Summary
The Experiment Is there a difference between the reaction times of male and female students and male and female teachers? Introduction In reference to Luce (1986), reaction time refers to the time difference between the instance of change in an individual’s environment and the commencement of the person’s response (p…

Download file to see previous pages Noble et al (1964) denotes that males respond faster to responses than females (p. 945). In addition, Luchies et al. (2002) asserts that response is always high among the young individuals till the late twenties and reduces as the individual approaches fifty years to sixty years (p. 142). Through the experiment, we will identify the differences in the responses among different genders and age. Methodology and Procedure We will consider the responses of different individuals in order to come up with a typology that addresses the distinctions on how people respond to reactions. The experiment will involve the use of a sharp object that will be used to trigger a reaction on each individual. In reference to Kosinski (2010), an external body that comes into contact with the human skin causes an impulse in the nervous system and triggers a reaction. This experiment is aimed at showing how fast the individuals will react. Each of these individuals will be exposed to one prick at a time while holding a ruler on the other side. This is to allow the body nervous system to send only one impulse at a time. Kosinski (2010) asserts that this allows the body to react effectively. Exposure to several pricks will lead to a triggering of many responses and may take longer for the body to determine which response to carry out. The individual exposed to the prick is expected to drop the ruler once he senses the pain. The time differences on how each of the individual responds to the stimuli will be measured and recorded in a table. The time difference and the speed at which each individual releases the ruler will be calculated using the s = so + vot + ?at2 formulae. The time difference at which each individual releases the ruler will be recorded in the table below. The experiment will employ univariate analysis of descriptive statistics to test the hypothesis about the relationships or the differences in the population grounded on the measurements of the samples. Time by Student Time by Teacher Male Female Male Female The Sample The sample, as indicated in the objective of the experiment, will involve two factors that affect reaction times in individuals. According to Welford (1980), various factors affect an individual’s response to stimuli (p. 13). Sanders (1998, p. 23) assert that individuals respond differently to stimuli according to their age and gender. The experiment will use four students, both male and female, and four teachers, male and female. The Results After the experiment, the students showed a higher response than the teachers while male students and teachers had a higher response than the female teachers and students. Response Time by Student (seconds) Response Time by Teacher (Seconds) Male Female Male Female 0.12s 0.18s 0.18s 0.22s 0.16s 0.19s 0.185s 0.21s The Means are 0.14, 0.185, 0.1825, 0.215 seconds for male students, female students, male teachers and female teachers respectively. From the experiment, we can deduce that males have a lower reaction time than female, and as according to Rose et al (2002, p. 27), reaction time increases with an increase in ages. Though the experiment did not use a large sample, it gave us an idea on the factors that affect response to stimuli of individuals. However, the empirical assessment of individual response to stimuli obtained from this typology may require future additions. There is room for future research just like Whelan (2008, ...Download file to see next pagesRead More

1.1: Body’s homeostatic mechanisms: The homeostatic mechanism of the human body is the process of maintenance of the static or the constant situations or conditions associated with the internal environment of the human body. This natural process is liable of controlling the mineral, water, air as well as the temperature concentration in the fluids of the human body within the narrow limits related to the inside as well as the outside structure of all the cells of the body (Rozelle and Wathen, 1993, p.3).
