In your report, write a brief introduction of the experiment explaining the levels-of-processing framework. Next, in the Methods section, describe the process that you followed to complete the experiment. Make sure to include enough information so that others can also perform the same experiment successfully.

Finally, describe the experimental results in all the three conditions. In addition, identify the condition where you performed the best and the worst. Provide a rationale explaining why the results differed in all the three conditions. Summarize your report, including answers to the following questions:

  • Were the results in accordance with your expectations? Provide a rationale to support your answer.
  • Did anything about the experiment surprise you? If yes, what?
  • What factors would influence the results of the levels-of-processing experiment?

    Levels of Processing

    What methods did we employ in this experiment?

    There were two parts to this experiment. In Phase I, you were given a word and a judgment task. There were three types of judgments. The first type of judgment (letters) was to decide if the word had a particular pattern of consonants and vowels. The second type of judgment (rhyme) was to decide if two words rhymed. The third type of judgment (synonym) was to decide if one word was a synonym of another. In Phase II, you saw a series of words, half of which had been shown in Phase I. For each word, you were asked to indicate if it had been shown in Phase I. The independent variable in this experiment was the level of processing induced by the judgment task: shallow (the letters task), medium (the rhyme task), and deep (the semantic task). The dependent variable was the proportion of times the word was correctly recognized as being in Phase I.

    What do we predict participants will do? Why?

    People should correctly recognize more words with the deep processing task and fewer words with the shallow processing task. The reason is that on a standard word recognition task, most people use semantic information as a cue to retrieval, and the type of processing most appropriate for a semantically-driven task is also semantic processing at test.

    How robust is this effect? Are there limits to this effect?

    The effect is quite robust and is not limited to recognition tests. However, the effect can be altered if the test is changed. For example, if the test asked you whether there was a word on the list that rhymed with a particular test item, you would do better for those items you made a rhyme judgment on in Phase I than the items that you processed deeply.

    Data summary for experiment Levels of Processing.

    Accuracy on the recognition test as a function of the study condition in Phase I. The expected result is that recognition accuracy will show a levels of processing effect, with best performance for the deep task (synonyms) and worst performance for the shallow task (letters). Lure recognition is correct classification of an item not presented in Phase I.

    Data summary

    Condition/Task Proportion Correct
    Letter Recognition 0.55
    Rhyme Recognition 0.6
    Synonym Recognition 0.9
    Lure Recognition 0.76666665

    Trial-by-trial data

    The Condition column describes the judgment task during Phase I. Here ‘lure’ means the item was not shown during Phase I. The study response and study accuracy columns indicate the response and accuracy of the response during Phase I. The recognition response and recognition accuracy columns correspond to the responses during the Phase II word recognition. Lab Report Paper: Levels-Of-Processing Experiment
