NEURODESIGN® · MATERIAL CLASS · WOOD AND PLANT STRUCTURE
Engineered wood and plywood
Laminated veneer over a stable core. Visually a wood surface, compositionally a glue-bearing assembly.
Decisive attributes
The attributes that most determine how this class behaves and how it is experienced. No values are shown, because a value belongs to a product and not to a class. Two products of the same material can differ from each other by more than the material differs from its neighbours.
Typical application
Flooring. Panelling. Casegoods.
Worth watching
Whether evidence collected on solid wood transfers to a 0.6 mm veneer over an adhesive core is an open question and is treated as one here.
Evidence
3 records in the research corpus reach this class. Each carries its own evidence strength and translation distance, shown below. Read both: a finding can be strong and still be several inferential steps from a specification.
These records study wood as a class. None of them distinguishes hardwood from softwood, or solid timber from a veneer over an adhesive core, and most do not state what finish was on the material tested. The evidence is located one level above this entry, and it is shown here on that understanding.

Psychophysiological responses to indoor wood use: A systematic literature review of indicators, methods, and research trends
Authors per journal record. Building and Environment
Visual wood exposure is the most studied modality, with heart rate and prefrontal measures common; the field needs longer exposures and more diverse samples.

Effect of Wood Indoor Environments on Human Psychophysiological Responses and Evaluation Indicators: A Review
Authors per journal record. Journal of the Korean Wood Science and Technology
Across 24 selected experiments, wood exposure generally tended toward more favorable psychological and physiological responses.
ND-0083 · 2019 · Experimental study
Physiological effects of visual stimulation with full-scale wall images composed of vertically and horizontally arranged wooden elements
Nakamura, Ikei & Miyazaki. Journal of Wood Science
Wooden-wall images reduced prefrontal oxyhemoglobin relative to a gray control and improved several subjective mood impressions; vertical and horizontal arrangements differed.
Outcomes it could bear on
Outcomes whose material levers overlap this class. This is a structural relationship in the ontology, not a finding: it says the property is relevant to the outcome, not that this material produces it.
