PsychoPy version: PsychoPy 3.2.3
Standard Standalone? (y/n): y
Hi everyone. I am currently trying to implement a task in which the subject is asked to estimate the duration of a target stimulus through the use of the space key: a first time to make the stimulus appear and a second one to “block” it, depending on the duration of the stimulus target seen just before. The problem is that for every trial I would like the timer to be reset, so that the correct time between the first use of the space key and the second (the time estimate of the target stimulus) is displayed directly in the data file. I am attaching the code. How can I do it? Thank you.
