Human memory Essay Example for Free

Human memory Essay The investigation into whether images aid memory recall has been fairly successful. The experimental hypothesis: participants in condition 1(words with images) would perform better than those in condition 2 (words without images), has been rejected therefore the null hypothesis: there will be no difference in condition 1 (involving grid of random words supported by images) and condition 2 (only consisting of random words) has been accepted. Only to some extent from the line graph (Condition 1 vs. Condition 2), can we say condition 1 (words with images) recalled more words than those in condition 2 (words without images) because the line for condition 1 is generally above the line for condition 2 and this fairly supports the experimental hypothesis. The results measured using central tendency and measures of dispersion moderately support the experimental hypothesis. The mean and median for condition 1 (14. 1 14. 5) was greater than of condition 2 (12. 6 13. 5) indicating that there is a better recall when words are companied by visual aid and this supports the experimental hypothesis. The range (11) illustrated that data for both conditions were equally spread out, which does not necessary support the experimental hypothesis. Standard deviation, a more reliable measure of the dispersion than range has shown data in condition 2 (3. 977715704) is slightly more spread out than in condition 1 (3. 604010112). Descriptive statistics (numerical graphical) have illustrated that condition 1 (words with images) performed better and this supports the experimental hypothesis. Not only do the numerical statistics support the hypothesis but the results are fairly pronounced, simply by looking at the line graph (graphical statistics); there is definitely a difference between both conditions although the Mann-Whitney U-test shows this to be below the level of significance. Inferential statistics, which enable us to draw clear conclusions about the likelihood of the hypothesis being true, is evidence for accepting the null hypothesis. The implication of the results measured using a non-parametric method, The Mann-Whitney U-test clearly shows that at the significance level of 0. 05, the results were very likely to have happened by chance. Though the observed value, 35 is greater than the critical value of 23 but only by 10. Comparatively, the findings of this study support previous theory and research but also are contrary to them. Bower, 1972 imagery recall experiment found that participants, who used imagery, recalled 80% of the words compared to only 45% by the non-imagers. In this investigation, participants in condition 1 (words with images) recalled 70. 5% of the words compared to 63% by the non-imagers. My investigation does support Bowers findings, since there is a difference however the differences between the two conditions is not significant. Previous research does suggest that data in STM is stored in an acoustic manner this was demonstrated by Conrad (1964). Illustrating people may not always use visual codes to remember data and this supports the null hypothesis; in addition Baddeleys (1966) study suggests that data is also stored semantically and this again illustrates that people may not always use visual codes. A possible problem with this experiment is the experimental design which lacks ecological validity and also does not account for individual differences. The study used independent groups, which meant it lacked control of participant variable and needed more participants. A matched participant design could have been used instead to deal with participant variables as participants are matched on key variables such as age and memory ability. Another problem of the study was the sample size. The study only used 20 participants, a small sample; therefore findings cannot be generalised to the rest of the population. So, a larger sample size of 50+ would be more representative and can be generalised. In addition, the investigation used opportunity sampling, which is very biased, and again it cannot be generalised. Random sampling would be the best method to select participants since it is potentially unbiased. An additional problem was the images used; some of the images were cartoon images (i. e. bible pizza) and others were actual photographs (real life images, i. e. greenhouse). This may have been a problem since real life images may possibly be easier to remember than cartoon images or vice versa. To resolve such problem, would be by using only cartoon images alone or only real life images. The recall between genders may have wider implications: on the whole men have performed better than women, when studies have shown women should perform better than men. For example; women perform better than men in tasks such as verbal learning remembering tasks, name face association, and first last name associations learning (Larrabee and Crook, 1993). Ideas for a follow up research study is the effects of gender recall and discover if there is a significant effect for the sex of a participant on the types of gender associated images recalled and to compare the effects of visual and semantic codes in depth. There is evidence to illustrate that people do remember more with the aid of visual representation and evidence to illustrate people remember more without any visual representation. This itself suggests people do remember data and information differently (individual differences), i. e. acoustically, semantically. Therefore it is important to recognize these findings as they have strong insinuations for its involvement in everyday life, for example with teaching, revision and marketing.

Jacob Lawrence :: essays research papers

Jacob Lawrence has painted figurative and narrative pictures of the black community and black history for more than 60 years in a consistent modernist style, using expressive, strong design and flat areas of color. Jacob Lawrence was a great artist. During Harlem Renaissance, he helped establish African American artists. He gave lectures at Washington University, and he enjoyed working with students of all ages. Jacob Lawrence was born in Atlantic City on September 7, 1917. His parents Jacob Armstead Lawrence and Rose Lee were part of the Great Migration of Black Americans (1916-1930). One million people left the rural South for the urban North during this period. He moved with his family for Easton, Pennsylvania. After his parents separated, he moved with his mother to Philadelphia. In 1927, his mother moved to New York and placed Lawrence and his siblings in foster homes. In 1930, Lawrence, age 13, and his brother and sister moved to Harlem to live with his mother. During Lawrence’s childhood, his family was forced to relocate many times as his parents looked for work. Steady jobs were hard to find, especially for African Americans. Racial prejudice prevented them from pursuing certain jobs or professions. Harlem was a crowded, teeming place, and the public school Lawrence attended was considered among the roughest in the area. But Harlem in the 1930s was also the center of what became known as the Harlem Renaissance. To keep her son out of trouble Rose Lawrence enrolled him in an after-school arts and crafts program at a local community center. It was taught by a young African American artist named Charles Alston. Alston liked the serious, quiet Lawrence and made sure he had lots of materials for his efforts. He found that drawing geometric designs in bright colors satisfied him greatly. He soon moved on to elaborate patterns and developed his own method of painting in which particular shapes were rendered in corresponding colors, one at a time. Lawrence continued in this mode through much of his career. The notable consistency of color is apparent in the artist’s later series of story panels. Lawrence got many of his ideas from the books and magazines he found at the center where the classes were held. Lawrence had Alston show him how to mix paper-mache, and he went on to create many colorful, life-size masks. He also used cardboard boxes to fashion three-sided scenes, depicting locales in Harlem- stores, barbershops, houses and newsstands.

Deterioration of the English Language

Word Count: 1,237 Denise Moreno Professor Carlene Coury English 120 13 April 2013 Deterioration of the English Language The English language seems to be deteriorating more and more each day. So many examples can be given to justify this observation. Three different writers have pointed out some examples of the butchering of the language. Martha Brokenbrough states that the constant use of instant messaging jargon and internetism can certainly be a good way to reshape the way we communicate. At the same time she writes it can also affect the way we communicate properly and professionally.Author, George Orwell, speaks about how we have developed words in the English language to disguise the true meaning for political causes. Orwell points out that we mask what we truly want to say, and at the same time, we confuse the reader by not making sense of what we write. Speechwriter, Clark Whelton, pointed out that vagueness is a growing problem in our mother language; therefore, college stude nts don’t know how to stop being vague while trying to communicate. Even though all three writers make different points about English decaying as a language, they all concur in the cause of this problem, laziness.Martha Brokenbrough states â€Å"So the key with Internetisms is to know when it's okay to use them, when it's not okay, and when not using them will make you look clueless† (149). Brokenbrough emphasizes that using instant messaging lingo is not bad, and it is appropriate in specific time and places, however, not knowing where and when to use this lingo, can cause confusion and make you look foolish. LOL is a very common phrase to hear nowadays, but when one goes to a job interview and can’t carry a conversation without using any of these abbreviations, it is not only unacceptable but disrespectful.The shortcuts we use may be making us look lazy and dumb when used at a courtroom or a doctor’s office as examples. LMAO seems impolite and childish when used at these places. This type of jargon is, however, necessary when texting and chatting in the world today to be considered hip and normal. One thing that is important to remember is to know when to use the instant messaging lingo and when to not use it as the author claims. More importantly, she explains that it does not take that much longer to use the correct words when needed so that others do not think one is dumb.Knowing when to use all these internetisms can save us embarrassment and make us seem cool if used correctly. â€Å"Most people who bother with the matter at all would admit that the English language is in a bad way, but it is generally assumed that we cannot by conscious action do anything about it†(446). In this quote, George Orwell states that it is not that we don’t know how to properly communicate our ideas, but we choose to do nothing about it to correct it. There are a lot of useless words that political writers tend to use when wanting to be unclear but with the intention of making writings seem as clear as water.Orwell mentions some types of these unnecessary words: dying metaphors, verbal false limbs, pretentious diction, and meaningless words. Dying metaphors â€Å"are merely used because they save people the trouble of inventing phrases for themselves†(448). The author is explaining that sometimes in writing there are a lot of recycled expressions that we all use generally as opposed to looking for our own and being original. What verbal false limbs do is that they â€Å"save the trouble of picking out appropriate verbs and nouns, and at the same time pad each sentence with extra syllables which give it an appearance of symmetry†(449).This quote is referring to the words we tend to use as fillers and again are meaningless to use in a sentence. Verbal false limbs are words that the writer can do without in order to make sense. Pretentious diction are words that are â€Å"used to dress up simple sta tements and give an air of scientific impartiality to biased judgments†(449). Words like â€Å"phenomenon† and â€Å"effective† get used to pursue the writer to believe the biased thoughts you may want to get across.Finally, meaningless words are â€Å"strictly meaningless in the sense that they not only do not point to any discoverable object, but are hardly ever expected to do so by the reader†(450). Using these kind of words is only good to persuade the reader into believing things that aren’t meant by the writer. All of these words are examples of bad choices while writing and once again an example of laziness. Orwell emphasizes that writers make the mistake of using all these words to express themselves, but in reality they just end up not being able to communicate what it was they really wanted to say. Playbacks and self-quoting (He was like, â€Å"Where are you going? † and I was like, â€Å"I'm going to work†) are the most dura ble symptoms of vagueness, and may find permanent homes in 21st century English†(Whelton, par. 14). This particular quote by the speech writer, Clark Whelton, highlights the most common way English has become vague. â€Å"Whoa, that is so wow† â€Å"well, like yeah† and â€Å"I mean like, you know† are examples of vague talking and the loss of proper English. Whelton points out that younger people, even having graduated from college, lack a sense of professionalism and good communicative verbal skills.He states that it is so common to hear people express themselves with â€Å"self-quoting, playbacks of past conversations, ‘up talking’ (ending declarative sentences with an interrogative rise), and run-on sentences†(Whelton, par. 2). The examples given are comparable with ways a child would communicate. After using these bad habits of communication over and over again, there is no doubt that knowing how to properly carry on a conversation disappears off the permanent memory. The author implies that if the problem of vagueness had been corrected at an early age, vagueness itself would have been a lot more contained than it is now.Along with Brockenbrough and Orwell, Whelton has insinuated that writers today have lack of thought for themselves, also known as laziness. Using abbreviations related to instant messaging, words that have no exact meaning or used as fillers, or simple vagueness such as â€Å"like†, is wrong when wanting to communicate in formal or professional way. Not only would using these types of shortcuts make one look dumb but also lazy. Possessing the correct skills to communicate verbally or in written form is as important as knowing how to match a clothes outfit.One is under the belief that using internetisms is going to save time, but unfortunately, that is only a myth. The truth is using shortcuts saves only seconds that can make the difference in appearing dumb, lazy, or intelligent. To s ound distinguished by using exotic or meaningless words, one might use as padding for our confusing writing, can cause one to appear dumb and lazy as well. Being vague does not help anyone in trying to clearly communicate what they truly want to say; it only makes people look childish and sluggish.All in all, the three writers agree that no one should opt for easy time saving abbreviations, fake fancy words, or vagueness that plagues us, to communicate properly and not be thought of being a dumb, lazy, childish person.
