Answer:
The correct answer would be option A, Observation.
Explanation:
When someone observes something for a specific period of time, closely monitors the act which is happening, the process is called as the Observation. Observation is done in research methodologies to find out the occurrence of the specific event, and then it is recorded or noted down to get the results of that observation.
In simple words, Observation is to observe someone's specific action for a certain period of time.
So in this example, when Dawn's parents record her hair pulling behavior for a specific period of time, they are actually making observation about the behavior of their daughter.
Regarding the definition of abnormality, it is correct to state that (A) it is difficult to define "normal" and "abnormal". Decontextualisation of users' experiences may result in pathologisation of culturally "normative" phenomenon and poor health care experiences. There is a wider debate that concerns both the biomedical and social sciences regarding the unresolved question of "normality" or "abnormality" and related to culture and psychopathology.
