outline the three stores of an individualsm memory
the 3 stores of an individuals memory are the sensory register and the short and long term memory
what type of encoding does the sensory register have
the sensory registers encoding based on enviornmental stimuli, primarily iconic (visual) stimuli and echoic (auditory) stimuli
what is the capacity of the sensory register
the sensory registers capacity is very large
what is the duration the sensory register can hold items for
for iconic stimuli the duration is 1/2 a second, for echoic stimuli the duration is 2-3 stimuli
what is the encoding of the short term memory
the encoding of the short term memory is primarily acoustic, based on sound
what is the capacity of the short term memory
the capacity of the short term memory is 7 + or - 2 items
what is the duration of the short term memory
the duration is 18-30 seconds
what is the encoding of the long term memory
the encoding of the long term memory is semantic, based off of meaning
what is the capacity of the long term memory
its capacity is believed to be unlimited
what is the duration the long term memory can hold items
the duration is believed to be a lifetime
what process will lead to us forgettign memories within the sensory register
the process by which this occurs is decay
what process’ leads to us forgetting memories in the short term memory
the process’ by which this occurs are decay and displacement
what process leads to us forgetting memories in our long term memory
the process by which this occurrs is known as interferance
what are the two types of interferance
the two types of interferance are the retroactive and proactive interferance
what is proactive interferance
proactive interferance is when old memories displace new ones
what is retroactive interferance
when new memories displace older memories
how do we transfer memories from the sensory register to the short term memory
we do this by paying attention
how do we maintain memories in our STM
we do this via maintanene rehearsal, simply reiterating the memory
how do we transfer memories from the STM to LTM
we do this via elaborative rehearsal, which is when we link memories to existing knowledge and provide it with meaning
how do we ensure memories in the LTM do not suffer from interferance
we ensure this via retreival from the short term memory
what did tulving state were the 3 stores within the long term memory
tulving stated the three stores within the LTM were the semantic, episodic and procedural stores
what are flashbulb memories
proposed by brown and kulik, it states people may remember specific events in great detail due to perceiving the event as shocking, important or emotionally charged
