Can you help with explaining me what I could do wrong in the following situation:
I have a mouse click component. It ends the routine after I click to valid stimuli.
For the first trial only mouse click words immediately with the first left button press.
However afterwards. when I press mouse button to the valid image, nothing happens. I need to press another one to finally make a response. The same happens in the begining of each routine: firstly “free” mouse click and only after I am able to actually respond.
What the problem can be connected with?
