Taste and volume preferences for alcohol in Macaca nemestrina.

Abstract

9 Macaca nemestrina monkeys trained to identify water and 5, 10, and 20% alcohols by the colors of the containers were tested under 0-, 24-, or 48-hr. fluid deprivation and tended to select water or 5% alcohol when very small quantities of all 4 fluids were presented simultaneously. Level of deprivation affected the consistency of this preference. In a 2nd series of experiments, preference was judged from volume intake in a 2-choice situation. Alcohol concentrations and deprivation levels were the same. Except for an increased consumption of 20% alcohol, the average results for the entire series were similar to those obtained by brief sampling. Position preferences affected the results more with the 2nd technique. (PsycINFO Database Record (c) 2006 APA, all rights reserved)
