Saccadic eye movements during a concurrent auditory task
TLDR
Results indicated there was both an elimination of discrete saccades and a shortening of eye movement paths in an experiment in which they simultaneously visually tracked a jumpwise moving target and identified randomly generated auditory dots and dashes.Abstract:
Ten adult male subjects participated in an experiment in which they simultaneously visually tracked a jumpwise moving target and identified randomly generated auditory dots and dashes. Results indicated there was both an elimination of discrete saccades and a shortening of eye movement paths. It was also observed that the difficulty of the visual tracking task and the concurrent auditory task showed effects that were not independent of each other. Results could be construed to support both a divided attention and an opponent-process visual processing model.read more

Saccadic eye movements and dual-task interference
TL;DR: Four dual-task experiments required a speeded manual choice response to a tone in a close temporal proximity to a saccadic eye movement task, and the findings might reflect the fact that eye movements can be directed by two separate brain systems.

Effect of a Concurrent Auditory Task on Visual Search Performance in a Driving-Related Image-Flicker Task
TL;DR: Slow overall responses to scenes involving driving-unrelated changes suggest that the underlying process affected by the concurrent auditory task is strategic in nature, and the development of safer in-vehicle communication devices is possible.

TL;DR: The production of this simple set of movements may be partly described by a cascade-type process of parallel analysis of spatial information for eye and hand control, but is also, later in the movement, assisted by cross-system interaction.

Dual-tasking: Is manual tapping independent of concurrently executed saccades?
TL;DR: These reactive saccades were expected to act as a strong perturbation event to the continuous tapping, but the experimental data did not reveal a considerable interference in this specific oculo-manual dual-task experiment.

Pupil Size in Relation to Mental Activity during Simple Problem-Solving
Eckhard H. Hess,James M. Polt +1 more
TL;DR: Changes in pupil size during the solving of simple multiplication problems can be used as a direct measure of mental activity and shows that mental activity is closely correlated with problem difficulty, and that the size of the pupil increases with the difficulty of the problem.

TL;DR: Increases in the size of the pupil of the eye have been found to accompany the viewing of emotionally toned or interesting visual stimuli, and a technique for recording such changes has been developed.
