Term
\f0\fs24 \cf0 Rehearsal
Definition
Is when the information is repeated many times making it more likely to be transferred to long term memory\
Term
Organisation
Definition
Involves the arranging of info into groups and categories as logical way too learn as long term memory store info in a Varity of group/sections and more effective transfer into long term memory.\
Term
Elaboration
Definition
Elaboration of the meaning is the process of making facts easier to transfer and store by building them into a story e.g. a name and associate with a mental picture of the person there behaviour\
Term
Serial position effect
Definition
When info is viewed in a sequence the 1st and last few piece of info are best remembered. As 1st few are remembered because there is not enough items to crowd it and the last have not been displaced from short term memory \
Term
Contextual cue
Definition
A cue is a signal or reminder, contextual means it relates to the conditions or circumstances that were present at the time the info was encoded and commuted to long-term memory. It is though this can be triggered off by impulses through a memory circuit.\
Term
Alzheimer\'e2 disease
Definition
Involves progressive loss of the memory. Changes in the limbic system and its lose of ablity to produce neurotransmitter acetylcholine.\
Term
Acetylcholine (memory)
Definition
Neurotransmitter involved in memory transfer\
Term
NMDA
Definition
A simple protein like molecule involved in the role of memory storage\
Term
Retrieval
Definition
The ability to gain access to stored information and the degree of accuracy with which we do so\
Term
Short term memory
Definition
Has linked capability and important in filtering out unimportant info\
Term
Memory span
Definition
Length of info retained for short tome is limited to 5-9 bits of info\
Term
Chunking
Definition
By grouping several smaller units into a single meaningful pic of information e.g break telephone number into 3-4 number sections.\
Term
Long term memory
Definition
Has an unlimited storage capacity and is capable of retaining info for a lifetime.\
Term
Declarative memories
Definition
Recall of personnel fact and recall of general fact and is associative with areas of the \
Term
Procedural memories
Definition
Mental skills reading writing and motor skills like how to ride a bike. The cerebellum is found to be vital for many of skills which invokes muscular co-ordination.\
Term
Limbic system
Definition
In core of brain closely connected to other vital structure such as pituitary which is responsible for hormonal activities and the frontal lobes which lead with conciseness though reasoning\
Term
Encoding
Definition
Is process of selecting what to remember from millions of sensory impulses received by brain every second and converted and stored varies types of encoding are used conveying sensory events into picture sound or word.\
Term
Storage
Definition
Involves keeping the memory in the brain and avail be for use for some times varies from second to lifetime\
Term
Memories from short term to long
Definition
by the process of Rehearsal, organisation and elaboration of meaning\
