Question

  Dr. Williams’s independent variable would be watching TV, and the dependent variable would be behavioral change after watching TV. His experimental group will be a set number of people of similar characteristics, watching TV for the same number of hours, and in the same setting observing their behavior. The control group will be the same subjects that are not watching TV in the same setting or for the same number of hours, while observing their behavior. Dr. Williams should consider the age, sex and physical environment of the subjects in order to increase the validity of the study A key ethical principle for human research is that research participants should be protected from harm or discomfort. Do you think that the study you described above satisfies this principle? What is one thing you could do to either re-design the study or add protections for participants to minimize possible harm? With this modification, do the potential benefits of the knowledge gained from the study outweigh the potential harm to participants?

Explanation / Answer

The study described above satisfies the principle of protecting from harm or discomfort is subjects are not made to watch television at a very close distance and for very long hours at a stretch; if these conditions are not meet one can re-design the study or add protections for participants to minimize possible harm by keeping the subjects at a safe distance while watching the TV and not making the subjects watch TV for too long hours. With this modification, the potential benefits of the knowledge gained from the study outweigh the potential harm to participants as now the subjects will be safe from the harm of viewing TV at a close distance for long hours as it can cause problems in vision if repeated.
