Results of Study 5 plotting fractal dimension against release years for three movie variables. Left: A scatterplot of the increase in long-range dependence, measured by the exact local Whittle estimator and of the scene-duration vectors of 24 movies from 1940 to 2010. The regression line and 95% confidence intervals are also shown. The small error bars in the left panel indicate the standard deviations in generating 1000 pseudo-random sequences with the measured Whittle value and number of scenes for the given movie. Middle: The scatterplots of the fractal-like measure of motion in each shot for the shot vector in 180 movies. Right: A decline in long-range dependence for sound amplitude in sample vectors of 48 movies. All panels show a reliable change in long-range dependence over release years. The upper horizontal green line represents the approximate fractal value of 1/f 1 (pink noise) as determined in Study 3; the lower line represents 1/f 0 (white noise)
