Dr. Baptista is attempting to train both birds and rodents to fear a clicking sound by pairing the click with presentation of shock. The birds respond with fear to the clicking sound very early in the experiment, but the rodents take a long time to learn. Dr. Baptista notes that the rodents' mating calls sound very much like the clicking noises used in the experiment. What would explain the rodents' slow learning in this study?
◦
the superiority of fear conditioning in birds◦
learning deficits during the mating season as a result of divided attention◦
a general deficit in learning ability in this species of rodents◦
a biological constraint on learning due to evolved traits in this species
