Figure 8. Experiment 1.1, fitted regression gradients from all control subjects and from DF in different testing sessions.
AB: Gradients of the regression lines are shown for the different subjects/sessions, for long (A) and short (160ms, B) stimulus durations. DF's data are shown in black/gray. Filled symbols show results from 3 sessions before she was tested on the annulus task (Experiment 1.2, Figure 7, tested in Sep 08); empty symbols show results from 2 sessions carried out after this. Control data are shown with colored symbols. The vertical dashed lines mark the separation between DF's gradients up till April 2008 and those of controls. The horizontal dashed line in B separates DF's results after testing with Experiment 1.2 from those obtained before.
