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.

Comparative Elegies~Similar or Different? :: essays research papers

An elegy is a poem of lament, usually formal and sustained, over the death of a particular person; also, a meditative poem in plaintive or sorrowful mood. Through an elegy authors are able to convey their deepest remorse and grief through the eloquent use of the English language. Three elegies in which show the possible interpretations and moral convictions of death are â€Å"Elegy for Jane†, â€Å"Elegy Written in a Country Churchyard†, and â€Å"A Satirical Elegy†. Jane's unfortunate death in an equestrian accident prompted one of her professors, the poet Theodore Roethke, to write a moving poem, "Elegy for Jane," recalling his young student and his feelings of grief at her loss. It is very interesting that Jane's death is not the subject of the poem; rather, her death presents an occasion for calling up a certain emotional state in which Roethke's feelings of grief and pity transcend the occasion. This spiritual epitaph is laced with imagery; painting an extremely vivid picture given the details about her image. Roethke associates the deceased with elemental aspects of nature--the plant tendrils, the pickerel smile, trembling twigs, whispers turning into kissing etc. His lines create an amazingly tranquil atmosphere. Her voice is described as if it were perfectly toned; touching everyone that crosses her path of wind. Roethke compares Jane to a wren, a sparrow, a pigeon—all birds which draw forth an emotion. Birds naturally symbolize peace, freedom, and love. The wren represents joyful times, the high moments in Jane’s life; the sparrow however usually represents those who feel they are not worth anything; and pigeons I personally think are trite birds. â€Å"Elegy for Jane† is not the only elegy which incorporates nature into its meaningful lines. â€Å"An Elegy Written in a Country Churchyard† by Thomas Gray is a similar elegy to â€Å"Elegy for Jane† in that it incorporates mother nature and the animal which is most unique to her—the bird: â€Å"The breezy call of incense-breathing morn, The swallow twittering from the straw-built shed, The cock's shrill clarion, or the echoing horn, No more shall rouse them from their lowly bed.† Not only are these elegies similar because of their richness of the language and comparative nature with the outside world but also in that it mourns the death not of great or famous people, but of common men. The speaker of this poem sees a country churchyard at sunset, which impels him to meditate on the essence of human mortality.

Sonnet Writing

In Judith Rodriguez piece In-flight note, the author illustrates a sonnet within a sonnet that tells the story of a boy writing a love letter on a plane. As she watches over his shoulder, the author acts in an invasive yet inquisitive manner as she intrudes on the love that the boy is trying to express. He seems reluctant to write and torn between his decision to leave and his love for his teenage beau.As she watches him write, â€Å"It’s naive to think we could be just good friends,† she appears to be bitter, frustrated and jaded about love in general. As if a friendship has been loved and lost or a past lover has walked from her in the same way the boy has left. With the use of her language and ideas that she is expressing, it is as though ridiculing the boy for falling in love. As she ends the piece with, â€Å"Pages and pages. And so the whole world ends,† she demonstrates a vivid and dramatic line that reflects a young and teenage love.It shows that the auth or believes that this love is not over and it will continue to play out in life or in thoughts of both the teenagers, for years to come. The striking thing about this sonnet is that although it has a sour feel about it, it is like the author is well aware of heartbreak herself and in criticizing the boy she is in fact criticizing herself from afar. Although the sonnet does not openly reflect a love poem, it still paints a picture of the harsh, cruel heartbreak and pain that it can cause.

Outline and Evaluate Research Into Types of Attachment Essay

Outline and evaluate research into types of attachment. Ainsworth conducted a study to observe types of attachment behaviours with occur between a mother and a child. She used observation to witness these behaviours. By placing the child in a set up play room with one way glass allowed natural behaviour to be observed without interference from the psychologist. Ainsworth used several situations including a mother a child and a stranger. Firstly the mother and the child entered the room, the child was free to explore whilst the mother sat on a chair and read a magazine, a stranger enters and sits next to the mother, they engage in conversation. The mother leaves, and the child is left alone with the stranger who shall comfort and play with the child. The mother then re-enters, and the stranger leaves. The mother then also leaves, and the child is left alone. The stranger re-enters and the mother re-enter shortly after, and then the stranger leaves again. A problem with the study is it lacks ecological validity; the child may have reacted differently in settings they were familiar with, an example being their own home. The child could already be anxious due to strange surroundings and unusual behaviour by the mother, therefore leading to higher chances of stranger anxiety and other stressful behaviour. Ainsworth in her study found three types of behaviour, these were Type A – Insecure avoidant, Type B – secure and Type C – Insecure resistant. Type A showed the child being upset when mother left the room, but did not seek comfort when she returned and showed little stranger anxiety. Whereas in Type B the child used the mother as a safe base and was free to explore when she was around, showed distress when she left but still seeked comfort when she returned and showed stranger anxiety. Differently in Type C, the child’s behaviour alternated between wanting comfort and wanting space, and appeared to be angry. The psychologist did not follow all the ethical guidelines in this experiment, the child was put under great stress with the mother leaving and returning, and also in the presence of a stranger, upset the child and made it upset. The psychologist must control this by lowering the stressful situations for the child and finding alternatives. Although they did get full consent as mother of the child took part within the study, which made the situation less stressful and made the child more comfortable. Ainsworth study also lacks the explanation of relationships between fathers and siblings, the child may act differently with different people and this lacks validity as it is not a measure of general attachment.

Article Critique on Diversity Essays

Article Critique on Diversity Essays Article Critique on Diversity Essay Article Critique on Diversity Essay Methods Using other published articles as reference, a comparison of the public policies in Japan, Switzerland, France, Germany, United Kingdom, and Canada were compared to ) explain diversity among countries and the policies for managing ageing work forces, 2) to show applicable remedies to convince firms to keep older workers. Evidence of Thesis Support The author offered a comprehensive approach to the trends and illustrated the connection between the company practices and these trends, even if not always equally thorough. Despite the strength in making those comparisons, the author did not reach his full potential, while the diversity was presented In the studies, the results were loss because the articles were cited In one mall paragraph so there was o connection between and country and where the information was derived. The supporting evidence was confusing and ambiguous, in an overview of employment/ unemployment policies towards older workers the similarities and differences between countries needed to be clearly identified. The remedies were equally limited, an adjustment to the procedures for assigning employees to Jobs and motivating workers was one of the remedies, however those procedures were not illustrate In the article. Further, the public policy that the author advocates as having little success has not been identified. To get insight and gain a better understanding one would have to read all the individual articles on which this one was formed Contribution to the Literature Contributions which correspond to the alma of the article are more Interesting and thorough.. Gill Gorton, 2001) In the Dynamics of Managing Diversity: A Critical Approach explains the clear differences between encouraging the exit of older workers through retirement, public policies and the legislative protection against discrimination. On a European-wide comparison, specific age-related legislation is emitted In France, workers aged fifty to fifty-four who are made redundant are excluded from the state pension, and the em ployer is forces to bare the cost (pig. 44). Kiloton advocates for stronger public policy In older workers to encourage employers to Turner develop tenet own strategies. ) In Social Protection versus Economic Flexibility: Is There a Trade-off makes similar arguments for looking at the legislative policy. Blank states Japan has a seniority-earning profile which creates an incentive for firms to dismiss their older workers, however, unlike the United States older workers are less likely to be dismissed. Sweden uses a seniority rule for dismissal, older workers are explicitly protected by legislation, workers over eager 45 must be given six months notice of dismissal, and employers must try to find other Jobs for those who have lost the ability to perform usual Jobs (pig 206). Recommendations The article argues the dynamics of policies in countries determine retirement or retention at age 55; to strength the article a more in depth analysis of the organizational cultures would be included. In addition, statistics on the percentage f people over age 55 in those countries to show a comparison of the employment and unemployment rates of older workers. A more in depth explanation on why there are trends would be to include what the demand is for Jobs versus the supply of human capital, whether the labor skills in these countries can or cannot meet the demand. Key questions to answer in the article are do firms fire older workers when there is a downturn in business? Social programs and how it determines the breakdown of the employment/population response, do firms require more mature errors?

Team Building without Time Wasting Essay Example | Topics and Well Written Essays - 2000 words

Team Building without Time Wasting - Essay Example Arising from a variety of reasons, team members are not able to travel expeditiously to distant locations for organizational meetings or participate in distant projects. The reasons of hurdles generated in the process pertaining to inaccessibility to crucial and critical information sources, emotional and financial costs associated traveling to remote locations for business purposes, time lost during traveling or recovering from traveling. This is the reason why organizations working in partnerships are increasingly resorting to the development of virtual teams to work collectively across borders of nations without having to travel. In this way, much of the time and money lost due to traveling can be saved and work can be proceeded with at a fast pace because of online ease of communication. Organizational culture refers to the norms and regulations regarding information flow shared leadership and cross-border collaboration between organizations. Organizational norms and values which emphasize on collaboration, respect and encourage people working across cultures are seen to demonstrate successful teamwork and team building. Such organizations keep information sharing and criticisms constructive (Davidson, et al., 2002, p.102). The organizational culture sets the basic standards with regards to how it must operate and sets certain standards with regards to the ways in which team members can behave while working together. This can be particularly true for the technologically advanced, non-hierarchical and adaptive organizations which can be very effective in nurturing a team building and team working culture in the organization. The success of the virtual teams in organizations depends largely on the way organizations impede or fosters trust between itself and the partner organization. It is crucial to treat the partner organization as equal and eligible to have access to all its information.
