The Milgram experiment‚ as it is now called‚ was considered a turning point in social psychology and the science of obedience. In a new study from Poland‚ a group of researchers wanted to see if the premise held up. That is‚ 50 years later‚ would people still respond to an authority figure in the same way as they did in Milgram’s original experiment? "Upon learning about Milgram’s experiments‚ a vast majority of people claim that ’I would never behave in such a manner‚’" study co-author Tomasz

that if Daphnia are placed in differently concentrated solutions of barium and calcium chloride‚ then the highest concentration of calcium chloride would affect them the most because of the production of hydrochloric acid and calcium oxide from the mixing of water and calcium chloride‚ two very dangerous acids‚ with the highest concentration having the biggest chemical reaction. Within five minutes of putting the Daphnia into the 10 (ppt) solution of calcium chloride‚ one or more of the Daphnia died

In "Dr. Heidegger’s Experiment‚" by Nathaniel Hawthorne‚ the magic book and dust are symbols that help illustrate Hawthorn’s theme of how people should lock their past away and always work for the future. When the four guests drink the fountain of youth Dr. Heidegger is experimenting whether people have learned anything from their earlier years in life. Overall the reality of life will emerge and the choice of resisting or going with the flow will surface. One symbol is the magic book‚ which is

pressure. This can lead to heart and circulation problems. Hypothesis: Daphnia subjected to a caffeine solution will show a rise in heart rate as caffeine is a stimulant that speeds up the body affecting the nervous system and rate in which the nerve pulses are sent and received in humans. (Caffeine increases the heart rate of Daphnia. ) Null Hypothesis: There is no significant difference between the heart rate of Daphnia in distilled water compared to that in caffeine.

| Case Study/Reaction Paper | The Stanford Prison Experiment | | Reviewing and Analyzing: The Stanford Prison Experiment The Stanford Prison Experiment was conducted at Stanford University in California from August 14 to August 20‚ 1971. Led by psychology professor Philip Zimbardo‚ twenty-four male students whom were chosen out of 75‚ were randomly assigned roles of prisoners and guards‚ for an investigation into the causes of conflict between military guards and prisoners.

Topic: Millikan Oil-Drop Experiment The Millikan Oil-Drop experiment was the first experiment to determine the charge of an electron. In 1909‚ Robert Millikan ultimately came up with a way to determine this charge through finding the minute electric charge on a droplet from an oil mist. Basically‚ Millikan started with an enclosed chamber that had two flat plates inside‚ one with a positive charge and one with a negative charge. The portion is split up by the positively charged plate so at the beginning

caffeine concentration rises‚ so does the mean heart rate of daphnia. Risk Assessment: In this experiment there are the following risks both for the human that carries out the experiment and the daphnia: ← The human that carries out the experiment should be cautious not to touch the lamp with wet hands since it uses electricity. ← Also‚ be careful not to spill any of the pond water on the floor. ← As for the daphnia‚ there is a chance for them to die as when they are exposed to

Examine the problems some sociologists may face when using different kinds of experiments in their research (20 Marks) To have control over variables and the environment they are researching‚ sociologists often use laboratory experiments in research. Lab experiments are used to test a hypothesis in a controlled environment‚ by altering an independent variable to see the dependant variable being tested changes. Positivists favour this method of research as it is a more scientific approach to research

Solomon Asch‚ a social psychologist had a hypothesis and he decided to test an experiment based on his hypothesis. Asch’s hypothesis theory was... Would people still conform to the group if the group opinion was clearly wrong? Well‚ to test his theory he chose a simple and objective task with an obvious answer. A group of people sat at a table and viewed a series of cards‚ on one side of each of the card was a standard line and on the other side were three comparison lines. Now‚ the individual’s

The Effects of Caffeine on the Heart Rate of Daphnia This lab was designed to show how caffeine affected the heart rate of daphnia after exposing them to different concentrations of caffeine for ten minutes. Caffeine is a stimulant‚ which‚ in humans‚ causes heart rates and blood pressure to increase. Its effects range from mild alertness to heightened anxiety and body tension. We wanted to see if caffeine affected the daphnia’s heart rate in the same way. We filled three containers with three different
