24 Questions
What was Hermann Ebbinghaus known for in the field of psychology?
Pioneering memory research
What was the main aim of Hermann Ebbinghaus' experiment?
To know how much forgetting happens after different periods of time
What type of stimuli did Hermann Ebbinghaus use in his experiment?
Nonsense syllables or CVC trigrams
What did Hermann Ebbinghaus use as the primary subject in his experiments?
Himself
What is forgetting, according to the text?
The inability to retrieve information from memory
What did Hermann Ebbinghaus do after presenting himself with a list of nonsense syllables?
He attempted to recall the syllables after different periods of time
What is the primary reason for forgetting according to the interference proposal?
Other information interferes with the retrieval of target information.
What is an example of interference?
Forgetting your old phone number because you learned a new one.
What is retroactive interference?
When new information interferes with the retrieval of old information.
Why can't the participant in the Brazil example retrieve the capital of Brazil?
Because the knowledge of Sao Paulo prevents retrieval.
What is the main difference between retroactive and proactive interference?
Retroactive interference occurs when new information interferes with old information, while proactive interference occurs when old information interferes with new information.
What is the purpose of dividing interference into two types?
To understand the mechanisms of memory loss.
What is the primary pattern demonstrated by Hermann Ebbinghaus' experiment?
A lot of information is forgotten rather quickly after study, but then the rate of loss slows.
How much of the information is forgotten 20 minutes after studying, according to Ebbinghaus' Forgetting Curve?
40% forgotten
What is the main idea behind the decay theory of forgetting?
Memories fade away with the passage of time if not revisited.
What can be inferred from the Ebbinghaus' Forgetting Curve?
People forget information rapidly at first, but then the rate slows down.
What is the primary reason for forgetting, according to the interference proposal?
Memories are lost due to interference from new information.
What can be concluded about the relationship between time and forgetting, based on Ebbinghaus' experiment?
The longer the time since study, the slower the rate of forgetting.
What is the primary cause of proactive interference?
Old information interfering with new information
What is the main function of consolidation in memory?
To strengthen memories over time
What is the role of the hippocampus in memory consolidation?
It is involved in the initial formation of memories
What is the condition characterized by an exceptional memory, as seen in Jill Price?
Hyperthymesia
What is the importance of sleep in memory consolidation?
It aids in memory consolidation
What is the proposed dual cause of forgetting, according to research?
Interference and consolidation failure
Study Notes
Why Do We Forget?
- Forgetting is a natural process that occurs when information is unable to be retrieved from memory.
- It is the inability to retrieve information from memory.
Interference Proposal
- Forgetting happens because other information interferes with the retrieval of target information.
- Example: Learning the capital of Brazil (Brasilia) and then learning that Sao Paulo is the largest city in Brazil, making it difficult to recall the capital.
- Interference can be broken down into two types:
- Retroactive interference: New information makes it difficult to recall previous (old) information.
- Proactive interference: Old information interferes with the ability to recall new information.
Lack of Consolidation
- Another proposed cause of forgetting is the lack of consolidation.
- Consolidation refers to the idea that memories continue to strengthen after they have been formed, making them more resilient to forgetting over time.
- Initially, memory storage in LTM relies on the hippocampus, but over time, memories are stored elsewhere in the cortical areas of the brain, allowing for more permanent storage.
- Sleep is important in aiding consolidation.
Hermann Ebbinghaus
- He was a German psychologist (1850-1909) and a pioneer in memory research.
- He conducted some of the most important early experiments in memory from 1880 to 1885.
- He conducted many experiments using himself as the primary subject.
- One of his experiments aimed to know how much forgetting happens after different periods of time had elapsed since learning.
Ebbinghaus' Forgetting Curve
- He demonstrated that the inability to retrieve information, or forgetting, follows a particular pattern.
- The forgetting curve shows that a lot of information is forgotten rather quickly after study, but then the rate of loss slows as the length of time since study increases.
- Immediately after studying, about 40% is forgotten, and after 20 minutes, about 55% is forgotten.
Summary
- Research suggests that both interference and consolidation failure contribute to forgetting.
