S08 EOG 1

In EOG 1, students record horizontal eye movement and observe eye fixation and tracking. Students perform a number of tasks that allow them to record the duration of saccades and fixation. Students also record spatial position of eye movements.

• National Science Education Standards Correlation

Experimental Objectives

1. Record EOG on the horizontal plane and compare eye movements under the following conditions: pendulum tracking, pendulum simulation, reading silently, reading aloud, and reading challenging material.
2. Measure duration of saccades and fixation during reading.
3. Optional: explore microsaccadic eye movement.

Tasks Performed by the Student

• Record horizontal EOG.
• Track pendulum movement with eyes only, trying not to move head or blink.
• Simulate pendulum movement (decreasing swing cycles) with eyes only.
• Read Passage 1 (easily understandable material) silently (to self) for 20 seconds.
• Read Passage 2 (challenging material) silently (to self) for 20 seconds.
• Read Passage 1 aloud.
• Optional: Focus on an on-screen guide; position of guide represents point of focus.
