This experiment investigated the assumption that children's learning and retention of prose material can be differentially affected by varying discrepancy from expectation (as established by an advance organizer). It was hypothesized that a passage which differed significantly from expectation would produce heightened arousal, which should in turn…

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.…
