Explanation of Long term memory Flashcards
Tulving made a distinction of different types of LTM what were these?
Deeclarative and procedural memory
What is declarative memory
Memory of meaningful events, like being taught how to drive
What is procedural memory
Memory on how to do things, you can forget when you were taught but not how to do it.
Tulving splits the declarative memory into 2 sub-types. What are they called?
Episodic and semantic memory
What is episodic memory
Responsible for storing information about events we have experienced
What is semantic memory
Storing information about the world. How things fit together
Nature of stored memories in semantic and episodic memories.
Semantic - things people have perfected as a result of learning e.g concepts, facts, work academic skills. (facts)
Episodic - weddings, graduations, embarrassing moments don’t get forgotten, stored in episodic memory. (events)
Time referencing semantic and episodic memories.
Semantic - not linked to a certain time, you can reference them without knowing when and where you learnt it.
Episodic - is linked to a time
Spatial referencing in semantic and episodic memories.
Semantic - it is fragmented, do not need to know the whole event
Episodic - you remember the whole event in one piece
Nature of retrieving semantic and episodic memories.
Semantic - context and cues not needed for recall
Episodic - recall is dependant on context or cues
Independence of each type of memory in semantic and episodic memories.
Semantic - can operate independently of episodic memory
Episodic - cannot operate without semantic memory. you need previous knowledge of events, objects and people to understand them
Strengths of theory
Distinction between episodic and semantic memories is supported by evidence from case fo HM
Describe the case of HM
His episodic memory was impaired due to brain damage. He had difficulty recalling events from his past. Semantic memory was fine. He didnt remember stroking a dog or that he owned a dog, but understood what a dog was
Weakness of the theory
Lack of control variables. Most studies involved people with brain damage. No knowledge of participants’ memories before the damage. Reduces validity.
Strength of the application of the thoery
Understanding of episodic/semantic memory allows real life applications.
