Top three traces: Box-counting analyses applied to Rorschach Blot Five (black), Rorschach Blot Ten (red), and a computer-generated fractal boundary (blue).

<p>Bottom three traces: the derivatives of the three scaling plots (see text for details).</p

Computer-generated fractal boundaries.

<p>The black pattern has a <i>D</i> value of 1.26 that closely matches that of Rorschach Blot Five, while the grey pattern has a much higher <i>D</i> value of 1.77. The black and white squares indicate the smallest and largest box sizes used in the fractal analysis of these boundaries.</p

The standardized number of reported percepts, <i>n</i>, induced by the computer-generated fractal patterns plotted as a function of their <i>D</i> value.

<p>One set of computer-generated images is illustrated above the graph. The dotted lines represent the boundaries of 95% confidence intervals. The inset tabulates the <i>D</i> values of the images along with the corresponding average number of reported perceived shapes.</p
