Subclaims¶

q3 i3 High-frequency target words had shorter total fixation durations, gaze durations, regression path durations, and lower probability of regressions out than low-frequency words. → Miriam Rivero-Contreras 2023

Evidence¶

Miriam Rivero-Contreras 2023¶

Miriam Rivero-Contreras, Paul E. Engelhardt, David Saldaña. (2023). Do easy-to-read adaptations really facilitate sentence processing for adults with a lower level of education? An experimental eye-tracking study. Learning and Instruction 84 (2023) 101731. https://doi.org/10.1016/j.learninstruc.2022.101731

q3 · i3 · causal · r2

Mixed ANOVAs on target-word measures in the 2×2×2 experiment with 60 adults; Frequency main effects were large: Target total fixation η²p = .68, Target gaze η²p = .65, Regression path duration η²p = .76 (all p < .001). "the high-frequency words had shorter total fixation durations, gaze durations, regression path durations."

"the high-frequency words had shorter total fixation durations, gaze durations, regression path durations, and a less probability of regressions out than low-frequency words"

Related Claims¶

• Lexical simplification benefits non-university adults more than university adults, though it helps both groups — a narrower finding that bears on this claim

• Unknown words are read significantly longer than known control words in all four eye-tracking measures — related
• Reading times for unknown words decrease significantly after three to four encounters, and by eight encounters unknown words are read like known words — related
