And in this line, would it be possible to implement a response trial that begins on participants releasing a keypress? thanks again, Juliane Yes, a <trial> can accept a key release as response. To specify a release prepend a minus sign to the respective keyboard scan code. E.g. <trial mytrial> ... / validresponse = (-57) ... </trial> would accept a release of the spacebar as its response. thanks a lot, works nicely!
