Abstract: | The repetition blindness (RB) effect demonstrates that people often fail to detect the second presentation of an identical
object (e.g., Kanwisher, 1987). Grouping of identical items is a well-documented perceptual phenomenon, and this grouping generally facilitates perception.
These two effects pose a puzzle: RB impairs perception, while perceptual grouping improves it. Here, we combined these two
effects and studied how they interact. In a series of three experiments, we presented repeated items in a simultaneous string,
while manipulating the organization of the repeated items in groups within a string. We observed an interaction between RB
and grouping that we summarize with a rule that we call “the survival of the grouped”: In essence, the ability to group repeated
elements protects them from RB. These findings are discussed within the framework of the object file theory. |
