Data from: The influence of packaging on the perception and preference of Peruvian millennials and centennials

Our study aims to determine the effect that different packaging elements have on consumer perception and preference, with the influence of the referential image being more predominant. The experiment exposed two groups of participants (n=30) to 9 stimuli, which were based on the display of different packaging elements (manufacturer, brand, flavor) with the difference in the addition of a referential image for the second group in the three products of the three different food categories. This research used the eye-tracking platform via RealEye webcam to measure visual attention, and a self-administered questionnaire was used to examine perception and preference.本研究旨在探究不同包装元素对消费者感知与偏好的影响，其中参考图像（referential image）的影响更为显著。本实验招募两组被试，每组各30名，向其呈现9组实验刺激。所有刺激均展示了不同包装元素（生产商、品牌、口味），两组的差异在于：第二组在三类不同食品品类的三款产品中额外添加了参考图像。本研究依托RealEye网络摄像头搭建眼动追踪平台以测量视觉注意力，并采用自填式调查问卷评估消费者的感知与偏好。
