Retroactive interference (RI) in prose learning was investigated in an experiment where passages were constructed on the basis of a predetermined logical structure. This structure made it possible to operationally define similarity and assess the effects of RI for inferential information as well as that stated directly in the original passage.…

An experiment designed to test the generality of Paivio's two factor theory of meaning to sentence comprehension was carried out, and two scoring procedures were investigated: a verbatim score in which sentence elements had to be recalled exactly as they appeared in the original, and a substance score in which synonyms were accepted. The subjects…

A cross-sectional study that investigated memory variables in 100 subjects in 4 age ranges (17-22, 40-50, 60-70, and 75-99) found that the 60-70 year olds were more impaired with respect to retrieval than storage and the major problem with memory among the 75-99 year olds was retrieval from short- or long-term memory. Because the study was…

A report on learning psychology and its relationship to the study of school learning emphasizes the increasing interaction between theorists and educational practitioners, particularly in attempting to learn which variables influence the instructional process and to find an appropriate methodology to measure and evaluate learning. "Learning…

The study sought to use Jensen's two-level theory of mental abilities to predict some hitherto unknown or unnoticed phenomena--facts about which the theory should yield clear-cut predictions and which are not as clearly predictable from other theories, though they may receive ad hoc explanations after the fact. From the two-level theory of mental…
