What is the Brown-Peterson Task?
A cognitive exercise used for testing the limits of working memory capacity
What was the purpose of the Brown-Peterson Task?
to show how the passage of time will make you forget
What did the experimenter in the Brown-Peterson Task do?
asked the participants three words to remember, they then asked what those three letters were to see if the words are still present in their minds
The Brown-Peterson task is also known as what?
Decay
What is decay?
the loss of memory after time has passed, during which memory trace is not used
In the Brown-Peterson task, how long did it take for the participants to forget the letters they were asked to remember?
18 seconds
What did the participants in the Brown-Peterson task get asked at the end?
what letters they were told to see if they remember them and how fast it took them to forget
What did Keppel and Underwood (1962) study?
examined the effect of proactive interference on long-term memory,
What did Keppel and Underwood say about time?
the severe passage of time makes on forget information
What is proactive interference?
it is a particular task paradigm that has been used frequently to investigate semantic codes in primary memory is called
According to Keppel and Underwood, what makes a trial harder?
doing a previous trial makes the task harder on the next trail
Who conducted an experiment where the participants got 100 correct?
Keppel and Underwood
In the Keppel and Underwood trail, participants began to mix letters in the trail. Did proactive interference decline or go up?
the proactive interference declined
In other trails, letters of the previous trail began to do what?
intervene
What is the disruptive effect of new learning on the recall of old information called?
retroactive interference
Who found a clever way to demonstrate that primary memory in the Brown-Peterson paradigm is also susceptible to retroactive interference?
Judith Reitman (1971)
duration: 15 seconds
Instead of letters, Reitman used what?
3 words instead of letters
What percentage of participants pressed a button if they heard a tone within white noise in the Reitman task?
Study: book, shoe, boat
92%
What percentage of participants pressed a button if they heard “toh” among “doh” in Reitman task?
Study: Wall Pane Roll
77%
What percentage of participants pressed a button and said: “toh’s when hearing “toh” among “dohs” in the Reitman task?
70%
Where does proactive and retroactive interference exist in which aspects of memory?
short term memory (working memory) and in long-term memory
What is representation in terms of working memory?
the way in which you deform and represent information in your working memory
In the acoustic confusion, effect is where participants do what?
Participants made systematic errors, based on the sound of the letters.
Conrad (1964) said if STM representations are acoustic there should be more —
more memory errors when the list items sound alike
