abstract = {The current study determined in healthy subjects (n = 16)
whether size adaptation occurs at early, i.e., preattentive,
levels of processing or whether higher cognitive processes
such as attention can modulate the illusion. To investigate
this issue, bottom-up stimulation was kept constant across
conditions by using a single adaptation display containing
both small and large adapter stimuli. Subjects' attention
was directed to either the large or small adapter stimulus
by means of a luminance detection task. When attention was
directed toward the small as compared to the large adapter,
the perceived size of the subsequent target was
significantly increased. Data suggest that different size
adaptation effects can be induced by one and the same
stimulus depending on the current allocation of attention.
This indicates that size adaptation is subject to
attentional modulation. These findings are in line with
previous research showing that transient as well as
sustained attention modulates visual features, such as
contrast sensitivity and spatial frequency, and influences
adaptation in other contexts, such as motion adaptation
(Alais $\&$ Blake, 1999; Lankheet $\&$ Verstraten, 1995).
Based on a recently suggested model (Pooresmaeili, Arrighi,
Biagi, $\&$ Morrone, 2013), according to which perceptual
adaptation is based on local excitation and inhibition in
V1, we conclude that guiding attention can boost these local
processes in one or the other direction by increasing the
weight of the attended adapter. In sum, perceptual
adaptation, although reflected in changes of neural activity
at early levels (as shown in the aforementioned study), is
nevertheless subject to higher-order modulation.},
