Behavioral results for the four stimulus conditions from the simple viewing task. Accuracy (d’) and reaction time results were analyzed as a continuous variable of age (ln = natural logarithm transformation). Linear regression lines and Pearson correlation coefficient (r) are provided. Separate ANCOVA analyses for accuracy and reaction time with age as a continuous between subjects variable showed reliable age effects for both measures, but no age × stimulus interactions; thus, younger participants were less accurate and slower to respond than older participants but there was no overall difference in responding to the four stimulus conditions. * = P≤ .05.
