Part I - Illumination Experiments (1924-27) These experiments were performed to find out the effect of different levels of illumination (lighting) on productivity of labour. The brightness of the light was increased and decreased to find out the effect on the productivity of the test group. Surprisingly‚ the productivity increased even when the level of illumination was decreased. It was concluded that factors other than light were also important.

Stanely Milgram created an experiment involving Yale students to injure a third party using electric shocks and studied how many students would follow orders and go along with the experiment. The experiment consisted of two people‚ a leaner and a teacher. The teacher would be placed at a table containing many different buttons and switches that were labeled from slight shock to severe shock. Then the learner‚ who was an actor‚ was strapped down to prevent excessive movement. He is instructed that he

Dutcher 1 English 1013 10/18/10 In nineteen sixty-three‚ Stanley Milgram conducted an experiment on obedience to authority figures. It was a series of social psychology experiments which measured the willingness of the study participants to obey an authority figure who instructed them to perform acts that conflicted with their personal conscience and confronted them with emotional distress. The experiment resulted in twenty-six out of forty of the participants

The effect of varying temperature on thee Rennin enzyme Abstract The purpose of this experiment was to see what affect different temperate had on the reaction rate of the enzyme rennin. The experiment was performed by placing test tubes filled with renin and milk into water bath which was heated or cooled to one of the temperatures trialed. The hypothesis justified because it found because it though data that the enzyme reacted faster with the 45° temperate because it was

Intercontinental University Aspects of Psychology Individual Project # 2 Experiments and Adaption July 30‚ 2012 ABSTRACT This paper is explaining five experiments; the process and results. It talks about sensory adaptation and how adaptation is evident in each of the experimental results. It also provides a comprehensive description of the sensory systems in the experiments that I performed. Before starting the four experiments‚ I had to remember that I had to keep in mind that there are five

starch). Beta glucose forms chains with extra hydrogen bonds on top of each other‚ making extra-tough microfibrils that cannot be digested by most organisms. Proteins accomplish many different tasks‚ including structural support‚ storage‚ transport‚ movement‚ and defense against foreign substances. One noteworthy type of protein‚ called an enzyme‚ acts as a catalyst‚ speeding up chemical reactions in the cell. All proteins are composed of the same set of 20 amino acids‚ and each amino acid differs

The purpose of this experiment was to test the tonicity of potato cells. The potato cells were placed in different test tubes with water and were left there for 15 minutes. The percent change in mass is then used to determine if the cells lost or gained water‚ therefore determining the tonicity of the cell. Although it was a brief short time‚ the final results showed that the more water the potatoes were placed in‚ the more hypotonic the potato becomes. Tonicity is stated to be the state of a solution

The importance of following chain of command at the workplace In a company‚ chain of command means the order of authority level from a business owner or CEO to a front line employee. It is the structure where you report to your upper in an appropriate authority order. It is a very effective tool that helps keep the order in any size business. For example‚ if you are a bank teller and you have a scheduling issue‚ you should discuss it with your supervisor rather than with their upper up. Sometimes

Daphnia‚ also known as the water flea are planktonic crustaceans that are found in lakes‚ ponds‚ and streams. They received “their common name from their jerky movement through the water” (Clare). They are also “very small‚ usually 2-5mm long‚ with an overall shape similar to a kidney bean” (Elenbaas). Daphnia play an important role in the freshwater food chains and serve as food for other freshwater organisms such as fish. They are also commonly used to test for chemical toxicity in water. Since
