Pupil dilation as specific marker of cognitive effort in the memory domain: an eye‐tracking study in younger and older adults
Our findings suggest that pupil dilation is not a general marker of cognitive effort but can be specifically sensitive to memory load. Moreover, the results are in line with the idea that larger PD may reflect age-related compensatory mechanisms, occurring in a task-specific fashion. In conclusion, the study offers novel hypotheses on the role of the LC-NA system in cognitive function and its decline.
