ET UPDATE
SP05

Welcome to ET Update-a quarterly newsletter from the Eye Tracking Lab located at the Center for Cognitive Science.

Buckeye eye movements have appeared in two different research presentations this Spring Quarter 2005:

• Demaree, D., Stonebraker, S., Zhao, W., & Bao, L. (2005, April). Learning from where students look while observing simulated physical phenomena. Poster presented at the Ohio Section of the American Physical Society, Dayton, Ohio.
• Ito, K. & Speer, S. (2005, April). The effect of intonation on visual search: An eye-tracking study. Presentation at Experimental Pragmatics: Exploring the Cognitive Basis of Conversation, Cambridge, England.

To download a copy of the Demaree et al. (2005) presentation or to view eye movement videos from various projects in the lab, please visit the Eye Tracking Lab's projects page.

Spring quarter has also included data collection on two continuing projects and two new ones.

• The Psycholinguistics Lab completed the second of three experiments that timelock eye movements to spoken dialogue in order to investigate how listeners make use of the way speakers accent certain words. For example, the results of Experiment 2 demonstrated that if a speaker uses contrastive accents inappropriately, listeners may be "garden pathed" in their visual search for the appropriate object. In sequences like the following:
  (a) First, hang the red onion.
  (b) Next, hang the GREEN drum.
  upon hearing the inappropriate contrastive accent on "GREEN", listeners tend to look to a green onion before looking to the green drum specified in the instruction. These results provide additional evidence that listeners interpret the contrastive meaning of the accent immediately at the adjective and prior to even hearing the object name.
   
• The Cognitive Development Lab is busy collecting eye tracking data from 6- to 7.5-year-olds for an investigation into the development of perceptual encoding.
   
• The Attitude and Social Cognitions Lab is collecting eye movement data to investigate the classical conditioning of attitudes and the mechanism through which it occurs.
   
• The Orthodontics Section of the College of Dentistry is investigating the eye movement patterns that people make when they view faces.

If you have questions about the ET Lab or want to set up an appointment to discuss the possibility of conducting eye tracking research, please send e-mail to Jonathan Slemmer (slemmer.7@osu.edu). To reach the ET Lab, enter Ohio Stadium through the glass doors between Gates 22 and 24. Take the stairs or elevator to the top floor, or follow the signs for the Center for Cognitive Science.

Research in the ET Lab is jointly funded by the Center for Cognitive Science, the Psycholinguistics Lab, NSF, and an OSU Multidisciplinary Seed Grant from the Federation of the Colleges of Arts and Sciences.
