FIGURE 8.

Prenatal ethanol exposure (PE) did not lead to more incorrect responses or omissions in the 2-choice reaction time task. These two types of errors both indicate lapses of attention. An incorrect response refers to an entry into a wrong water dispenser (which is not associated with the illuminating stimulus light) at the right time. An omission refers to an extremely slow response with reaction time > the maximal trial duration. These two types of errors occurred infrequently in well-trained rats, but a sex difference was observed. Specifically, PE caused no change in incorrect response (in % of trials, A) or omission (in % of trials, B) in males whereas PE led to reduced incorrect responses in females. Moreover, PE females made fewer incorrect responses and omissions than PE males. Data are presented as Mean ± SEM. **p < 0.01, control vs. PE in females. ^#p < 0.05; ^##p < 0.01, male vs. female in PE rats.
