Eye movement control in Turkish: a corpus-analytic approach

Beken Fikri, Figen
In this thesis, the eye movement parameters during Turkish reading were examined in terms of the characteristics of the words. These eye movement parameters were first fixation landing position, first fixation duration, gaze duration, refixation probability and skipping probability. The text characteristics were specified by word length, launch site, word frequency, and word predictability. A corpus-analytic approach was employed in order to achieve a general picture of Turkish reading patterns. The analyses were conducted by using linear mixed model so that random effect variances - subject, sentence and word type - were controlled. The results of first fixation landing position showed that first fixations land around word centers except for sufficiently long words. Mean initial landing position values with respect to word length showed patterns consistent with those reported in previous, cross-linguistic studies. Furthermore, the preferred viewing location (PVL) effect was observed. The findings for first fixation duration were in good agreement with the inverted optimal viewing position (IOVP) effect. Finally, the general results of gaze duration, refixation probability and skipping probability were consistent with earlier findings.
