(unexecuted) key lifts affect following responses
Dear Open Sesame team,
i was trying out some stuff my participants could make wrong when i found something really strange.
In a four choice reaction time task, participants have to react to several stimuli in a row. The next stimulus always appears when one of the target keys is pressed.
When i do not lift the first key, but press the next keys...
--> everything ok. Next stimulus presented.
When i do not lift the first key, do not lift the second key...
--> with pressing the third key, the next stimulus is not presented
--> however when i then lift the first or second key, the next stimulus is presented
This is unexplainable for me, as i did not mention lifts in my script.
