The first five rows of data indicate the proportion of times participants perceived an unbound test array as being larger than a fixed unbound reference array. The second five rows indicate the proportion of times participants perceived a binding ring array as being larger than a fixed unbound reference array. Each proportion was calculated from 20 trials.

For subjects 1-10, values indicate the average difference in a radius at which participants made a reversal choice in the staircase for each of the five conditions tested labelled: BR Shift Xº. Each condition was tested 4 times and 5 reversals were recorded resulted in 20 total reversals. The 1st reversal of each trial was excluded from analysis. The mean for each subject(shown) was automatically computed by the stimulus presentation software: Adjustable_BR_Staircase.m on the basis of the remaining 4 reversals per trial.

For the control conditions, the rows of data indicate the proportion of times participants perceived a unbound test array as being larger than a fixed unbound reference array. For the binding ring conditions, the rows of indicate the proportion of times participants perceived a binding ring array as being larger than a fixed unbound reference array. In the high spatial frequency (HSF condition), both arrays were high-pass filtered. In the low spatial frequency (LSF) condition, both arrays were low-passed filtered. Each proportion was calculated from 20 trials.

In experiment 4a the first five rows of data indicate the proportion of times participants perceived an unbound test array as being larger than a fixed unbound reference array. The second five rows of indicate the proportion of times participants perceived an array with a line connecting the local elements as being larger than a fixed unbound reference array. Each proportion was calculated from 20 trials.
In experiment 4b the first five rows of data indicate the proportion of times participants perceived an unbound test array as being larger than a fixed unbound reference array. The second five rows of indicate the proportion of times participants perceived an array with a line intersecting only the interiors of the elements as being larger than a fixed unbound reference array. Each proportion was calculated from 20 trials.
