When monkeys with Klüver-Bucy syndrome pick up lighted matches and snakes, we do not know whether they are displaying an emotional deficit or an inability to identify the object. What kind of research method might help answer this question?

controlled experimental research

Explanation:

Given that absence of the temporal lobe is known to cause both emotional deficit or an inability to identify an object in animals.

Hence, in this case, the kind of research method that might help answer this question is CONTROLLED EXPERIMENTAL RESEARCH. Whereby, the experiment will have the control group, the experimental group, independent variable, and dependent variables.

The control group would be comprised of animals that lack or has temporal lobe damage

The experimental group would also be animals that originally lack or has temporal lobe damage, but would be infused with temporal lobe lesions

Them the researcher will then compare the two groups of animals based on the effect of the infused temporal lesion on one group and none in another.
