What Is Memory - How Does It Work?

Use the internet to research and answer the folowing questions: (DO NOT copy/paste!) Due Wednesday October 20th by midnight.

1. Explain the concept of sensory memory.
Sensory memory is the first level of memory, sensory memory retains the brief impression of a sensory stimulus after the stimulus itself has ended. (Luke Johnson)

2. Give an example of sensory memory.

3. What is the capacity of our sensory memory?
The capacity of the sensory memory can get a lot of things at a time, but it can go fairly quickly from the memory. They are two types the Iconic Memory that can go in less then 1 second, and the Echoic memory that can go in less than 4 seconds.  (Miguel Ham)
4. Describe the concept of short-term memory.

5. What is the "magic number" as it relates to short-term memory and who conducted the experiment which established this measurement?

6. What is chunking?
Chunking refers to the process of taking individual units of information and grouping them into larger units.
(Melissa Pineda)
7. What has been determined to be the ideal size of "chunks" for both letters and numbers?

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

9. Explain the duration and capacity of long-term memory.

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. (Alexandra Wagui)
11. Identify three criticisms or limitations of the Atkinson-Shiffrin Model of memory.
The sensory stores are sensory systems, not memory systems as most people think of the term "memory."
The three-box model suggests that there is nothing in between short-term and long-term memory. However, evidence shows that information can reside somewhere between the extremes of active attention and long-term storage. Memories can be "warmed up" but outside of attention. In other words, intermediate levels of activation are possible.
The three-box model implies that there is just one short-term system and just one long-term system. In reality, there are many memory systems operating in parallel (for example, different systems for vision, language, and odor memory). Each has short-term and long-term operations.
The Atkinson-Shiffrin model does not give enough emphasis to unconscious processes. Unconscious activation is shown with a tentative, dotted arrow. Modern researchers find that unconscious and implicit forms of memory are more common than consciously directed memory processes.  (Mene Simon)

12.Explain the Levels of Processing Model of memory.

13. What is maintenance rehearsal - give an example.

14. What is elaborative rehearsal - give an example.

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