Design of a Psychological Experiment Psyc 100 (0110-0129) Fall‚ 1996 Dr. Sternheim Report #1 (10 points) Problem: Suppose you are a psychologist who is interested in the effects of caffeine on the eye-hand coordination of students enrolled at UMCP. Design an experiment to test the hypothesis that caffeine enhances a student’s ability to hit a baseball. Describe your experiment by answering the following questions: 1) What are the independent and dependent variables? The independent variable

Catalase in Various Concentrations of Hydrogen Peroxide QUESTION: How long does the catalase take to float to the top of a cup filled with different amounts of hydrogen peroxide concentration? PREDICTION: A prediction that can be made for this experiment is that the higher the concentration‚ the faster time it takes the catalase to react with the solution. As the concentration increases from 1% to 100%‚ the average reaction rate of the catalase will decrease‚ as the catalase will speed up the reaction

* Bibliography............................................................................................... Aim: The aim of the experiment that was carried out was to see‚ at what temperature and in which standard solution‚ does the amount of dye left in the boiling tube had the highest percentage transmission. Beetroot was used for the experiment because it was easier to see the dye after the practical was completed. Putting beetroot cylinders into different boiling tubes‚ which contained

interallelic interactions (independent assortment vs epistasis) govern the inheritance of seed colour. ii) Understand the scientific process involved in studying character inheritance. For example‚ formulation of null and alternate hypotheses; design experiments to test the hypotheses; statistical analysis of results; draw logical conclusions iii) Interpretation and presentation of results. For example‚ provide genetic and biochemical explanations to explain your results. Important: Students are required

The aim of the experiment was to examine the effects of consuming lactate before and during a prolonged exercise. The data shows that the consumption of the lactate actually did work and the performance of the subject was better than the previous three experiments of dieting. This was due to the lactate that was consumed in the CytoMax. Azevedo‚ Tietz‚ Two-Feathers‚ Paull‚ and Chapman (2007) state that CytoMax contains polylactate which speeds up the delivery of substrates and is thought to help

Describe the physiological approach to the study of the mind. Explain how Donders experiment can be repeated in a modern laboratory using the physiological approach to the study of the mind Donder’s work attempts to describe the processes going on in the mind‚ by analyzing cognitive activity into separate stages. Until Donder’s work‚ many scientists had assumed that the mental operations involved in responding to a stimulus occurred instantaneously. Donder was particularly interested in "timing

Dwight Howard‚ who is already playing basketball‚ asks him what’s in the bag. Dwight tells him he has a big mac and fries. Dwight asks LeBron to bet his lunch and he agrees to have a slam dunk competition. Dwight won but suddenly Larry Bird appears and takes the McDonald’s bag.

Bouncy Ball Experiment Aim: The aim of this experiment is to investigate the efficiency of a bouncing ball‚ and the factors which affect its efficiency. Prediction I predict that the higher I drop the ball from the higher it will rebound up‚ because it will have more gravitational potential energy the higher dropped from. As it is dropped the ball will have kinetic energy‚ and then when it hits the ground changes to heat and sound energy‚ and kinetic as it rebounds back up. The higher up

In this experiment‚ one of the big is osmosis‚ and how it had the overall impact in this excitement a little on osmosis. Osmosis takes place when two solutions of different concentrations are separated by a semi-permeable membrane in which the solvent can pass through but not the solute. In our experiment‚ we used a sucrose solution that will be a hypotonic concentration of solute. This tells us that the solution has a lower concentration of water than does the cells. Therefore‚ due to osmosis‚ the
