The Memory Questions

1. Explain the concept of sensory memory.
Its the ability of retaining impressions of sensory information. There are 2 types of sensory memory; iconic, and echoic memory.

2. Give an example of sensory memory.
You lose concentration in class during a lecture. Suddenly you hear a significant word and return your focus to the lecture. You should remember what was said just before the key word.

3. What is the capacity of our sensory memory?
500 milliseconds.

4. Describe the concept of short-term memory.
short-term memory is the ability of holding small pieces of information in mind.

5. What is the "magic number" as it relates to short-term memory and who conducted the experiment which established this measurement?
7+or-2, George A. Miller conducted this experiment

6. What is chunking?
chunking refers to the strategy of using short term-memory effeciently

7. What has been determined to be the ideal size of "chunks" for both letters and numbers?
The size of chunks is 4+/-1

8. Which mode of encoding does short-term memory mostly rely on, acoustic or visual?
Its definently visual

9. Explain the duration and capacity of long-term memory
The long-term memory is infinite it can last until you die

10. Explain in detail the Atkinson-Shiffrin Model of memory.
The Atkinson-Shiffrin Model is an advantage of the multi store model. It can chunk information into smaller models of memory.

11. Identify three criticisms or limitations of the Atkinson-Shiffrin Model of memory.
- It explains allot about memory, but its just a "model"
- It distinguishes different forms of memory, but it does not take into account what information is presented
-The Atkinson-Shiffrin model does not give enough emphasis to unconscious processes.

12.Explain the Levels of Processing Model of memory.
The levels of processing effect refers to the memory recall of stimuli as a function of the depth of mental processing.

It contradicts Atkinson-shiffrin memory model in the representation of memory strength as continuously variable. Its divided into Maintenance rehearsal and elaborative rehearsal.

13. What is maintenance rehearsal - give an example.
Maintenance Rehearsal is the process of repeatedly verbalizing or thinking about a piece of information.

For example - late at night, you have been out partying all night, you get back home and you are hungry. you decide to order pizza. So you pick up the phone and call information to get the number of a local pizza delivery place. When the operator gives the number, you say the number over and over so that you don't forget it in the time it takes to hang up and dial the number.

14. What is elaborative rehearsal - give an example.
Elaborative rehearsal involves deep sematic processing of a to-be-remembered item resulting in the production of durable memories.

For Example - A new student arrives at a classroom you tell his name and try to substitute the name with something else to create a connection with the name instead of saying the persons name a million times.

15. Who developed the Levels of Processing Model and the concepts of maintenance and elaborative rehearsal?

It was developed by Fergus Craik and Robert Lockhart
