In the present study, we examined correlation between foveal and parafoveal processing efficiency and global eye movement parameters in reading. Foveal processing efficiency was assessed by the performance accuracy in a speeded lexical decision task, where 5-7 -letter words and pseudowords were presented backward-masked for identification using exposure times of 80, 60, 40 and 20 ms. Parafoveal processing efficiency was assessed by a lexical decision task, where 5-letter words and pseudowords were presented for 120 ms .91, 1.33, 1.83 and 2.24 degrees of visual angle to the right and left of the fixation point. Participants read silently for comprehension 8 popular science texts on different topics. Average forward saccade amplitude, forward fixation duration, forward number of fixations and regression rate were used as global indices of reading efficiency. Preliminary results showed a moderate positive correlation for forward saccade amplitude with foveal processing efficiency but no correlation with parafoveal processing efficiency. Average forward fixation duration displayed a weak positive correlation with parafoveal processing efficiency but not with foveal processing efficiency. Number of forward fixations demonstrated a weak negative correlation with foveal and parafoveal processing efficiency. Regression rate displayed a weak negative correlation with parafoveal processing efficiency but not with foveal processing efficiency. Finally, foveal processing efficiency correlated strongly with the efficiency of parafoveally recognizing words presented in the right visual field but weakly with the efficiency of parafoveally recognizing words presented in the left visual field. Before drawing firmer conclusions, the observed correlations will be confirmed with additional data. [ABSTRACT FROM AUTHOR]
