This research examined generality of the phylogenetic rule that birds discriminate frequency ranges more accurately than mammals. Human absolute pitch chroma possessors accurately tracked transitions between frequency ranges. Independent tests showed that they used note naming (pitch chroma) to remap the tones into ranges; neither possessors nor…

Evidence that outcome associations, position associations, and response patterns each contribute to performance in animal serial learning came from two experiments in which three-trial series of rewarded and not-rewarded trials were examined. Response patterns were disrupted in Experiment 1 by placing animals directly in the goal on selected…
