Throughout the semester in cognitive psychology course, we have learned how people acquire, store, transform, use and communicate information. This course was very informative and useful because we use cognitive processes in every aspects of life. Amongst the concepts we discussed in the class, I think mnemonics is one of the most important concept. As we all are students learning at the college, we have vast amount of course materials to memorize for each course. This memorizing process is especially hard when the tests are clustered in a short period of time. I found myself really struggling and stressed out for memorizing as well, but after learning about mnemonics in the class, memorizing seems somewhat easier than before. I use technique of interacting images to memorize and create a retrieval cue to better recall the concepts. I was surprised how effective this technique is, because memorizing with this technique shortened the time required dramatically. Furthermore, memorized concepts with this technique are placed in LTM, so they are still easily retrieved. Another important concept we learned is eyewitness memory. In criminal justice field, eyewitness testimony is very critical in conviction of offenders. The problem is, due to memory malleability, memory of eyewitness can be inaccurate. This can result in conviction of wrong defendant. Furthermore, according to our text book, “eyewitness testimony is likely to be believed by jurors, especially when it is offered with a high level of confidence, even when the confident witness is inaccurate.” (Galotti, 2014). Therefore, when hearing from eyewitness, misleading questions must not be asked. As we are students of criminal justice school, I believe this will be important concept to consider when we start working in the field in the future. Overall, this cognitive psychology course was very useful, and I would try to use concepts learned from the class in the future.
