The Effect of Distractions on Reaction Time Purpose: The purpose of this laboratory is to calculate your reaction times and design a procedure to evaluate the effect of reasonable distraction on reaction times. Introduction: Distractions are a part of everyday life‚ but they can become fatal while driving a car. A distraction can be defined as a something that renders a person incapable of behaving or reacting in a normal matter. Such distractions include the use of a cell phone

Effect Of A Sport Drink On Reaction Time Abstract Doing heavy sport such as run marathon or exercise in the gym can produce much sweat. Produce too much sweat could have a significant loss of fluid and electrolytes in the body such as potassium and calcium. This can cause symptoms from fatigue and reduction in exercise performance to more serious conditions such as heat exhaustion or heat stroke (Leong‚ 2007). Drinking water after exercise helps to restore water balance in the body. Drinking

that occurs in everyone’s life. When we are born there will be a time when we are no longer young as we used to be before‚ but in fact we will start to age as the years go by. This can affect how we react to certain things and how quickly we respond. People who are older have nerve impulses that react more slowly and will have a slower reaction time than people who are younger. I think that as we grow older our reaction time does decrease.

was made. Results Reaction time to a second word or non-word is influenced by the previous word or non-word. The null hypothesis stated that all pairs would have the same mean reaction time‚ regardless of whether the first string was a word or non-word. The alternative hypothesis stated that the mean reaction time for word-non-word pairs would be slower than non-word-word pairs‚ which would be equal to the mean reaction time for non-word-non-word pairs.

Introduction Energy drinks are promoted as enhancing behavioural outcomes by reversing fatigue effects and consequently increasing alertness and endurance (Heckman‚ Sherry‚ & de Mejia‚ 2010). Ingredients may include caffeine‚ taurine‚ glucuronolactone‚ sugars‚ and other B vitamins and herbal extracts. Despite the range of constituents‚ researchers generally claim caffeine as the core ingredient responsible for the stimulatory effects of energy drinks (Reissig‚ Strain‚ & Griffiths‚ 2009)

Abstract: This project looks at how the temperature of an experiment can affect its reaction time. The purpose of this experiment is to determine if dissolving reactions are affected by waters temperature. I believe that if the H2O temperature increases‚ then the Alka-Seltzer tablet will dissolve faster because the hot water molecules will move faster colliding with the tablet particles. Water will be the independent variable due to the fact is will always stay in its same form throughout the

Investigating the effect of discomfort on reaction time Purpose and method The purpose of this investigation was to investigate the effect of discomfort on reaction time in humans‚ measured by dropping a ruler into a subject’s hand. Discomfort was caused by a bowl of ice. Background information Information is carried from the sensory receptors to the central nervous system and back the to effectors by means of nerves. When a number of different processes are involved (a situation informally

Measuring Human Reaction Time Name: Prerna Mohan Date: November 3‚ 2017 Team members: Allison Fitzgerald‚ Isabella Federico 1. Objectives The objective of this lab is to measure each individual’s reaction time using a ruler. 2. Method and Equation: We will apply free fall kinematics to find our own reaction time. An object in free fall is an object in motion where gravity is the sole force acting upon it. If we drop an object from a certain distance‚ the object will experience constant

observing our individual‚ we observed that that the Jendrassik maneuver increased reaction time. We believe this is so because it acts as a distraction due to the individual concentrating on the maneuver. This tells us that even though simple reflexes don’t directly involve the brain‚ the brain does still have influence on simple reflexes. Reflexes can be an indication of nervous system health. When the reflexes are not acting properly or are absent‚ it can tell a physician if there may be a problem
