Monitoring the gaze of infants and children can provide powerful insights into the development of cognitive, linguistic and social processes, but young participants create a number of challenges for eye tracking researchers - not least in participant setup, experimental design and data analysis. In this unique course, learn how to get the most out of your SR Research EyeLink system when working with infants and children.
Eye tracking infants and children presents a number of challenges, but recent advances in hardware and software mean that working with young participants is no longer synonymous with frustration and data loss. This advanced workshop is aimed at EyeLink users who want to ensure that their eye tracking systems, tasks and analysis approaches are optimised for infant and child research. The workshop will cover hardware and set up issues, including optimal layout for the testing environment, using the arm-mount and desktop mounts, and using Remote Mode, as well as working with custom calibration targets.
The course will demonstrate how to program experiments for infant and child research in Experiment Builder, including detailed discussion of gaze-contingent triggers, preferential viewing tasks, accumulated looking, habituation and other common tasks. The course will also cover issues for data analysis that may arise when working with infants. Worked examples, including video stimuli, Experiment Builder scripts and Data Viewer analysis sessions will be provided.
We will begin with an introduction outlining the key topics that will be addressed in the workshop - the importance of optimal physical set ups, maintaining participant attention, flexible experiment programming and robust data analysis.
This will be a practical demonstration of working with both Arm and Desktop mounted EyeLink systems when testing infants and children. The session will include how to use appropriate animated calibration targets and how to choose the appropriate calibration model.
This will be a practical introduction to setting up a basic infant friendly preferential looking experiment, including how to play a choice of videos during camera set up, the use of animated calibration targets, gaze contingent trial triggering, responsive trial recycling and effective use of attention getters.
This will consist of a practical demonstration of using advanced Experimental Builder functionality to program accumulated looking / habituation type tasks.
Learn how to calculate tracking loss, exclude trials and manually adjust fixations / saccades.
Learned tips and tricks for setting up and calibrating EyeLink systems to record data from children and infants.
Understood how to use Data Viewer to deal with common issues such as missing data.
