Annotated Eye-Tracking Data for Attention and Inattention in ASD

This data included a total of 20 children with mild to moderate ASD (ASD n = 20, mean age = 8.57, SD = 1.40), 16 boys and 4 girls within the age of 7–11 years. The participants were recruited from an Autism School in Doha and Qatar Autism Society. All the participants had a formal diagnosis of mild to moderate ASD and met the requirements for the American Psychiatric Association’s Diagnostic and Statistical Manual of Mental Disorders (DSM IV). All participants reported normal vision. 

Eye-tracking data were recorded using a screen-based Tobii X2-60 eye-tracking device with a sampling rate of 60 Hz. The Eye-tracking device was attached to the base of the 24-inch computer screen set aside for each participant. The visual attention task was simulated with a desktop virtual reality application that presents a continuous performance test (VR-CPT). This test simulates a conventional learning environment with a teacher in front of a classroom, other students seated, ceiling lights, windows, and a door. The VR-CPT presents distractors similar to that of a real classroom simultaneously with random alphabets displayed on the board. The random letters are used as the target stimuli in this experiment where the participant needs to press the clicker when the letter X appears and ignores other letters.
