Question

if a participant goes to a research lab to have a wada test done, what is the researcher most likely examining in the participant?
multiple choice

• whether the participant has brocas aphasia
• whether the participant has a specific language processing center in his or her brain
• whether language has fully developed in the participants brain
• whether language is localized to one side of the participants brain

Explanation:

The Wada test (intracarotid amobarbital procedure) is used to temporarily anesthetize one hemisphere of the brain to determine which side is dominant for language function, i.e., if language is localized to one brain hemisphere. The other options are incorrect: Broca's aphasia is diagnosed via language assessment, not Wada; it is known humans have language processing centers, so this is not the test's goal; and the test does not evaluate full language development.

Answer:

whether language is localized to one side of the participant's brain
