Description of the methods for collection/generation of data: Experimental methodology and primary data collection. Thirty-two volunteer undergraduate students took part in a repeated-measures experiment that used Eye-Tracking technology to manipulate three factors: the type of stimulus (visual or semantic), the emotional valence (positive, neutral, or negative), and the temptation (absence or presence). Reaction time, eye fixation patterns, and pupil dilation served as indicators of cognitive and emotional load. 2. Data processing methods From the original raw dataset, 9 matrices were created, which contain data on the main variables of the study and their combinations. Following data preprocessing, we initiated a descriptive examination of the variables of interest across the experimental factors, and to analyze differences and combinations between the factors across each dependent variable, several repeated-measures ANOVAs were performed. 3. Software or instruments needed to interpret the data: For statistical analysis, we used the Jamovi software (version 2.6; The Jamovi Project, 2024). 4. Standards and calibration information, if appropriate: Participants were seated in front of the monitor with the eye-tracker discreetly integrated. The procedure included: digital informed consent via QR code, gaze calibration (based on eye-tracking technology, where the user follows a series of points that appear and move randomly across the screen for a few seconds), self-paced reading of instructions, task demonstrations, and 48 counterbalanced experimental trials. 5. Environmental or experimental conditions: The experiment was conducted in an environmentally controlled room in accordance with the system manual (Tobii, 2014). The conditions described in that manual include appropriate levels of natural light, space free from external noise, a limited number of researchers present in the experimental room, etc. Stimuli were presented via software on a 15.6" Ultra HD monitor with a resolution of 1920 × 1080 pixels.
