Transcript of Smells and Memory

Data Smells and Memory By: Mariann Bui & ABBY Brunner Hello When we started out, we both had different ideas of what we should do and how we should do it. we are students from McPherson Magnet School, in Orange, California. We formed a group consisting of eighth graders. The Question The Hypothesis About Us Research Do different scents such as Eucalyptus affect the human memory? However, we found a way to take our individual interests and combine them to create this project that we hope will help students around the world. We wanted to see whether we could use different scents to help improve someone's memory for things such as studying. If we were to somehow win we would love to go to a rewarding collage and become successful. If so does it positively affect our memory or negatively affect it? We believe that... if we use peppermint then our memory will improve using eucalyptus will neither improve or worsen our memory instead it will improve our concentration if we use oranges then
we will become distracted and it will negatively affect our memory As everyone knows... memory is very important to our lives. But, what is memory? Memory:
the mental capacity or faculty of retaining and reviving facts, events, impressions, etc., or of recalling or recognizing previous experiences. Previous research in this area has shown that lavender has impaired and worsened memory, and that rosemary has improved long term memory. We want to know which of the threes scents we have chosen will help us study the night before a test. Still they are not proven to help if you use them the night before a test. The 3 types of memory are:
Sensory Long- term And Short- term Sensory memory is memory brought through the senses. Using aromas we hope to improve the information retrieval process in memory. & Oranges Peppermint Experiment Observation Conclusion The result of our project supported our hypothesis in some ways and contradicted it in other ways. We believed that peppermint would increase our memory, which it did, but we also believed that eucalyptus would improve our concentration and do nothing to our memory, but instead it worsened our memory We also believed that oranges would have a negative affect on the memory, instead it increased our memory. Materials: 1. 4 Memory Games
2. Laptop (record data)
3. 4 Test Subjects
4. 4 timers
5. Peppermint Extract
6. Eucalyptus Leaves
7. Sliced Oranges Procedures: 1. Set up 4 memory games
2. Seat 1 person at each game
3. Choose one of three scents, or no scent.
4. Have each person start their timer and begin playing their memory game.
5. Once they have finished their game have them stop their timer.
6. When all subjects have finished record times.
7. Rotate subjects to a different board.
8. Repeat steps 3-7 for the rest of the scents.
9. Bring subjects to their original board.
10. Repeat steps 3-8 to collect data on whether or not the time of game was effected or not.

Amount of time each subject took to complete their memory game and the scent that they had used. Each scent is tested twice on the same subject to see how much their memory improved. Below shows the average percent of speed increase between the four subjects for each scent tested. While we worked on our experiment we timed the speed it took for each person to finish their game. We recorded that in the previous step. Subject one finished their puzzle with the greatest time difference during oranges, with a difference of 26 seconds. Subject two had their greatest time difference also with oranges, a difference of 24 seconds. Subject three had their best timing with eucalyptus, an overall difference of 33 seconds. Subject 4’s memory improved the most with peppermint, a difference of 29 seconds The data in the previous step shows that peppermint was the best choice for improving memory and eucalyptus was the worst choice. Long term memory splits into two parts, episodic and semantic. Sematic is the kind of memory used to store information, which is what we will be targeting. Information retrieval is one thing that is a part of being able to forget things. Forgetting something is possibly not being able to retrieve it. After conducting this experiment, a new question rose: Do different scents affect each individual differently or does a scent have the same affect on everyone? We wanted to see what the answer was to these new questions because our data showed us that some people had better memory on one scent while another person may have had worse memory on the same scent. We think that this will be useful because if scents turned out to affect people as a whole instead of individually be will be able to improve human memory.
