We present an experiment on the immediate and lasting effects of reminder nudges in a complex environment. In study, 1,542 subjects face setting where, within brief time frame, they have to pay attention perform multiple actions computer game. The investigates i) effect reminders reminded their spillovers nonreminded actions; ii) between when number is increased; iii) intertemporal from having been exposed after are withdrawn. Our findings reveal, first, that positive overall performed. It results direct dominating negative actions. These notable our setting, where could potentially by freezing or indirectly prompting similar ones. Second, we observe scalable. Increasing leads take more overall, albeit with diminishing returns pronounced spillover effects. Third, withdrawn, diminishes, while persist, thus rendering ineffective increasing
