Abstract

Common brain areas play a role in processing both personality and odor, while personality theory predicts that olfactory performance should vary according to personality traits. The Big Five model of personality is considered a gold standard measure but has yet to be directly applied in investigations linking personality and olfactory responses. Moreover, olfactory measures commonly used in personality studies are usually rudimentary sensory performance indices such as thresholds as opposed to higher-order perceptual and psychological metrics.

This cross-sectional study examined the relationship between comprehensive measures of personality and perceptual responses to odors. Personality was measured using a comprehensive test of the Big Five model of personality, while olfactory responses included identification, pleasantness, perceived intensity, and familiarity. Odors were presented using the Sniffin’ Sticks test.

Small to moderate correlations were noted between aspects of personality and response to odor, even after controlling for participant (N?=?74) characteristics such as age and gender. Regression analyses indicated that, overall, odor familiarity co-varies the most with aspects of personality.

Responses to olfactory stimuli are moderated by specific personality dimensions. This finding is consistent with approach and avoidance motivational models of personality.

个性和对常见气味的感知

大脑的共同区域在处理人格和气味方面都发挥着作用，而人格理论预测，嗅觉表现应该根据人格特征而变化。大五人格模型被认为是黄金标准测量，但尚未直接应用于将人格和嗅觉反应联系起来的调查。此外，人格研究中常用的嗅觉测量通常是基本的感官表现指标，如阈值，而不是高阶的感知和心理指标。这项横断面研究考察了人格综合测量和对气味的感知反应之间的关系。性格是用大五人格模型的综合测试来衡量的，而嗅觉反应包括识别、愉悦、感知强度和熟悉度。使用嗅探棒测试来呈现气味。即使在控制了参与者(N = 74)的年龄和性别等特征之后，个性方面和对气味的反应之间也存在小到中度的相关性。回归分析表明，总体而言，气味熟悉度与个性方面的协变最大。对嗅觉刺激的反应受到特定人格维度的调节。这一发现与人格的接近和回避动机模型是一致的。
