Memory explained
Memory functions like a computer through information processing.
Read the full explanation
It begins with 'input', where sensory information from the environment enters the system (e.g., hearing a voice). Next is 'processing', where the brain interprets this information. Finally, 'output' occurs, which is the resulting behaviour, such as writing a note. To retain information, three stages occur. 'Encoding' transforms sensory input into a usable format, like acoustic or semantic codes. 'Storage' involves holding this encoded information over time. 'Retrieval' is the process of accessing and bringing stored information back into conscious awareness when needed, like recalling a fact during an exam.
Your focus
- Define the terms input, processing, and output in the context of information processing.
- Explain the processes of encoding, storage, and retrieval in memory.
- Apply the stages of memory and information processing to real-world examples.
Memory exam tips
Marking Points
- Identify input as the raw sensory information received from the environment.
- Describe processing as the brain's active manipulation and interpretation of data.
- Define output as the behavioural response or action resulting from processed information.
- Explain encoding as the transformation of sensory data into a storable format, such as visual or acoustic codes.
- Define storage as the retention and maintenance of encoded information over time.
- Describe retrieval as the process of locating and accessing stored information for conscious use.
Examiner Tips
- 💡Use the computer analogy (input, process, output) to structure your answers about information processing.
- 💡When defining retrieval, always mention that it involves bringing information back into conscious awareness.
- 💡Be prepared to apply the stages of memory to a novel scenario, such as learning a new skill or studying for a test.
Common Mistakes
- Confusing encoding with storage. Correction: Encoding is the transformation of data into a usable format, whereas storage is the maintenance of that data over time.
- Using input and encoding interchangeably. Correction: Input is the raw sensory data entering the system, while encoding is the active process of converting that data into a memory trace.
- Misunderstanding output as only verbal communication. Correction: Output includes any behavioural response or action resulting from processed information, not just spoken words.
