Suppose a rat was exposed to a flashing light followed by electric shock for 3 days. On the fourth day, the rat is placed in an operant chamber where it can press a lever for food pellets. If the rat makes 40 responses per minute when no flashing light is present but only 20 responses per minute in the presence of a flashing light, the suppression ratio would be

A rat is given 20 exposures to a flashing light stimulus. Then, the flashing light is presented paired with food delivery. Compared to a rat that did not receive the initial 20 exposures, this rat took a long time to develop a CR to the light. The slower learning is due to the
