Supplementary Table 1 displays mean group errors (expressed as a proportion of go and no-go trials) and mean go RT for the first and final training session (completed with the researcher present) to illustrate task performance over time.
All data are presented as the mean group value ± the standard error of the mean.
where VP is the phenotypic variance, VG is the genetic variance, VE is the environmental variance, R is the number of replications for each generation, MST are the mean squares between groups (between generations), and MSE are the mean squares within groups (error).
Group mean error rates on each of the 12 pre-sleep and 12 post-sleep trials are shown in Table 1 and displayed in Fig. 1A.
The two groups did not differ significantly in the proportions of trials with incorrect responses or outliers, on any of the tasks (across both groups, mean error rates on the central cue task and spatial cueing task were.03 and.04, respectively; mean outlier rates were.003 and.01, respectively).
However, while the Ibanez et al. study found a large effect size for difference in commission error rate (d = 0.89), the effect size was trivial in the Kaladjian et al. study, and the BD group mean commission error rate was lower than the control group.
To evaluate the accuracy of the designed system, the normalized root-mean-squared group-delay error, the maximum group-delay error, the normalized root-mean-squared phase error, and the maximum phase error are defined by (29).
All figures show group means with error bars ±1 s.e.m.m
For the overall group the mean prediction error was 1.40 D (SD, 1.60 D).
The times from inoculation to display of evident neurological signs suggestive of a prion disease (definite signs of a TSE, usually ataxia and dullness or nervousness) ranged from 18 to 54 months in both groups (mean and standard error of mean [SEM] 27.2 m and 3.6 m in the pre-1975 group and 30.1 m and 4.6 m in the post-1990 grespectivelytively).
