Question

a service dog is learning new commands from its owner. the dog owner is speaking prompts and using sign language to teach the service dog the proper commands. after hearing the commands and noticing the hand movements, the service dog is able to determine the correct response. what does this scenario show about the brain’s ability to process different communication methods?

• the brain becomes overexcited and commits errors in multiple areas.
• the brain relies only on nonverbal gestures to control an outcome.
• the brain combines verbal and nonverbal inputs to make decisions.
• the brain relies only on verbal clues to accurately interpret information.

Explanation:

The scenario involves a service dog processing both verbal (speaking prompts) and nonverbal (sign language/hand movements) communication to respond. The first option is incorrect as there's no mention of errors. The second and fourth options are incorrect because they claim the brain relies "only" on one type of input, while the scenario shows both are used. The third option correctly states the brain combines verbal and nonverbal inputs to make decisions.

Answer:

The brain combines verbal and nonverbal inputs to make decisions.
