“Are the visual characteristics of fractals responsible for the long-term appeal of Pollock’s work?”
The team developed a chaotic pendulum-based paint dribbler called ‘The Pollockizer’ to generate fractal and non-fractal poured paintings. The quantitative ElectroencEphaloGraphic brain activity (qEEG) of experimental subjects who viewed the highly fractal (and less fractal) paintings was continuously monitored and recorded using a digital qEEG recorder.
“The results […] indicate that fractal images quantified by D = 1.3 induce the largest changes in subjects’ qEEG response (Hagerhall et al., 2008). This supports the proposal emerging from perception studies that these patterns are visually unique. These fractals generated the maximal alpha response in the frontal region, consistent with the hypothesis that they are most relaxing. They, at the same time, generated the highest beta response in the parietal region, indicating that this pattern was conversely generating most activation in the processing of the pattern’s spatial properties. This points to a very interesting interplay between these brain areas for mid-D fractals, which requires further investigation.”
