Analyses of horizontal and vertical fixation disparities indicated that the most prevalent type of disparate fixation is crossed (i.e., the left eye is located further to the right than the right eye) while the left eye frequently fixates somewhat above the right eye. The Gaussian distribution of the binocular fixation point peaked 2.6 cm in front of the plane of text, reflecting the prevalence of horizontally crossed fixations. Fixation disparity accumulates during the course of successive saccades and fixations within a line of text, but only to an extent that does not compromise single binocular vision. In reading, the version and vergence system interact in a way that is qualitatively similar to what has been observed in simple nonreading tasks. Finally, results presented here render it unlikely that vergence movements in reading aim at realigning the eyes at a given saccade target word.}, language = {en} } @misc{ValsecchiDimigenKliegletal.2009, author = {Valsecchi, Matteo and Dimigen, Olaf and Kliegl, Reinhold and Sommer, Werner and Turatto, Massimo}, title = {Microsaccadic Inhibition and P300 Enhancement in a Visual Oddball Task}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus-57170}, year = {2009}, abstract = {It has recently been demonstrated that the presentation of a rare target in a visual oddball paradigm induces a prolonged inhibition of microsaccades.
