This study examined the effect of phenylethyl alcohol (PEA) concentration on quantitative EEG indices and subjective emotional evaluation in women in their 20s. Thirty healthy women were exposed to five PEA concentrations (0%, 0.01%, 0.1%, 1%, 10%) for 20 seconds each, with 21-channel EEG recorded using the international 10-20 system. Indices included change values relative to baseline (CVB) for θ, α, β, γ bands, regional α CVB, frontal α CVB (RFA), frontal alpha asymmetry (FAA), spectral edge frequency CVB (SEF50, SEF90), and a five-item semantic differential (SD) scale (Q1–Q5). Q6 was excluded a priori due to low suitability for PEA's olfactory profile. One-way repeated-measures ANOVA with Greenhouse–Geisser correction and Bonferroni post-hoc tests was applied. No neurophysiological index showed a significant main effect, with only occipital α CVB at a borderline level (p_GG = .090). Among SD items, freshness (Q5) showed a significant main effect (F(4, 116) = 3.960, p_GG = .014, ηp² = .087); however, no pairwise difference reached significance, and the finding is interpreted as a concentration-dependent tendency. Results suggest that concentration effects of single-compound PEA may emerge more clearly through integrated emotional evaluation than through short-term EEG, supporting parallel use of neurophysiological and subjective measurement in fragrance design.

中文摘要:本研究验证了单一化合物苯乙醇（Phenylethyl Alcohol, PEA）的浓度梯度对20-29 岁女性定量脑电图指标与主观情绪评价的影响。研究招募30 名健康20 + 女性受试者，呈现5 种浓度的PEA 刺激（0%、0.01%、0.1%、1%、10%），按照国际10-20 电极系统采用21 通道脑电图设备，每次刺激采集20 秒脑电信号。观测指标包括：θ、α、β、γ 频段相对功率变化率（CVB），各脑区α 波相对功率变化率，额叶α 波相对功率变化率（RFA），额叶α 波不对称性（FAA），频谱边缘频率变化率（CVB_SEF50、SEF90），以及语义差异量表（SD）5 个题项（Q1~Q5，Q6 因与PEA 香气属性匹配度低，在研究前剔除）。统计采用单因素重复测量方差分析，结合Greenhouse–Geisser 校正与Bonferroni 事后检验。结果显示：所有神经生理指标的浓度主效应均未达显著水平，仅枕叶α 波相对功率变化率出现临界统计趋势（p_GG=.090）；语义差异量表第5 题的浓度效应显著(F(4, 116)=3.960, p_GG=.014, ηp²=.087)，但事后检验未检出显著的浓度配对差异，仅可视为浓度依赖趋势层面的探索性结论。研究提示，单一化合物PEA 的浓度效应在综合情绪评价中的表现比短期脑电指标更显著，建议香料与化妆品行业在产品浓度设计中，结合神经生理测量与主观情绪评价两类方法。
