Screening test estimates the risk of DS in a fetus, diagnostic test can tell whether DS is present 2. Diagnostic test are 99% accurate but are associated with miscarriage; screening test are cost effective and easy to perform but there is no definite answer B. The types of
At least 75% of the subjects gave the wrong answer to at least one question, although experimental error may have had some influence on this figure. There was no doubt, however, that peer pressure can cause conformity. It was debated whether this is because people disbelieve the evidence of their own eyes or if it was just compliance, that people hide their opinions. Follow ups to the Asch Experiment showed that the number of dissenting voices made a difference to the results, as did the forcefulness of the confederates. One incorrect confederate made little difference to the answers, but the influence steadily increased if two or three people disagreed.
The memory is said to be like a photo due to its unchanging nature and high levels of accuracy. The key ingredient to flashbulb memories is a high level of emotional arousal at the time the event was committed to memory. Evidence to support the idea of flashbulb memory comes from Brown and Kulik themselves. They looked at flashbulb memories of the assassination of Martin Luther King. Findings showed that 75~% of black Americans had flashbulb memories of the event compared to only 33% of white Americans.
Traditionally, most people believe that in order to be successful they must work hard, and once they are successful, they will be happy. Today we have the beliefs that if we can just find that great job or win that promotion, happiness will follow. This theory may be the cause of many people leading unhappy lives. The Happiness Advantage: the Seven Principles of Positive Psychology to Fuel Success at Work by Shawn Achor a psychologist and former professor at Harvard shows how positive psychology research has proven the complete opposite. Achor provides stories and case studies from his research among many Fortune 500 companies and executives in 42 different countries, to explain how we can reprogram our brains to become more positive to gain a competitive edge at work.
The task was to match and pair words from a list of four. The learner was attached to electrodes and the teacher was instructed to administer shocks each time an incorrect answer was given. The shocks started off at 15 volts and incremented in 15 volt stages up to 450 volts. When the teacher refused to administer a shock he was prodded by the experimenter. The findings show that around 65% of teachers continued to the highest level of 450 volts, all the participants continued to 300 volts.
The results suggested that the attractiveness halo effect does not occur for male authors. Do physically attractive people have unfair advantages? An accumulation of contemporary research suggests that they do (Berscheid & Walster, 1972). Of particular interest is a set o f experiments which suggests that attractive people receive superior evaluations for behavior comparable to that of less attractive individuals (Clifford & Walster, 1973; Landy & Sigall, 1974). These results are discouraging because they imply discrimination in the evaluation of school and job performance (Berscheid & Walster, 1972; Dipbaze, Fromkin, & Wilback, 1975) as well as in judgments concerning moral or legal transgressions (Dion, 1972; Sigall & Ostrove, 1975).
All Pendulums Eventually Come to Rest with the Lighter Ones Coming to Rest Faster Galileo noted that the lighter pendulum comes to rest faster than heavier pendulums. As a test of his observation, two pendulums, nearly identical except for their bobs of different weights (cork and lead), were released at the same time and height. It was pulled back about 5 degrees, the cork bob came to rest while the lead bob was still moving. More trials were done and it revealed that same agreement with Galileo’s observation (Morgan,
According to scientists even though excessive worry has been generally considered a negative trait and high intelligence a positive one, worry may cause our species to avoid dangerous situations, regardless of how remote a possibility they can be. To indicate these results an experiment has been conducted where 44 people, 26 diagnosed with anxiety disorders and 18 healthy people, were asked to give an IQ test along with a questionnaire to assess their level of anxiety. During the test researchers
This makes laboratory experiments highly reliable as they are replicable. The laboratory experiment has major advantages as the method can be used to establish cause and effect relationships. For this reasons positivist sociologists use laboratory experiments as they favour a more scientific method. Positivist sociologists however also acknowledge the short comings of laboratory experiments, such as, it is often impossible or unethical to control the variables. Also their small scale means that results may not be representative or generalisable to the wider population.
Team member connected through only telephone calls. 10. Effectiveness of team in achieving the goals The lecturer asked the students to get into groups of four members for the presentation and after the presentation by the effectiveness of the team work; the team was graded with overall Distinction. And in the individual grading I was graded a Distinction. The lecturer after that told everyone their feedback on how they have performed and in what areas they should improve to succeed in the next presentation.
