Long-term Memory: Systems and Processes (Pt2) Flashcards
What is believed about episodic memories when the hippocampus is not involved in storage or retrieval?
episodic memories become semanticized
What evidence supports the processing view of memory?
- individuals with developmental amnesia
- Jon suffered hippocampal damage (age 4) and got anterograde amnesia for episodic memory. Semantic memory, language development, school performance, and IQ were normal
What does the Levels of Processing theory propose?
the depth of processing affects how well information is remembered; deeper processing leads to better retention
What is the definition of the Levels of Processing theory?
the observation that how we encode information affects the likelihood of retrieval, rather than where it is stored or how long it is stored
What are the two types of rehearsal in memory processes?
- Maintenance Rehearsal: Keeps information active in short-term memory through repetition.
- Elaborative Rehearsal: Links new information to existing knowledge in long-term memory (meaning-based rehearsal).
What are the three types of questions used in Craik and Tulving’s (1972) experiments?
- Font (e.g., Are the words written in the same font?)
- Rhyming (e.g., Does this word rhyme with HOUSE?)
- Similar meaning (e.g., Do the words happy and glad have a similar meaning?)
Which type of processing results in better memory recall according to Craik and Tulving?
Deep
In Craik and Tulving’s (1972) experiment, which question had the higher percentage of correct recall of words?
when they were asked if the two words had a similar meaning
What are some limitations of the Levels of Processing theory?
1) Shallow processing can sometimes lead to better recall than deep processing due to context effects.
2) The theory does not adequately explain why some information is available but not accessible.
3) It may be overly simplistic and circular in its definitions (more of a framework, not a theory as it doesn’t predict anything).
How does the distinctiveness relate to memory?
also known as the isolation effect or von Restorff effect
- Items that stand out or are distinct from others (e.g., unique or unusual information) are more likely to be remembered
What is the role of elaboration in memory encoding?
creating meaningful links to new information, which enhances the depth of processing and aids in memory retention
What is forgetting things in LTM often caused by?
retrieval failure, information is available but not accessible
How does retrieval failure manifest?
- feeling of knowing (familiarity)
- tip-of-the-tongue phenomenon
- cued vs uncued recall (eg. Tulving and Pearlstone)
What was the primary focus of Tulving and Pearlstone’s 1966 experiment?
To compare memory performance in free recall versus category-cued recall conditions.
What were the results of Tulving and Pearlstone’s experiment regarding free recall and category-cued recall?
Participants remembered significantly more words when given category cues (75%) compared to free recall without cues (40%)
