Retrograde enhancement by alcohol of delayed free recall performance.
Two experiments are reported in which retrograde enhancement of human memory by alcohol was observed. In both studies male undergraduate volunteers performed an immediate free recall task before and after consuming either alcohol (0.66 abs alc/kg) or placebo. About two hours later, many words as they could delayed free recall was tested when subjects were asked to write down as many words as they could remember from the free recall trials in the session. Subjects given alcohol recalled significantly more words from lists heard before drinking than subjects given placebo; this effect appeared more pronounced for words from the primacy portion of the lists. The possibility that this retrograde enhancement effect is due to alcohol's effects on brain reward systems is raised.
