Optometry Research Papers
The goal of my project was to discover if the majority of my subjects had the same eye and hand dominance. To test this I had my subjects do a quick test. First I recorded their hand dominance. Next, I tested their eye dominance. They made a circle with their thumb and first finger. With both eyes open they looked at an object on the wall and centred it inside the circle. Then they closed one eye, and then the other. When they closed their left or right eye they should have found that the object jumped outside the circle. If the object seemed to move when they closed their left eye, then they have left eye dominance. If the object moved more when their right eye was closed, then their right eye is dominant. I expected to find the vast majority …show more content…
Your brain builds up an image of the world using different views from your right or left eye. The majority of people tend to have a dominant eye so that even when both eyes are open, the dominant eye processes and transmits information to the brain a few milliseconds faster than the other, as said on the website sportsci.org. The scientific purpose of my project was to determine if the majority of the population has the same eye and hand dominance. This project relates to my future interests because I am very interested in Optometry. Optometry is the practice or profession of examining the eyes for visual defects and prescribing corrective lenses. I picked this project because it involved testing eyes, which is what optometrists do every …show more content…
Studies have shown that differences in hand/eye dominance do not correlate with performance differences in basic laparoscopic skills. Another study also shows that shooting a basketball is not conclusively affected by crossed hand-eye dominance. Experiments testing the accuracy of basketball players shooting the ball through a variety of visual stimuli showed that, individuals tend to adjust to whatever dominant hand-eye combination they possess. Shooting a basketball simply reflects their hand-eye skills in general. However it can affect your accuracy in archery. This is because the dominant eye will always command the sight line when both eyes are open. When the bow is sighted with the dominant eye, everything works as it should. The line-of-sight and the path of the arrow

    The purpose of this experiment is to determine the response time for dominant and non-dominant hand for visual stimuli, and using only dominant hand to test auditory and tactile response. Also, to test involuntary the response time for the reflex of the knee from calculating the distance. Based on my group hypothesis, we said that visual stimulus dominant hand had a faster response time than non-dominant hand because the dominant hand is use more often thus repetition creates stronger connection. For only dominant we said that auditory response has the fastest reaction time because the auditory stimuli gets process faster compare to tactile and visual that has to travel longer to reach frontal lobe for response decision. For involuntary response,…

    Does crossed hand-eye dominance affect free throw shooting in basketball? Hand-eye dominance and how it affects basketball shooting are the focus of what is expected to learn about. The idea of having a dominant hand (being left-handed or0 right-handed) is familiar to everyone. What may not be so familiar is the concept of a dominant eye. Most people are accustomed to using both eyes together, and don't think much about situations where it might matter if one eye is dominant over the other. When shooting free throws in basketball, players often hold the ball up at face-level when preparing for the shot. In this position, the ball can easily block (at least partially) the eye on the same side of the body as the shooting hand. For shooters with uncrossed hand and eye dominances, this would mean that the dominant eye was partially blocked. For shooters with crossed hand and eye dominances, this would mean that the non-dominant eye was partially blocked. Clearly, basketball players must use their vision to locate the target and judge distance and line before skills take over to send the ball on its way. Hand and eye dominance must work together to help ones score baskets. Crossed hand eye dominance alone will not help ones score, but with other factors involved, it might help one score a basket.…

    This study was conducted to find a relationship between handedness and hemispheric dominance. The participants in this investigation were all year 11 students in psychology 1A/B at Greenwood College. The data collected by the survey sheet was put into a table then graphed into two separate graphs; one graph for left and the other for right hemisphere dominance. The results that were found rejected the hypothesis of there is a relationship between handedness and hemispheric dominance. It seems that majority of people are just right handed and left hemisphere dominant. The study is very limited due to the ample size and all the uncontrolled variables left in the investigation. This study can be criticized as very unreliable because of its lack to control variables.…

    Although they had participants from varying ages (20 to 65 years old), there were only 15 participants in the first experiment which may be too small of a sample if they are trying to generalise the results to the whole world or even just to the United States of America where the experiment toke place. Furthermore, the research does not state whether there were equal amounts of males and females which could possibly make the results unreliable if one gender is more susceptible to change blindness. Finally, as the experiment was conducted on a university campus, all the student may be of a similar socio-economic group as university can be quite expensive. This may result in little to no participants from a lower social-economic group and is therefore not representative of the…

    Cranial Nerve Lab Report

    The oculomotor nerve is examined using three different procedures: one to test motor function, one to test pupillary constriction, and another to test accommodation (Howard Community College, 2016, p. 191). The procedure to test motor function involves having the test subject follow with their eyes either one’s finger or a pen that traces an H shape, as well as assessing the eyelid position to see whether it is normal or drooping (Howard Community College, 2015, p. 191). The procedure to test pupillary constriction begins with viewing the test subject’s pupil shape and size to see whether they are oval or round and to see if the right and left are of equal size (Howard Community College, 2015, p. 191). This test is followed by another that involves directing a pen light approximately twenty centimeters to the side of the eye into the test subject’s pupil to see if it constricts and if the constriction is consensual (Howard Community College, 2015, p. 191). Lastly, the procedure to test for accommodation is used to see convergence of the eyes and is performed by having the test subject follow a pencil that begins about one meter in front of them and moves closer until it is approximately three centimeters in front of their nose (Howard Community College, 2015, p.…
