Answer to Question #188324 in Psychology for Nana

Question

Several researchers want to study the effect of exercise on visual perception. Each decides to use
a different method in their study. Researcher A assigns participants to one of two groups,
exercising for 10 or 0 minutes, and then records their performance on a task designed to measure
visual acuity. Researcher B decides to use the same task to measure visual acuity performance
from professional athletes vs. college students who do not play a sport. Researcher C asks a sample
of students from a university to report the number of hours per week they exercise, then looks at
the relationship between this measure and their performance on the same visual acuity task.
Name the kind of method used by each researcher:
a) Researcher A ________________
b) Researcher B ________________
c) Researcher C ________________
d) Which researcher (A, B, or C) can make the strongest claim about whether exercise is causally
responsible for a difference on the visual perception task?

Answer 1

Significance of Exercise on Visual Acuity

Physical exercise ,maintained balanced diet are the best and natural methods of enhancing performance on visual acuity.In the methodd of exercise, it is most importantly cardio exercise which is significant and has positive influence on visual acuity of a person .According to the research that was conducted, the strategy used by researcher B is likely to give more accurate results than the strategies used by the other researchers. Generally, physical exercise ensures maximum blood flow in the retina , optic nerve, hence improving the whole aspect of health and vision. However, this effect is not realized instantly or after a short period of time hence rendering the strategy of researcher one less effective. On the other hand, researcher B’s strategy of comparing visual acuity between athletes and college students who rarely do exercise will give reliable results because the athletes who do exercise daily will obviously have better visual acuity in comparison to college students.
