Q
  • time delay of neuroplasticity after brain damage leads to _____
A

compensaiont

17
Q

what principle says - training must be important
- motivation and attention lead to task engagement

A

salience

18
Q

how is neuroplasticity impacted by age

A

occurs more readily in young
- as we age, widespread neuronal and synaptic atrophy

19
Q

can older brains learn?

A

yes, but may be less profound or slower progression

20
Q

what principle says - plasticity in response to one training experience can enhance the acquisition of similar behaviors

A

transference

21
Q

what principle says - plasticity in response to one experience can inhibit the acquisition of other behaviors

A

interference
