Reports three experiments demonstrating that recall for words increases with deeper levels of processing and with longer rehearsal intervals. Asserts that there is no interaction between those strategies. (PMJ)

Reports on an experiment in which performance on abstract and concrete sentences was compared in a sentence meaning classification task and in a free recall task. Results show that concrete sentences were classified significantly faster than abstract ones. (CLK)

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.

Experiments are reported in which semantically interrelating sentences were presented to subjects as discrete items, and inference tests were given to measure the degree to which the similar information had been stored in the same memory system. Results suggest that verbal information is sometimes encoded into an episodic system. (Author/RM)

Reports three experiments to test age-related difFerences in sentence memory arising from sources other than noncognitive factors. Age-related differences are discussed in terms of deficiencies at encoding and retrieval. (PMJ)
