Final answer:
Forgetting in long-term memory is most likely due to encoding failure, which occurs when we fail to properly store information in our memory.
Step-by-step explanation:
Forgetting in long-term memory involves the inability to retrieve information previously encoded and stored over an extended period. Factors like interference, decay, or retrieval failure contribute to forgetting. Memory consolidation and organization play roles, and retrieval cues or context can influence the ability to recall stored information accurately.
Forgetting in long-term memory is most likely due to encoding failure. Encoding failure occurs when we fail to properly store information in our memory in the first place. One example of encoding failure is when we don't pay attention to the details and actively process information. For instance, most people can't accurately recall the details on a penny because they never encoded those details in their long-term memory.
