Lecture Week 4 Flashcards
1
Q
Trace Decay Delay
A
- The longer the animal views the stimulus the higher the correct %
- The longer the delay between sample and comparison the lower the % correct
- Decay rates were consistently parallel over time meaning there were two factors making memory stronger or weaker
- Sample leaves a trace longer the sample on the longer the trace
- Trace decay is constant because the decay and the trace don’t influence each other
2
Q
3 types of Control Processes
A
- Maintenance Rehearsal - Repetition of an item - Atkinson & Shiffrin 1977
- Levels of Processing Theory - Craik & Lockhart 1972
3
Q
Levels of Processing Theory
A
- Craik & Lockhart
- Not about the number of repetitions but the quality of the control processes that help us remember it
- The deeper level of processing the more the remembering
- Put concepts into sentences as a deep process
4
Q
Working memory
A
- Baddeley & Hitch 1974
- A system with limited capacity for manipulation of stimuli, recall of memories, comprehension, complex cognition
- Stores and processes stimuli here so that we can carry out a task
5
Q
Working Memory Model
A
- Phonological Loop
- Central Executive
- Visuospatial Sketch Pad
6
Q
Recent Research - Central Executive
A
- Is actually many separate mental processes at once
- Evidence for this is found in brain injury.
- Lesions in certain areas of the brain disable some Central Executive abilities but not all of them
- This suggests that Central Executive exists in several different aspects of brain function
7
Q
Do Deaf People Have a Phonological Loop
A
- Deaf people have a sign length effect instead of word length effect longer signs require more processing that short signs
8
Q
Lee Brooks 1968 - Visuospatial Sketch Pad Interference
A
- Subjects who only had to call out their responses were faster
- Subjects who had to point as well as speak were slower
- A task with a phonological + Visuospatial element was quick
- Those with phonological + 2 Visuospatial elements was slow
- This show that visual and auditory information is processed separately.
