摘要

接觸自然材料會讓人產生愉悅、舒適的感覺。在過去人體接觸木材的研究中發現，人在觸摸木材後與接觸其他人造材料相比，生理上呈現心率及血壓降低、前額葉皮質活動保持平穩、副交感神經活動增加，顯示與木材接觸不僅有生理放鬆之現象，且在主觀心理反應方面亦呈現放鬆效果。然而，目前尚未有接觸台灣國產木材同時檢測生理及心理兩方面數據的實證研究來佐證國產木材之生心理效益。又，林務局近年來積極推動國產材利用，若有相關實證研究，將可協助國產材的推廣及應用。故本研究藉由檢測受測者生理及心理的變化，探討手掌與腳掌接觸國產針葉樹種台灣杉（Taiwania cryptomerioides）及闊葉樹種相思木（Acacia confusa）之木材，與台灣常見塗裝PU漆處理之臺灣杉與相思木，以及表層經過仿木處理之塑膠，並用常見建材磁磚做為對照，觀察人體接觸不同材料對生心理反應所造成的影響。此研究結果發現，手掌接觸材質時，接觸台灣杉與磁磚時的心率有所不同，且接觸塗漆相思木與台灣杉時心率變異度（Heart Rate Variability，HRV）的高頻（High Frequency，HF）數值有顯著差異；腳掌接觸PU塗漆相思木的心率與接觸磁磚、相思木、台灣杉與PU塗漆台灣杉皆有顯著差異，且接觸相思木與接觸磁磚及台灣杉時的舒張壓有顯著差異，而相思木的HF與PU塗漆相思木有所差異；不論手掌或腳掌接觸自然材質，在生理回饋上皆可觀察到與接觸人工材質有顯著的差異。而心理評價方面，不論手掌或腳掌接觸，受測者皆認為自然材質、上漆處理過的自然材質以及經過仿木處理的塑膠，比人工對照材料磁磚要「舒服」、「放鬆」、「自然」、「溫暖」、「粗糙」且「柔軟」。

Touching natural wood is empirically known to have a pleasant and comfortable feeling. Previous studies reported that comparing touching natural woods and touching artificial materials with the palm, touching woods resulted in decline of the systolic blood pressure, heart rate and induced a physiological relaxation, also in the subjective psychology responded the aspect also presents the relaxation effect.
However, there is no research about psychophysiological effects of touching Taiwanese domestic woods. On the other hand, the Forestry Bureau has been actively promoting the use of domestic woods in recent years. If relevant empirical research is available, it may contribute in the promotion and application of domestic woods. Therefore, this study recorded physiological and psychological activities of 41 participants, exploring the contact between palm/soles and domestic woods, Taiwan fir (Taiwania cryptomerioides) and Acacia wood (Acacia confusa), PU-coated Taiwan fir and Acacia, wood-like plastic, and tiles as the comparison to clarify the psychological responses of touching different materials. The results of this study found the heart rate is significantly different between touching Taiwan fir and touching tile by palm. There is a significant difference in the results of high frequency (HF) of heart rate variability (HRV) between touching coated Acacia and touching Taiwan fir. Touching coated Acacia with soles, the heart rate is significantly different from that of contact with tiles, Acacia, Taiwan fir and coated Taiwan fir, and the HF value has significant differences between touching Acacia and coated Acacia wood. No matter the object is palm or soles, there are significant differences between natural materials and artificial materials when it comes to physiological feedback. For the psychological evaluation, either palm or soles, touching natural materials, the coated natural materials, and the wood-like plastic, the subjects reported it is more "comfortable", "relaxed", "natural", "warm", "rough" and "soft" than tile.
