Fig. 3. Effect of visual condition manipulations on average movement times (error bars show
±SE) and mean age ±SE is shown in parentheses: A) Children F 4,44 =10.09, p<0.01 B) Young
adult F 4,44 =7.24, p<0.01 C) Middle age adults F 4,44 = 4.23, p<0.01 D) Senior adult F 4,44 = 1.86,
p=0.19. In young adults, FV was significantly faster than VMO and NV, but not different from
the other simple feedback conditions (FVC and VPV). Also of note is the lack of any discernable
condition effect in the group of older adults. Adapted from (Grabowski & Mason, 2011).
Fig. 4. Peak velocity results for children, F 4,44 =5.32, p<0.01. All conditions show a slowing
compared to the natural viewing in the FV condition.
