| show | letters flash on screen one at a time every 100 ms, some letters are in red, participants asked to focus on, asked what letters they recall, if lay between each letter is 200 ms, effectively blind, when come right after each other, can't help but notice
🗑
|
||||
| show | at 500 ms it improves to the 100 ms initial reaction, spike of attention fades after 100 ms, this task measures temporal attention
🗑
