Ultra-processed food and unprocessed/minimally processed food emotional responses dataset

Dataset of Brazilian participants (University students). Participants (n= 174; 144 women; mean age = 20.7 years; standard deviation = 4.35) performed two tasks. In the first task, 16 pictures of foods (8 UPF and 8 UMPF), and 74 pictures from other affective categories (from the International Affective Pictures System, IAPS; Lang, Bradley & Cuthbert, 2008), were presented. After viewing each picture, the participants rated it along two basic dimensions of emotion through the Self-Assessment Manikin scale: pleasantness and arousal. In the second task, the participants viewed the same food pictures, and they rated their intention to consume the foods depicted in the pictures. The dataset contains:
1) Table 1 with information about the level of emotional evocativeness of each picture (food pictures and pictures from IAPS).
2) Table 2 with information about the affective ratings per participant.
3) Table 3 with information about the intention to consume ratings per participant.

本数据集的受试群体为巴西大学生。本次研究共纳入174名参与者（其中144名女性，平均年龄20.7岁，标准差4.35），所有参与者完成两项任务。
第一项任务中，共呈现16张食品图片（8张超加工食品（Ultra-Processed Food, UPF）、8张非超加工食品（Non-Ultra-Processed Food, UMPF）），以及74张取自其他情感类别的图片（来自《国际情感图片系统（International Affective Pictures System, IAPS）》；Lang、Bradley与Cuthbert，2008）。参与者在观看每张图片后，需通过自我评定模拟人量表（Self-Assessment Manikin scale），从情绪的两个基本维度——愉悦度与唤醒度——对图片进行评分。
第二项任务中，参与者再次观看前述食品图片，并对自身食用图中所示食品的意愿进行评分。
本数据集包含以下内容：
1. 表1：各图片（含食品图片与IAPS来源图片）的情绪唤起程度相关信息；
2. 表2：每位参与者的情感评分相关信息；
3. 表3：每位参与者的食用意愿评分相关信息。
