As an expert in the field of cognitive psychology, I can provide insights into why people forget what they have learned. Forgetting is a natural part of the learning process and can be attributed to several factors, which I will discuss in detail.
Step 1: English Answer
Forgetting as a Cognitive Process
Forgetting is not a failure of the cognitive system but rather a natural part of how the brain processes and stores information. The human brain is designed to filter out unnecessary details to focus on what is important. This filtering process can sometimes lead to the loss of information that was once considered important but is no longer deemed relevant.
Short-Term vs. Long-Term Memory
One of the primary reasons for forgetting is the distinction between short-term and long-term memory. Short-term memory, also known as working memory, has a limited capacity and duration. It can hold a small amount of information for a brief period, typically around 20 to 30 seconds. If the information is not rehearsed or encoded into long-term memory, it is likely to be forgotten.
The Role of Repetition and Encoding
For information to move from short-term to long-term memory, it must be encoded and rehearsed. This process involves repetition, elaboration, and association with existing knowledge. The more an individual practices and relates new information to what they already know, the stronger the neural connections become, and the more likely the information is to be stored in long-term memory.
Interference Theory
Another reason for forgetting is the interference theory, which suggests that new information can interfere with the retrieval of old information. There are two types of interference: proactive interference, where old information makes it difficult to learn new information, and retroactive interference, where new information makes it difficult to recall old information.
The Spacing Effect
The spacing effect is a learning phenomenon where information is better remembered if studied over time, rather than in a single, intensive session. Cramming for an exam, for example, is less effective than spacing out study sessions over a period of time.
Ebbinghaus Forgetting Curve
The Ebbinghaus forgetting curve, developed by Hermann Ebbinghaus, illustrates how the retention of learned material decreases over time if there is no review or rehearsal. The curve shows a rapid initial drop in retention followed by a slower decline.
The Role of Emotions and Stress
Emotions and stress can also impact memory. High levels of stress can impair memory function, making it difficult to encode and retrieve information. Additionally, emotional events tend to be remembered more vividly than non-emotional ones, which can sometimes overshadow other memories.
The Importance of Sleep
Sleep plays a crucial role in memory consolidation. During sleep, the brain processes and consolidates information from the day, transferring it from short-term to long-term memory. Lack of sleep can disrupt this process, leading to difficulties in remembering learned material.

The most common reason why students forget is because the material is under learned. ... Learning is a process that takes time and repetition for humans to move information from short-term memory toward long-term memory. That is why when material is reviewed once or twice; it is difficult to remember for quizzes and exams.Mar 25, 2015
