Four experiments were conducted in order to contrast the levels-of-processing perspective with the transfer-appropriate-processing perspective. Experiment 1 employed a within-groups design to contrast the effects of various types of questions at different positions on subjects' recognition of sentences. The results seemed to support the transfer-appropriate-processing perspective's predictions but were confounded by the form of design. Experiment 2 examined the same questions with a between-groups design, while Experiment 3 replicated Experiment 2 with the use of a free recall posttest. The results of both Experiments 2 and 3 seemed to support the predictions of the transferappropriate-processing perspective and disconfirm the predictions of the levels-of-processing framework. Experiment 4 extended the work to subjects' memory for paragraphs. The results of Experiment 4, however, did not match the pattern observed in Experiments 1-3 and, instead, seemed to bear out the predictions of the levels-of-processing perspective. The results are discussed in terms of the influence of experimental design, choice of study materials, choice of dependent variables, and their interaction.
