Experiment to Investigate Factors Affecting Human Reaction Time

The video tutorial discusses an experiment to investigate factors affecting human reaction time. It outlines the hypothesis that reaction time improves with practice and describes the experimental setup, where a subject catches a falling ruler. The reaction time is calculated using a specific formula, and results show that reaction time decreases with practice but eventually stabilizes. The video emphasizes the importance of fair testing and suggests methods to ensure it, such as conducting tests in isolation and at consistent times. An alternative method using a computer program is also proposed for measuring reaction time.

What is the main hypothesis being tested in the reaction time experiment?

• Reaction time decreases with age.

• Reaction time improves with practice.

• Reaction time is unaffected by distractions.

• Reaction time is faster in the morning.

How is reaction time calculated in the experiment?

• By using a stopwatch to time the catch.

• By taking the square root of the distance fallen divided by 500.

• By dividing the distance fallen by the ruler by 100.

• By measuring the time taken to catch the ruler.

What is one method mentioned to ensure fair testing in the experiment?

• Conducting tests in a noisy environment.

• Varying the rest periods between tests.

• Performing tests at different times of the day.

• Carrying out tests in isolation to avoid distractions.

What was the stimulus in the ruler drop experiment?

• The smell of the ruler.

• The sound of the ruler hitting the table.

• The sight of the ruler being dropped.

• The feel of the ruler in the hand.

What is an alternative method suggested for measuring reaction time?

• Using a stopwatch to time the reaction.

• Using a pendulum to measure reaction time.

• Using a computer program with a visual stimulus.

• Using a metronome to keep time.
