1. The Effects of Line Spacing
on Eye Movements and
Comprehension
Ellen Wu and Rong Xiang
Introduction
Hypothesis: Increasing line spacing results in increased fixation
duration and thus, increased reading comprehension.

Discussion
● Lack of correlation between line spacing,
fixation duration, and comprehension
levels
● Future experiments
● Practical application
2. PSA Text Placement
Emma Leeds, Raje Enjeti, Rachana
Balasubramanian, Jessica Mui
PSAs: Public Service Announcements
Hypothesis: Text placement at top would create longer fixations
and thus higher comprehension than if text was at the bottom

Eye Movements when Lying
Saavan Chintalacheruvu &
Nevil Abraham
Introduction
● Common notion that eyes focus on top-left when lying
● Some experimental evidence supporting this
Materials & Methods
Results: Average Fixation Duration
● T:360 ± 370 milliseconds
● L: 370 ± 4.0x10^2 milliseconds
● p = 0.468
Possible Errors/Improvement
● Nature of the stimulus
o Why do people lie?
o People usually lie to people
o not a good representation of lying
● Improvement
o Lie to an actual human being
o Give participants a reason to lie
Conclusion
● No correlation within the experiment’s parameters
● However:
o data was highly variable
o results are inconclusive
o must be repeated with improvements
The Antisaccade Task Under
Changing Fixation Points
Grace Chen, Cynthia Guo, Bum
Shik Kim, Kang Woo Kim
What is an antisaccade?
Saccade
● Inhibition of reflexive saccade
● Frontal cortex ability
Antisaccade
Hypotheses
Antisaccade ability will vary with:
1. stationary vs.
moving fixation
point
2. moving in opposite vs.
same direction as cue
vs
vs
Experimental Design

Analysis of Results
General Conclusions

●
●
Eye patterns remain steady under varied conditions
Moving fixation point reduced antisaccade ability
Dynamic feedback between eyes and cognition
High variability between participants
