FIGURE 1.

Average data of the 8 control participants in Tillmann et al. (2008) on the left, and their individual data on the right [this group of control participants had a mean age of 65 (±10) years]. For comparable data patterns of group of students, see Bigand et al. (2001) and Tillmann et al. (2008), of groups of children, see Schellenberg et al. (2005), and of another group of control participants as well as their individual data patterns, see Tillmann et al. (2007). Positive and negative values indicate facilitated processing for related and less-related targets, respectively.
