What is Memory and How Does it Work?

1. Explain sensory memory?
Sensory memory is when you use senses to store event or objects you saw in your memory. It is the first level of memory.
2. An example would be that I use my eyes in order to observe something and then store that image in my memory.When you see an object and then dissapears you stay with that image.
3.The capacity of sensory memory?
 Our brains can gather a lot of information but most of that information dissapears fast and just stays in our memory for a short amount of time. There is two sources for sensory memory:
-iconic memory (visual sensory memory)-less than 1 second
-echoic(auditory sensory memory)less than 4 seconds.
4.Concept of short term memory?
MEMORY BEFORE LONG TERM COMES IN AND GOES OUT IN HEAD BETWEEN 30 TO 40 SECOND THE MORE YOU ANALYZE IT IN SHORT TERM IT WILL STAY IN LONG TERM
5-What is the "magic number" as it relates to short-term memory and who conducted the experiment which established this measurement?The Magical Number Seven, Plus or Minus Two: Some Limits on Our Capacity for Processing Information. remember seven things dont remember more than 5.
6.What is chunking?
chunking refers to a strategy for making more efficient use of short-term memory by recoding information. It gathers pieces of information to remember it better and put it into one group instead of having them all seperated.
7.What has been determined to be the ideal size of "chunks" for both letters and numbers?
The size of chunks would be 2, 3, or 6 letters or numbers.
8.Which mode of encoding does short-term memory mostly rely on, acoustic or visual?
Acoustic
9.Explain the duration and capacity of long-term memory?
The capcity is unlimited because its been shown their is no limit to what we can store. The duration is permenent  meaning a lifetime.
10.Explain in detail the Atkinson-Shiffrin Model of memory?
Memory starts as stimuli that we sense some of it goes into short term, if hold on to it or reherse it in short term then we can move it to long term, so once it gets there that information stays.
11.Identify three criticisms or limitations of the Atkinson-Shiffrin Model of memory?
"The three-box model suggests that there is nothing in between short-term and long-term memory. The three-box model implies that there is just one short-term system and just one long-term system.The Atkinson-Shiffrin model does not give enough emphasis to unconscious processes."

12.Explain the Levels of Processing Model of memory?
first shallow processing that would be like maintenance when you reapeat things so that you dont forget them. deep processing is like elaborative rehearsal  is when you compare something you don't know  to something that you already know so that you recall it later.
13.What is maintenance rehearsal - give an example.
Maintenance rehearsal is when you reapeat something over and over again so that you dont forget them. When i say someones name over  AND OVER AGAIN IN ORDER NOT TO FORGET.
14. What is elaborative rehearsal - give an example.
WHEN i REMEMBER SOMEONES NAME BECAUSE ITS THE SAME AS MY FAVORITE SINGER.
Who developed the Levels of Processing Model and the concepts of maintenance and elaborative rehearsal?
Craik and Lockhart
