By measuring the Galvanic skin response, Dr. Laub is trying to avoid the problem of:
<h3>What are demand characteristics?</h3>
Demand characteristics are a form of behavior that participants in a research work exhibit. If they are able to fathom the cues in the research, they often tend to change the way that they behave.
If they change the way they behave, accurate results will not be obtained. So, this issue must be avoided at all costs and that is why Dr. Laub measures the Galvanic skin response.

Answer: a. testing effect
Explanation:
Testing effect is a type of threat to internal validity of an experiment. Internal validity is assessing whether a factor makes a difference in an experiment or not and if it does, whether there is adequate evidence to support this correlation.
Testing as a threat to internal validity is when a second test is taken on the outcome of a first test. Other internal validity threats are history, maturation, instrument modifications.
