An unexpected stimulus often remains unnoticed if attention is focused elsewhere. This inattentional blindness has been shown to be increased under conditions of high memory load. Here we show that increasing working memory load can also have the opposite effect of reducing inattentional blindness (i.e., improving stimulus detection) if stimulus…

Data indicated that when the computational demands imposed by the original task are reduced, young children can and do remember what they had thought about the contents of a tube even after its true…
