“…Indeed, a beneficial effect of verbal rehearsal and elaboration on memory performance has been reported for both verbal (Craik & Tulving, 1975;Darley & Glass, 1975;Maki & Schuler, 1980) and visual materials (Bartlett, Till, & Levy, 1980;Daniel & Ellis, 1972;Ellis & Daniel, 1971). However, as has been shown by a number of studies in which visual materials were used (see, e.g., Bahrick & Boucher, 1968;Bartlett et al, 1980;Nelson & Brooks, 1973;Schooler & Engstler-Schooler, 1990), the effect of facilitation cannot be regarded as a general phenomenon.…”
