Figure S1. d' N-back performance in men of sample 1. Comparison of variance indicated a trend toward less variance for 0-back-d' compared with 2-back-d' (F(1,140) =3.2, P = 0.07), as well as for 3-back-d' compared with 2-back-d' (F(1,140) = 2.9, P = 0.09).
Figure S2. Correlation between working memory and motor threshold (Sample 2). 2-back-d': difference between the Z-transformation of hit- minus false alarm-rates in the 2-back condition; rMT, resting motor threshold.
Figure S3. d' N-back performance in sample 2. Comparison of variance indicated significantly less variance for 3-back-d' compared with 2-back-d' (F(1,94) = 7.36, P = 0.008), but not for 0-back-d' compared with 2-back-d' (F(1,94) = 0.05, P = 0.48).
Table S1. Shared variances between 0-, 2-, and 3-back performances in men of sample 1.
Table S2. Accuracy and d' correlations with rMT in sample 2.
