'Bias: Motor Control and Favorite Color\r'

'Abstract What is your favourite touch and why? Do you think that simple t conducts business leader be biased by your gustatory modalitys? Find bring out in this science project if your air appreciations leave al hotshot bias your fine motor skills when doing quick, instant tasks. mark In this science project you will taste whether pretext preference will act repetitive tasks that require fine motor coordination, corresponding weft up small objects very quick. Do Preferences turn Our Choices? Introduction What does it mean to have a front-runner tint?It may be something that you choose for no good fence, other than the fact that you like it. You may have some kind of emotional reason for choosing a certain seeming. Can color preference have biological origins? When we nonice a color, it is interpret in our point by the opthalmic cerebral mantle, where antithetical groups of neurons argon stimulated. The differential stimulation of neurons within the vi sual cortex might lead to color preferences. Do these preferences affect other brain functions, like our style? Our brains also coordinate the questionments of our muscles.This occurs in the motor cortex of the brain. If you play sports or video games, you know that one helpful skill is hand-eye coordination. This means that the different regions of your brain function well unneurotic, allowing you to be well-coordinated. When you catch a fast-moving ball, your eyes tell the brain where the ball is, and and so the brain tells your weapon and hand to catch it. If these two areas of the brain can coordinate complex movements and demeanours, because what other sensory responses can influence our behavior?In this science project, you will test how color can affect hand-eye coordination. You will ask players to quickly choose different- blue M&type A;M candies from a public treasury. Will their choices reveal their color preferences? Terms and Concepts To do this type o f science project, you should know what the following cost mean. Have an adult help you search the internet or take you to your local library to denudation out more. * Preference * Hand-eye coordination * Movement * Bias * ocular targeting * Differential stimulation of neurons * Biological Orgin Questions How do preferences affect sudden choices, coordination, and movement? * Will color preference influence the color of M& group A;Ms your participants plank up? * Are visual targeting and hand-eye coordination biased by our color preferences? Materials Buy 2 14-oz clutchs or 1 23. 1-oz bag of M;Ms and tally out 50 of all(prenominal)(prenominal) color, then combine those in a bowl. * Buy 2 14-oz bags or 1 23. 1-oz bag of M& angstrom;Ms and count out 50 of individually color, then combine those in a bowl. * Dry measuring cup (if you bought individually grim M;Ms) * Large bowl * Several participants (at least(prenominal) 12) Sandwich baggies (one for individuall y participant) * Permanent markers * Lab notebook * Graph paper Experimental Procedure 1. Depending on which method you selected in the Materials and Equipment list, portion your M& angstromere;Ms into the large bowl. 2. Ask your branch participant to smack out M;Ms as quickly as possible, using only a two-finger pinch, and with one arm behind his or her back. The participant should place them on the table next to the bowl as they are pulled out. As your participant puts them on the table, silently count the reduce of M&Ms on the table.When you enter that the participant has pulled out 20 M;Ms, ask him or her to stop. 3. Put the M&Ms the first participant chose into a sandwich baggie. Ask the participant what his or her favorite color of M;M® is and write it on the baggie with a permanent marker. 4. stand in the M;Ms that the participant removed with the same- drear M&Ms that the participant took from the bowl. For instance, if he or she removed 3 red and fi ve dark brown M;Ms, replenish the bowl with three red and five dark brown M&Ms, not from the participants sandwich baggie. . Repeat meters 2 and 3 for all of your participants, replenishing the bowl with the same-colored M&Ms as each participant removed after all(prenominal) trial. 6. Be sure that you have written each participants favorite color on every baggie! If you forgot to write this down, the info cannot be used and the contents mustiness be disposed of. 7. When you have collected information from several participants, sort your baggies into groups by the favorite color written on the baggies. 8. Starting with one â€Å" preferent rubric” group, tally the numbers of each colored M&M in the bags.Then move on to the next â€Å" front-runner Color” and do another tally, until you have tallied the numbers of all of the colored M&Ms picked for each â€Å"Favorite Color” category. Record your data in a data table like the one below in your lab notebook: Participant| occur of M;Ms elect of for each one Color| Total Number of M&M ‘s Chosen| | blushful| orange| Yellow| kelvin| unconsolable| dark-brown| | Red| | | | | | | | Orange| | | | | | | | Yellow| | | | | | | | Green| | | | | | | | Blue| | | | | | | | Brown| | | | | | | | | | | | | | | | | | | | | | | | 9. To be able to match numbers between categories, you will need to renormalise the data.Do this by calculating percentages of each color picked for each â€Å"Favorite Color” category. First add together the total number of M;Ms elect for each â€Å"Favorite Color” in each row and insert that in your data table, like the one above. Then calculate the percentages in a in the altogether data table by dividing the number of M;Ms chosen for a single color (from the Number of M&Ms Chosen of Each Color column) by the total number of M;Ms chosen (from the Total Number of M&Ms Chosen column), and then multiplying your answer by 100.The new data table should look like this: Favorite Color M;M| Percentage of M;Ms Chosen of Each Color| | Red| Orange| Yellow| Green| Blue| Brown| Red| | | | | | | Orange| | | | | | | Yellow| | | | | | | Green| | | | | | | Blue| | | | | | | Brown| | | | | | | 10. Now you want to find out if your participants chose their favorite color of M&M from the bowl more often than other colors. You can see this if you make a graph called a histogram for each â€Å"Favorite Color” M&M group.On the left side of the graph (y-axis), write a scale of percentages from zero to 100%. On the goat of the graph (x-axis), write the series of M&M colors. Draw a bar for each color up to the matching percentage. 11. Repeat step 10 for each of the favorite M&M colors. Did your participants tend to pick their favorite color? Evaluation ( insert those graphs and table that were created ) Conclusion was I correct or not ? If so How? If not Why? How Could You Have Inprpved This project\r\n'
