我们目前的环境的特点是无处不在的食物线索。真实的食物的视觉和气味，以及对开胃食物的图形描述，可以引导我们的饮食行为，例如，通过引发食物渴望和影响食物选择。视觉食物线索对人类信息处理的相关性已经被越来越多的研究所证明，这些研究采用了心理学，医学和神经科学等学科的食物图像。然而，目前使用的食物图像集在实验室和图像特征（对比度、亮度等）之间变化很大。和食物成分（卡路里、常量营养素等）往往不明确。这些因素可能导致了这项研究的一些不一致之处。为了解决这个问题，我们开发了food-pics，这是一个图片数据库，包含568张食物图像和315张非食物图像，沿着详细的元数据。来自德语国家和北美的年龄和体重差异较大的N = 1988人提供了效价、唤醒、适口性、进食欲望、可识别性和视觉复杂性的规范性评级。此外，还提供了关于常量营养素（g）、能量密度（kcal）和物理图像特征（颜色组成、对比度、亮度、尺寸、复杂性）的数据。food-pics图像数据库在creative commons许可下免费提供，希望该数据集将促进标准化和跨研究的可比性，并推进关于饮食行为决定因素的实验研究。
Our current environment is characterized by the omnipresence of food cues. The sight and smell of real foods, but also graphically depictions of appetizing foods, can guide our eating behavior, for example, by eliciting food craving and influencing food choice. The relevance of visual food cues on human information processing has been demonstrated by a growing body of studies employing food images across the disciplines of psychology, medicine, and neuroscience. However, currently used food image sets vary considerably across laboratories and image characteristics (contrast, brightness, etc.) and food composition (calories, macronutrients, etc.) are often unspecified. These factors might have contributed to some of the inconsistencies of this research. To remedy this, we developed food-pics, a picture database comprising 568 food images and 315 non-food images along with detailed meta-data. A total of N = 1988 individuals with large variance in age and weight from German speaking countries and North America provided normative ratings of valence, arousal, palatability, desire to eat, recognizability and visual complexity. Furthermore, data on macronutrients (g), energy density (kcal), and physical image characteristics (color composition, contrast, brightness, size, complexity) are provided. The food-pics image database is freely available under the creative commons license with the hope that the set will facilitate standardization and comparability across studies and advance experimental research on the determinants of eating behavior.
