All visual stimuli were presented on a LCD monitor (BENQ XL2720Z, 1920 × 1080 pixels, 100 Hz vertical refresh rate) calibrated and linearized with a Konica Minolta LS-110 photometer. The subjects sat in front of the monitor at a viewing distance of 57.5 cm and with their head restrained on a chin rest. Their eye position was monitored with an infrared image eye tracker (EyeLink 2000 Desktop Mount, SR Research). Two key buttons were placed in front of the subjects. We used MATLAB (Mathworks) with Psychtoolbox extension53 (link)54 (link) on a PC to present stimuli and collect responses.
Eyelink 2000 desktop mount
Manufactured by SR Research
The EyeLink 2000 Desktop Mount is a high-performance eye tracking system designed for a wide range of research applications. It provides precise and reliable eye movement data capture with a sampling rate of up to 2000 Hz. The system features a desktop-mounted camera and illumination unit that tracks the participant's eye movements while they interact with stimuli presented on a computer screen.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
