Periodic letter strokes within a word affect fixation disparity during readingStephanie Jainta
Leibniz Research Centre for Working Environment and Human Factors, Dortmund, Germany
J Vis 10:2. 2010..The findings help to explain the longer reading times reported for words and fonts with high auto-correlation and may also begin to provide a causal link between poor binocular control and reading difficulties...

Binocularity during reading fixations: Properties of the minimum fixation disparityStephanie Jainta
Leibniz Research Centre for Working Environment and Human Factors, Ardeystrasse 67, 44139 Dortmund, Germany
Vision Res 50:1775-85. 2010..Generally, we found fixation disparity to be correlated between conditions of reading and fixating single targets, while the reading fixation disparity tended to be more crossed (eso)...
Accommodation modulates the individual difference between objective and subjective measures of the final convergence step responseS Jainta

Ocular accommodation and cognitive demand: an additional indicator besides pupil size and cardiovascular measures?Stephanie Jainta
Institut fuer Arbeitsphysiologie an der Universitaet Dortmund, Ardeystrasse 67, D 44139, Dortmund, Germany
J Negat Results Biomed 7:6. 2008..Cognitive demand was varied by presenting monocularly numbers at a viewing distance of 5 D (20 cm) which had to be read, added or multiplied; further, letters were presented in a "n-back" task...
Objective and subjective measures of vergence step responsesS Jainta
Institut für Arbeitsphysiologie an der Universitaet Dortmund, Ardeystrasse 67, D 44139 Dortmund, Germany
Vision Res 47:3238-46. 2007..The dynamic nonius test is therefore considered to be useful to relatively evaluate a subject's ability in disparity vergence...

Institut fur Arbeitsphysiologie, Ardeystrasse 67, D 44139 Dortmund, Germany
Ophthalmic Physiol Opt 24:520-7. 2004..12 D for the accommodation data. Interindividual reliabilities were satisfactory. However, the PR II did not provide a continuous stream of data and the specified sampling frequency of 25 Hz was rarely realized...
Capture of visual direction in dynamic vergence is reduced with flashed monocular linesWolfgang Jaschinski
Institut fur Arbeitsphysiologie, Ardeystr 47, D 44139 Dortmund, Germany
Vision Res 46:2608-14. 2006..In conclusion, if one wishes to estimate the dynamic vergence response with psychophysical methods, effects of capture of visual direction can be reduced by using flashed nonius lines...
Horizontal fixation disparity measures with nonius linesWolfgang Jaschinski
Institut fur Arbeitsphysiologie, Dortmund, Germany
Optom Vis Sci 82:988-99. 2005..g., dynamic or forced vergence. Nonius lines may be valid at larger spatial separation between fusion contour and nonius lines. Therefore, we measured fixation disparity varying the amount of a vertical gap between nonius lines...
Relation between fixation disparity and the asymmetry between convergent and divergent disparity step responsesWolfgang Jaschinski
Institut fur Arbeitsphysiologie, Ardeystr 47, D 44139 Dortmund, Germany
Vision Res 48:253-63. 2008..static under-convergence) had a weaker dynamic response for convergent than for divergent step stimuli. This confirms a relation between static vergence and asymmetric dynamic vergence, which both are idiosyncratic vergence parameters...
Objective vs subjective measurements of dark vergenceWolfgang Jaschinski
Institut fur Arbeitsphysiologie, D 44139 Dortmund, Germany
Ophthalmic Physiol Opt 27:85-92. 2007..Thus, the nonius test is sufficient for a subjective estimation of dark vergence...
