  • Verbal Reaction Times Experiment

    2635 Words  | 6 Pages

    This report aimed to replicate Stroop's (1935) experiment. Using the repeated measures design and a sample of 20 students, differences in verbal reaction times on two tests were observed. The one-tailed hypothesis predicted that it would take longer to say words in the Cc, this is the conflicting condition where the colour of the word differs from the colour that the word describes. It was found that, using the t-test for related data, this hypothesis could be accepted as the obtained value

    the smallest reaction time compared to all the other. The incongruent counting task had the longest reaction time out of the other three tasks. The incongruence in the stimulus in the incongruent counting task created similar effects as the Stroop phenomenon. The hypothesis that the reaction time would be larger in the incongruent counting task was supported in this experiment, as well as the prediction that the congruent counting task will in fact have a lower reaction time than the incongruent;

    The aim of the experiment is to find out the effect of different concentrations of reactants on rate of reaction. Rates of Reaction Aim The aim of the experiment is to find out the effect of different concentrations of reactants on rate of reaction. I will find this out by doing an experiment. The reaction that will be used is: Sodium Thiosulphate + Hydrochloric Acid Na2S2O3 + 2HCl Equipment The equipment I will use to do this experiment is: · Goggles · Test tubes · Beakers

  • Disappearing Cross Investigation

    1179 Words  | 3 Pages

    Using the idea of the particle theory, the more dilute a solution is, the more time it will take for the particles to react. This is due to the fact that the particles have less energy reducing the collisions and the speed of which they collide, therefore taking longer to react. I predict that the more water I add to the solution the longer it will take the cross to not be visible. Variables: In this experiment I will only need to decrease the concentration of the Thiosulphate and I will

  • The Effects of Increasing the Concentration of Sodium Thiosulphate When Reacting with Hydrochloric Acid

    reaction was fast or slow in a high concentration and a low concentration. I will do 8 experiments repeated 3 times each to get better results and be more accurate to the real answer. In the experiments I will lower the concentration and add 10cm3 added of H2O every time I lower the concentration of sodium thiosulphate by 10cm3. I will observe the 8 experiments repeated 3 times each. Each experiment I will have different amounts of concentration of sodium thiosulphate starting with 90cm3

    cruel. Twain is right because many psychological experiments have proved this. Some humans may be kind, but the facts and research proving humanity is cruel outweigh and overshadow those people. Over the past seventy-five years many psychology

  • The Effects of Concentration on Reaction Rate with Sodium Thiosulphate

    1224 Words  | 3 Pages

    Reaction Rate with Sodium Thiosulphate ---------------------------------------------------------------------- Planning ======== In this experiment I shall be varying the volume of sodium thiosulphate, hydrochloric acid and water, and measuring the reaction rate. When I increase the amount of sodium thiosulphate with less water, I think the time for the cross to disappear would be faster than there would be with little sodium thiosulphate and more water – taking in account the amount of

  • Investigating the Effect of Temperature on the Rate of a Reaction

    648 Words  | 2 Pages

    volume of gas given off over a period of time. I have chosen to use temperature instead of concentration because I believe it will create better results and make an easier experiment. Prediction: I believe that when the temperature is increased the particles energy will increase there for creating more collisions between the magnesium and the acid. In effect increasing the speed of the reaction. Preliminary work: After doing various experiments in my preliminary work I decided to use:

  • Cognitive Psychology: The Stroop Effect

    1258 Words  | 3 Pages

    of the earliest and most famous experiments into cognitive processes. It was published by John Ridley Stroop in 1935 and is a phenomena involved in attentional processes. It demonstrates the effects of interference, processing speed (reaction time) and automatically in divided attention. Stroop created two experiments with the aim to investigate whether visual interference affects the cognitive processing speed in naming incongruently colored words. The experiments portray a psychological test of

  • Projectile Motion Lab Report

    1137 Words  | 3 Pages

    This experiment introduces kinematics, an important physics concept describing objects in motion, to explore projectile motion in two dimensions. The kinematics of motion can be expressed by certain equations, which show the relationships between velocity, acceleration, time, and displacement. Two experiments were conducted to utilize two specific equations; one by launching a ball horizontally to investigate the time of flight, and another by launching the ball at different angles to determine its

  • Rate of Reaction Between Calcium Carbonate and Hydrochloric Acid

    in the experiment is Hydrochloric Acid. I want to find out how different strengths of acid affect the speed of the rate of reaction. The variables that could affect the rate of reaction are: · Temperature · Concentration of Acid · Surface Area · Increase Pressure (this is not applicable in this experiment) · Catalyst (this is not applicable in this experiment) · Volume · Mass of Calcium Carbonate · Stirring the Solution. I will set up the experiment as shown

    considered 7 and under, while the other age groups would be considered the older age groups. The results of the experiment refuted the original hypothesis, which is: If age affects the amount of light needed to help distinguish colors, then younger ages will be able to distinguish colors in less lighting compared to older ages. Test subjects eye color was not controlled during the experiment and could have been the factor that resulted in the information collected. Pigmentation of eyes is a big factor

  • Use of Experiments in Natural Sciences and in Sociology

    862 Words  | 2 Pages

    Use of Experiments in Natural Sciences and in Sociology Experiments are particularly important in natural sciences as they are the device used to either prove or disprove a hypothesis. Sciences such as chemistry or physiology operate in what is known as closed systems, where all the variables can be controlled. This means therefore that such experiments can be carried out, and effectively. Whereas it may be difficult in physical sciences to control the variables, and in sociology to recreate

  • The Social Psychology of Obedience

    787 Words  | 2 Pages

    In 1963 Stanley Milgram, a Yale psychologist, created an experiment examining obedience. This experiment has been questioned by many psychology professionals. One psychologist Diana Baumrind transcribes her feelings in the “Review of Stanley Milgram’s Experiments on Obedience.” Baumrind, when writing the review, was employed at the Institute of Human Development, University of California, Berkeley. In her review Baumrind denounces Milgram for his treatment of his subjects, potentially harming their

  • What Is Overconfidence Bias?

    1703 Words  | 4 Pages

    Review of Overconfidence Bias Human beings are models of overconfident. Overconfidence is a person’s decision-making that relays bias to seek confirming evidence. People believe that they are better at sports than others, better eye-witnesses, and even better drivers than the average. According to Halpern (2014), a lot of people don’t improve on the way they perceive and decide on situations, due to the misconception that they are already making the right decisions. For example, imagine going on

    After time periods of every 30 seconds I measured the amount of gas in the syringe, this will continue until one of two things happened. Either the volume of the gas syringe gets past 100cm and it is necessary for the back of the gas syringe to be taken out, otherwise it could drop out and smash, or the volume of gas remains constant for 1 minute, and then that particular experiment will end. 1Molar Room temperature-27 c. 1M Room temperature-27'c.
