“…The Bayesian and anti-Bayesian predictions are independent of the mismatch between image size and known size. In the design of the experiment, we therefore did not consider how a potential mismatch between familiar size and depicted size would influence behavior, as it has been shown to do for reaction times (in a way resembling the Stroop effect [ 40 , 41 , 42 ]). To maximize precision, we gave our participants all the time they needed to generate a response.…”

It is known that judgments about objects’ distances are influenced by familiar size: a soccer ball looks farther away than a tennis ball if their images are equally large on the retina. We here investigate whether familiar size also influences judgments about the size of images of objects that are presented side-by-side on a computer screen. Sixty-three participants indicated which of two images appeared larger on the screen in a 2-alternative forced-choice discrimination task. The objects were either two different types of balls, two different types of coins, or a ball and a grey disk. We found that the type of ball biased the comparison between their image sizes: the size of the image of the soccer ball was over-estimated by about 5% (assimilation). The bias in the comparison between the two balls was equal to the sum of the biases in the comparisons with the grey disk. The bias for the coins was smaller and in the opposite direction (contrast). The average precision of the size comparison was 3.5%, irrespective of the type of object. We conclude that knowing a depicted object’s real size can influence the perceived size of its image, but the perceived size is not always attracted towards the familiar size.

“…Consistently, familiar size gives rise to interference with physical size judgments: during a two-alternative forced-choice (2AFC) size-judgment task, subjects were faster to indicate the relative display size of an object when it was congruent with the real-world size (i.e., a car displayed larger than an apple, rather than vice versa) [ 7 ]. Furthermore, when depth information was restricted, objects depicted in sizes closer to their real-world size were detected significantly faster than those that were more different from their familiar size [ 8 ]. These findings illustrate that retinal and familiar object sizes interfere at common processing levels.…”

Prior knowledge alters perception already on early levels of processing. For instance, judging the display size of an object is affected by its familiar size. Using functional magnetic resonance imaging, we investigated the neural processes involved in resolving ambiguities between familiar object size and physical object size in 33 healthy human subjects. The familiar size was either small or large, and the object was displayed as either small or large. Thus, the size of the displayed object was either congruent or incongruent with its internally stored canonical size representation. Subjects were asked to indicate where the stimuli appeared on the screen as quickly and accurately as possible, thereby ensuring that differential activations cannot be ascribed to explicit object size judgments. Incongruent (relative to congruent) object displays were associated with enhanced activation of the right intraparietal sulcus (IPS). These data are consistent with but extend previous patient studies, which found the right parietal cortex involved in matching visual objects presented atypically to prototypical object representations, suggesting that the right IPS supports view normalization of objects. In a second experiment, using a parametric design, a region-of-interest analysis supported this notion by showing that increases in size mismatch between the displayed size of an object and its familiar viewing size were associated with an increased right IPS activation. We conclude that the right IPS performs view normalization of mismatched information about the internally stored prototypical size and the current viewing size of an object.
