Document Summary
Learning objectives: define the minimum amount of time necessary for visual feedback to impact a movement and explain how we know this. Size, shape, proximity and colour (looking for a stimulus) If the movement is about less than 150 ms you make the same amount of errors blind or not: only after 150 ms does it make a difference. Dynamic conditions: not a lot in our every day life is static, everything is constantly changing. It gets harder to process information with dynamic situations compared to static: the time you have for the visual processing becomes shorter. Stimulus vs. response: a stimulus either present or absent (the word red, response is either that the stimulus is present or not present, yes=tap your finger, no= not tap your finger. If the stimulus is present you would respond yes- this is called a hit on the stimulus. If the stimulus is not present you would want it to be no response.
