Subclaims¶

q3 i? Performance on Easy tasks remained consistently high regardless of ADHD status or segmentation condition, with low error means and restricted hesitation range, so Easy tasks were excluded from H2–H4 analyses. → Veronica Pimenova 2026

q3 · i? · causal · r2

Preliminary analysis of the within-subjects study data revealed a significant floor effect on Easy tasks across all participants. After removal, the final dataset for H2, H3, and H4 consisted of N=104 observations across Medium and Hard difficulty levels.

"performance on these tasks remained consistently high, with low error means below 0.20 (𝑀Control = 0.20,𝑀ADHD = 0.18) and low hesitations showing a restricted range of [0–1]."

Discussion¶

Related Claims¶

• Segmentation increases learning time — the general claim this finding bears on, with the studies behind it
• Task difficulty increases error counts, with significantly more errors on Medium and Hard tasks than Easy tasks — related
• In one 51-learner experiment on help formats in computer-based electrical engineering instruction, far-transfer scores were at the floor in every condition, and time spent on instruction did not differ significantly between conditions — related
• Task difficulty increases hesitations, with significantly more hesitations on Medium and Hard tasks than Easy tasks — related
• Segmentation reduces errors and hesitations for participants with and without ADHD, with larger point estimates for the ADHD group but no significant segmentation-by-ADHD interaction — related
• Theoretical quality of both theory-based and non-theory agents remains stable across Easy, Medium, and Hard scenario difficulty levels — related
