What are you trying to achieve?: a randomized fixation duration between 1s and 2s
I (a newbie) am learning Psychopy through building the original Posner Cueing Task where a fixation with a random duration between 1 to 2 seconds needs to be present right before the cue.
When building this fixation I created a new Routine with a just for the fixation itself, and a Routine including the cue, the target, and a response component is immediately after the fixation Routine.
For the fixation, I set the duration field in the Polygon component to be ‘duration(S) = random() + 1’ , and it starts at 0.0s.
However, when I analyze the excel sheet after a run to verify this randomized duration, the duration never exceeded 1.5 seconds with the longest duration of 1.38s. Since there were 50 trials, I am expecting about 25 trials to be over 1.5s, and that’s why I believe something went wrong.
Can anyone help me make a diagnosis?
