Biology 104 Reaction Times Objectives: 1. Formulate and test hypotheses regarding reaction times. Introduction: Reaction time is a measure of how quickly an organism can respond to a particular stimulus. Reaction time has been widely studied‚ as its practical implications may be of great consequence‚ e.g. a slower than normal reaction time while driving can have grave results. Many factors have been shown to affect reaction times‚ including age‚ gender‚ physical fitness‚ fatigue‚ distraction

determine the reaction time of the test participant and using the subtractive method identify the selection time and identification time of the participant. The experiments had one participant who participated in a total of 6 experiments; two experiments required a simple reaction with a single stimulus and 4 experiments that required a more complicated reaction. Keywords Subtractive method – the procedure of estimating the time it takes to perform various cognitive operations. Simple reaction – this

Abstract “Reaction Time” is the interval of time between the application of a stimulus and the detection of a response and has been thought to differ based upon the effects of modality and warning signals. In the “Reaction Time” experiment a total of 24 students from the University of Cincinnati participated in an experiment consisting of two sensory modalities‚ audition and vision‚ which were combined with two levels of warning signal status. The two levels of warning signal status were signal

Experiment 1 Simple Reaction Time Abstract Summary The Research Instructor conducted an experiment about Simple Reaction Time. The Subject hold the timer while the Experimenter gave a go signal‚ and the Subject started the timer and shared stories. The Recorder used a cell phone to track the time. The Subject was not able to see the timer‚ and also the data that was being recorded. This was performed forty-five trials. Afterwards‚ the Experimenter and the Subject switched roles and performed ten

Investigation: Reaction Time Ruler Test Date: Name: Partners Name(s): Marks: /22 (Group) + /18 (Individual) = /40 Introduction: Reaction time is the time between the application of a stimulus and the body’s response to the stimulus. Reaction time is quickest for young adults and gradually slows down with age. Reaction time can be improved with practice‚ up to a point‚ and it declines under conditions

The effects of Visual Distraction on Reaction Time Abstract Distraction has been associated with affecting human reaction time. These associations have been obtained from studies focusing on drivers in particular. Driver distraction is very common nowadays and it is associated with many car crashes (Governors Highway Safety Association‚ 2011). Distraction can take forms in visual‚ cognitive‚ auditory and manual handling of the vehicle. In this study the aim was to test the effects of visual

The first reaction time test is the reaction ruler. This test shows the speed of the occipital lobe and the motor cortex of the brain. The faster the reflex the faster the afferent and efferent pathway is. Subjects 1‚ 3 and 5 experienced reaction times that were under the average of 195.167 milliseconds. While Subjects 2‚ 4 and 6 experienced times that were over the average of the population. In general terms it could be said that subjects 1‚3 and 5 have better hand and eye coordination than subjects

Written summary The reaction time test that had taken place involved the students to sit at a laptop and press the go button on the screen with their touch pad and wait for the stimulus to appear on the screen. When this stimulus would appear the student would then have to press on their touchpad with their writing hand and the amount of time that it took for the student to react to the stimulus and press the touchpad was the reaction time that was timed. The test was taken 3 times and the average of

sleep times 6‚ 7‚ 8 hours on reaction time (seconds) in humans?” concluded that the group sleeping six hours had an average reaction time of 0.54 seconds‚ the group sleeping seven hours had an average reaction time of 0.60 seconds‚ and the group sleeping eight hours had an average reaction time of 0.45 seconds. The hypothesis was somewhat supported with the group sleeping eight hours having the highest reaction time‚ however‚ the group sleeping seven hours hours had a slower reaction time than those

Observing how long it takes a person to perform an action‚ now known as observing the reaction time‚ has even gained enough importance to the point that it has even used in some scientific investigations
