Subclaims¶

q3 i? In a two-task design, sequence position impeded initial Vernier performance, left shape search unaffected, and produced no retrograde interference in either task. → Jia Yang 2025

Experiment 2 (N = 14, two groups trained in Vernier and shape search in opposite orders, with next-day re-test): "anterograde interference was evident in the Vernier task, while independence was observed in the Shape task"; the Vernier sequence-position coefficient on initial performance was −0.09.

"In summary, anterograde interference was evident in the Vernier task, while independence was observed in the Shape task. Furthermore, no retrograde interference was detected in either task."

Discussion¶

Related Claims¶

• Later sequence position worsens initial performance in low- and mid-level perceptual tasks (Experiment 1A) — related
• No retrograde interference: forgetting after months is comparable for early- and late-trained tasks (Experiment 1B) — a broader claim this one bears on
• Shape search and N-back tasks show no sequence position effect in session-level analysis — related
