2. Scientific Question Which type of memory is most common? All information for this project was found at: http://www.sciencebuddies.org/science-fair-projects/project_ideas/HumBeh_p018.shtml Haahr, M. 2006. "Random Integer Generator" random.org [accessed J] http://www.random.org/nform.html

3. Research What is Memory? Memory: the capacity of the brain to recall or remember things such as facts, details, events, or even to recall past experiences. In this project, I will testing peers to see if they are have a visual or auditory memory.

4. Auditory Memory Have you ever been able to memorize lyrics to a song just from listening to it? That is auditory memory. Auditory memory are the things you remember from hearing them.

5. Visual Memory -This is the most common memory category. -Visual Memory includes photographic memory, eidetic memory, and spatial memory. -A person with a stronger visual memory can remember details in pictures, past events, and even writing selections.

6. Hypothesis If I test many different ages and gender on their memory, then my data will show that more people have a stronger visual memory. Variables -independent: taking the two tests -dependent: how many digits they get correct

7. Materials *computer with internet *index cards *timer

8. Procedures • In this experiment, you will need many number sequences for people to memorize. Each number sequence will include 7 digits of numbers 0-9. • If you choose to get this sequences from the internet, this is a random number generator.

9. Procedures Cont’d 3. After you click “get numbers” from the random number generator a new set of numbers will appear. 4. Write down the number sequence on each index card, until you have a deck of 50 sequences. 5. Next, create a data table and print it off. Your data table should look like this:

10. Procedures Cont’d 6. Next, find a research participant and ask them if they will take 2 memory tests. a. to test someone’s visual memory, show them a sequence card for 30 seconds and use your timer to time them. Take back the card and have them say the alphabet. After they recite the alphabet, get them to tell you what the numbers were. Write down the number of digits they got correct. This will be their score. b. To test someone’s auditory memory, read them the sequence of numbers on a different card 3 times slowly. After you read them the sequence 3 times, have them say the alphabet. After they complete the alphabet, ask them to tell you what the number was. Write down the digits they got correct. This will be their score. 7. Record the data on the table you just printed out. If you don’t know what the table should look like, see the previous slide.

11. Data Table This table shows the relationship between scores & visual and auditory memory. The scores represent the number of digits a person got correct in a 7 digit sequence. In the visual and auditory columns, it shows how many people out of 15 got each score.

12. Conclusion In this experiment, I learned that most people are visual learners. Out of the 15 people I tested, 12 people were as accurate or more accurate reciting the digits after looking at them. My hypothesis was correct; most people had a stronger visual memory.
