ABSTRACT

To sum up the main findings, Figure 1 and the statistical analyses showed a R E A for al l age groups, except for the 9-year-olds, during the N F attention condition. There was, however, a clear trend toward a R E A also in this group (see Figure 1). The right-ear scores increased for the age groups 16+ years, resulting in a slight increase in the R E A for these age groups. The scatter plots in Figure 4 show that the R E A was based on approximately 70-75% of the enlarged sample, with a narrower spread for the youngest groups. Figure 2 shows that although the R E A stayed statistically unchanged for the youngest age groups, it increased for the other age groups as a consequence o f focusing attention on the right ear (with a decrease for the oldest age group). This was also reflected in the corresponding scatter plots. Figure 3, finally, shows that all age groups except for the two youngest and the oldest groups showed an L E A when instructed to focus attention on the left ear. Aga in , the size o f the L E A increased from the age o f 10, with a slight decrease in the oldest age group.
