Bias: Motor Control and Favorite Color

Abstract What is your deary warp and why? Do you think that simple tasks might be biased by your preferences? Find protrude in this apprehension project if your seeming preferences leave behind bias your fine motor skills when doing quick, repetitive tasks. Objective In this science project you will test whether color preference will affect repetitive tasks that bespeak fine motor coordination, like picking up small objects very quickly. Do Preferences Bias Our Choices? approach What does it mean to have a preferred color?It may be something that you shoot for no goodness reason, other than the fact that you like it. You may have some kind of emotional reason for choosing a certain color. Can colorpreference have biological origins? When we see a color, it is interpreted in our reason by the visual cerebral mantle, where different groups of neurons are stimulated. The differential excitant of neurons within the visual cortex might lead to color preferences. Do these pre ferences affect other brain functions, like our behavior? Our brains in addition coordinate the movements of our muscles.This occurs in the motor cortex of the brain. If you play sports or video games, you know that one assistive skill ishand-eye coordination. This means that the different regions of your brain function well together, allowing you to be well-coordinated. When you catch a fast-moving ball, your eye tell the brain where the ball is, and then the brain tells your arm and hand to catch it. If these two areas of the brain can coordinate complexmovementsand behaviors, then 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 instrumentalists to quickly choose different- glowering M&M candies from a bowl. Will their choices reveal their color preferences? Terms and Concepts To do this type of science project, you should know what the following terms mean. Have an adult hel p you search the Internet or seduce you to your local library to find out more. * Preference * Hand-eye coordination * Movement * Bias * Visual 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&Ms your participants pick up? * Are visual targeting and hand-eye coordination biased by our color preferences? Materials Buy2 14-oz bags or 1 23. 1-oz bag of MMsand con viewr out 50 of for each one color, then compound those in a bowl. * Buy2 14-oz bags or 1 23. 1-oz bag of M&Msand count out 50 of each color, then combine those in a bowl. * Dry measuring cup (if you bought each colored MMs) * Large bowl * Several participants (at least 12) Sandwich baggies (one for each participant) * Permanent markers * science lab notebook computer * Graph paper Experimental Procedure 1. Depending on which method you selected in the Materials and Equipment list, portion your M&Ms into the large bowl. 2. Ask your first participant to pick out MMs 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 figure of M&Ms on the table.When you see that the participant has pulled out 20 MMs, 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 MM is and bring out it on the baggie with a permanent marker. 4. Replace the MMs that the participant removed with the same-colored M&Ms that the participant took from the bowl. For instance, if he or she removed three red and five night brown MMs, replenish the bowl with three red and five dark brown M&Ms, not from the participants sandwich baggie. . Repeat steps 2 and 3 for all of your participants, replenishing the bow l with the same-colored M&Ms as each participant removed after every trial. 6. Be sure that you have written each participants favorite color oneverybaggie If you forgot to write this down, the entropy cannot be used and the contents mustiness be disposed of. 7. When you have collected data from several participants, sort your baggies into groups by the favorite color written on the baggies. 8. Starting with one Favorite colour in group, tally the numbers of each colored M&M in the bags.Then move on to the next Favorite Color and do another(prenominal) tally, until you have tallied the numbers of all of the colored M&Ms picked for each Favorite Color category. Record your data in a data table like the one below in your lab notebook Participant Number of MMs Chosen of Each Color Total Number of M&M s Chosen rosy-cheeked chromatic Yellow Green Blue Brown Red Orange Yellow Green Blue Brown 9. To be able to compare numbers between categories, you will need to normalize the data.Do this by calculating percentages of each color picked for each Favorite Color category. premiere add together the total number of MMs chosen for each Favorite Color in each row and insert that in your data table, like the one above. Then expect the percentages in a bleak data table by dividing the number of MMs chosen for a single color (from theNumber of M&Ms Chosen of Each Colorcolumn) by the total number of MMs chosen (from theTotal Number of M&Ms Chosencolumn), and then multiplying your answer by 100.The new data table should look like this Favorite Color MM Percentage of MMs 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 exercise a graph called ahistogramfor each 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 bottom of the graph (x-axis), write the series of M&M colors. Draw a bar for each color up to the coordinated 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
