares me).
Open left_page.zm and right_page.zm.
1. The canvas is now 400x400 pixels. So whatever shape you place on the canvas it will
always be chopped off at 400x400 pixels. Make the canvas say 1000x1000 pixels?
2. The ImageShape called attention has a load() function. This function has a width (w)
parameter that controls how to scale image. It was set at 400 which means the image will
be scaled to a size of 400 pixels wide. Make it 800. Since the animation will scale up and
down the image by a another factor of 1.25 the maximum image width will match the canvas
width.
3. If the animation is not really smooth, you might want to size down the checkerboard PNG
to 400x400 or so? This will be more efficient and it will look about the same.

4. Run the experiment. Each time you hit Enter or space the next type of animation will be
shown. They might go a little fast for an infant. That can be tweaked. You can also
combine them with playing the tune. Animation number 4 is supposed to show a lauching baby
instead of the horse, anyway you get the idea. For number 5 you could add more/other
images. If you like one of the animations you could use that one instead of the welcoming
slide show you already have.

4. Run the experiment. Each time you hit Enter or space the next type of animation will be
shown. They might go a little fast for an infant. That can be tweaked. You can also
combine them with playing the tune. Animation number 4 is supposed to show a lauching baby
instead of the horse, anyway you get the idea. For number 5 you could add more/other
images. If you like one of the animations you could use that one instead of the welcoming
slide show you already have.
