Components of error in the working memory task. (a) The distribution of responses was decomposed into a mixture of
three separate components: responses distributed with Gaussian variability around the correct (target, T) orientation
(top), responses distributed around the orientations of other, non-target (NT) items in the memory array (middle), and
random responses distributed uniformly throughout the response space (bottom). (b) Maximum likelihood estimates of
parameters of the mixture model illustrated in (a), for different array sizes and exposure durations. Gaussian variability in
target responses (black symbols) increases with array size but decreases with exposure duration. The frequencies of
