Investigations of human EEG response to viewing fractal patterns

What the study found

EEG responses varied with fractal dimension; a mid-range fractal dimension produced distinctive frontal alpha and parietal beta patterns.

Limitations

Simple silhouette stimuli; neural meaning of band changes is not a direct wellbeing measure; small study.

Neurodesign interpretation

Fractals are valuable because complexity can be quantified. That makes a normally vague design idea, visual richness, experimentally manipulable.

Possible design implications

Use fractal complexity as a testable pattern variable, not as proof that every naturalistic pattern reduces stress.

Why it stays in the corpus

Retain as a primary physiological fractal paper.
