Performance across the different expectation conditions, collapsed across spatial frequency, in the <i>Perception Of Meaning</i> task.

<p>Data plotted separately for individuals scoring below and above the median on the <i>UnEx</i> subscale of the <i>O-LIFE</i> (<i>N</i> = 94, error bars represent ±95% confidence intervals). The reference lines in panels a and b represent chance performance (yes-no task), whereas the reference line at β = 1 in panel d represents the point of no response bias for an unbiased responder. A β value less than 1 indicates a bias toward saying a face was present in a noise-only stimulus.
