"<u>Single-source tracking</u>" is the "posttest method" used in "broadcasting commercials".
<u>Explanation</u>:
Single- source tracking is a post test which means this test is taken after a specific advertisement is out in the market. This method is basically used to know the reactions, and views about the products or services intended through those commercials. Consumers present in the television set or any supermarket checkout counter or any place where they go through this test, where the assigned people look after the consumers to know their reaction by tracing it from their face.
Answer:
The researcher's and the IRB chair that the study is exempt from IRB review is wrong.
Explanation:
IRB is an acronym that stand for Institutional review board. The Institutional review board is responsible for reviewing how researches are been conducted by researchers. Depending on how ethical your research is, after the review you might get your research to be full, expedited, and/or exempted.
In order to be able to deal with this kind of question, we must be able to know what 45 CFR 46 is, that is the code for the categories of exempt Human Subjects researches.
According to 45 CFR 46.101 , when a research is been conducted in correction centres such as the prisons, one can not exempt it.
(Please not that the Institutional review board, IRB is also known as the independent ethics committee).

When Abayomi has a physiological reaction produced in the body by the perception of aversive or threatening events, she is experiencing Stress.
A threat to survival or well-being, real or imagined, causes animals and humans to experience anxiety, a psychological, physiological, and behavioral condition. Increased alertness, expectation, autonomic and neuroendocrine activation, as well as particular behavioral patterns, are its defining characteristics.
Having pathological anxiety makes it difficult to successfully handle obstacles in life. the biology of fear and anxiety will be examined from a systemic (brain-behavior relationships, neuronal circuitry, and functional neuroanatomy) and cellular/molecular (neurotransmitters, hormones, and other biochemical factors) perspective.
Psychopathology appears to be a consequence of predisposing factors (or traits), which result from numerous gene-environment interactions during development (particularly during the perinatal period) and experience (life events). Although the recent advent of noninvasive investigation techniques in humans, such as the various neuroimaging techniques, undoubtedly opens new areas of research in this area, these models have been crucial in identifying the biological correlates of fear and anxiety.
