Physiological effects of visual stimulation with full-scale wall images composed of vertically and horizontally arranged wooden elements

What the study found

Wooden-wall images reduced prefrontal oxyhemoglobin relative to a gray control and improved several subjective mood impressions; vertical and horizontal arrangements differed.

Limitations

All-female young sample; image rather than real material; very short exposure; mechanism of orientation effect unknown.

Neurodesign interpretation

The intriguing part is orientation: even with the same wood rotated, responses differed. Surface organization may matter as much as material identity.

Possible design implications

Test material layout and coverage, not only material category.

Why it stays in the corpus

Retain as a specific material-pattern experiment.
