Research
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.
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.
-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.
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
*computer with internet
*index cards
*timer
1. In this experiment, you will need many number sequences for
people to memorize. Each number sequence will include 7
digits of numbers 0-9.
2. If you choose to get this sequences from the internet, this is a
random number generator.
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:
Number of Correct Answers:
Visual Memory Test
Auditory Memory Test
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.

2 people with this score.
4
1 person with this score.
3 person with this score
5
1 person with this score.
4 people with this score.
6
No people with this score.
1 person with this score.
7
13 people with this score.
4 people with this score.
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.
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.
