Figure 4. Contrast sensitivity functions (CSFs) with AO correction in trained and untrained children and in untrained adults.

(a) CSFs with AO correction in the trained (‘') and untrained (‘') children. Error bars represent the standard error in contrast sensitivity across subjects. (b) CSFs with AO correction in the trained children (‘') and adults (‘'). Error bars represent the standard error in contrast sensitivity across subjects. The solid lines are curve-fits with difference of Gaussian (DOG) functions.
