Measurement Techniques in Reaction Time Tests

The video tutorial demonstrates a series of reaction time tests using different sensory cues: visual, auditory, and tactile. Participants first test their reaction time by catching a ruler dropped between their fingers, recording the distance it falls. They then repeat the test with their eyes closed, relying on auditory cues, and finally with tactile cues. The tutorial emphasizes identifying outliers and ensuring consistent results, with a focus on measurement and data recording.

What is the initial setup for the visual reaction time test?

• Sitting with legs crossed

• Arm raised above the head

• Standing with eyes closed

• Arm flat on the table with fingers like a C

What was the first recorded measurement in the visual test?

• Nine centimeters

• Twenty-six centimeters

• Eighteen centimeters

• Six centimeters

Why was the number 26 considered an outlier in the visual test?

• It was the first attempt

• It was the highest number recorded

• It was measured in inches

• It was significantly different from other numbers

What change was made to the test when using auditory cues?

• Closing eyes during the test

• Standing up during the test

• Switching to a yardstick

• Using a shorter ruler

What was the first recorded measurement in the auditory test?

• 16 inches

• 10 inches

• 15 inches

• 11 inches

What was the method used to test reaction time with tactile cues?

• Touching the head

• Touching the hand

• Touching the shoulder

• Touching the foot

What was the first recorded measurement in the tactile test?

• 17 and a half

• 10 and a half

• 7 and a half

• 15

Which measurement was considered an outlier in the tactile test?

• 7 and a half

• 10 and a half

• 15

• 17 and a half

What was the final decision regarding the 17 and a half measurement?

• It was considered a mistake

• It was changed to 15

• It was kept as accurate

• It was erased

What was the purpose of repeating the tests?

• To use different measurement units

• To practice the method

• To ensure accuracy and consistency

• To increase the number of data points
