Long-term memory: Episodic Flashcards
What are the types of declarative (explicit) memory?
Episodic
Semantic
What are the types of non declarative (implicit) memory?
Procedural memory
Define the term episodic memory.
Memory of events, specific attributes or episode (e.g., the weather was nice at Kingston yesterday).
Define the term semantic memory.
General knowledge, memory for FACTS (e.g., London is the capital of the UK).
Define the term procedural memory.
Memory of how to do something (e.g., how to shoot a basketball).
Explain the history of episodic memory.
Endel Tulving first defined the notion of episodic memory, and his conceptualization of episodic memory is still widely accepted even now.
What is an episode?
consists of the integration or binding of multiple types of information.
* For example: do you remember your first lecture at KU?
What does an episodic memory trace include?
Spatial information (classroom), temporal information (when was it), visual information (visual of the lecturer and your classmates), auditory information (sounds you have heard, voice of the lecturer), emotional information (excitement/disappointment for your first lecture). All the information is integrated into a single memory representation to form an episode and stored in long- term memory. The stored episode will then become an episodic memory representation.
How do we measure episodic memory in the lab?
- In an episodic memory experiment, you will learn a sequence of items in a learning (encoding) phase. Each item is a memory trace (=EPISODE), which consists of the item, spatial information (spatial relations between items), temporal information (sequence of items), and/or visual information (image of paired items).
- Then, you will be asked to retrieve those items in a subsequent retrieval phase. You may be asked to recall those items from memory, or you may be presented with those items again along with new ones and be asked to differentiate between old and new items. This is called a recognition memory test
What are the two processes of episodic memory?
Encoding
Retrieval
What is encoding?
When you first learn and develop a memory trace for events and information.
What is retrieval?
When you access that information and bring it back “online”.
- Access the information stored during encoding.
What is an approach to understanding episodic memory
encoding?
Levels of processing (LOP) Framework (Craik & Lockhart, 1972)
- The “deeper” we process the information during encoding, the higher the chances of later successful retrieval. “Deep” processing involves meaning-based, elaborative processing.
- LOP effects can be observed in everyday life situations. If you learn new information in a “deep” way by integrating it with previous knowledge and/or associating it with similar memories, you will likely remember that information.
- For example, if you learn about the biological mechanisms of emotions by trying to understand the content of different papers and integrate information from different sources, it is very likely that you will have solid and long-lasting memories about it (deep encoding). Instead, if you learn something without fully understanding it, the information will disappear quickly (shallow encoding).
Why can’t encoding and retrieval be seperated?
Scientists must assess how accurately
information is retrieved to find out whether that information has been encoded effectively (just like the memory tests we have just done).
What are the two types of retrieval?
Explicit
Implicit
