The present study had two aims. First, we set out to evaluate the structure of processing speed in children by comparing five alternative models: two conceptual models (a unitary model, a complexity model) and three methodological models (a stimulus material model, an output response model, and a timing modality model). Second, we then used the…

The spread of encoding concept was tested visually by having subjects view pictures which varied in contour completeness. The hypothesis was supported that as contour completeness decreased, the amount of perceptual analysis and memory performance would increase. (Author/MH)

Reviews study of undergraduates which evaluated the effects that variations in depth of information processing have on students' memory systems in terms of their ability to acquire and retrieve information related to different types of instructional objectives. The effect of visual versus verbal testing of visualized instruction is also examined.…
