Chapter 4

Question 1

Morphological vs functional change in plasticity

Answer 1

Morphological: LT structural change
EX. Strength

Functional: ST structural change
EX. Efficiency

Question 2

Learning vs memory

Answer 2

Learning: process that we acquire knowledge= ENCODING

Memory: product of learning process

Question 3

How to enhance memory

Answer 3

Arousal and attention
Associations made
Interest and emotion 
Learning context= problems w transfer 
EX. Rehab environment doesn't match real life environment

Question 4

Stages of memory (memory sys)

Answer 4

Sensory register
ST memory
LT memory

Question 5

Sensory register

Answer 5

Perception
Large capacity
Lasts 250s

Question 6

ST memory (working memory)

Answer 6

Limited capacity: 5-9 items
Temporary working memory
Attention and interest

Question 7

LT memory

Answer 7

Limitless duration
Events and general knowledge
Rehearsal to get ST to LT
Retrieval is LT to ST

Question 8

Localization of memory

Answer 8

Not local, all parts of neurons,brain and NS

Question 9

Neural plasticity

Answer 9

-Material property of neurons
-when stressed, plastic tissues permanently change= learning
EX. Increase in size of neurons

Makes signal more efficient btw neurons

Question 10

Plasticity and Nonassociative learning

Answer 10

Learning regards the property of a stim that is repeated and whether or not a response is habituized (decrease EPSP)or sensitized (increase EPSP)

Question 11

Plasticity and declarative learning

Answer 11

-conscious process, awareness and attention

Temporal lobe/hippocampus are used to est memory but not for storage

Question 12

** enhancing plasticity

MC or Matching
Neural plasticity short answer

Answer 12

Use it or lose it- functional degeneration of unused brain functions
Use it and improve it- enhance the function of specific brain functions with training
Specificity-nature of training=nature of plasticity
Repetition matters- needed for induction of plasticity
Intensity matters- needed for induction of plasticity
Time matters- plasticity occurs at different times of training
Salience matters- training must be sufficiently salient to induce plasticity
Age matters- more rapid when younger
Transference/interference
- plasticity to one training experience can enhance/interfere acquisition of other behaviours
