Visual and tactile properties of materials can influence human emotional and cognitive functioning. Existing studies indicate that exposure to wood may lead to more favourable outcomes than contact with other common materials, but evidence is limited. We measured affective states and cognitive performance in 16 participants before and after each spent 15 min at 10 desks with differing top surfaces. Desk surfaces were made of untreated, oiled, or lacquered spruce or oak solid wood, laminated or oak-veneered particleboard, glass, and mineral-filled thermoplastic composite. The results indicate that cognitive performance and affective states of participants did not differ between the desk surfaces. It appears that exposure to a relatively small wooden surface does not significantly influence affective and cognitive outcomes. Incorporating larger amounts of wood coverage and a more demanding cognitive task would probably increase the chances of capturing the potential effects of wood exposure on human affective states and cognitive performance.

课桌材料对情绪状态和认知能力的影响

材料的视觉和触觉特性会影响人类的情感和认知功能。现有研究表明，与接触其他常见材料相比，接触木材可能会带来更有利的结果，但证据有限。我们分别测量了16名参与者在10个桌子上有不同顶面的15分钟前后的情感状态和认知表现。桌子表面由未经处理，上油或上漆的云杉或橡木实木，层压或橡木贴面的刨花板，玻璃和填充矿物的热塑性复合材料制成。结果表明，参与者的认知能力和情感状态在桌子表面之间没有差异。似乎暴露在相对较小的木质表面上不会显着影响情感和认知结果。
