Results of hierarchical linear models: Primary oculomotor effects.

Dependent Variables. RATE: Reading speed in words/min (higher = better); FIX: Number of fixations (lower = better); LEFT: Number of regressive saccades (lower = better); TOT: Total number of inefficient saccades (lower = better); UP: Number of gaze motions up (lower = better); DN: Number of gaze motions down (lower = better); OUT: Number of gaze motions off-page (lower = better). Effects. Device (1 = POD, 0 = PAD); Crowding (1 = SPACED, 0 = NORMAL); Hand (1 = HAND, 0 = NO-HAND); High Reading (1 = yes, 0 = no).
