Rulers And Reaction Times Essays - Cognition, Mental Chronometry

Rulers And Reaction Times Essays - Cognition, Mental Chronometry Rulers And Reaction Times Rulers and Reaction Times Abstract The reaction time of ten subjects was measured. The subjects were asked to catch a ruler ten times under five different conditions. The first condition measured the subject's simple reaction time. Each further condition added an additional stimulus and the reaction times were measured. There was a clear increase in reaction time with the addition of further stimulus, however the expected result of a steady increase in response time with the addition of each condition did not occur. The third condition displayed the highest response time where as the final condition displayed the second lowest (after condition 1). Assuming that no design problems in the experiment affected the results, it cannot be concluded that cognitive processes occur in separate order and do not overlap. Given the average reaction time of condition five was lower than condition three, some cognitive adaption may have occurred to lower the response time of the subjects or another reason may exist. One aspect not c overed by the experiment, but important to the results was the error factor. Pre-guessing the experimenter caused a high rate of error, however it lowered the overall results. Why measure response times? As the world moves forward with technology, increasing pressure is placed upon humans to be quicker, be smarter and to operate more efficiently. As the population increases systems are being put in place to reduce incidences and accidents occurring. An example of this is a study conducted by Cameron, 1995 examining the influence of specific light colors, motor vehicle braking and the reaction time of the drivers to these specific clouds and conditions to avoid rear end collisions. Donders subtractive method holds that reaction times can be obtained by subtracting the simple reaction time; or subtracting type A from type B etc. (Cameron, 1995). Given this, it stands that the more stimulus provided (or thought processes required), the longer the response time of the subjects. This theory is tested in the measurement of ten responses to five test conditions. The trial provides preliminary information to participants and it is expected that reaction times will be shorter than if no infor mation was supplied. (Rosenbaum, 1980.) Method Participants Ten participants were selected, four female and six male. Ages ranged from twenty-two to fifty three. All were fully able bodied and from English speaking backgrounds. Materials A plastic yard rule was used. The yard rule was six centimeters in width. Procedure Condition One The experimenter sat one subject on a chair and instructed them to place their arm out in front of them at a comfortable height. The yard rule was then placed between the subject's fingers at a height of 10 centimeters. The subject was then told the condition 1 (Appendix A) and given three trials. The subject then completed the ten tries at the condition and the results were recorded. All ten subjects were tested in the same manner. No abnormal results were obtained. Condition Two The experimenter sat one subject on a chair and instructed them to place their arm out in front of them at a comfortable height. The yard rule was then placed between the subject's fingers at a height of 10 centimeters. The subject was then told the condition 2 (Appendix A) and given three trials. The subject then completed the ten tries at the condition and the results were recorded. All ten subjects were tested in the same manner. An error rate and abnormal results occurred. Condition Three The experimenter sat one subject on a chair and instructed them to place their arm out in front of them at a comfortable height. The yard rule was then placed between the subject's fingers at a height of 10 centimeters. The subject was then told the condition 2 (Appendix A) and given three trials. The subject then completed the ten tries at the condition and the results were recorded. All ten subjects were tested in the same manner. An error rate and abnormal results occurred. Condition Four The experimenter sat one subject on a chair and instructed them to place both their arms out in front of them at a comfortable height. The yard rule was then placed between the subject's hands at a height of 10 centimeters. The subject was then told the condition 4 (Appendix

Have women achieved equality with men Essay Example | Topics and Well Written Essays - 1000 words

Have women achieved equality with men - Essay Example This is because it has always been one of the root causes behind the segregation between men and women. They both can work together to achieve their individual as well as collective goals yet the inequality arises all of a sudden and mars the whole phenomenon essentially. Plants and offices have of late been filled by women who were reckoned by the authorities as of less efficiency as compared to their male counterparts some years back. This has changed for the better and more and more companies in the world of today are recruiting female candidates for suitable positions within their staff. Apart from this positive change in mindset of the companies and businesses, there have been some pretty negative points attached to the same notion moreover. The top one of these aspects is the indiscriminate attitude of the staff towards the women working in the offices which has given birth to gender issues like the sexual harassment and racial vilification ones. In the present day workplace situation, white men have encouraged the selection of white women as well as minority group members but there is a totally different posture when the selection of black community staffing within these companies starts making waves. (Author Unknown, 2001) Gender is a word, which describes the characteristics and attributes that are culturally accredited with women and men. It is pretty different and distinct from sex, which in its own entirety means the physical characteristics that make up one biologically either a male or a female. Structuralists have been in agreement with seeing the gender as a product of universal cultural laws and customs of the languages that shape up a cultural utterance and assertion. Consequently, structuralism accounts for the gender that focuses on the traditional contour of the male hero as somewhat of an â€Å"active subject† and the heroine (from the female sex) as rather

Economic Globalization - Essay Example In general terms, economic globalization can be considered as an objective trend that features allotment of factors of production as well as transnational flow which have emerged as social productive forces have gained more strengthen. The need of the mature market to have constant expansion in both the international and the domestic markets lays basis for the economic globalization as a phenomenon. Economic globalization has caused a co-existence of challenges and opportunities and has resulted into many losses along with gains as will be shortly looked into in the following sections. Economic globalization is fairly much like the first industrial revolution. The first industrial revolution came as a precursor of the material prosperity. The first and foremost similarity between economic globalization and the first industrial revolution is that both have resulted into an immense and abrupt new era of social productive forces along with the opportunity to re-establish the global economy. Today, the world economy is becoming integrated as more and more state boundaries are losing their significance as a result of the expansion of trade and material exchange. Economic globalization will have profound impacts on the international environment. The promotion of international trade directly signifies the spread of economic globalization. One gets an instant sense of connectedness with the globe when one living in US sees Chinese tag on the T-shirt, Pakistani tag on the football, and South Korean sticker on the car standing in the porch. But on the other side, there are many negative impacts of economic globalization on the international environment. From a general perspective of microeconomics, the world is not at an acceptable level of equilibrium, but rather is experiencing sharp fluctuation, aggressive speculation, and controlled monopoly or polygopoly. Statistics and quantitative analysis are geared for the short term and often yield wrong and unpredictable

Hitler's greatest mistake Research Paper Example | Topics and Well Written Essays - 750 words

Hitler's greatest mistake - Research Paper Example Hitler was very much overconfident about invading Russia. The troop was not provided with winter clothing or equipments. More than half of Germen troops were frozen to death. The invasion was started on three fronts, in the south towards the Ukraine, in the north towards Leningrad, and centre towards Moscow. The moves were initially considered as successful advances. Within few days the Luftwaffe achieved air supremacy. German troops started encircling Russian defenders. Nazi legions soon conquered 1200 tanks and 600 big guns. They also gained more than 150,000 prisoners. Hitler attempted to control Russia to a great extent. Their crucial aim was to gain control over Leningrad-Moscow-Volga line. Germany’s three-pronged invasion was intended for seizing production areas in Ukraine and the Donetz basin. Germany’s plans were to acquire mineral deposits, oil and grain. They attempted to capture the Black and Baltic seas. Russian citizens were encouraged to accept the ‘scorched policy’. They were instructed that if they were forced to evacuate from their place they should not leave anything behind. They should evacuate fully. Germans at the same time started feeling trouble as weather was becoming disadvantageous for them. Russian partisan groups were gaining strength as they began imposing big tolls on supply convoys. Germans gained control over Riga, Smolensk and Kiev. They invaded Stalingrad to acquire the oilfields of Cacasus in August 1942.

Civil and Criminal Actions Essay Example for Free

Civil and Criminal Actions Essay Civil and criminal actions involve important aspects of the justice system, but the way in which each action is dealt with is different. In the early phases of the development of the laws, civil and criminal actions were dealt with in the same manner. Over time, law makers have developed differences in these two actions. The differences between them can be made by who prosecutes the cases, the details of the cases, and the outcomes sought in the cases. Civil actions involve differences between people where a person feels that another person’s actions caused him harm. According to Simmons (2008), most of the tort (civil) law is governed by a negligence standard. The object of civil actions is to address the harmful actions committed against a plaintiff by enforcing compensation from the defendant. The goal of civil actions is for the defendant to compensate and pay damages the plaintiff feels was incurred on him. Civil law cases can be brought before the state courts or the federal courts. (Simmons, 2008) In civil actions, the plaintiff usually files the case with the court. The attorneys for both parties will present their arguments to the court as to why they believe that the plaintiff or defendant should win in the case. The burden of proof comes from the plaintiff and the defendant must be able to disprove the evidence by the plaintiff. In civil cases, a vote of only 9 of 12 jurors is needed for a defendant to be found guilty. If the defendant is found guilty, the judge then determines the amount of damage or punitive damage cost that the defendant must pay to the plaintiff. (Simmons, 2008) Criminal actions do not require harm as a prerequisite. Criminal actions involve the breaking of laws and criminal offenses. The object of criminal actions is to address the crime that was committed by the defendant. The goal of criminal actions is to determine the guilt or innocence of the defendant and to punish him if he is found guilty of the crime. Criminal cases can be brought before local, state, or federal courts. (Criminal Cases, 2013) In criminal cases, the government brings charges against the defendant. The defendant who is charged with the crime is given a formal charge called and indictment or a charge called an information. The charges are usually presented at the arraignment. A preliminary hearing is then held with the judge to determine if there is enough evidence to prosecute the defendant. After the preliminary hearing, a defendant who has been charged with a felony may go before a grand jury. The grand jury determines if the defendant should be charged with the crime. The jury trial then proceeds where a prosecutor or United States attorney will prosecute the case and the defendant will have an attorney to represent him. (Criminal Cases, 2013) In criminal cases, the burden of proof lies with the prosecutor. The prosecutor must prove that the defendant is guilty beyond a reasonable doubt. After all arguments are presented to the jury, the jury will deliberate and determine if the defendant is guilty or innocent. A unanimous verdict is required in criminal cases for the verdict from the jury. If the defendant is found to be innocent, then he is released. If the defendant is found to be guilty, the judge will set a date for a sentencing. Sentencing in criminal cases is jail time and/or fines. (Criminal Cases, 2013) An example of a case that involves criminal actions and civil actions is if Brian intentionally hits Robert with his car. Brian and Robert have an argument because Robert is having an affair with Brian’s wife. Brian then gets into his car and hits Robert with the car. Robert is taken to the hospital with injuries and dies. Brian committed a crime or actus reus. Brian’s actions also included mens rea. Brian had a specific intent of causing harm to Robert and he purposely hit Robert with his car. (Lippman, 2007) According to Georgia law, Brian can be charged with murder in this case. The classification of the murder would be a felony. A felony is described as a crime that carries a punishment of imprisonment of more than one year. Brian will be charged with first degree murder in criminal court. First degree murder is when a person deliberately kills another person. Brian’s crime is mala in se meaning that the crime was dangerous for human life. Brian’s crime resulted in the death of Robert. (Georgia Code, 2013) After Brian is tried on criminal charges in the murder of Robert, Robert’s family can bring a civil case against Brian because of the harm that he did to Robert. Brian is a wealthy doctor so Robert’s family can sue for compensation to be paid to them for Robert’s death. The civil case can be filed and handled in federal court.

Education Reinforces the Race Disparity in Adventures of Huckleberry Fi

â€Å"Education is a dependent, inter-acting unit of the whole culture. Indeed, it lies at the heart of the culture, and necessarily reflects the contending values which there prevail,† writes Doxey A. Wilkerson, the associate professor of education at the Yeshiva University of New York, in the foreword for Carter Woodson’s The Education of the Negro Prior to 1861. Education, as posited by Wilkerson, represents a cultural construct, liable to change as people change, rather than a historical absolute, constant over time. The community determines the value, and the accessibility of this institution of knowledge. The communities created in Mark Twain’s Adventures of Huckleberry Finn and Langston Hughes’ Not Without Laughter also establish the importance of education. Huckleberry Finn, the white male adolescent protagonist of Adventures of Huckleberry Finn, and Sandy Rogers, the black male adolescent protagonist of Not Without Laughter, both question the necessity of formal education. However, in the end, Huck, advantaged because he is a white male, successfully abandons, unequivocally, all constraints of society, including education, while Sandy turns to formal education, attempting to use it as an equalizer against racial discrimination. The novels, Adventures of Huckleberry Finn and Not Without Laughter, reinforce the racial disparity between whites and blacks by creating communities that undermine the value of education, and determine each race’s ability to succeed without formal education. In each of the novels, the communities established by Twain and Hughes, define the characteristics prevalent in their societies. Huck Finn’s river community, for example, encompasses the aristocracy, the poor whites, the pseudo-intellectuals, an... ... and accessibility of this institution of knowledge through their status as prescribers and models for their society. The black race, on the other hand, requires extensive formal education to succeed in a world ruled by the white race. Huck Finn and Sandy Rogers embody the aspirations and beliefs of the race they identify with and compound the racial tensions through their experiences. Works Cited Hughes, Langston.

The Roman Empire Essay -- History Rome Historical Essays

The Roman Empire In 27 BC, Augustus became the first emperor of Rome, thus creating a strong leader figure, which could shape and mold the Republic system into what was best for the empire or themselves. During the reign of the emperors, the political policies for Rome would vary according to, which emperor was in power. Not only were politics shaky, but also there never was a clear-cut method of succession for the man who controlled those politics. Rome had created the position of emperor in hopes that men like Augustus would continue to lead her into prosperity, however the office of emperor struggled in attempting to find great men to lead Rome. The office never truly evolved into something greater than when it had been created, but rather the office varied according to the personality of the man in the position. Augustus created the office of emperor with the Augustan Principate, which was â€Å"to have no institutionalized authoritarian power, no perpetual dictatorship such as Julius Caesar had had himself voted early in 44, or anything like it (Stockton, 124).† Despite his wishes the people of Rome ended up giving Augustus eternal office, and powers to control the Senate with the rights to dictate agendas and veto (Stockton, 128). The people of Rome had created a position of absolute power, the exact thing Augustus was attempting to prevent. At the time the people of Rome could not have realized what they were creating in the office of emperor, for Augustus was a great man whose leadership created a great shadow over the shoulder of any future emperor. Augustus would be followed by the Julio-Claudian dynasty, which reigned over the beginnings of Imperial Rome. The succession of Augustus demonstrated the diffi... ...ed in times of good fortunes, and expansion. While during times of instability the artistic ingenuity would stagnate. Finally at the end of the empire, the art quality would decrease as the empire was deteriorating. This deterioration in art quality would continue for decades until the Renaissance would bring back an art quality on the level of that of ancient Rome under the Antonines. The type of art being created could be used as a very good indicator of what the political scene in Rome looked like at the time. Works Cited 1.
