“…This contrasts with the situation in the early 1980s, when Berry, Gunter, and Clifford (1982) noted that although earlier studies on visual format had been inconclusive, more consistent evidence was emerging that pictures generally aid learning. These authors cited a number of laboratory findings with simulated or actual bulletins which showed better probed recall of detailed verbal information with still or film pictures than with none (Findahl, 1971;Stauffer, Frost and Rybolt, 1981) or with a 'talking head' (Findahl, 1981;Renckstorf, 1980;Edwardson, Grooms, and Proudlove, 1981). Although Edwardson, Grooms, and Pringle (1976), Sanders (1977), and Gunter (1980) had reported no visual format effects, no studies had shown worse learning with 'enriched' picture forms than with sound-only or 'talking head'.…”
