Figure 4. Effect of CDDI training.

Figure 4

A. Representative example of training performance from CB7. Blind field coarse discrimination performance prior to training was around chance, but gradually rose until it plateaued at ~80%, the upper limit of percent correct performance due to the 3:1 staircase utilized in training. B. Once performance reached this upper limit, subjects began to generate a normalized direction range threshold, which steadily improved during the course of training, as in this example with CB7. C. Following training, normalized direction range (NDR) thresholds became significantly lower (black bar) than pre training (checkered black bar) and statistically similar to performance in intact portions of the visual field (grey bar). D. Following CDDI training, subjects partially recovered FDD thresholds (black bar). However, performance remained impaired relative to the intact field, regardless of how the intact field was tested (grey bar = FBA cue test, white bar = neutral cue test). Values are means ± SD. Paired student’s t-test, alpha = 0.05, **p<0.001.
