Bean+Passing+Questions

Slide 1
• After embedding your graph into your wikispace, answer the following questions:  The number of bean passing changes per pass determining on what phalange/ finger combinations that are being used. Since we are not machines and are not programed with certain patterns when doing things, it makes it harder for us to keep the same constant. For example: when we are passing the bean it can eventually make us tired which would slow us down or if we start bringing our arm or wrist closer and closer during each test, it would make us go faster and faster. Either way we would not be able to keep the same constant. However, if you keep at least one of your phalanges for 3 trails straight, the same then the outcomes for using those phalanges could be very similar/ close together, such as for the first 3 bars from my datas bean chart average (**UR1**- UR2, **UR1**- UR3, **UR1**- UR5). They all kept within the range of 79- 87 passes, which are the 3 highest bars through out the 6 bars within the entire bean chart averages. All 3 of these bars have one finger that is the same for all of them, which is the UR1 finger- your thumb. Your thumb is one of your most important fingers because it is the finger that you use to help you hold onto things, pass things (like beans), and just use things in general like brushing your hair. You have adapted to having your thumb around and using that finger to do things, which is why for these specific 3 bars they have the highest amount of passes, becuase you are mostly used to/ have grown used to using your thumbs to pass things like beans.
 * 1) – How does the number of beans being passed change as your finger combinations change?
 * 2) – What are some conclusions you can develop from looking at this data?
 * 3) – What might 2 or 3 sources of error that occurred during this experiment?
 * 4) HOW DOES THIS LAB DEMONSTRATE “ADAPTATIONS”?

One conclusion is when having thumbs, they benefit you when holding and using things apposed to being thumbless. Another conclusion, is when being thumbless makes things harder for you to pick up apposed to if you were to have thumbs. For example, we can text and hold a brush alot better, faster and securely because we have opposable thumbs than any other living thing that is thumbless.

Sources of error that could have occurred during this experiment:
 * if you start going a little faster or slower than you did before (not keeping the same constant)
 * if you start switching up your paired (assigned) phalanges when your not suposed to (when you start with a certain pair of phalanges and end with another during the same trial)
 * if you drop the bean when you were passing it to you partner and forgot to restart that trial (one of the rules were to start over if you droped the bean and continue your trial from there)

The lab helped demonstrate "adaptations" by using opposable thumbs has an example. Humans, apes and monkies all have opposable thumbs and adapt to having them in regular everyday life. Other animals that are thumbless adapt to having no thumbs. The word adaptation is just another way of saying "to grow used to something".
