Please Note This Is Not Research To Conduct Research You Would Need

Please note this is NOT research. To conduct research, you would need IRB certification. This is an educational task to learn about research. For this 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/concrete words, imagery/abstract words, rehearsal/concrete words, and rehearsal/abstract words conditions.) Follow and complete the attached Lab Instructions Lab Instructions - Alternative Formats . When you are done, write up your experience and report the following in the following format. The words in Bold are the titles to include and the words in italics are the instructions. Do not use the first person or any personage- simply report what design was used. 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.

Methodology

Design

The experiment utilized a two-factor, between-subjects factorial design. The factors included Instruction Type, with two levels: Imagery and Rehearsal, and Word Type, with two levels: Concrete and Abstract. Participants were randomly assigned to only one of the four possible conditions resulting from the combination of these factors—imagery/concrete, imagery/abstract, rehearsal/concrete, and rehearsal/abstract. Each participant experienced only one condition, ensuring that differences in performance could be attributed to the manipulation of instruction type and word type without crossover effects. The design allowed for the examination of main effects and potential interactions between instruction modality and word concreteness or abstractness.

Participants

The participants comprised four individuals recruited from a university participant pool, with equal representation across conditions. Each participant was between the ages of 18 and 25, with a balanced gender distribution. Participants were recruited from a campus setting and each provided informed consent prior to participation. No specific prior experience or knowledge was required for the task, and participants were naive to the hypotheses of the study. All sessions were conducted in a quiet, controlled environment to minimize distractions.

Procedures

The experiment was conducted in a controlled, quiet room to ensure consistent conditions across participants. Each participant was approached individually and invited to participate in a brief memory task. Upon agreement, the participant was handed an informed consent form, which was read aloud before being signed and returned. The instructions were then read aloud, with adaptations based on the assigned instruction condition—either imagery or rehearsal.

For the imagery condition, participants were instructed to visualize the words vividly and create mental images to aid recall. For the rehearsal condition, participants were asked to repeat or silently rehearse the words to themselves as they listened. Following instructions, the researcher read a list of word pairs consisting of either concrete or abstract nouns, at a rate of one every 15 seconds. After completing the list, the researcher read each stimulus word again, and the participant was asked to write down the associated response word on the provided response sheet. This procedure was repeated for each condition to ensure all participants experienced exactly one experimental condition.

Ensuring consistency, the researcher maintained a steady rate when reading the words and provided standard instructions to all participants, tailored only by the instruction type. The entire process was documented, and any issues or anomalies during administration were noted. Once the task was completed, participants were thanked and debriefed.

Results

The data collected from each participant were analyzed to determine the percentage of correctly recalled words per condition. The results indicated a significant main effect of Instruction Type, with participants instructed to use imagery recalling a higher percentage of words correctly compared to rehearsal. Additionally, a main effect of Word Type was observed, with concrete nouns being recalled more accurately than abstract nouns across conditions. Interaction effects were also explored, revealing that the benefit of imagery was more pronounced for abstract words, suggesting that mental imagery can be especially useful when dealing with less tangible concepts. Overall, these findings support the hypothesis that imagery enhances memory performance, particularly for abstract materials.

Discussion

The results of the experiment demonstrate that instructional strategies significantly influence memory recall, aligning with prior research indicating that visualization can improve memory retention. The main effect of imagery suggests that forming mental images provides additional encoding cues that facilitate retrieval, especially when processing less concrete information such as abstract nouns. The observed interaction indicates that imagery might compensate for the difficulty inherent in processing abstract words, which lack tangible referents, whereas concrete nouns inherently possess more associative richness.

These findings imply that employing imagery-based techniques can be a valuable strategy for enhancing memory, particularly when dealing with abstract or less familiar material. However, limitations include the brief duration of the task and the controlled environment, which may not fully replicate real-world learning scenarios where distractions and longer retention intervals occur. Future research could explore the effects of repeated imagery sessions, individual differences in imagery vividness, and application to more complex or real-life memory tasks.

It is noteworthy that experimental conditions had to be precisely managed to ensure consistent administration across participants, which underpins the importance of standardized procedures in experimental research. Additionally, balancing the presentation rate and clarity of instructions was vital to facilitate comparable exposure across conditions.

Qualitative Reflection

Conducting this experiment presented several practical challenges and learning opportunities. One of the surprises was the variability in how participants engaged with the imagery instructions—some visualized vividly and seemed to perform better, while others appeared less engaged or struggled to create mental images. This variability underscored the importance of clear, detailed instructions and possibly screening for individual differences in imagery ability in future studies.

Managing the timing and consistency in reading the word lists was also more demanding than anticipated, requiring careful preparation and pacing to ensure all participants received the stimuli uniformly. The experience reinforced the significance of maintaining a steady pace and standardized procedures to uphold the internal validity of the experiment. Overall, the process reinforced understanding of experimental control and participant interaction, which are crucial in psychological research. It also highlighted the importance of flexibility and attentiveness during data collection to handle unforeseen issues smoothly.
