Memory
BRAIN PARTS
-
Hippocampus -structure located deep within the brain that has a crucial role in the consolidation of most of our memories.
-
-
its crucial in the consolidation of new semantic and episodic memories so that they are neurologically stable and long-lasting.
-
Cerebral cortex -outer layer of the brain involved in complex mental abilities, sensory. processing and voluntary behaviours
-
Cerebellum -the cauliflower-shaped structure located at the base of the brain that looks like a mini-brain.
-
ATKINSON-SHIFFRON MODEL
Sensory Memory -the entry point of memory in which the stimuli that bombard the senses are retained in their original sensory from for a very brief time.
-
Echoic Memory -auditory sensory memory for incoming auditory information that stores sounds in their original sensory for for about three or four seconds.
Iconic memory -visual sensory memory for incoming visual information that stores visual image.s in their original sensory for a third of a second.
Short-term memory - Short-term memory is a memory system with limited storage, capacity in which information is stored for a relatively short time, unless renewed in some way.
Chunking -chunking is the grouping or 'packing' of separate bits of information into a large single unit or 'chunk' of information.
-
-
Long-term Memory -Long-term memory stores a potentially unlimited amount of information for a very long time, possibly permanently.
Explicit -Involves memory that occurs when information can be consciously or intentionally retrieved and stated.
Episodic Memory -Episodic memory is the memory of personally experienced events. These memories often include details of the time, place and our psychological and physiological state when the event occurred. (personal experiences and events)
Semantic Memory -Semantic memory is the memory of facts and knowledge about the world. it includes our specialised knowledge of facts and knowledge of the kind learned in school, everyday facts and general knowledge and the meaningful words.
Implicit Memory - Implicit memory involves memory that does not require conscious or intentional retrieval. You are not aware you are remembering, nor are you necessarily trying to remember something you know you know.
Procedural Memory - procedural memory is the memory of motor skills and cations that have been learned previously. It involves memories of 'how to fo something'.
Classically conditioned memory -implicit memory of conditioned responses to conditioned stimuli acquired through classical conditioning
REHEARSAL
MAINTENANCE REHEARSAL - maintenance rehearsal involves repeating the information to be remembered over and over again. Maintenance rehearsal will work, it will increase the capacity of STM, but to make a lasting LTM we should learn it really well and elaborate on the information.
-
-
-
ELABORATE REHEARSAL - the process pf linking new information in the meaningful way information already stored in memory or with other new information to aid its storage and retrieval from long-term memory; compare with maintenance rehearsal

ALZHEIMER'S DISEASE -Alzheimer's disease is a type of dementia characterised by the gradual widespread degeneration of brain neurones, progressively causing memory decline, deterioration of cognitive and social skills and personality changes.
Symptoms -specific symptoms differ for each person. Early symptoms of the disease include memory loss, confusion, unusual irritability and improved decision making.
Forgetting -forgetting refers to the inability to retrieve or access previously store information at a particular time.
-
-
-
Diagnosis -no simple diagnostic test of Alzheimers disease can only make accurate diagnosis after death when autopsy is conducted.
-
-
Amyloid plaque -proteins that form among axon terminals and interfere with communication between neurons
Amyloid- amyloid is not normally in the brain and is neurotoxic 9posions brain cells interring with normal brain function and causes brain cells to die.
