Final answer:
The term 'incapable of being satisfied' is synonymous with 'insatiability'. The concepts of satisfiability, contentment, and set point theory do not describe this state of never being satisfied.
Step-by-step explanation:
The concept of being 'incapable of being satisfied' is synonymous with 'insatiability'. The other options provided in the question do not pertain to this concept. 'Satisfiability' implies the possibility of being satisfied, 'contentment' denotes a state of happiness and satisfaction, and 'd.ation' appears to be a typographical error or irrelevant to the context. Insatiability refers to an unquenchable desire or need that cannot be fulfilled to the point of satiation, which is fullness or satisfaction.
The Schachter-Singer two-factor theory of emotion and the set point theory are not directly linked to the concept of insatiability. The Schachter-Singer theory suggests that emotions are derived from a combination of physiological and cognitive factors. The set point theory involves weight regulation, asserting that the body has a certain weight range that it strives to maintain. None of these theories involve the inability to be satisfied. Similarly, self-efficacy is about the belief in one's abilities to perform tasks and is unrelated to the idea of insatiability.
