Experiment 1, group and individual performance in blur and noise conditions. a Mean performance, split by age group, fit to cumulative Gaussian functions. Dotted horizontal lines represent chance (50%) performance on the task. b Bar plots show mean 75% performance thresholds by age group. In both the blur and noise conditions, these thresholds are significantly different at the group level, p < 0.001. Error bars are 95% bootstrapped confidence intervals. c Stimuli with blur and noise at the 75% mean threshold level shown in (b), separated by age group. d Exemplar individual participant data from eight participants (four per age group), for blur and noise conditions, fit to cumulative Gaussian functions. Values inset in lower left of each subplot are the 75% performance thresholds for each participant and each condition
