Describes three experiments conducted to examine the superior retention of related word pairs when the second word in the pair required active construction by the subject. The results confirm the importance of subjects' checking solution adequacy and of associative relationships in recall. (PMJ)

Reports three experiments to investigate differences in the semantic classification of pictures and words. The data suggest that visual short-term memory and semantic memory operate in semantic-decision tasks though these sources of information differ in characteristics, potential for activation, and level of abstraction.

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)
