To your edit: The dots do make sense.

This is an overlay of every participant. So if 100 women clicked in the same 10 places, for instance, they would be red. While places 50 women clicked would be yellow.

Also, even if this was eye tracking of one person, it could still make sense. Red != 100%. Red is the place where the most time was spent looking. So of 1s was spent on all the dots, and everywhere else was less than 1s, then red. Comparing it to the male chart is what makes it seem off, but the comparison of color doesn't matter, it's the math.

I think their question was why would all the women click the same ten random places rather than spread the heat map out more broadly along the dark area?

Exactly, thanks.

Ahh, that's more clear then, sorry!

Heat map images were analyzed using canonical correlation (Rc) to determine the relationship between the two groups; dispersion testing to decipher spatial uniformity within the images; the Structural Similarity Index (SSIM) to characterize the nature of image patterns differences; and, the Breslow–Day Test to specify pattern locations within images.

Basically:

  • n women clicked somewhere on the bush
  • The bush is officially located at coordinates x/y
  • Place heat map point (circle) n times at x/y (the bush)
