What is the magic number in terms of short-term memory?
Short term memory has three key aspects: The Magic number 7 (plus or minus two) provides evidence for the capacity of short term memory. Most adults can store between 5 and 9 items in their short-term memory. This idea was put forward by Miller (1956) and he called it the magic number 7.
What is our short-term memory capacity quizlet?
What is the capacity of our short-term and working memory? Short-term memory capacity is about seven items, plus or minus two, but this information disappears from memory quickly without rehearsal.
How many things can short-term memory hold quizlet?
most of short-term memory is encoded in auditory form. The capacity of short term memory is 7 items of information, plus or minus two items.
What is short-term memory capacity?
Capacity. The amount of information that can be stored in short-term memory can vary. In 1956, in an influential paper titled “The Magical Number Seven, Plus or Minus Two,” psychologist George Miller suggested that people can store between five and nine items in short-term memory.
How long is short-term memory quizlet?

How many bits of memory can be stored in short term memory?
Storage capacity associated with short term memory is very small. To put a number on it it can only store about 7 bits of information at a time. The duration/amount of time that we can store information is very brief, it is about 20 seconds.
How is short-term memory measured?
How can you measure and assess short-term memory?
- Sequencing Test WOM-ASM: You will see a series of balls on the screen.
- Concentration Test VISMEN-PLAN: A series of three objects will appear on the screen, and the user must remember the order in which they appeared.
Where is short-term memory?
Short-term memory primarily takes place in the frontal lobe of the cerebral cortet. Then the information makes a stopover in the hippocampus. A 2014 study published in Proceedings of the National Academy of Sciences found that a small number of neurons in the hippocampus may hold the memories of recent events.

What are the features of short-term memory quizlet?
what are the key characteristics of short-term memory? the capacity of short-term memory is limited and short-term memory holds information very briefly. the unlimited capacity memory store that can hold information over lengthy periods of time.
How long does short-term memory last quizlet?
The duration of short-term memory is only about 18-20 seconds. Rehearsal (repeating info to retain it longer) can increase the duration of STM. The capacity of STM was studied by George Miller.
What are the types of short-term memory?
There are two types of short-term memory:
- Auditory/ verbal memory: Auditory memory is the ability to take in the information that is presented orally, process it, retain it in the brain and then recall it.
- STAM may show up in judgement and understanding of such things as.
- The capacity of STAM does increase with age.
What is the typical duration of short-term memory quizlet?
–Short term memory, which has a much smaller capacity than sensory memory but a considerably longer duration in the range of 15-30 seconds. Unlike sensory memory, STM is capable of producing a behavioral output, such as repeating a phone number someone has just told you.
What is short-term memory in psychology?
Short-term memory refers to information that people can remember for a short period of time immediately after receiving it. People with short-term memory loss have problems remembering pieces of information they just received.
Why 7 is magic number?
There are many theories for this, among which, that seven (like three, another sacred number) is a prime number, indivisible; that our daily lives are organized around a seven-day week; and that seven is the limit to the amount of information we can process and remember at one time.
What makes a magic number?
In nuclear physics, a magic number is a number of nucleons (either protons or neutrons, separately) such that they are arranged into complete shells within the atomic nucleus. As a result, atomic nuclei with a ‘magic’ number of protons or neutrons are much more stable than other nuclei.
What is short-term storage in psychology quizlet?
