Whether recollection is a threshold or signal detection process is highly controversial, and the controversy has centered in part on the shape of receiver operating characteristics (ROCs) and z-transformed ROCs (zROCs). U-shaped zROCs observed in tests thought to rely heavily on recollection, such as source memory tests, have provided evidence in…

Two experiments explored the benefits to retention and transfer conferred by mental practice. During familiarization, participants typed 4-digit numbers and took an immediate typing test on both old and new numbers. Participants then typed old 4-digit numbers, either physically or mentally, with either a different response configuration or the…

Outlines a psychophysiological (involuntary responses to novel environmental stimuli) model of the role of orienting responses (ORs) in learning from televised lectures. Demonstrates that insertion of videographics in talking-head lectures produces ORs in television viewers. Finds that ORs enhance learning of familiar material but interfere with…

The comprehensibility, interestingness, familiarity, and memorability of concrete and abstract instructional texts were studied in 4 experiments involving 221 college students. Results indicate that concreteness (ease of imagery) is the variable overwhelmingly most related to comprehensibility and recall. Dual coding theory and schema theory are…

Studied prior knowledge as a mediator of effectiveness of the elaborative interrogation strategy for 50 male and 50 female undergraduates in a learning task. The elaborative interpretation group had significantly greater matching scores on an associative memory test for animal information than the control group only for familiar animals. (SLD)
