What did the development of brain imaging technology allow researchers to do?

Explanation:

The development of brain imaging technology allows researchers to study the brain and to look at the inner injuries in the brain and also drugs and chemicals effects in the brain.

Brain imaging uses several techniques to study the structure and function.

There are different Brain imaging techniques such as electroencephalogram, Magnetic resonance imaging, Functional magnetic resonance imaging,Positron Emission Tomography,Near infrared spectroscopy, etc.

Thus Brain imaging techniques allow researchers to observe the problems inside the brain without doing neurosurgery.

the answer to the question is punishment. or more specifically, positive punishment.

positive punishment occurs when a behavior is given a negative consequence for the individual doing the behavior.

sara no longer wants to ask questions (the behavior) because she is ridiculed by mr. smith (the punishment).

reinforcement is inaccurate because reinforcement always gives positive consequences for the individual doing the behavior, be it by introducing a pleasant consequence or removing an unpleasant one.
