Investigation: The Stanford prison experiment was originally intended to run for a fortnight. However it lasted only 6 days and was ended earlier than initially planned due to the terrible living conditions and psychological problems that developed as the ‘inmates’ and ‘guards’ interacted.. The experiment was run by Philip Zimbardo‚ Craig Haney‚ David Jaffe‚ and W. Curtis Banks. The test subjects were young male college students that were chosen from 75 volunteers. The volunteers had replied to

In "Dr. Heidegger’s Experiment"‚ written by Nathaniel Hawthorne‚ Dr. Heidegger invited four of his elderly friends to his eerie study and asked them to help him in an experiment. He explained the experiment with an old‚ withered rose which he took from his magic black folio. He took the rose which he claimed was given to him fity five years ago by his now deceased fiance‚ and dropped it into a vase with water from the fountain of youth. His guests watched the rose turn back into a freshly-bloomed

hypothesis were tested A. A deficiency of either nitrogen‚ phosphorus or both nutrients will reduce the height of the cereal crop. B. Tiller counts of the plants deficient in nitrogen or phosphorus will be significantly lower than that in the control group and the plants lacking both nitrogen and phosphorus will have a further dramatic reduction. C. Root system development in plants deficient in phosphorus‚ a nutrient that promotes root growth‚ will be significantly reduced compared to the

Abstract: Asch (1951) conformity experiment was conducted to investigate the extent of social pressure from a majority group on an individual. Asch conducted this study because he disagreed with Sherif’s (1935) conformity experiment‚ which had a small light in a dark room that did not move but he wanted to see how social pressure might affect a participant answer. Psychologist had earlier discovered that a small light in a dark room appeared to be moving‚ this was an illusion. Asch disagreed with

Red Cabbage Indicator Aim – To create a pH indicator out of a red cabbage solution and to construct a basic pH scale to determine the pH of unknown solutions. Materials - • red cabbage leaves • 250 mL beaker • hotplate or Bunsen burner‚ tripod‚ gauze mat and bench mat • 10 test-tubes – equal size • test-tube rack Methods - Part A: Making the indicator 1. Tear up one or two red cabbage leaves‚ and place them in the beaker with enough water so that the cabbage is just covered. 2. Heat the beaker

Dr. Heidegger’s Experiment-by Nathaniel Hawthorne With reference to the story comment on the subject of the story. The story is based on the desire of human beings for everlasting youth. Youth comes in life like a short lived spring and vanishes leaving behind a lot of regret and sadness. Youth‚ which should be the time to make the most of life‚ is often sacrificed at the altar of recklessness and frolic. Yet‚ the question which arises in the mind of the reader is that‚ if given a chance‚

that the situation seemed to create the participants to act the way their behaviour did and it was nothing to do with individual personality. The experiment links into the Milgram experiment‚ in which ordinary people followed orders to give what they thought was electric shocks to people they could not see. Participants’ behaviour was slightly affected due to the fact that they were watched as opposed to a lurking variable (Hawthorne effect). This questions the reliability of the experiment and its
