      <subfield code="a">Changes in saccade duration, saccade amplitude and slope of the regression line relating amplitude and duration were assessed during a 2 hour air traffic control simulating task. Our results suggest caution in interpreting saccade velocity change as an index of 'fatigue' since most of the reduction in average saccade velocity may be a secondary to increases in blink frequency</subfield>
