Data for paper 'Hedonic contrast and the short-term stimulation of appetite' in Appetite (2020)<br>This dataset is from a single experimental study examining the effects of hedonic contrast on food intake in a snack context. Participants (n=96) were assigned at random to one of three conditions where they could eat as much or little as they liked from a sequence of four bowls of snack foods:Palatable - served four bowls of salted crispsBland - served four bowls of unsalted crispsContrast - served salted, unsalted, salted, unsalted in that order.<br>Data are intake (g), rated pleasantness and saltiness for each of the four servings, along with demographic data (age, height, weight and BMI), and individual difference measures (hunger at time of testing, and scores on the Three Factor Eating Questionnaire Restraint and Disinhibition scales, and Barratt Impulsiveness Scale (BIS-11: 3 sub-scales and total score).<br>

本数据集为发表于《食欲》（Appetite）2020年期刊的论文《享乐性对比与食欲的短期刺激》的配套实验数据。
本数据集源自一项单一实验研究，旨在探究零食场景下享乐性对比对食物摄入量的影响。96名参与者被随机分配至三种实验条件之一，参与者可自主调整进食量，面前依次摆放四碗零食：
- 美味组：提供四碗咸脆薯片
- 清淡组：提供四碗无盐脆薯片
- 对比组：按咸脆、无盐、咸脆、无盐的顺序依次摆放薯片

数据集包含四份餐食各自的摄入量（单位：克）、愉悦感评分与咸度评分，同时涵盖人口统计学资料（年龄、身高、体重及身体质量指数（Body Mass Index, BMI）），以及多项个体差异测量指标：测试时的饥饿感评分、三因素饮食问卷（Three Factor Eating Questionnaire）的约束与抑制分量表得分，以及巴瑞特冲动量表（Barratt Impulsiveness Scale, BIS-11，含3个分量表及总得分）。
