Storage
Rehearsal
Maintenance- repetition with little of no interpretation.
Elaborative- when the stimulus maybe linked with other information.
Retrieval- it is referred as retention of stored memory
Recall-ability to remember when asked
Recognition-ability to notice info
Relearning-a measure of how long it takes to learn something back from past knowledge.
Amnesia-inability to remember the information.
Retrograde-loss of memory were formed before the event
Anterograde- where you can't form new memories after the event
False memory-when our brain is traumatized, so cannot recollect memory right.
tragic event- This could lead into false sensations.
Eye witness testimony- primary example of it.
Common phenomenon observed
TOT- Tip-of-tongue phenomenon is like you experience of knowing something but being unable to access

Alzheimer's diseases is a progressive disorder which can affects memory, thinking, and behavior
Multiple Sclerosis- a chronic disease that affects the central nervous system causing poor coordination.
Biology of memory
LTP and Hipocampus-a stable facilitation of synaptic potentials after high-frequency synaptic activity.
LTP and glutamate-synaptic plasticity where a persistent strengthening of synapses based on recent patterns of activity occurs.
Technology by which we can check brain function
Functional MRI- how different region of brain are working.
Computed tomography of brain helps us to see any unusual damage to brain.
Memory overtime when you grow-up
Meta memory- Knowledge of our own memory
Knowledge and related inferential processes, spanning from simple types of perception to complex forms of thinking, are referred to as cognition.
