1. encoding – transformation of sensory data into a
form of mental representation
2. storage – keeping encoded information in memory
3. retrieval – pulling out or using information stored in memory
Recall = a task to produce a fact, a word, or other item from memory (eg. fill-in-the-blanks tests), based on expressive knowledge
explicit tasks –requiring a conscious recollection – we are to recall or recognize words, facts, or pictures from a particular prior set of items
implicit tasks – performance is assisted by previous experiences which we do not consciously try to recollect, eg. word-completion tasks (m_m_ _ _)
we perform better when the word has been presented recently (memory priming), even amnesiacs perform well on cued-recall tasks

competing information causes forgetting;
the ‘Brown – Peterson’ paradigm
Two kinds of interference (inhibition):
The Brown – Peterson task may actually involve both types of
Interference vs decay
Moreover, interference affects long-term memory as well.
The total-time hypothesis: the amount of learning depends on the amount of time spent rehearsing rather than on how the time is divided into trials. The time, however, should actually be used for rehearsing that enhances recall.
Maintenance rehearsal - repetitious rehearsal; temporarily maintains information in STM;
Elaborative rehearsal– more meaningful and more memorable- necessary to transfer info into LTM- one way to elaborate information is to organize it
