Categorical clustering Essay Example for Free

Categorical clustering EssayTheories which link rec both today to the track in which the tuition is encoded are very well supported and accepted among cognitive theorists however, there is a lack of research on detail tricks to encode which may aid in rec each(prenominal) efficiency (Roy, 1967). The theories on this are widely accepted only when, in fact, are poorly supported refer adequate to(p) to their common sense value. There is a need for more research about the ways in which environment directly effects efficiency of recall.Considering all of the research done on the correlation between encoding methods and recall, it can be seen that recall is directly affected by the modality and physical characteristics of encoding (Squire, 1987). Mnemonic devices are techniques to improve retention and most involve some combination of vivid visual imagery, organization of breeding into meaningful units, and hierarchies, and association with well-learned information (Winn, 200 1).M all different memorization techniques have been designed to accommodate the unique way that every brain encodes the most effectively. Mnemonic devices have been devised to help the naturally most effective way for each individuals brain to encode information, but are geared towards visual learners. Kinetic and Auditory Learners need to modify what is organism encoded in order for it to be effectively recalled later (Expanding, 1996). These specific techniques add meaning to an otherwise meaningless make of items (Sternberg, 1999). Common mnemonic devices include bland clustering, interactive images, pegword systems, method of loci, acronyms, acrostics, and keyword systems.Henry Roediger has studied the comparative effectiveness of these mnemonic strategies and found that it was influenced by the kind of task required at the time of retrieval. He went on to suggest that when choosing a method for encoding, one should keep in mind the part of recalling the information (Stern berg, 1999).. Students are often asked to memorize large amounts of information at one time. There is a very small amount of research on the effectiveness of different mnemonic devices specifically effective for the purpose of recalling scholastic information. One method which has been theorized to fit this type of purpose of recall is categorical clustering.It has already been theorized by Weston Bousfield that the human brain automatically separates information into categories. In 1953 he tried this theory by showing that if sets of test nomenclature can be divided into categories, participants give automatically cluster their recall railroad siding by these categories. Aiding the natural inclination to categorize with mnemonic devices could greatly help memorization. Theories about this are very poorly supported. Further investigation of this specific mnemonic device is important in investigating how it affects the recall of lists of words. Knowing this would be relevant in s cholastic and other environments in which this device could be especially helpful.HypothesisIB Juniors given a list of 18 words with a list of 3 category titles will recall the items on the list more accurately than those given the list without the category titlesNull HypothesisThere is no difference in recall between IB Juniors given a list with category titles and those given the list without the titles. Methods DesignDesignThe design that will be used for this experiment is independent samples, because it meets the needs of the experiment and also minimizes defect and is effective in controlling specific internal validity concerns. This specific design controls for testing and progressive errors, most order effects, maturation, and mortality.This design, however, does not control for history. The totally unwanted subject variables in this experiment would be learning or memory deficit disorders. Drastic problems that keep a student from being able to memorize or learn new thing s effectively would negatively affect the experiment and make the results more difficult to generalize. To control for this, as a disunite of pre-screening, only juniors enrolled in the International Baccalaureate program will be used as volunteers. It can be ensured that any student which has made it that furthermost within that rigorous an academic program has no drastic disorders which effect his or her memory or ability to learn and retain information.This also controls for survival in that all IB Juniors are statistically equivalent. Diffusion of treatment in this experiment could be a problem if the subjects share words or information from the lists while trying to recall them. This could largely alter the results of the experiment and therefore the researchers will be preventing subject interaction and supervising them as they are recalling remembered words. all told subjects will be given the exact same list of words, only 1/2 will be given simple category titles. The wo rds will still be in the same order and place on the page to control for instrumentation errors.EthicsBecause subjects will be tested in front of a teacher, it will be made fully sensitive that they will be ethically treated and that in no way will this experiment alter their status in that classroom. The researchers will establish a clear and fair agreement with the research participants prior to their participation. This agreement will clarify the aim of the study, that it is completely optional, and ensure that the results will be shared with the participants after all data is collected and analyzed.The researchers will make the subjects fully aware that the study is not only optional, but that the subject can decline to participate or withdraw from the research at any time without any repercussions whatsoever. All necessary aspects of the research will be described and the volunteers will give their informed consent prior to participation. Results will remain confidential and a nonymous, but the final purpose of the study shall be revealed in a follow up session. Since all of the participants are under 18, the principal and the party who is legally creditworthy for the students while they are on campus (Mrs. Benware) will be made aware of the aim of the study and give her consent to let any volunteers participate in the study.III. Methods ParticipantsThe entire population of IB Juniors may be used in the experiment however, the statistical concepts of sampling make it unnecessary. The sample will consist of IB Juniors from Mrs. Jamisons 3rd and sixth period classes, and from various other teachers which give informed consent for the researchers to talk to their classrooms about the experiment and offer the opportunity for the students to volunteer. The participants will be a vocalization group of the entire population of IB juniors.Students which are taking psychology dont create any errors in population validity, as they havent participated in enough tra ining in psychology for their results to be altered in any way because of it. To obtain a random sample from the IB Junior class, students from random classrooms will be asked to volunteer. A random sample of 30 IB Juniors is used in the experiment. They are all 16-17 years of age and have similar academic backgrounds and capabilities, as they are all in the International Baccalaureate program.
