3 Outline  Field Observations  Behavior and Affective Categories  Data Collection Sheet  Driver Anxiety Parallel Video Capture

4 Field Observations  Based on quantitative field observation method in (Baker et al, 2004; Rodrigo et al, 2007)  Students used the software in groups of 10, one computer per student  Two coders observed each student for 20 seconds, moved on to the next student, circled back to the first student  Observers were synchronized by a common timekeeper

5 Field Observations  Observers coded only one behavior and affective state per time slice  Only the first behavior and affective state were coded  Observers stood diagonally behind the subjects  Observers stood still or moved, depending on the better vantage point
