Paul Fitts’ was the first to discover the relationship between the speed of movement and accuracy requirements. This has become one of the most fundamental principles of motor control. Fitts claims a relationship between task difficulty and movement time. He quantified task difficulty as “index of difficulty” which consists of the ratio of twice the amplitude over width of the target (2Amplitude/Width). This relationship states that when movement amplitude decreases or when target width increases movement time is shorter (Fitts, 1954). Fitts found that the relationship between amplitude and width was given by the equation: MT= a + b[log2(2A/W)]. The empirical constants a and b represent the y-intercept and the slope (Schmidt & Lee, 2011).…

III. Procedure- The first thing one must do to identify which substance is which is to calculate the densities. To do this, one must take the mass and volume of each individual substance. Starting with mass, one can use the triple beam balance. Make sure the balanced is zeroed. Once that is true, place the object onto the balance a carefully find the mass of the object. Repeat and record the results found of each individual substance. To find the volume, one can use the water displacement method. One will fill up a graduated cylinder with water to a specific amount. 20 mL is sufficient. Once completed, one will drop one of the substances into the graduated cylinder and record how far the water level rises. If it starts at 20mL and rises to 22mL then the volume of the substance is 22mL minus 20mL, so 2mL. Repeat and record the results found of each individual substance.…

The tooth formula is a shorthand technique that biologist use to keep track of the teeth on a particular jaw. The formula consisted of two lines, top jaw and bottom jaw, which were used to count how many incisors, canines, premolars, and molar teeth a species had. Species A, Odocoileus virginiaus (white-tailed deer), had a tooth formula of 0033/3133. On the top jaw, the deer had zero incisor and canine teeth but have three of both the premolars and molars. On the bottom jaw, the deer had three incisors, one canine, three premolars, and three molars. Species B, Canis latrans (coyote), had a tooth formula of 3142/3143. On the top jaw, the coyote had three incisors, one canine, four premolars, and two molars. On the bottom jaw, the coyote has three incisors, one canine, four premolars, and three molars. Both the deer and coyote skull were long and skinny towards the nose and mouth. The coyote skull had a much rounder nose than the deer. Species C, Homo sapiens (human), had a tooth formula of 2122/2122. On both the top and bottom jaws, there were two incisors, one canine, two premolars, and two molars. In comparison to the deer and coyote skull, the human was an outcast. The human skull was a short distance from the back of the skull to the front. The human skull was very different in bone structure and longer in height than the deer and coyote skulls.…

I. Purpose/Hypothesis: In this lab the subject will grip on a scale that measures the amount of force being put on it. We will observe the change in hand strength during continuous grip over time. Then we will also measure hand strength during rapid, repetitive gripping. I believe that hand strength will weaken during a continuous grip more than if you were to keep a repetitive grip.…

According to our results, the hypothesis would be true. Although, I reject the hypothesis. Some men can very well have a larger head size and be more intelligent than a woman, but same could be said for women. Simply measuring the circumference of one's head could never actually tell you how intelligent someone is. The best way to accurately say that men are smarter than women is to actually test their intelligence with a series of tests in different subjects such as Math, Science and History.…
