Abstract
Two groups of tiger salamanders ( Ambystoma tigrinum ) were conditioned to respond to odorant-air mixtures of n -butyl acetate (8.9 × 10 −5 M) or n-butyl alcohol (6.7 × l0 −5 M). They were then given tests with various concentrations of the training odorants presented using a temporal forced-choice method of ascending limits. Results showed that reliable responses to odorant-air presentations were obtained with concentrations of n -butyl acetate above 2.4 x l0 −7 M and with concentrations of n-butyl alcohol above 8.5 × 10 −8 M. These results are in substantial agreement with previous dectrophysiological findings.
