Dataset of natural conversations about appearance using fNIRS

In this dataset, we collected brain data from 31 female participants (aged 19.55 ± 0.89 years) using a 40-channel portable near-infrared device during fat talk and non-fat talk (topics such as travel and home decoration), primarily covering the frontal and parietal areas.本数据集从31名女性受试者处采集脑功能数据，受试者年龄为19.55±0.89岁；实验过程中，受试者分别开展减肥闲聊（fat talk）与非减肥闲聊（话题涵盖旅行、家居装饰等），采集环节采用40通道便携式近红外设备（near-infrared device），采集区域主要覆盖额叶与顶叶皮层。
