FIGURE 3.
The proportion of people (%) in each condition of the Speelman et al. (2010) experiment that exhibited a particular “effect size” (i.e., a reduction in RT of a particular amount), or greater. Effect size was calculated as the difference between Pre-test RT and Post-test RT as a percentage of Pre-test RT [100 × (PreRT – PostRT)/PreRT]. Original data values are presented in Table 2.
