The Effect of Stimulus Type on Reaction Time Katelin Wagoner Anderson University Abstract Previous studies on reaction time have examined the effects of different kinds of stimuli; this experiment specifically tests reaction time in response to auditory and visual stimuli. The common belief is that an auditory stimulus is faster than visual stimuli. There were 23 participants; 95% were Caucasian‚ with six males and 17 females. This experiment required participants to respond to either an

SIMPLE REACTION TIME Objective To acquaint the students in reading laboratory primers and organize data into summaries and graphs. Introduction Apparatus Required Stopwatch‚ Meter Stick. Procedure Part – I Select your laboratory partner and toss a coin to determine who will be E and S. S holds the timer with preferred time. At E’s go signal‚ S starts the timer and must talk of free associate while making an estimate of 12 second interval. E records the estimate in Table I. S should not see the face

In our experiment‚ we have decided to use all the “cases” which will test how fast a signal from our brain will be sent to our

Problem: Reaction time can be a very important thing in daily life. Reaction time is not only crucial for an athlete when playing quick sports but the average person will need to use their reaction time in daily life. When an object falls‚ catching the object or when driving‚ having a quick reaction time could be vital to the safety and wellbeing of the driver and the passengers even when it comes down to differences in seconds. In addition‚ there have been many catastrophic events in the

The four basic reflexes that babies are born with are root reflex‚ suck reflex‚ moro reflex and grasping reflex and each of them has a function in infants. • Root Reflex This reflex begins when an infant’s cheek is rubbed or the side of the mouth is touched. In response‚ the baby turns his or her head and open his or her mouth to follow and root in the direction of the stroking. Also‚ the infant begins to make sucking movements with his or her mouth. Therefore‚ this reflex plays an important role

storyline of the film Modern Times revolves around the two characters‚ a factory worker and street rogue‚ played by Charlie Chaplin and Goddard respectively‚ who fall short to take part into the modern and mechanized world. There were several themes clearly emphasized in the beginning of the film; the workers are portrayed as mere followers‚ no distinctiveness‚ merely considered as moving parts in the economic system. The two main characters were seen as being non-conformant. Time as shown in the beginning

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

travel in this time? a = (28-0m/s)/20s = 1.4 m/s/s x = 1/2at2 = ½(1.4)(20)2= 280m 2. At t = 0 a car has a speed of 30 m/s. After 6 s‚ its speed is 15 m/s. What is its average acceleration during this time interval? a = (15-30m/s)/6s = -2.5m/s/s 3. A bear spies some honey and takes off from rest‚ accelerating at a rate of 2.0 m/s2. If the honey is 10 m away‚ how fast will his snout be going at the moment of ecstasy? Hint: Solve for time to go 10m then use time to find velocity

Dominance on Neuromuscular Reaction Time Abstract Neuromuscular reaction time may be influenced by hand dominance. This study examined whether hand dominance could influence the measurements of neuromuscular response by catching a meter stick in free-fall. A total of 9 subjects were examined with respect to hand dominance. The mean of the neuromuscular reaction time of the dominant and non-dominant hand was 268 mm and 314 mm‚ respectfully. The neuromuscular reaction time of the dominant hand was

subtraction technique to time the different mental processes that the brain goes through when faced with different tasks. Donders performed experiments using reaction time tasks in 1868. His was the first attempt to analyze and measure the component processes of a simple task. 1. a simple reaction time task - e.g. you are seated in front of a panel that contains a light bulb and a response button. When the light comes on‚ you must press the button. 2. a choice reaction time task - e.g. you are
