Psychology Quiz Unit 2 Flashcards
TOT Phenemenon
Tip of Tongue, occurs when we fail to retrieve info
What is Recall?
Recall involved 2 steps, 1 generation of possible targets and , identification of genuine ones
ex. test info, remembering
What is Recognition?
generally easier because the first step is already complete and one only has to decide if the info is correct
ex. list of names and recognizing
Why do we need Memory?
- academics
- skills
- stay alive
- behaviour and experience
- recognize familiar people
- enjoy, share and sustain culture
- build a sense of self
- beyond conditioning in learning from experience including ones past and from the experience of others
3 Levels of Memory
Encoding
Storage
Retrieval
What is Encoding
-the info gets into our brains to a way that allows it to be stored (senses/attention)
- we use our sense to encode and establish memory, our senses capacity has limits
What is Storage?
- the info is held in a way that allows is to remember
- the info is maintained over time, the amount depends on how much effort was put into encoding the info and its importance
- info can be stored for 4 seconds or longer
What is Retrieval?
- reactivating and recalling the info, producing it in a form similar to what was encoded
- we can bring the info to the conscious level
What is Selective Attention?
- focusing on one thing, eliminating all distracting factors
- meeting basic needs (hunger/thirst)
- observing the strange or novel (new)
- considering topics of interest (people, subjects, etc)
The Atkinson-Shiffrin Model
1) Stimuli are recorded by our senses and held briefly in sensory memory
2) Some of this info is processed into short term memory and encoded through rehearsal
3) Info then moves into long term memory, where it can be retrieved later

External Events
- Sensory Input
Sensory Memory
- Encoding (attention to important info)
Working/Short Term Memory
- Maintenance Rehearsal
- Encoding
Long Term Memory
- Retrieving (Backwards)
What does Automatic Processing mean?
Info skips all the way to long term memory
What is Sensory Memory?
- refers to immediate, brief recording of sensory info before it goes to short or long term memory
- lasts a second, 250ms to 2s for Auditory
- 250ms for Iconic
Sense Memory Name’s
Eyes - Iconic Memory
Mouth - Gustatory Memory
Ear - Echoic Memory
Smell - Olfactory Memory
Touch - Haptic Memory
What is the George Sperlings Experiment?
- exposed people to 1/20th second view of grid letters, followed by a tone which told them which row of letters to pull from iconic memory and recall
- 50% of the time, people recalled letters without tone
- 100% of the time, people called letters with tone
George Miller (1920)
- proposed that we can hold 7+/2 info bits
- more recent research suggest that the average, free from distraction, can hold about, 7 digits, 6 letters and 5 words
Lloyd Peterson and Margaret Peterson (1985)
- want to know the duration of short term memory
1) given triplets consonants
2) prevent rehearsing by doing distracting tasks
3) tested at times for recall - results, 12 seconds most memory of the consonants had decayed and could not be retrieved
