Final answer:
Feelings are short-term emotional reactions with limited arousal, differing from more intense emotions that come with higher levels of physiological responses. The correct answer is option D).
Step-by-step explanation:
The concept that is defined as short-term emotional reactions generating only limited arousal is feelings. This term is often used to describe the emotional state when someone reacts to something, but the arousal and intensity are not as high as what may be considered a full emotion.
While feelings are commonly associated with a particular physiological arousal, such as an increase in heart rate or sweating, the level of arousal is generally lower than that of a more intense emotion, explaining why a feeling is considered short-term and generates limited arousal.
The distinction between feelings and emotions is significant in the study of psychology, where emotions are understood to be more intense and often come with a clear trigger, whereas feelings are considered to be less intense and may not be directly linked to a specific event or stimulus.
