Week 3 - Lab Experiment Assignment Please note this is NOT research. To conduct research you would need IRB certification. This is an education task to learn about research. Imagery and Recall Experiment For our next lab project, we will be conducting an experiment on the relationship between imagery and recall. Research has shown that imagery tends to facilitate memory processes. In this experiment we will test this idea. Design This lab project will illustrate a two-factor, completely between-subjects experimental design. There are two factors: Instruction Type (Imagery versus Rehearsal) and Word Type (Concrete and Abstract). Hence this experiment is a 2 x 2 factorial. Participants Each of you will be responsible for finding and running four participants (one in each of the experimental conditions). Materials The materials for this experiment will be an informed consent form, the instructions to be read to or by participants (adapt the forms you used in Week 2's lab), and two lists of words, one consisting of concrete nouns and the other consisting of abstract nouns (see attached lists). Additionally, each participant will be provided with a response sheet. Procedure Participants are to be approached and asked if they would mind taking part in a simple experiment on memory. If the participant agrees, find a quiet place to conduct the experiment. Give the participant an informed consent form, and read the form to him or her. After reading the informed consent form, have the participant sign and date it and return it to you. Next, read to the participant the appropriate instructions, and read the list of word pairs. The list should be read at a rate of one word pair every 15 seconds in all conditions. After reading the list to the participant, go back and read each stimulus word to the participant, and have him or her write down the appropriate response word on the response sheet. Read the list of stimulus words at a rate of one every 15 seconds. Note: Each “experimenter” must run one participant in each of the experimental conditions. (So each of you will run a participant in the imagery/high-imagery words, imagery/low-imagery words, rehearsal/high-imagery words, and rehearsal/low-imagery words conditions.) Instructions: Imagery Group (Told to the participant) This experiment concerns how well you can remember words. I will read you a list of word pairs (for example: water—bird). After I have read the entire list to you, I will give you the first word from each pair (for example, water) and you will give me the word that was paired with it (for example, bird). Also, I will be giving you the first word from each pair in an order that is different from the order in which the list will be read originally. So don’t try to remember the word pairs in order. When you are trying to learn the word pairs, try to form a mental image (picture) of the two words going together. For example, if the word pair was water—bird, you might form the image of a bird sitting in a pool of water. Try to form such an image for each word pair. Are there any questions? Are you ready to begin? Instructions: Rehearsal Group (Told to participant) This experiment concerns how well you can remember words. I will read you a list of word pairs (for example: water—bird). After I have read you the entire list, I will give you the first word from each pair (for example, water) and you will give me the word that was paired with it (for example, bird). Also, I will be giving you the first word from each pair in an order that is different from the order in which the list will be read originally. So don’t try to remember the word pairs in order. When you are trying to learn the word pairs, say each word pair over and over to yourself. For example, if the word pair was water—bird, you would say “water—bird, water—bird, water—bird,” and so on, until I read you the next word pair. Rehearse each word pair in this way. Are there any questions? Are you ready to begin?

There is no need to include an introduction or abstract as we are only working on these areas at the moment. This is of course not the typical way of conducting research, but as noted earlier, this is practice, not research.
