Q

Give five common methods for forming memories/remembering things

A

Maintenance rehearsal: repetition of information to keep it in working memory, and/or short-term and eventually long-term memory

Mnemonics

Method of loci: associating an item of information with a location

Peg-word system: Associating numbers with items that rhyme or resemble the numbers.

Chunking/clustering: grouping elements of a larger list into groups of elements with related meanings

Q

What is elaborative rehearsal?

A

One way to consolidate information to long-term memory. Association of information to knowledge already stored in long term memory.

Similar to self-reference effect.

Very long term memories are moved to the cerebral cortex (e.g. name, birth date. etc)

Q

What are the two types of long term memory and two subsets of declarative memories?

A

Implicit (nondeclarative/procedural - skills and conditioned responses)

Explicit (declarative): Divided into semantic (facts we know) and episodic (our experiences)

Q

Define the following:

  • Context effects of memory retrieval
  • State-dependent memory/effect
  • Serial position effect
A

Context effects: you can retrieve information better in the same context that you learning it

State-dependent effect: You recall information when in the same state (e.g. intoxicated) that you learning it

Serial position effect: You can recall the first (primacy) and last (recency) of information presented in a list

Q

What is interference in memory loss?

A

Proactive interference: Old information interferes with the learning of new information (e.g. difficulty remembering new address because used to old one)

Retroactive interference: New information interferes with recall of old information (e.g. a teacher forgetting old students news when learning new student’s names)

Q

What is a source-monitoring error?

A

Confusion between semantic and episodic memory

Details of an event are remembered but the context is confused (e.g. hearing a story that happened to someone else then recalling it happening to themselves)
