Abstract
Dogs were trained in a shuttle box to avoid an electric shock preceded by a metronome signal; 2 levels of shock were used. A heart-rate-increase response, as well as the avoidance response, was acquired at a faster rate and to a higher asymptote by the high-shock group; this group also extinguished the responses more slowly. The data suggest "that amount of primary drive-reduction influences the growth of an autonomic response related to 'anxiety,' and that amount of secondary-drive reduction influences the growth of an avoidance response."
