15.1. Describe the procedure of the experiment. Select first if the procedure refers to the MultiplEYE core data collection or to the collection of additional data.
For the collection of core dataset, please check the box describing the standard MultiplEYE procedure below:
The experiment starts with the experimenter entering the participant ID into the experiment software. Subsequently, the participant is greeted by a welcome screen and prompted to electronically sign the consent form. Following this, the experiment instructions are displayed on the screen. Next, the camera setup is initiated, which includes calibration and validation processes. A practice phase commences, involving two short texts followed by two comprehension questions each. These practice trials serve to familiarize participants with the experimental setup and keyboard usage, as well as to provide practice with comprehension questions. The main phase of the reading experiment starts thereafter. Ten texts are presented in a randomized order, shuffled uniquely for each participant. A fixation trigger precedes the turn to each new page, requiring participants to fixate on a dot on the screen to validate calibration accuracy and allow for a smooth and fast transition to the next page, if the calibration is still sufficiently precise. Re-calibration procedures follow if warranted to regain precision of the eye-tracking measurements. Three rating scales follow the presentation of each text: two inquiring about the participant’s familiarity with the text (rating the familiarity of the text and whether participants have read or listened to the text previously), and the last one inquiring about the perceived difficulty. Following the rating scales, participants are prompted to respond to six comprehension questions after having completely read each text. Re-visitations of the texts are disabled during the presentation of the comprehension questions. After the completion of the experiment phase, participants are asked to fill out a participant questionnaire on a screen.
