Friend or Foe dataset

This dataset was extracted from an American game show, Friend or Foe. In this show, pairs of contestants played a variant of the prisoner’s dilemma to decide the allocation of an often-large monetary prize. From video recordings of contestants’ interactions prior to their decision-making, we extract a broad range of multimodal behavioral features (i.e., eye gaze, head pose, facial expressions, body movement, and language characteristics) and socio-demographic information.本数据集提取自美国游戏节目《Friend or Foe》（《朋友还是敌人》）。在该节目中，参赛选手以二人搭档的形式开展博弈，通过囚徒困境（prisoner’s dilemma）的变体规则完成数额往往不菲的货币奖金的分配决策。研究团队从选手决策前的互动视频录像中，提取了涵盖多模态行为特征（即视线轨迹、头部姿态、面部表情、肢体动作与语言特征）以及社会人口统计学信息在内的多维度特征数据。
