Abstract

This international study aimed to investigate cross-modal associations between parosmic sensations and visual information, as well as explore potential cross-cultural differences; 393 parosmia patients from Argentina, Germany, Japan, and the Philippines participated. The patients were provided with a 63-color chart encompassing diverse hues and a 20-shape chart containing polygonal and curved shapes. Their task was to choose one color and one shape that matched their parosmic sensations. Results indicated that patients generally associated their parosmic sensations with brownish or greenish colors, darker colors, and polygonal or cloud-like shapes. Significant cross-cultural differences were observed, with Germans tending to select darker colors and edged shapes, while Japanese preferred brighter colors and curved shapes. These differences appeared to be related to the intensity of parosmia, which was higher among Germans. The study suggests a cross-modal relationship between olfaction and vision, while also highlighting the influence of cultural factors on parosmia perception.

Practical Applications

The findings of this study have practical implications for understanding and managing parosmia symptoms, particularly in multicultural settings. Healthcare professionals can use the cross-modal associations between olfactory sensations and visual information as a tool for assessment and diagnosis of parosmia patients. By considering the cultural background of patients, healthcare providers can better understand the nuances in their descriptions and interpretations of parosmic sensations. Additionally, the observed cross-cultural differences in color and shape associations can inform the development of standardized assessment tools that are sensitive to cultural variations. This knowledge can enhance communication between patients and healthcare professionals, leading to more accurate diagnosis, personalized treatment approaches, and improved patient outcomes. Furthermore, the study highlights the need for cultural sensitivity in odor-related research and the development of interventions for parosmia and other olfactory disorders.

跨模态和跨文化对方言的认知

这项国际研究旨在调查味觉和视觉信息之间的跨模态关联，并探索潜在的跨文化差异；来自阿根廷、德国、日本和菲律宾的393名嗅觉障碍患者参与了研究。为患者提供了一份包含不同色调的63色图表和一份包含多边形和弯曲形状的20形图表。他们的任务是选择一种颜色和一种形状来匹配他们的味觉。结果表明，患者的味觉通常与褐色或绿色、深色、多边形或云状有关。观察到显著的跨文化差异，德国人倾向于选择深色和边缘形状，而日本人更喜欢明亮的颜色和弯曲的形状。这些差异似乎与戏仿的强度有关，戏仿在德国人中更高。这项研究表明嗅觉和视觉之间存在跨模态关系，同时也强调了文化因素对味觉感知的影响。这项研究的发现对理解和管理言语障碍症状具有实际意义，尤其是在多元文化环境中。医疗保健专业人员可以使用嗅觉和视觉信息之间的跨模态关联作为评估和诊断嗅觉障碍患者的工具。通过考虑患者的文化背景，医疗保健提供者可以更好地理解他们对味觉感受的描述和解释中的细微差别。此外，观察到的颜色和形状关联的跨文化差异可以为开发对文化差异敏感的标准化评估工具提供信息。这些知识可以加强患者和医疗保健专业人员之间的沟通，从而实现更准确的诊断、个性化的治疗方法和改善患者的预后。此外，该研究强调了气味相关研究中文化敏感性的必要性，以及嗅觉障碍和其他嗅觉障碍干预措施的开发。

期刊介绍： The Journal of Sensory Studies publishes original research and review articles, as well as expository and tutorial papers focusing on observational and experimental studies that lead to development and application of sensory and consumer (including behavior) methods to products such as food and beverage, medical, agricultural, biological, pharmaceutical, cosmetics, or other materials; information such as marketing and consumer information; or improvement of services based on sensory methods. All papers should show some advancement of sensory science in terms of methods. The journal does NOT publish papers that focus primarily on the application of standard sensory techniques to experimental variations in products unless the authors can show a unique application of sensory in an unusual way or in a new product category where sensory methods usually have not been applied.
