Final answer:
Alternating euphoria and apprehension is an effect of bipolar disorder, which is noted for its mood swings between highs and lows. Cognitive dissonance causes discomfort by disrupting an individual's sense of consistency.
Step-by-step explanation:
Alternating euphoria and apprehension is an effect of bipolar disorder. Bipolar disorder is characterized by dramatic shifts in energy and mood, which includes cycles of euphoria (highs) and depression (lows). These fluctuations significantly affect an individual's ability to carry out day-to-day tasks. While there are various mental disorders that can affect mood and behavior, bipolar disorder is specifically known for these episodic swings.
Cognitive dissonance causes discomfort because it disrupts our sense of consistency. When we hold conflicting beliefs or values, or when our actions do not align with our beliefs, it results in psychological stress due to the inconsistency. This is an important concept in understanding human behavior and motivation.
