Question

Answer the questions to get correct answers after you had read the passage on Compassionate Dog.

How Compassionate Is Your Dog? Can dogs recognize when their owner is in distress? In one study, 34 dog-owner pairs were recruited to participate in an experiment? in which the owner sat behind a magnetic door that the dog could push open. The pairs were randomly assigned to one of two conditions: in the distress condition, the owner said help in a distressed tone every 15 seconds and made crying sounds between speaking. In the control condition, the owner said help in a neutral tone and hummed between speaking. The vocalizations between the two groups were at the same volume. Let Group 1 be the distress condition and Group 2 be the control condition. 7Sanford E, Burt E, Meyers-Manor J, "Timmy's in the well: Empathy and prosocial helping in dogs," Learning and Behavior, 46(4), pp 374-386, December 2018.
