Explored the relative effectiveness of four modes of delivery (live, video-audio, audio, and manuscript) on content retention among Black college students. Did not find significant differences in retention among the four experimental groups. Attributes the absence of differences to the small amount retained in general. (GC)

Reports three experiments investigating the relationship of the suffix effect and echoic memory. Shows that echoic memory persists for at least 20 seconds. Illustrates that echoic memory can be used to establish a more effective nonechoic memory. Shows that recency recall is higher to auditory than to visual items. (PMJ)

An investigation of a saturation advertising campaign to acquaint the public with changes in radio wavelengths showed that repeated presentation of material does not lead to learning unless appropriate encoding occurs. Such encoding will occur when subjects are allowed to use previously acquired learning strategies. (PMJ)

Examined the extent to which maternal linguistic input enabled children to use syntactic bootstrapping. Studied uses of 25 common verbs in speech of 57 mothers to their 1-year olds and 2-year olds. Found that verbs can be used to create informative syntactic frames, syntactic frames can cue appropriate verb class, and multiple syntactic framing…

Redundancy, defined as shared information, was proposed as an explanatory variable that considers the relationship between information in three channels: the audio, the nonverbal pictorial, and visual-verbal print channel. It was hypothesized that pictures would…
