BRINEZ-HORTA, JOSÉ ARTURO  e  OYUELA-VARGAS, RAÚL. Effects of low doses of alcohol on declarative memory in humans. Univ. Psychol. [online]. 2011, vol.10, n.3, pp.923-935. ISSN 1657-9267.

This study assessed the effect of low doses of alcohol (0, 0.035, 0.150, 0.300 g) on two elements of explicit or declarative memory, in 16 participants, 8 women and 8 men, with The Weschler Memory Scale III Text Test. A factorial 2 * 4 counterbalanced with repeated measures design was used. There were no statistically significant differences by gender, but there were differences among doses, specially 0.150 g / kg., which reduced episodic and semantic retrieval, between 43.9 and 62.9 % of effect strength, in intermediate term memory. These results provided evidence that alcohol in low doses has a more pronounced effect in semantic, rather than episodic memory, in the middle term.
