Slope of black line indicates rate of correct responding; slope of dotted line indicates rate of incorrect responding. Cumulative response totals are plotted along ordinate, minutes along abscissa. When dotted curve flattens, errors have been eliminated and only correct responding continues.

. Brain mechanisms and learning, a symposium. Psychophysiology; Learning, Psychology of. CINGULATE CORTEX Fk;. 7 Daily response curves. Slope of black line indicates rate of correct responding; slope of dotted line indicates rate of incorrect responding. Cumulative response totals are plotted along ordinate, minutes along abscissa. When dotted curve flattens, errors have been eliminated and only correct responding continues. Left curve in each pair indicates a day when left lever is correct; right curve indicates a day when right lever is correct. Large numbers above each pair indicate electric current setting in microamperes of the interference stimulus. In this scries with cortical stimulation, the stimulus does not interfere materially with animal's ability to learn. train caused few seizures and caused greater stimulus effects in other respects. Some animals were also given a series of special tests which will be described in more detail later. These were (i) a selt-stimulation test tor positive reinforcing effects; (2) a memory-performance test for confusion after criterion is reached each day; (3) a reinforcement-confusion test to find whether confusion persists when electric stimulation is programmed.
