Week 3 chapter 6. Acquisition of Memory & Working Memory System Flashcards

repetition. Without deep Processing though, will not confer Long term memory
memory connections
links between pieces of information. Form during learning. Can activate during retrieval to aid remembering.
reactivate
stored information is re-visited
storage phase
memory held but not in active use

Sensory memory
Part of Brief memory in Modal Model. Consisting of raw sensory data.
Iconic Memory for visual data. and
Echoic Memory for auditory data.
Updated version of memory
Short Term Memory now = Working memory (reflects thought is more of a process than place).
short term vs long term memory
Working Memory:limited size, getting info in is easy, getting access to info is easy, contents are fragile.
Long Term Memory: enormous size, getting info in not easy, getting access to info sometimes hard, contents are less fragile.
Recency effect
Data being worked on is available for recall. Unless something displaces the data (new info coming in), it is readily available. ie Can usually recall the last few words in a word list.
Distraction Tasks will serve as new info coming in however, and will disable remembering last few words of eg word list.
Primacy effect
When given list of words to recall, can devote more attention to rehearsing for first few words, therefore might consolidate these into Long Term Memory, therefore likely to later be able to recall.
Primacy, if consolidated (ie in Long Term Memory) is not affected by Distraction Tasks
Long Term Memory Location
Long Term Memory seems to be located in Hippocampus,
and Working Memory in Perirhinal Cortex (shown in fMRIscans).
Digit Span
Method of measuring Working Memory capacity. Eg. How many items can one see/hear and recite back? Usually, is 7 +/- 2 chunks.
A CHUNK= 1 piece of info, which may be a number, a letter, a word, a sentence etc. If can form larger chunks, can in total recall more, but are still 7 +/- 2 chunks.
Operation Span
It has been shown that quite a large area of the brain may be involved in Working Memory, dependent upon tasks involved.
Operation Span = the capacity to juggle various different tasks in Working Memory. Test how much Operational Span on has etc by eg flipping between maths problems, recall words etc etc.
People with greater Operational Span (greater Working Memory) seem to have greater ability in reasoning, comprehension, multi-tasking, etc.
Reading span
way of measuring Operational Span, using reading tasks.
