COGNITION: PSYC-316 DISCUSSION #5
Learning objectives: By the end of this presentation you will be able to…
explain why LTM is important
define the serial position curve (SPC) and its components
explain how the SPC supports the distinction and interaction between STM and LTM
compare the predominant forms of coding in STM with the predominant form of coding in LTM
explain how release from proactive interference supports the use of sematic coding in STM
Introduction To LTM: STM vs LTM
I. The importance of LTM
LTM is more than an archive of information
it interacts with STM, providing information that aids in making sense of an ambiguous environment.

Introduction To LTM: STM vs LTM
Atkinson & Shiffrin (1968) eliminated the primacy effect by presenting all items quickly, forcing equal rehearsal (at zero) throughout the series. Therefore, the advantage to primary items is that they had entered LTM.
Glanzer & Cunitz (1966) eliminated the recency effect by asking participants to count backwards for 30 seconds after the last item. Therefore, the advantage of recent items is that they were in STM.

Introduction To LTM: STM vs LTM
There is an interesting story about the telescope. In Holland, a man named Lippershey was an eyeglass maker. One day his children were playing with some lenses. They discovered that things seemed very close if two lenses were held about a foot apart. Lippershey began experimenting, and his “spyglass” attracted much attention. He sent a letter about it to Galileo, the great Italian scientist. Galileo at once realized the importance of the discovery and set about building an instrument of his own.
Which of the following sentences is identical to a sentence in the passage and which sentences are changed?
He sent a letter about it to Galileo, the great Italian scientist.
Galileo, the great Italian scientist, sent him a letter about it.
A letter about it was sent to Galileo, the great Italian scientist.
He sent Galileo, the great Italian scientist, a letter about it.
