HBS 2.2.3. Reaction Time Experimental Design I. Identify a Problem or Question: Can the reaction of an individual be affected by other external factors? II. Introduction: Reaction time refers to the amount of time it takes for a person to process and react to a stimulus. It is important in everyday activities‚ such as driving‚ and sports‚ but not much experiment is conducted to research on this matter. Reaction time with its practical implication can leads to great consequences‚e.g. d

As mentioned‚ our results suggest that the distraction times vary greatly on different individual factors. However‚ with the overall averages at 237 for no distractions compared to 315 for distractions‚ our team’s hypothesis still holds true that distractions greatly affect reaction time. Our experiment demonstrated to us that there are two factors intertwined in influencing reaction time: the distraction itself and the individual’s ability to react while distracted. For example‚ a cellphone app

A. Introduction Title: The effect of reading Shakespeare on reaction time Research Question: Does reading a passage of Shakespeare decrease a person’s reaction time while completing a puzzle? One day in class‚ I was reading an interesting article about how people who read and are exposed to Shakespeare and Wordsworth and other renowned writers have better brain activity‚ attention spans‚ and can have more moments of beneficial self-reflection. In the article‚ scientists and psychologists at Liverpool

How do sports drinks affect reaction time? My goal was to test different drinks that are advertised to help you have a better athletic performance‚ and to find out which one worked best. Procedure: 1. I measured each test subject’s reaction time prior to exercise for comparative measures. 2. I divided each 1200ml portions of Gatorade‚ Powerade‚ and Water into 300ml portions respectively. 3. I had each test subject take one of the drinks and go on a 30min run. I then‚ instructed the subjects

Nicotine and Reaction Time Introduction: Nicotine is a drug‚ nerve poison‚ sedative and also a stimulant. It is said to have stimulating and relaxing effects‚ but it depends on the dosage of nicotine. As it was mentioned above‚ Nicotine is both a stimulant and a sedative; this means that straight after you have ingested nicotine‚ it gives you an adrenaline rush and also helps you to relax afterwards i.e. crash. This means that if I conduct my experiment straight after the smokers have ingested nicotine

Changing the Rate of Reaction PART 1: PARTICLE SIZE Question: How does changing the particle size of marble (CaCO3) affect the rate of reaction when it is added to hydrochloric acid (HCl)? Hypothesis: If I change the particle size of marble to test how to change the rate of a chemical reaction‚ than the chemical reaction with the smallest marble particles will produce CO2 the quickest because the larger the surface area‚ the more place the hydrochloric acid will have to collide with the marble

experiment: In this experiment I will investigate the relationship between the concentration of the hydrochloric acid and the rate of a reaction. To find this out I will react different concentration of hydrochloric acid and magnesium‚ from there I will monitor the gas (hydrogen) produced and analyse the results. Prediction: I predict the higher the molarity of the hydrochloric acid the faster the rate of reaction therefore the quicker the gas will be produced in the specific time interval. Overview
