abstract = {The spatial and temporal context of an object influence its
perceived size. Two visual illusions illustrate this nicely:
the size adaptation effect and the Ebbinghaus illusion.
Whereas size adaptation affects size rescaling of a target
circle via a previously presented, differently sized adaptor
circle, the Ebbinghaus illusion alters perceived size by
virtue of surrounding circles. In the classical Ebbinghaus
setting, the surrounding circles are shown simultaneously
with the target. However, size underestimation persists when
the surrounding circles precede the target. Such a temporal
separation of inducer and target circles in both illusions
permits the comparison of BOLD signals elicited by two
displays that, although objectively identical, elicit
different percepts. The current study combined both
illusions in a factorial design to identify a presumed
common central mechanism involved in rescaling retinal into
perceived size. At the behavioral level, combining both
illusions did not affect perceived size further. At the
neural level, however, this combination induced functional
activation beyond that induced by either illusion
separately: An underadditive activation pattern was found
within left lingual gyrus, right supramarginal gyrus, and
right superior parietal cortex. These findings provide
direct behavioral and functional evidence for the presence
of a neural bottleneck in rescaling retinal into perceived
size, a process vital for visual perception.},
