Failure in retention and recall of learnt content is

Learning and remembering happen through three linked stages: encoding new information, retention (storing it over time), and recall or retrieval (bringing the stored information back to consciousness when it is needed).

The stem describes exactly a breakdown in the storage-and-retrieval stage: an inability to hold and reproduce previously learnt content. In educational psychology this specific breakdown is termed forgetting.

• Memory is the umbrella term for the entire capacity to encode, store, and retrieve information; it names the successful ability itself, not its breakdown.

• Retention is the process of successfully holding learnt material in the mind over time, which is the opposite of the failure the stem describes.

• Thinking is the cognitive process of reasoning, judging, and solving problems using information already available in the mind; it does not describe whether that information was successfully stored or recalled.

Hence, the failure to retain and recall previously learnt content is termed forgetting.
