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.
