Figure 2. Effects of chronic intermittent ethanol (• and ▾) or saline (□ and ▵) exposure during adolescence or adulthood (respectively), on type1 working memory (panel A) and type2 working memory (panel B) errors over the 1st 5 days of training in the DNMTP.

The histograms represent the cumulative effect of ethanol (black bars) and saline (white bars) on type1 (panel C) and type2 (panel D) working memory errors. Data are expressed as means ±SEM (n = 5 adolescent saline, n = 5 adolescent CIE, n = 5 young-adult saline, n = 7 young adult CIE, n = 6 adult saline, n = 6 adult CIE).
