Exam 3 - 5&6 Flashcards
Cognitive Psychologists
Researchers and professors
Focus on memory and attention
Clinical Neuropsychology
Work with patients
Diagnose
Memory
Information that has persisted over time
Attention
Focus
Encoding
Creation of memory content
Storage
Retaining encoded info in some form
Retrieval
Later activation of info in some way
Atkinson & Shiffrin
Multi-Store Model of memory
Multi-Store model of Memory
3 stores
Emphasis on attention
Sequential and Linear
Sensory
Not sensed, can’t be encoded, can’t be remembered
Confabulation
Misremembering
No incoming sensory info, brain fills in gaps
Partial Repeat Model
George Sperling
12 letters, asked one, say it, forget the others
Sensory Stores
Briefly records a large amount of sensory info for a short time
George Sperling
Partial Repeat Model
Short-Term Memory Store
More attention
Smaller number of things
Somewhat longer
Long-Term Memory Store
Rehearse
Retrieval over time
Big
Effortful Processing
Consciously focusing attention on something
Rehearsal Loop
Repeatedly retrieving info to re-encode it
The Testing Effect
Retain more when questioned
Activates retrieval loop
Four Major Changed to Model
- Attention as a dual process
- Short-Term to Working
- 2 categories of long-term
- At least 2 paths for long-term
Forms of Attention
Explicit and implicit
Working Memory
Limited capacity, limited duration mental space
Five processes
Automatic Encoding
Automatically form explicit memories
Priming
Internal or external cues impact what info is accessed which influences perception
George Miller
Magic number
7 +- 2
Goes down when distracted
Nelson Cowan
Real world situation for magic number
4 +- 1
Central Executive
Determines what info to keep using prior experience
Episodic Memory
Events
Autobiographical
Semantic memory
Meanings
Associations
Implicit learning/retrieval
Prior experiences influence current behavior
Procedural Memory
Memory for actions
Muscle memory
Daniel Schacter
Priming studies
Word/Sentence Fragment Completion
Word/Sentence Fragment Completion
Given letter, fill in word
Things before to associate
Long-Term Potentiation
Increased connectivity between 2 neurons
HM
Removed parts of Brian
Aware and could attend, no new memories
