LTM |
capacity is generally hardly affected but the speed of retrieval of information seems to decline with age.
|
|
|
STM |
suggests that if a task is complex, age may affect our ability to complete the task as our working memory capacity (of 7±2 bits) is decreased. Hence, working memory effectiveness decreases as we age. |
|
|
Forgetting |
is the inability to retrieve previously stored information from long term memory. |
|
|
H.M Case study |
H.M was a man who had a portion of his temporal lobe removed to assist in preventing epileptic fits. He suffered from complete, permanent anterograde amnesia without changes to his sensory and short term memory capabilities.Therefore had difficulty encoding new information to be stored in long term memory. |
|
|
Organisation |
is important in the structure of storing long term memories. The more effectively organised, the easier it is to retrieve information to conscious awareness when requiredBetter organisation is due to better encoding and hence providing the information with more retrieval cues. |
|
|
State Dependent cues |
are internal psychological and physiological cues where the presence of information in a particular state where the memory was formed act as a retrieval cue to help access those memories formed in that state. |
|
|
Beta Amayloid plaques |
are fragments of the protein called beta amyloid which accumulate over time to form hard, insoluble plaques outside and around neurons, thereby inhibiting neural communication. |
|
|
Alzheimer Disease |
is a type of dementia characterised by the gradual widespread degeneration of brain neurons, causing memory loss, a decline in cognitive and social skills and personality changes |
|
|
Ebbinghaus |
wanted to explore the amount and rate of forgetting. He did this by testing his memory of nonsense syllables (consonant-vowel-consonant) which are equally difficult to learn and shouldn't have a specific meaning or personal association. |
|
|
Supression |
is a conscious process where the memory is forgotten by a conscious effort to keep it out of conscious awareness. |
