Final answer:
The feeling of post-purchase psychological tension is known as cognitive dissonance, which occurs when a person's beliefs are challenged by new information, leading to discomfort due to a disruption in consistency.
Step-by-step explanation:
The feeling of post-purchase psychological tension or anxiety is referred to as d. Cognitive dissonance. This is a phenomenon where a person experiences discomfort because it disrupts their sense of consistency. Our beliefs are affected when we experience a threat to our self-esteem or positive self-image which can be caused by holding two or more inconsistent attitudes, behaviors, or cognitions.
For example, you make a decision to buy an expensive gadget feeling it is the best choice. After the purchase, you might come across information about a better product or deal, causing you to question your decision. This situation can cause cognitive dissonance, as your beliefs of making the best decision conflicts with new information suggesting otherwise.
To reduce this discomfort, you might seek confirmation of your decision by focusing on the positive aspects of the gadget you purchased or by discounting the new information.
