How does Sight Affect Balance Introduction Do you ever want to hit that triple pirouette? Or hold your arabesque for over thirty seconds? In order to do both those things, you need to have great balance. My science fair project demonstrates the effect of sight and balance. My scientific question is: How does changing dancer’s eyesight affect their balance? I will be eliminating sight completely, create tunnel vision, exclude the use of their dominant eye, lower the amount of light, distort their vision, and flash strobe lights above the dancers. My control group will be several dancers without anything impairing their vision, and them balancing in sous-sus, with no shoes on. Sous-sus is a dance pose when one foot is on front of the other, and you are on the ball of your foot. My real world connection is to see what is the best way for dancers to balance with their sight being impaired. Scientific Concept My scientific concept is how sight effects balance. Balance is the equal distribution of weight. “Balance is controlled by the vestibular system, which includes the eyes, the inner ear, and other sensory systems of the body” (asha.org). The visual system interacts with the vestibular system by using the …show more content…
I think that the strobe lights will be the hardest to balance with because the brain will try to take in both the light and the dark and not be able to process it fast enough. Throughout this project, I will learn more about the eyes and vestibular system. I will learn that balance is very precise and is best in certain environments. I will learn that balance is not as easy as it looks and that balance is very important to everyday life. I anticipate other people to learn that balancing for a long period of time is a very difficult and depending on their environment, they could be making it easier or harder on
Although this may make the dancers leg possibly go hire, the dancer would not be executing proper technique for a battement. Thirdly a dancer would not be able to properly rise up on releve if he or she was susceptible to anterior pelvic tilt. Not only is releve a stance in dance that calls for balance, it is also a move that leads up to bigger things like turns or leaps. Going into anterior pelvic tilt when in releve would seriously make the dancer off balance, decreasing the amount of time she could remain on releve. As a dancer, I think about my pelvis as a bowl of soup. If the bowl is sitting up right, nothing is spoiling out. However if a dancer allows her pelvis (bowl of soup) to lean into anterior pelvic tilt the soup will spill all over the floor. The second cue I like to think about it head
If the ballerina has trouble with her feet or ankles, the studio has onsite physiotherapists to assist with the injury.

The effects of perceptual load on the occurrence of inattentional blindness were demonstrated clearly by experiment. In an experiment conducted by Finch and Lavie in 2007, participants were given identical series of central cross-targets with two arms of clearly different color (blue and green) and slightly different length. Participants were split in two groups, one performing an easy task (low load condition) and the other a harder task (high load condition). The group performing the easiest task only had to make color discrimination between the tw...
...en information. With the use of echolocation, whales and dolphins can communicate between individuals, hunt, navigate, and visualize their surroundings even though they can’t always see it. An organisms ability to adapt and survive and environment is known as fitness, and has been perfected by whales in such a way that they haven’t significantly evolved for about 33 million years. Scientists have been using this extraordinary sense of communication, and depiction to identify in humans, specifically blind humans, the ability to use this advanced method of environmental depiction, and how they have used it to not only see their surroundings, detect movements in surroundings, and use this skill not only to navigate by walking, but even use this to depict what their entire environment looks like, what it contains, and what materials are present in the environment.
The world only sees a small fraction of a dancer’s life. While a performance on a stage may look flawless, the amount of work put into making it look like that is completely underappreciated.
Studies using blind or blindfolded subjects have tested and proved the theory of mental rotation (Carpenter & Eisenberg, 1978). Carpenter and Eisenberg’s study, as well as many others which have studied mental rotation with a variety of variables (such as gender, dominant hand and intelligence), all essentially measure the effect of mental rotation through the time it takes for an individual to correctly identify whether or not an object is different, or if it’s simply the orientation that has changed (Silvia et. al., 2013). The way in which this is typically tested is by asking a subject to compare two objects (which can be 3-dimensional objects, 2-dimensional objects, or simply letters from the ...
Dance does not just consist of turning and jumping; balance is also a key aspect in every style of dance. For balance, in physics terms, the net force and net torque is zero otherwise the dancer’s momentum would change and they might fall or tip over. The net force causes the change in the dancer’s momentum and it consists of gravity, support from the floor, and the friction from the floor. Torque is defined as an off center force or forces which can cause the dancer to spin.

In our everyday lives, we almost take for granted this idea of balance or equilibrium that is maintained within our bodies. In general, no real thought processes are required. It is only when something is disturbed within our balance system that one is able to take notice of changes in the equilibrium. There may be several different factors that cause a disturbance to our bodies. One major area pertains to dizziness. Dizziness is found to be "the chief complaint in 8 million physician visits a year" (1). Vertigo is one type of dizziness, causing illusions of movement, that is being researched more and more today because of its widespread symptoms.
Your eyes contain the receptors responsible for sight, which is the most dominant sense in humans. These receptors or “sensors” receive information about the surrounding environment and pass this information to your brain through the optic nerve. Your brain rapidly processes this information and creates the images you see, which allows you to see stationary objects, as well as follow moving objects whether your head is moving or is stationary.
Despite the fact that ballet is a completely new challenge for me, I managed to learn the choreographies and movements. From the videotaped performance I was able to identify the dance technique aspects that need to be improved for further correction. Although several elements, such as turns, port de bras, spatial awareness, movement quality and dynamic range require work; there are also aspects that were improved through practice.
The concept of proprioception, as introduced in a lecture on perception by Jim Davies, is defined as knowing where your body parts are without physically seeing them. (base example). This can be used to analyze the particular problem of proprioception in relation to the writings of Oliver Sacks.
Visual system of the body. The visual system of body is mainly responsible for determining the orientation of a person. Eyes are responsible for giving 90% of information related to orientation. The contradictory messages by other parts of the body are overruled by those of the visual system because visual system is the most trusted sense of a human being (Jacobson, 2010). Although a pilot is flying an airplane in Visual Meteorological Condition (VMC), the visual senses help him or her to keep the airplane oriented to earth. Due to spatial disorientation, the visual systems could become compromised, which could lead to mistakes in the vision system (Wynbrandt,
A ballet dancer’s general intention when performing any piece is to convey a message to the audience. A message is relayed through the dancer’s strategic facial expressions and body movements. Each movement has a purpose in articulating the dancer’s energy, and confidence within themselves to express the emotions and inspire the audience (Lucas). A dancer’s energy and
