From: 10 Hz flicker improves recognition memory in older people

Figure 1

shows the proportion of real words that participants identified during the learning phase (ordinate) according to the frequency of flicker that immediately preceded them (abscissa). The points are the mean proportions of raw data, and the curves are the fitted quadratic trends over visible flicker frequencies. The solid circles and solid line are for participants aged 80 or less. The open triangles and dashed line are for participants older than 80 years. Note that flicker was not visible in the control (500 Hz) condition, so its effective frequency was 0 Hz. The error bars represent the overall standard errors of the means for each age group.
