![]() However, I want all stimuli to be unchanged at the beginning of the second run, i.e., a reset of these stimuli at the end of the first run. The problem here is that stimuli that were changed during the first run keep changed at the start of the second run. Step 7: Fix Any Issues in Psychopy Builder. I’m pressing é while running my experiment online. ![]() I go look in the data file generated : é is recorded in the keys pressed. Example: I’m pressing é while running my experiment with the builder. I’ve done an experiment in builder and wanted to push it out online. Description of the problem: I’m new to PsychoPy/PsychoJS, so I’m sorry if this is a trivial problem. Step 6: Pilot the Psychopy Online Project. On the web, the experiment registers something else. URL of experiment: validtask6 PsychoPy I know that this is only pilot, because I didn’t want to use credits for an experiment that is not working. Step 5: Navigate to Experiments on Pavlovia. Step 2: Build Your Experiment in Psychopy Builder. Subjects need to repeat this trial 5 times. Step 0: Download PsychoPy On Your Computer & Create a Pavlovia and GIT Account. The second one concerns the repetition of trials. Two buttons pressed during that (100 ms) time window will change the stimulus? Would it be possible to allow for a larger temporal window, say 100 ms. But the location of target stimuli is obtained in pixel, I wonder. Because if I specify the location of my stimulus in pixels, it might display in the wrong place due to different pixel size across monitors for the online experiment. Two buttons have to be pressed in combination, and stimuli are only changed if the two buttons are pressed at more or less the same time, checked at the screen refresh rate of 60 Hz (temporal window of 16.6 ms). Hi, I’m trying to manipulate the position for each stimulus precisely on the builder for an online experiment using the units of height rather than in pixels. ![]() The first one concerns the timing of the button presses. I realise that I already took a significant amount of your time, but may you allow me two final questions? Success! Now the key types and times are stores. What makes a PsychoPy experiment Block designs and counterbalancing.
