Some animals, such as dolphins, dogs, and African grey parrots, seem to
exhibit cognitive functions typically associated with higher-order primates
such as chimpanzees, gorillas, and humans. Some parrots, for example, have
vocabularies of hundreds of words that they can string together in a
comprehensible syntax. This clearly shows that humans and primates are not
the only animals capable of using language to communicate. One parrot,
named Alex, has been known to ask to be petted or kissed and will exhibit
aggression if the gesture offered is not the specific one requested. Which of
the following, if true, would most strengthen the conclusion above?
- Dolphins can be trained to assist divers in ocean rescues.
- Gorillas in captivity often learn hand signals for food and water.
- Dogs are capable of sensing their owners’ moods and often exhibit concern if
they sense sadness.
- Chimpanzees can memorize long sequences of key punches on machines that
dispense food.
- Alex does not exhibit aggression when offered a gesture that he specifically
requested.
i am completely lost on this one....i mean i dont understand where is this communication happening....Choice E says that alex express no aggression but again how does it show that alex is communicating and with whom???/.....I am completely bowled....Please explain....
