This paper explores functional hemispheric asymmetries in the perception of auditory signals in a marine mammal species, the sea lion. Using a head-orienting task toward sounds we found a right ear--left hemisphere--advantage for conspecific calls in adult and subadult California sea lions (Zalophus californianus) that was absent in infants. Non-conspecific sounds did not elicit lateralized reactions in any age group. These findings show that maturational steps regarding communication in the… CONTINUE READING
