Chapter 8 - Everyday Memory and Memory Errors Flashcards
Define autobiographical memory, which is a type of episodic memory.
-memory for your experiences in your life (think life story)
What types of memories occur during mental time travel?
-both episodic and semantic
Define autobiographical facts
-context-free knowledge of one’s own personal world (considered semantic memories)
What are some difficulties to testing autobiographical memory? (2)
-events are from the past, possibly long time ago
-it is hard to assess the accuracy
Since autobiographical memories are so difficult to assess for accuracy, what do researchers focus on instead? What’s a technique they us? (2)
-things that can be assessed including age, vividness, detail, emotional intensity
-diary
Describe the study by Cabeza et al., on autobiographical memory. (2)
-had participants take their own photos of the campus and put stock photos of the same buildings
-participants would have their own photos as part of their autobiographical memory, whereas the stock photos were not part of this memory
What brain structures were activated by both A-photos (photographs the students took) and the stock images?
-Structures associated with episodic memory and processing scenes (parietal).
What were the results of the study by Cabeza et al., on autobiographical memory? Specifically, the student’s own photos activated what thee brain structures? (3)
Their own photos activated brain structures associated with:
-processing info about the self
-memory for visual space
-mental time travel (hippocampus)
What was the most significant finding by the Cabeza et al., research study on autobiographical memory?
-that the hippocampus showed the largest difference in activation meaning that autobiographical memories seem to activate this area more than other types of memories
What events are remembered well? (3)
-significant events
-highly emotional event
-transition points
What is the autobiographical memory retention function?
-a graph that represents the number of autobiographical memories recalled over time
What effects can you see in the autobiographical memory retention function? (the graph) (3)
-childhood amnesia
-reminiscence bump
-forgetting stage
What is the emergence of autobiographical memories also known as?
-The offset of childhood amnesia.
What term describes the scarcity of memories from the first few years of life?
-childhood/infant amnesia
At what age do people have very few or almost no autobiographical memories?
-before age 3
What is a key methodological problem when studying autobiographical memory?
-There is no guarantee that participants are truly remembering the events (they may recall details from photos or others’ memories of the event).
How can researchers minimize errors in autobiographical memory recall studies?
-By asking about important childhood events that can be corroborated.
What did Usher & Neisser (1993) find about autobiographical memory recall before age 5? What did they find children do recall? (2)
-Relatively poor memory before age 5.
-very emotionally charged events, such as the birth of a sibling (though death of a family or a move are remembered less)
Why might the birth of a sibling be memorable?
-It often becomes part of a family story that is retold repeatedly, giving it more rehearsal
How does rehearsal with stories and pictures affect memory differently based on a child’s age?
-Rehearsal with stories and pictures tends to result in weaker memories for children age 3 or younger, but stronger memories for children aged 4 or 5.
Why might memories be weaker for children aged 2-3 when rehearsed with stories and pictures?
-Their memory is still fragile and easily confused with stories and pictures, which can obscure actual memories.
What are the three main explanations for the offset of childhood amnesia? (3)
-Brain development
-language development
-development of the self
Which areas of the brain are underdeveloped during early childhood, contributing to memory deficits?
-hippocampus and prefrontal cortex
How might the timing of different brain systems’ development affect autobiographical memory (AM)?
-Because non-declarative and declarative systems develop at different times, autobiographical memory may not fully develop until certain ages.
