Memory Psychology: Types and Processes
This page provides a comprehensive overview of memory types and processes in psychology, focusing on the multi-store model of memory and various memory retrieval methods. It delves into the intricacies of episodic, semantic, and procedural memory, as well as the encoding and retrieval processes essential for understanding how our minds store and access information.
The document begins by defining memory as the encoding, storage, and retrieval of stored information when needed. It then outlines the three main types of memory:
- Episodic Memory: This refers to memories of personal events or experiences in one's life.
Example: An episodic memory could be a holiday you took last year.
- Semantic Memory: This type of memory is for facts and general knowledge.
Example: Knowing that the capital city of England is London is an instance of semantic memory.
- Procedural Memory: This memory helps us recall information for complicated skills.
Example: Recalling how to ride a bike is a procedural memory. This type of memory is stored using a motor code rather than a verbal code.
The page then delves into the multi-store model of memory, explaining the characteristics of short-term memory (STM) and long-term memory (LTM):
Short-Term Memory (STM):
- Information passes from the sensory store to STM
- Limited duration of up to 30 seconds
- Capacity of 2-7 items
- Encoding is mainly acoustic (based on sound)
Long-Term Memory (LTM):
- Information passes from STM to LTM through deep processing
- No specific duration limit; could last a lifetime
- Unlimited capacity
- Encoding is mainly semantic (based on meaning)
The document also covers the three main encoding processes:
- Acoustic Encoding: Holding information in memory in the form of sound.
Example: Repeating a phone number to yourself until you can remember it.
- Visual Encoding: Storing information in memory in the form of a picture.
Example: Visualizing your garden when asked about its size.
- Semantic Encoding: Encoding information through its meaning.
Definition: The ability to understand and use words and concepts.
Lastly, the page discusses retrieval processes:
- Recall: Searching our memory for information.
Example: Being asked for the capital of Bermuda and recalling the answer from memory.
-
Recognition: Being presented with items and asked if we remember them from previous exposure.
-
Re-learning: Being exposed to previously learned but forgotten information and relearning it more quickly.
This comprehensive overview provides a solid foundation for understanding the key concepts in memory psychology, including the working memory model, episodic vs semantic vs procedural memory, and the processes of memory in psychology.
