Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q3 i? Lexical categorization training produced statistically significant pre-to-post reading speed increases in all three experiments (26.6%, 20.4%, and 22.4% mean gains). → Benjamin Gagl & Klara Gregorová 2024

Table 1 reports pre-to-post SLS reading-speed changes in percent for the three experiments, with two-sided t-tests against zero. Experiment 1 and Experiment 2 lexical categorization (LC) training both reached significance: "2.62 (2.37) 16 (15) .018 (.035)" and t(26) = 2.65, p = .014; parentheses show outlier-corrected values. Values are percent change, not standardized effect sizes.
"Experiment Condition M SD t DF p 1 Lexical categorization (LC) training 26.6 (20.5) 41.8 (34.6) 2.62 (2.37) 16 (15) .018 (.035) 2 LC training 20.4 (16.1) 40.2 (33.9) 2.65 (2.42) 26 (25) .014 (.023)"
Discussion¶
Learner Variables¶
- Reading Fluency — outcome: instruction changes it
Related Claims¶
- A font-change variant of lexical categorization training significantly increased reading speed, but not significantly more than lexical categorization training alone — related
- Phonics control training did not significantly increase reading speed in language learners and did not differ significantly from lexical categorization training — related
- Training response times rise with lexical categorization uncertainty and fall across sessions, but a reduction of the uncertainty effect across sessions appears only in Experiment 1 — related
- An individualized machine-learning diagnostic using LCM-based features predicts lexical categorization training benefits with moderate-to-good accuracy — related
