Syntes: McCarter, Huber & Cowell (2025) — no visual TE for novel meaningless objects

Finding

  1. Across six experiments, no testing effect: restudy ≥ retrieval; in several experiments restudy was significantly better on final recall and/or recognition.
  2. Heavy-handed attempts (delay, whole-object feedback, equated lure exposure, drawing as overt retrieval) still failed to produce TE > restudy.
  3. Aligns with Ferreira & Wimber (2023, DOI 10.1037/xlm0001248): TE for meaningful objects / word–object pairs, absent or reversed for word–squiggle / low-semantic visual materials.
  4. Forces a Does-not-transfer-to bound on C0 for novel meaningless abstract visual materials lacking preexisting semantic scaffolding — does not kill the linguistic/prose main contrast.

Limits

Part-to-part visual associations; schematic 2D stimuli; not classroom prose. Authors discuss semantic-content, novelty, and paradigm-fit accounts.

This claim dies if …

Replicated delayed design on novel meaningless visuals where retrieval-with-feedback reliably beats equal-time restudy under encoding-succeeded conditions.
