Q

Sensory memory: Iconic memory test

A

When a grid of letters is flashed on the screen for 1/20th of a second it’s difficult to recall individual letters. But if prompted to remember a particular row immediately it’s shown, participants will do so with high accuracy.

A

20 seconds for information. Memory is rapidly loss unless we actively do something with it.

Q

Extending duration of STM

A

Maintenance: simple repetition
Elaborative rehearsal: focuses on meaning and is more effective.

Q

Long term memory has a…

A

U-shaped pattern as function in possible series. Two components called the primacy and recency effect.

Q

Primacy effect

A

Information is transferred to long term memory. The effect is diminished if words presented at a higher rate.

Q

Recency effect

A

Information still in short-term memory.
Effect diminished if time delay before recall.

Elaborative

A

Focuses on information’s meaning, organizing, understanding, applying, relating, using imagery.

16
Q

Organizing information

A

Organizing information in ways that are meaningful can enhance memory.

17
Q

Hierarchy

A

Memory is enhanced by associations.

18
Q

Chunking

A

Combing items into larger units of meaning.

19
Q

Schemas

A

Are a mental framework and are a organized pattern of thought.

20
Q

Priming

A

To retrieve a specific memory from the web of associations, you must first activiate one of the strands that leads to it.

21
Q

Dual coding theory

A

Memory enhanced if youuse both verbal and visual codes

22
Q

Method of loci

A

Use imaginary physical environment and placement of images.

23
Q

Declarative LTM

A

Can be verbalized. Two subcategories:
Episodic: Personal experiences
Semantic: general factual knowledge

24
Q

Procedural LTM

A

non declarative memory, reflected in skills and actions, some classically conditioned responses.

25
Q

Explicit memory

A

Conscious or intentional memory.

26
Q

Implicit memory

A

Memory influences behavior but there is no conscious awareness. Priming tasks.

27
Q

Types of amnesia

A

Retrograde amnesia: memory loss for events before amnesia.
Anterograde amnesia: Memory loss for events after amnesia.

28
Q

Alzeheimer’s disease

A

Severe retrograde and anterograde amnesia.

29
Q

Encoding specificity principle

A

Memory enhanced when conditions present during retrieval match those present during encoding.

30
Q

Context dependent memory

A

Easier to remember something in same environment where encoded.

31
Q

State dependent memory

A

Ability to retrieve better when internal state at retrieval matches that at encoding.

32
Q

Mood congruent recall

A

Tend to recall information or events congruent with current mood.

33
Q

Interference theory

A

Proactive interference: Past material interferes with recall of newer material.
Retroactive interference: new information interferes with ability to recall older information.

34
Q

Hippocampus

A

Encoding station and converts short term memories to long term.

35
Q

Cerebral cortex

A

Encoding information from sensory registers and stores semantic information.

36
Q

Prefrontal cortex

A

Involved in functions of working memory.

37
Q

Long term potentiation

A

Process where communication across the synapse between neaurons strengthens the connection, making further communication easier.

38
Q

NMDA receptor

A

Receptor site on the hippocampus that influences the flow of information between neurons by controlling the initiation of LTP.
