RESEARCH QUESTION: DOES THE CHANGE IN THE ANGLE OF VISION (FROM STRAIGHT TO PERIPHERAL) EFFECT THE TIME TAKEN TO DETECT MOTION AND COLOR IN HUMANS?

ABSTRACT:

The research question of my study is “Does the change in the angle of vision (from straight to peripheral) effect the time taken to detect motion and color in humans?”

25 students in the age group of 16-18 years were selected for the first experiment conducted for detecting color. This was performed with the help of an experiment online at the site www.humanbenchmark.com. A chart marked with different angles of vision (0, 30, 60 and 90) was placed behind the computer screen.

The student sitting in front of the screen had to click the mouse when the screen turned green and the time recorded was displayed. Another experiment with the same group of students was done to detect motion. A similar chart as above was placed on the wall and the student was asked to catch a 30 cm ruler dropped by another student at different degree of angles. The distance obtained was converted into time using an appropriate graph. A two-tailed ‘t’ test was conducted. The calculated ‘t’ values were found to be higher than the table ‘t’ value at 48 degree of freedom. So the positive hypothesis was accepted for both color and motion. Comparison of ‘t’ values for color and motion at all degree of angles shows that positive hypothesis can be accepted. When the angle changes from 0 to 90 the time taken to detect color and motion increases. This means that change from straight to peripheral vision leads to increase in time taken for detection of both color and motion. The time taken for detecting color is more than the time taken to detect motion at all angles of vision. This means that humans are able to detect motion better than color at all angles of vision (from straight to peripheral).

1.2: WHY I CHOSE THE TOPIC?

The human eye has always been a very intricate structure to understand and as a student of biology I have always wished to study the structure in detail. I have sought after finding out how such a small organ can be very vital for a human being and help them in their everyday life as it is estimated that 2/3rd[1] of the information registered in the brain is due to the eye and also to know whether seeing from the corner of the eye is possible and if it is so, to what degree is it possible.
