Making decisions often requires the integration of multiple pieces of information that may become available at different times. An extensive body of research has investigated the neural mechanisms underpinning evidence accumulation in tasks where information is continuously available, but less is known about how humans make decisions based on temporally separate samples. Here, we ran two electroencephalography (EEG) experiments using a modified version of the standard Random Dot Kinematogram (RDK). In our tasks (N = 22, N = 21), two pulses of evidence were presented separated by "gaps" of vary
