Final answer:
Selective forgetting occurs when consumers do not remember all the information they see, hear, or read even after attending to and comprehending it. This type of forgetting can happen due to encoding failure or absentmindedness.
Step-by-step explanation:
Selective forgetting occurs when consumers do not remember all the information they see, hear, or read even after attending to and comprehending it. Forgetting can happen due to encoding failure, which means that information was not effectively stored in long-term memory. For example, if someone sees a penny but does not pay attention to the details, they are likely to have trouble recalling what the front of a U.S. penny looks like. Another type of forgetting is absentmindedness, which occurs when memory lapses happen due to breaks in attention or focus being elsewhere. So, in summary, selective forgetting can occur due to encoding failure or absentmindedness.
