Onset stimulus can capture attention and then transfer into visual short-term memory. It remains unknown whether two sudden onsets also capture attention and are stored in vSTM. We modified Belopolsky, Kramer, and Godijn’s (2008) visual search paradigm to test this issue. Experiment 1 using one onset and replicated Belopolsky et al’s results. Two onsets in Experiment 2 were found to capture attention; however, recognition performance for the onsets was only at chance level, showing poor memory. Experiment 3 used a retro-cue to test whether only one of these two onsets can be stored in vSTM. Experiment 4 tested whehter this poor recognition was caused by interference from meory probe. This study has important insights on how attention interacts with memory.
