Investigating Reaction Time - PRACTICAL Flashcards
Homeostasis and Response (13 cards)
What is Reaction Time?
The time it takes to respond to a stimulus, often less than a second.
What factors can affect Reaction Time?
Factors such as age, gender, or drugs.
How can you measure Reaction Time using a ruler?
1) Sit with arm resting on the edge of a table. 2) Hold a ruler vertically. 3) Let go without warning. 4) Catch the ruler as quickly as possible. 5) Measure the distance where it’s caught.
In the ruler test, what does a higher number indicate?
A slower reaction time.
What should be done after the initial ruler test?
Drink a caffeinated beverage and repeat the test after ten minutes.
What is important to control for a fair test?
Variables such as the same person catching the ruler, using the same hand, and consistent dropping height.
What should be avoided after the experiment regarding caffeine?
Avoid drinking any more caffeine for the rest of the day.
How can Reaction Time be measured using a computer?
By clicking the mouse or pressing a key as soon as a stimulus appears on the screen.
What advantage do computers have in measuring Reaction Time?
They provide more precise measurements by eliminating human error.
What unit of time can computers record for Reaction Time?
Milliseconds.
What issue can the ruler test introduce that computers avoid?
The possibility of the person predicting when to respond.
