Replication Data for: I spy with my little eye

This data set comprises eyetracking data of human visual search patterns when assessing equine facial expressions indicative of various pain levels. Hundred and eight individuals (N=108), classified into three groups (affinity with horses (N=60), pet owners with no affinity with horses (N=32), and individuals with no affinity with animals (N=16) evaluated four photos of horses with different levels of pain, while having their eye moments recorded using eye tracking glasses. Error score, calculated by comparing participant scores to Gold Standard Visual Analogue Score levels and fixation metrics (number of fixations and duration of fixations) were analysed across four Areas of Interest (AOIs) of the horse's face, namely eyes, ears, nostrils, and mouth.

本数据集收录了人类在评估不同疼痛程度的马面部表情时的视觉搜索模式眼动追踪数据。共108名受试者（N=108）被划分为三组：对马具有亲近感者（N=60）、无马类亲近感的宠物主人（N=32）、无任何动物亲近感者（N=16）。受试者需对4张不同疼痛程度的马的照片进行评估，期间通过眼动追踪眼镜记录其眼动数据。研究通过将受试者评分与金标准视觉模拟评分（Gold Standard Visual Analogue Score）进行比对以计算错误评分，并针对马面部的四个感兴趣区（Areas of Interest, AOIs）——眼部、耳部、鼻孔与嘴部，对错误评分及注视指标（注视次数与注视时长）展开分析。
