Attention Bias Characteristics and Cognitive Mechanisms in Individuals with Insomnia

his dataset contains raw behavioral and eye-tracking data from four experiments of the study "Attention Bias Characteristics and Cognitive Mechanisms in Individuals with Insomnia".Experiments 1, 2, and 3 used E-prime 2.0 to collect behavioral data including reaction time and accuracy, with .edat2 raw files and exported text files, along with corresponding experimental stimuli (in the Pic/ folders). Experiment 4 used an eye-tracking device to record eye movement data such as fixation duration and saccades, stored in .vco format, with supporting stimulus tables and materials.All data collection followed ethical guidelines. All data have been anonymized with no personally identifiable information. The dataset is complete with no missing values or systematic errors, and supports reproducibility of the analyses in the paper.
