backColor
element objects
Fills the experiment window background with a color. You can use a backColor element if you want to change the background color for just part of a trial (when the backColor element is running). Note in the more common case that you want to set background color for whole trials or the whole experiment, just use trial object properties backColor or preTrialBackColor and/or experiment object property backColor instead.
▸ Object ends on its own?
"Ends on its own" means ends automatically at that point. If an element can end on its own, you don't need to set end conditions for it in property end (unless you want it to maybe end earlier).
No—runs until any condition you set in property end.

PsychBench uses record properties to record information during experiments. You can't set record properties but you can see them in experiment results using input property report.
