Figure 3
Performance on the AX-CPT-s in the SD group by genotype. Panels show d’ for each of the performance indices described in Table 1, in session 1 (BL, baseline) and session 2 (SD, sleep-deprived) for subjects homozygous for the C allele (C/C), heterozygous (C/T), or homozygous for the T allele (T/T) of the DRD2 C957T polymorphism. See Table 1 for interpretation of d’ changes. Error bars are ± 1 SEM. Brackets indicate statistically significant contrast comparing session 1 to 2 (p < 0.05); bracket without asterisk approaches significance (p = 0.10).
