Memory for Designs Test

Memory for Designs Test Introduction The examination of the functioning of the memory of an individual cannot be limited to only one memory test, and as a result, there are a variety of assessments that target the various features of the memory. Memory test procedures take into consideration various attributes including features of the test instrument such as legitimacy and consistency of results.Advertising We will write a custom research paper sample on Memory for Designs Test specifically for you for only $16.05 $11/page Learn More Tests should ideally sample a variety of non-related features of the memory to make sure that particular inadequacies in the memory can be identified. In addition to this, aspects of recall and recognition should be tested, as a way to monitor memory processes in relation to memory indicators (Dustman Beck, 1980). It has been observed that most of the memory encounters are incidental as opposed to premeditated. In view of this, one of the tests admin istered should be unexpected, to prevent rehearsal. Some tests are administered through visual aspects, ignoring auditory-verbal presentation modes as well as motor-retrieval response modes. To make certain that the results obtained are well- founded, the person administering the tests should sample an appropriately broad range of test behaviors. Computerized testing has a number of drawbacks including time consuming and high cost of setting up the system (Dustman Beck, 1980). Memory for designs test The Memory for designs test was designed by Graham and Kendall, in 1946. The test examines visual recall of an individual based on brain damage versus functional disorder versus normality. It is a popular test for the examination of brain damage in children and adults. The scoring system allows the accumulation of normative data (Graham Kendall, 1947). Administration of the test The test is administered by presenting a series of fifteen geometric designs of increasing difficulty on in dividual cards. The cards are nine by twelve inch pieces of paper, with all designs drawn on the same piece of paper. Each design is presented to the individual alone, in a prearranged sequence. The subject is supposed to view the design for five seconds before it is removed from his view. The tests duration is about five to ten minutes (Erickson Scott, 1977). Development of the test The memory test was intended to draw the line and distinguish between individuals who are organically impaired and those who are functionally impaired. The inability to reproduce geometric designs from immediate memory is related to organic impairment.Advertising Looking for research paper on psychology? Let's see if we can help you!

The final set of tests included those designs that were found to be easiest to score as we ll as discriminate best between groups. The test has since been used with all age groups for both clinical and research purposes (Erickson Scott, 1977). Sample According to Graham and Kendell (1960), there were a variety of samples such as the original validation group and a cross-validation group. In the original group, there were 70 brain-disorder patients with mixed diagnoses and 70 controls. They were all matched for age, education and occupational status. The original group included an equal number of males and females, as well as African Americans. The age bracket of the subjects was 9 to 69 years, with an average age of 42 years. The average educational level was eighth grade. The latter group comprised 33 brain-disordered patients and 168 control patients. There were three times as many men as women, with an average age of 28 years for the controls and 37 years for the brain-disordered subjects. Both groups had an average education of ninth grade (Peterson Mangen, 1981). S coring, scale norms and distribution According to the criteria provided by Graham and Kendall (1960), each reproduction has a score of 0-3, whereby the highest score signifies the worst performance. There was no penalty due to incomplete or forgotten designs. This is because the variables did not distinguish brain damaged subjects from control subjects. Reliability tests According to Graham and Kendell (1960), the split half reliability was .92 for 140 brain-damaged patients. Test-retest correlations conducted in the same session or within a 24 hour period for other groups ranged between .81 and .90. The clinical usefulness of the test is based on the adequacy of its standardization for various age groups as well as a variety of non-brained-damaged, psychiatric individuals. The reliability of the scoring is suitable based on data provided in the test manual. In addition to this, new studies on the reliability have found it satisfactory. Qualitative scores are possible based on a mea sure of the tendency to rotate the designs, whereby the error can be reliably calculated (Graham Kendall, 1947). The age standardization for normal adults is adequate though the normative data that is available for different functional psychiatric groups is not. It has been observed that some functional psychiatric disorders produce lower scores on the MFD test, though there are no age norms for representative populations of functional psychiatric disorders.Advertising We will write a custom research paper sample on Memory for Designs Test specifically for you for only $16.05 $11/page Learn More This poses a challenge in the omission of the presence of a specific functional psychiatric disorder as a substitute explanation of a poor score based on the presently available norms, unless the alternative was eliminated on a different basis (Peterson Mangen, 1981). Validity tests An analysis of a large number of tests conducted on a sample of a hundred people t o diagnose brain damage showed a +.597 for the memory for designs test on the first factor. This was interpreted as perceptual organization or the ability to integrate the relevant aspects of the perceptual field. Based on the perceptual organization factor, a memory aspect was observed from the tests, proving that perceptual organization was able to facilitate performance when memory was involved (Peterson Mangen, 1981). The MFD test has been proven to always differentiate between groups of patients known without any doubt to have brain damage, as well as to match groups of normal people and psychiatric patients thought not to be brain damaged. According to the definition of brain damage, that it is any amount of cell death in the cerebral cortex irrespective of the cause, every person aged above 30 years would be brain damaged. Some forms of birth trauma, childhood injuries and anoxia cause cell death in many normal children, though the damage is insignificant since it does not r esult in impairment (Richie Butler, 1964). Predictive validity According to data presented in the Graham and Kendall ( 1960) test manual, a significant mean score difference between a group of brain-damaged and normal individuals, at the 0.01 level. This indicated an overlap in the scores of the non-brain-damaged and brain damaged groups that caused difficulties in coming up with a decision on the performance of borderline people. An example was the cut-off point whereby 4% of the controls were diagnosed as having brain damage. Out of these, half of the brain-damaged subjects in one group and 48% in another group were designated with brain damage. The other cut-off point made for varied combinations of correct identifications, errors and false positives (Richie Butler, 1964). Convergent validity According to Warren and Mangen, the memory for designs test correlated .85 and .81 with scores on the Bender Gestalt test.Advertising Looking for research paper on psychology? Let's see if we can help you! Get your first paper with 15% OFF Learn More Usability on older populations The test is timed. In addition to this, manual coordination is required. The involvement of these factors implies that the aged may be handicapped. Sensitivity to age difference According to Peterson and Mangen, there was a significant correlation between performance and age, of 0.27. This implied that an increase in age of the subject corresponded to poorer performance of the subject. There was also a correlation of -.31 of the MFD test scores with intelligence. Assessment by the vocabulary score on the Wechsler-Bellevue showed a significant multiple correlation of .44 with age and intelligence (Peterson Mangen, 1981). According to a study conducted on psychiatric patients aged above 60 years, 36 brain damaged and 36 controls, there was a considerable difference in the mean scores, which was not as high as that between, brain-damaged and standardization groups of younger ages. The mean scores were 8.44 and 13.89, while the SD was 6.33 and 5.81 for th e controls and brain-damaged group respectively. There was a big difference between this age group and all younger control groups, though the difference with the scores of adults between the ages of 20 and 60 did not vary much. The confounding factor was that the controls over 60 years had a decline in vocabulary scores that was the same as that of the brain-damaged groups, which yielded negative results for the younger ages. This signified that the use of psychiatric controls for the older age-group would be unsuitable (Dustman Beck, 1980). According to another study conducted for subjects between the age of 20 and 80, with 50 men and 40 men in each constituent decade, the performance of older age groups on the MFD was observed to be stable until the age of fifty, after which there was a fast decline and increased variability in subjects’ performances (Peterson Mangen, 1981). Conclusion The test’s reliability and validity are good, since it discriminates in a ration al manner between groups with brain damage and normal groups. The test has limitations when conducted on aged subjects since it requires manual coordination. In addition to this, it is timed and the performance correlates with age and intelligence. Unusual scores signify damage in a specific cortical area, which in turn signifies a formerly particular dysfunction. It could be translated to mean a shortened life expectancy, though the MFD is hardly translated to imply such occurrences. Studies have shown an insignificant correlation between MFD score and a rating of severity of brain damage according to certain assessment criteria such as EFG (Peterson Mangen, 1981). Other studies have also shown a wide range of MFD scores when the test is administered to a psychiatric group whose brain damage status is uncertain, resulting in no conclusions from the features shown by the group. One practical consequence of an abnormal MFD score which has been demonstrated is that the patient is lik ely also to have abnormal scores on several other tests of brain damage such as the Bender Gestalt Test, and the Benton Visual Retention Test. An abnormal MFD score might enable the clinical psychologist to identify a previously unknown pattern of associated psychological abnormalities which might have implications for the adjustment of the patient. Another useful implication of an abnormal MFD score among children is that one might anticipate difficulties in learning to read, as suggested by several studies (Erickson Scott, 1977).

Harvey Industries Case Study Example | Topics and Well Written Essays - 750 words

Harvey Industries - Case Study Example As regards contemporary global business practice, Stevenson (2010, p. 613) identifies the importance of due diligence in ensuring sustainable supply chain management. It is, therefore advised that the company employ key components of due diligence which would make the company function in line with other global competitors. Indeed, if the company wants to succeed, it must ensure that there is due diligence in all supply models and that existing competitors are made the target of competition. One of the best practices that the company can put in place to bring about due diligence is to â€Å"ensure that they are aware of, and can describe, the risk of violations taking place, and their potential harm† (The Danish Council for Corporate Social Responsibility, 2010). Secondly, it is recommended that risk assessment that leads to the identification of the sphere of influence be embarked upon. According to Stevenson (2010), companies that consider the sphere of influence ensure that there is the appropriate recognition of the company’s responsibility and attempts regarding supply chain management. Once such recognition is in place, the company obtains a better understanding of its scope of demands and acts to reach a stipulated level of demand. Finally, structural adjustment at the human resource level is highly recommended. There is an adage that new wine is not stored in an old wine sack. Essentially, there should be some bold managerial decision such as the decision to change suppliers and other stakeholders. who are instrumental in the supply chain management but whose actions have led to the current crisis experienced by the company. Recommendations for Inventory Management Inventory management will remain a very crucial aspect of the company if it wants to rise from its present financial distress and get back on the track of success. This is because inventory management will remain the single gateway for the company to ensure responsibility and

Experimental in IR - Research Paper Example Reflecting the usefulness and the limitations of experiments alongside evaluating the text of Hudson and Butler, the research question of this paper is â€Å"How can experiment as a research methodology fulfill the aims of social scientific investigation†. The rest of this paper will forge an analysis by reflecting on different issues in political research to answer the question. The question is significant in the field of international relations because it will not only open the discussion of whether experiments could be used as a mainstream method in international studies but will also help us look into the areas of research which has been insufficiently investigated.One of the main aims of a social scientific inquiry is to produce knowledge and objective facts that will not only help to solve real-world problems but will also produce other similar questions that will spearhead the further political investigation. Similarly, the work of a social scientific inquiry is to also â€Å"further the goals of a scientific literature†. The subfields of international relations are constantly growing in areas like Cognitive Psychology, Anthropology, Socio-biology and comparative politics. The fact that international relations are constantly growing in an interdisciplinary manner provides the ground to use the experimental method to fulfill the ambitions of this issue area.The rigorous technique of researching with experiments will not only provide a bridge but will also connect the knowledge gained from the research.

Wavelength of 10 or Higher and 11 down. Gamma Rays are produced in labs   Ã‚  Ã‚  Ã‚  Ã‚  Gamma Rays are Waves on the electromagnetic Spectrum that have a Wavelength of 10 or Higher and 11 down. Gamma Rays are produced in labs through the process of nuclear collision and also through the artificial Radioactivity that accompanies these interactions. The high energy nuclei needed for the collisions are accelerated by such devices such as the Cyclotron and synchrotron.   Ã‚  Ã‚  Ã‚  Ã‚  There are also many uses for Gamma rays in Medicine. Gamma Rays are used in medicine to kill and treat certain types of cancers and tumors. Gamma rays passing through the tissue of the body produce ionization in the tissue. Gamma rays can harm the cells in our body. The rays can also detect brain and Cardiovascular Abnormalities. These are some of the many uses of Gamma Rays in Medicine.   Ã‚  Ã‚  Ã‚  Ã‚  Gamma Rays are also Used a great deal in modern day industries. Gamma Rays can be used to examine metallic castings or welds in oil pipelines for weak points. The rays pass through the metal and darken a photographic film at places opposite weak points. In industry, Gamma rays are also used for detecting internal defects in metal castings and in welded structures. Gamma rays are used to kill pesticides and bugs in food. Gamma rays are also used in nuclear reactors and atomic bombs.   Ã‚  Ã‚  Ã‚  Ã‚  Gamma rays are often used in the food industry. The radioisotopes preserve foods. Although the rays never come in contact with the food, Beta radiation kills various organisms such as bacteria, yeast, and insects. Gamma rays are sometimes used in science. They are used to detect Beryllium. They also played a very important role in the development of the atomic bomb.   Ã‚  Ã‚  Ã‚  Ã‚  Gamma Rays can be very dangerous to use or be in contact with. Gamma rays bombard our bodies constantly. They come from the naturally radioactive materials in rocks and soil. We take some of these materials into our bodies from the air we breath and the water we drink. Gamma rays passing through our bodies produce ionization in the tissue. High levels of gamma Radiation can produce ionization of the tissue and cause skin cancer.   Ã‚  Ã‚  Ã‚  Ã‚  There are many ways in which we can protect ourselves from these harmful affects Protection from gamma rays can be obtained Using a sheet of iron that is a 1/2 inch thick. This kind of shielding will block only 50% of 1 million electron volts of Gamma rays. We can also protect ourselves from gamma rays with 4 inches of water. Lead provides the most protection from gamma rays.

Analysis of Zora Neale Hurston’s Spunk Essay

Zora Neale Hurston’s use of language in her short story Spunk allows the reader to become part of the community in which this story takes place. The story is told from the point of view of the characters, and Hurston writes the dialogue in their broken English dialect. Although the language is somewhat difficult to understand initially, it adds to the mystique of the story. Spunk is a story about a man that steals another man’s wife, kills the woman’s husband and then he ends up dying from an accident at the saw mill. Spunk believed that it was Lena’s husband, Joe Kanty, who shoved him into the circular saw, and the people in the village agreed that Joe Kanty had come back to get revenge. The language used by the characters helps to establish the setting of the story and gives the reader an understanding of why voodoo is a plausible explanation for the outcome. â€Å"Looka theah folkses!† is what Elijah Mosley states to the others in the store. This is the first indication that the characters in this short story are not the most educated, and are probably from some small backwoods town. We quickly get confirmation of this when we learn that he is alerting them that Spunk Banks, a giant, brown-skinned man, â€Å"who aint skeered of nothin’ on God’s green footstool†, is sauntering up the one street in the village, with a small pretty woman clinging lovingly to his arm. Clearly, the store is where people hang out, and everyone knows that the woman with Spunk is Lena Kanty, Joe’s wife. Coming from a large city, I would not expect everyone to know each other, so seeing a couple walking down the street would not be significant to me. In this context however, I understand that something is not right and trouble is coming. When Joe walked in to the store, the talking ceased; the men looked at each other and winked. â€Å"Say, Joe, how’s everything up yo’ way? How’s yo’ wife?† asked Elijah. Spoken like a friend, but it is clear that he is trying to start some mess. â€Å"Aw â€Å"Lige, you oughtn’t to do nothin’ like that† Walter grumbled. This dialogue makes the conflict between Spunk and Joe very clear. Not only does Joe know that his wife is going out with Spunk, but everybody in the town knows. This is a brilliant way to draw the reader into the story; we feel bad for Joe. His pride is at stake and he has no alternative but to take some action against Spunk. Joe knows that his razor is no match for Spunk’s gun, but his back is against the wall. He is the laughing stock of the town because Spunk has made a fool of him. â€Å"Well,† Spunk announced calmly, â€Å"Joe come out there wid  a meatax an’ made me kill him.† The men glared at Elijah, accusingly. His words had pushed Joe to do something and Spunk had killed him. Now that Joe was dead, the expectation would be for Spunk and Lena to move forward with their relationship. â€Å"Joe’s death was a clear case of self defense, the trial was a short one, and Spunk walked out of the court house to freedom again†. Spunk was free, but now the excitement begins. Zora Neale Hurston uses symbolism to introduce the reader to the world of voodoo. Hurston had visited Haiti and Jamaica in the 1930s and had become very interested in the practice of voodoo. Elijah tells us in the story that Spunk sees a black bob-cat that â€Å"looked him in the eye, an’ howled right at him†. The thing got Spunk so nervoused up he couldn’t shoot. Spunk says it was Joe done sneaked back from Hell!† Later in the story, Elijah tells us that Spunk dies from being cut by the saw and Spunk believed that Joe had pushed him in the back. Elijah believed it too. Revenge is a powerful emotion and in this story, it is the best explanation for Spunk’s death. Based on the dynamics of the town, everyone believed it to be possible that Joe caused Spunk’s death. Because they believed it, I believed it. It is their world. Zora Neal Hurston was criticized by other African American writers for her use of dialect and folk speech. Richard Wright was one of her harshest critics and likened Hurston’s technique â€Å"to that of a minstrel show designed to appease a white audience† (www.pbs.org).Given the time frame, the Harlem Renaissance, it is understandable that Zora Neale Hurston may be criticized. The Harlem Renaissance was a cultural movement which redefined how America, and the world, viewed African Americans, so her folk speech could be seen as perpetuating main stream society’s view of African Americans as ignorant and incapable of speaking in complete sentences. However, others, such as philosopher and critic Alain Locke, praised her. He considered Hurston’s â€Å"gift for poetic phrase and rare dialect, a welcome replacement for so much faulty local color fiction about Negroes† (www.pbs.org). The language in this short story allowed the reader to enter this community and gain an understanding of their world.

Brittany Burnett Cognitive Psych 310 Research Paper 4/30/15 Prosopagnosia: Facial Blindness Introduction Insight on prosopagnosia Imagine lacking the ability to recognize the familiar face of a loved one or spouse. Or having to rely on voices, clothing, and certain attributes of that individual in order to have some kind of knowledge on who they actually are. This condition is defined as Prosopagnosia; known as face blindness or facial agnostic. According to Barton (2008), it was first described as a consequence of cerebral damage by Quaking and Bordello in 1867. This term comes from the Greek word â€Å"face† and â€Å"lack of knowledge.† Stated by the National Institute of Neurological Disorders and Stroke (2007), Prosopagnosia is anticipated to be the result of damages, abnormalities, or destruction in the right fusiform gyrus; part of the brain that controls the perception of faces and the functionality of memory in the neural system. This deficit can be present from birth, the result of a stroke, a traumatic brain injury, or neurodegenerative diseases. In order to help an individual with Pros opagnosia, it is essential to develop compensatory or redeeming strategies, as well as the use of clues or attributes to help them better identify individuals.
