Repeated sentence presentations inflate perceived benefit and deflate perceived deficit

Evidence

Ratings increase near linearly as a function of ΔSNR, and are asymmetric: when the + ΔSNR interval preceded the reference, ratings were less than when the + ΔSNR interval followed the reference (e.g., when the second interval was the better SNR, ratings were greater than one increment at a ΔSNR of 4 dB, but when the second interval was the worse SNR, ratings were greater than one increment only when ΔSNR was 8 dB). This asymmetry was most likely due to an order effect; the second iteration of a sentence has been shown to be more intelligible (e.g., Thwing 1956 ), hence second-interval deficits would be deflated, and second-interval benefits inflated. — Dijk, Pim van, Physiology, Psychoacoustics and…, 5686

• QUESTION: The familiarity/intelligibility boost from sentence repetition is cited from 1956 — worth probing the mechanism and whether modern intelligibility research has refined this.
