Week 9 Flashcards
Cognition
The processes involved in acquiring, storing and using information
- attention
- reasoning
- memory
- decision making
- problem solving
Memory
The process of encoding, storage and retrieval of information
Defining Memory
- Encoding
- Storage
- Retrieval
Memory - Encoding
- The process of getting information into memory
- Attention and Enrichment
Memory - Storage
- Maintaining the encoded information over time
- Sensory Memory and Short-Term Memory
Memory - Retrieval
- Recovering information from the memory stores
- Confusion and Recall vs Recognition
Memory Processes - Encoding
- Code and put into memory
- Acoustic Memory Codes
- Visual Memory Codes
- Semantic Memory Codes
Memory Processes - Storage
- Maintain in memory
Types of long-term memory
- Episodic
- Procedural
- Semantic
Memory Processes - Retreival
Recovery from memory Types of retrieval tests
- Recall
- Recognition

Types of retrieval tests
- Recall
- Recognition
Auditory Memory Code
Tunes, sounds we recognise like birds or running water
Attention
Focusing your awareness on a small range of available stimuli
Not all attention is equal . . .
The quality of the attention you pay does matter
Levels of Processing
- Shallow Processing
- Intermediate Processing
- Deep Processing
Shallow Processing
- Focus on physical features
- such as remembering a short list
- Occurs during maintenance rehearsal
- No focus on meaning
Maintenance Rehearsal
eg: chanting a phone number until it is dialled
Deep Processing
- Focus on meaning
- Is it useful in a particular situation
- Creating an image of the item
- Occurs during elaborative rehearsal
Elaborative Rehearsal
- Eg: Understanding the concept of conditioning
- relating it to something you already know
- Results in better recall
Structural Encoding
- occurs in shallow processing
- emphasizes the physical structure of the stimulus
- eg Is the word written in capital letters?
Phonemic Encoding
- Occurs in intermediate processing
- emphasizes what a word sounds like
- eg: does the word rhyme with weight
Semantic Encoding:
- Occurs in Deep Processing
- Emphasizes the meaning of verbal input eg: finish this _____________ .
Levels of Processing: Craik and Lockhart (1972)
Memory Storage
Keeping information in memory over time.
Episodic Memory
An event, as it happened
Semantic Memory
Generlised Knowledge
Procedural Knowledge
How to do things
Declarative Memory
- Semantic Memory - I know what a guitar is
- Episodic Memory - I remember buying my first guitat
Procedural Memory
- Remembering how to do things
- eg: I remember how to play a guitar
Information Processing Model of Memory
- Stimulus
- Sensory Registers
- Information lost
- Short Term Memory
- Information lost
- retrieval
- rehearsal
- Long Term Memory
- Retrieval
- Information lost
Sensory Registers
- One sensory register for every sensory system
- Iconic memory-visual information
- disappears in approx 1/2seconds
- Echoic store-auditory information
- seems to last about 4 seconds
Short Term Memory (STM)
- Holds a small amount of information (7 + or – 2)
- Holds for a short amount of time
- Chan be increased by process if chunking
- Limited duration of about 20-30 secs
Role of Memory in Rehearsal
- a term for the role of repetition in the retention of memories
- Involves repeating information over and over
- Attempts to process information and store it as a memory
Duration of Short Term Memory
- Less than 30 secs without rehearsal
- Rehearsal is the act of repeating information
- Repetition needs to be purposeful to keep it in STM
What is Chunking?
- Helps increase the amount of memory held in STM
- Chunk sizes increase with familiarity of the topic
