A reaction time measure experiment summary

Class Matching Visual Search For all operations except simple reaction, an initial visual stimulus is presented showing a code a letter, digit, or word which the user perceives and stores in short-term memory. Following a random delay of 2 to 5 seconds, a second stimulus appears whereupon the user performs a cognitive operation and then presses a key as quickly as possible according to the criterion of the operation. Here, the emphasis is visual search rather than choice reaction. All the operations implemented in this software are elaborated in detail in this book.

A reaction time measure experiment summary

Students use Excel to check and interpret the data. Each pair of students is responsible for turning in a lab report describing the procedure they used and the results they discovered. Learning Goals This particular lab has three main goals: To introduce students to using the computer for lab write-ups and data analysis.

For students to measure reaction time. To measure the acceleration due to gravity.

A reaction time measure experiment summary

Context for Use This is a indoor lab that should take only about minutes for students to complete if they have had Excel experience in the past.

Students are to work in groups of 2 to 3. This works best for classes with students in them. Students need a meter stick and a computer. If students have not had Excel experience this lab might take a little extra time but the directions for Excel are built right into this lab.

High School Description and Teaching Materials You could introduce this lab a couple of different ways. If you and talking about free falling objects you can use reaction time to confirm the acceleration due to gravity.

I like to use it as a introduction to physics lab where students get to use the computer to analyze data and become familiar with measuring. Teaching Notes and Tips Try to assign groups so that you have at least one person in each group that has used Excel before. Assessment Each group has a Lab report to turn in at the end of each lab.

I specify what I want in the report. Things I ask for are results, possible error, method, theory and conclusion.

Factors influencing the latency of simple reaction time

Standards I B.The simple reaction time is the time it takes to react to a simple stimuli — or small change in the environment (Wikipedia contributors, ).

In this experiment, you will measure your reaction time by catching a metric ruler with your fingers. In this physics experiment, you will measure your own reaction time using nothing but a simple ruler and a little math. Your partner will drop a ruler, which you will try to catch as fast as. This is a physics lab where students test their reaction time by using the acceleration due to gravity.

The use of Excel is introduced in this lab to analyze data. In the physics lab, students investigate each other&#;s reaction time by measuring how far a ruler falls before they can catch it.

Reaction time is the time between any kind of event and the response it elicits in a system. The brain is an essential part of developing a quick reaction time. In this experiment. This experiment will permit you to measure your reaction time and to compare your time with that of other people in your class.

The simplest way to measure a short time is to use the stop watch which came with your kit of parts. Mar 26,  · Simple reaction time (SRT), the minimal time needed to respond to a stimulus, is a basic measure of processing speed. SRTs were first measured by Francis Galton in the 19th century, who reported visual SRT latencies below ms in young subjects.
