Impact of web accessibility on cognitive engagement in individuals without disabilities: Evidence from a psychophysiological study
Fig 5
Interaction effect of working memory capacity, heart rate variability and cognitive enhancement on the time-on-task.
The graph shows the relationship between users’ working memory capacity and heart rate variability while reading websites with and without cognitive accessibility enhancements depending on the time-on-task epoch. Dot-dashed lines present slopes for the relationship between working memory capacity and HRV when reading websites with cognitive accessibility enhancement. Solid lines represent the slopes for the same relationship while reading websites without cognitive accessibility enhancements.
