Final answer:
Congenital deviations can lead to abnormal head positions, and patients may not be aware of their condition. Aptitude refers to an individual's innate ability in a particular area, but it does not guarantee success. Effort and practice are necessary to develop skills and knowledge.
Step-by-step explanation:
Aptitude is the innate ability an individual has to perform a particular task. For instance, someone could have the aptitude to excel in math or music. However, aptitude alone is not sufficient to guarantee success. It also requires effort and practice to develop the necessary skills and knowledge.
In the case of congenital deviations, such as abnormal head positions, it is possible for individuals to be unaware of their condition. This can be due to various factors, such as the deviation being present from birth and the individual becoming accustomed to it, or the deviation not causing any discomfort or functional limitations. Therefore, the statement that patients with congenital deviations often are not aware of their abnormal head position is true.
