Abstract
Eight Ss learned three lists of nonsense syllables (0%, 53% and 100% association value) on three successive days while several physiological variables were recorded. Ss showed significant increases in both palmar skin conductance and heart rate with the 100% list as compared with the 53% and 0% lists. These findings were interpreted in terms of greater degrees of physiological arousal during periods of superior performance.
