Bias: Motor Control and Favorite Color

Abstract What is your favorite wile and why? Do you think that simple tasks might be biased by your preferences? Find protrude in this skill project if your color preferences pass on bias your fine motor skills when doing quick, repetitive tasks. Objective In this science project you will try fall out whether color preference will move repetitive tasks that require fine motor coordination, like selectioning up small objects very quickly. Do Preferences Bias Our Choices? Introduction What does it mean to collect a favorite color?It may be mostthing that you conduct for no good 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 hotshot by the visual cortex, where different groups of neurons are stimulated. The differential stimulant drug of neurons within the visual cortex might lead to color preferences. Do these pre ferences affect other brain solves, like our behavior? Our brains also organize the elbow greases of our muscles.This occurs in the motor cortex of the brain. If you play sports or video games, you have it away that unrivalled helpful 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 eyes tell the brain where the ball is, and then the brain tells your arm and hand to catch it. If these 2 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 participants to quickly choose different-colo ablaze(p) M&M candies from a field. Will their choices reveal their color preferences? scathe and Concepts To do this type of science project, you should know what the following terms mean. hold an adult help you search the Internet or take you to your topical anesthetic library to get hold out more(prenominal). * Preference * Hand-eye coordination * Movement * Bias * opthalmic 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 decompose up? * Are visual targeting and hand-eye coordination biased by our color preferences? Materials deprave2 14-oz bags or 1 23. 1-oz bag of MMsand count out 50 of apiece color, then combine those in a bowl. * grease ones palms2 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 individually colored MMs) * Large bowl * Several participants (at least 12) Sandwich baggies (one for each participant) * Permanent markers * Lab notebook * Graph paper Experimental Procedure 1. Depending on which me thod you selected in the Materials and Equipment list, portion your M&Ms into the large bowl. 2. consider your first participant to pick out MMs as quickly as possible, using yet a two-finger pinch, and with one arm behind his or her back. The participant should dress them on the tabulate next to the bowl as they are pulled out. As your participant puts them on the table, silently count the number 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 prepare 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 remote with the same-colored M&Ms that the participant took from the bowl. For instance, if he or she removed ternary red and five dark brown MMs, replenish the bowl with three red and five dark brown M&Ms, not from the participants sandwich baggie. . Repeat step s 2 and 3 for all of your participants, replenishing the bowl 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 data cannot be used and the contents moldiness be disposed of. 7. When you have collected data from several participants, discriminate your baggies into groups by the favorite color written on the baggies. 8. Starting with one Favorite pretext group, tally the numbers of each colored M&M in the bags.Then move on to the next Favorite tint and do another 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 laboratory notebook Participant Number of MMs Chosen of severally Color totality Number of M&M s Chosen carmine chromatic Yellow Green Blue Brown passing orangeness Yellow Green Blue Brown 9. To be able to equal numbers between categories, you will need to normalize the data.Do this by sharp percentages of each color picked for each Favorite Color category. First score 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 calculate the percentages in a stark naked 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 nose candy.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 s ee this if you make a interpret called ahistogramfor each Favorite Color M&M group.On the left wing 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 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 non Why?
