Problem: Your choice of experimental designs makes sense, especially with your focus on cause-and-effect relationships. One way experimental research could be applied in personality psychology is by studying how situational stress impacts conscientious behavior. For example, researchers could manipulate stress levels in a controlled setting and then measure changes in task persistence using an objective personality-related scale or behavioral checklist. This would allow researchers to observe how personality-related behaviors shift under specific conditions while still maintaining control over extraneous variables. One limitation of experimental research, however, is that personality traits are often stable and deeply rooted, which makes them difficult to manipulate directly. This can sometimes reduce ecological validity, meaning behavior in a lab may not fully reflect real-life personality expression. A way researchers could overcome this is by combining experiments with pre-test personality measures, such as the Big Five Inventory, so they are measuring how traits interact with experimental conditions rather than trying to change the traits themselves. I also agree with your critique of Freud's theory, especially regarding its gender bias and heavy emphasis on sexuality. From my own perspective, Freud's ideas feel limited when applied to today's diverse social environments. I do think defense mechanisms still show up in everyday life, such as when people rationalize poor decisions. Need Assignment Help?
