key term - Memory storage

Definition

Memory storage refers to the process of retaining information over time within the brain, enabling retrieval when needed. This process is essential for various cognitive functions, such as learning and decision-making, and highlights how information is organized and preserved in the mind.

5 Must Know Facts For Your Next Test

1. Memory storage involves different systems, primarily short-term and long-term memory, each serving distinct functions.
2. The capacity for short-term memory is limited, often cited as holding about 7 plus or minus 2 items at once.
3. Information can be encoded into long-term memory through various methods, including rehearsal, meaningful associations, and the use of mnemonic devices.
4. Long-term memory is divided into explicit (declarative) and implicit (non-declarative) memory, each handling different types of knowledge and skills.
5. Memory storage can be influenced by factors such as emotion, context, and the quality of encoding techniques used during the learning process.

Review Questions

• How does short-term memory differ from long-term memory in terms of capacity and duration?
  • Short-term memory has a limited capacity, typically able to hold about 7 items for a brief period of 20 to 30 seconds. In contrast, long-term memory can store vast amounts of information for extended durations, ranging from days to a lifetime. This distinction highlights how different types of memory storage function in managing and retaining information over varying timescales.
• What role does encoding play in the effectiveness of memory storage?
  • Encoding is crucial because it determines how well information will be stored in memory. Effective encoding techniques, such as elaboration and the use of mnemonic devices, enhance retention by transforming sensory input into meaningful formats that are easier to recall later. Poor encoding can lead to weak memory storage and difficulty retrieving information.
• Evaluate the impact of emotional factors on memory storage and retrieval processes.
  • Emotional factors significantly influence memory storage and retrieval by enhancing or impairing how information is retained. Strong emotions can create vivid memories, making them easier to recall due to their impact on encoding processes. However, extreme emotions may also lead to distortions or gaps in memory storage. Understanding this relationship helps explain why certain experiences are more memorable than others.

Encoding: The initial process of converting sensory input into a form that can be stored in memory, playing a crucial role in how well information is retained.
