Experimental Procedure
1. In this experiment, you will need number sequences for people to remember. Each number sequence should be composed of the numbers 0–9 and be seven digits long. You can think them up yourself, or use this random number generator on the internet.
2. If you choose to use the random number generator, use your browser to go to http://www.random.org/nform.html and fill out the form so that it looks like this:
3. Then hit "Get Numbers" and a new page will appear with 7 listed numbers at the top. To get new numbers you do not need to fill out the form again, simply click the refresh button on your browser window, and a new set of random numbers appears.
Sequence used for echoic: 5310496
for iconic: 2156839
4. Write the sequence on the index cards. Make sure it is the same combination so that the difficulty does not change. This will be the sequence for the visual test.
5. Write a second combination on another index card. This will be the one for the auditory test. The same combination will be used with every subject so that the difficulty doesn’t change.
6. You will also need a data table for your experiment. It should have a place to record the number of correct answers for each participant, and for each type of memory test:
7. Find a research participant, and ask them if they will take two memory tests. Then give them the two tests below:
a. To test someone's visual memory, show them a card for 30 seconds and time them with a timer. Take back the card and have them recite the alphabet. Then ask them to tell you what the numbers were. Write down how many numbers they got right. This will be their score.
b. To test someone's auditory memory, read them the sequence of numbers on a different card three times slowly. After you read them the numbers, have them recite the alphabet. Then ask them to tell you what the numbers were. Write down how many numbers they got right. This will be their score.
8. You will need to have a lot of participants for this study, so gather data from as many people as you can! When you are done, count up the total number of people who got each score on the test and make a frequency table:
Material List
Question: What kind of memory is more present in teens and does gender have any effect?
Independent Variable: Whether people are given visual stimulus or auditory stimulus.
Dependent Variable: The number of correct responses.
Hypothesis: Teenagers have a better visual memory than an auditory memory because with a visual stimulus, people get to see the information. While with an auditory stimulus, teenagers can confuse the information, or not hear properly.
