Levels of Processing and memory The aim of the experiment is to investigate (a) whether level of processing (IV1) affects memory for words‚ (b) whether the intention to learn (IV2) has an effect upon memory and whether an effect of level of processing on memory for words is dependent upon intentionality of learning (IV1xIV2)‚ i.e. Is there an interaction effect? Levels of Processing is an influential theory of memory proposed by Craik and Lockhart (1972) which rejected the idea of the dual store

standardized tests? We designed an experiment which would put an answer to this question. The experiment tests the spectrum of standardized test scores of those who ate breakfast versus the scores of those who ate nothing. This experiment would be a single blind study because the scientists would not be biased therefore they would have no reason to alter the test results; it is a purely research type experiment. There would be two groups involved in the experiment- the experimental group‚ which would
