The Multi Store Model Of Memory And Research Into...

Discuss how memory can be explained with reference to models of memory and research into Eyewitness Testimony. Introduction The investigation into memory - how we encode, store and retrieve data - made great advances in the 20th century. Along with biological influences memories define who we are, without them our individuality would be lost. This essay will scrutinize the multi-store model of memory and working model of memory to determine their legitimacy. Each model will be examined on its merits at how it explains cognitive functions. Through tools such as the cognitive interview, eyewitness testimony has been deployed in countries around the world to send millions to lengthy prison sentences. Despite its widespread use, the question remains: how much can we trust someone’s memory in the courtroom? Multi-Store Model of Memory The multi-store model of memory (eg, Atkinson and Shiffrin 1968) claims the memory can be sectioned into three distinctive parts: sensory store, short-term store (STM) and long-term store (LTM). Eysenck and Keane (2005:190) states that data is first encountered by the sensory store, then depending on the attention given, is processed to the STM and finally - if rehearsed - continues to the LTM. There is substantial research backing this model. For example Murdock (1962) found the serial position effect which shows when presented with a list of items, participants recalled those shown at the beginning (primary) and those at the end (recency);Show MoreRelatedReliability of the Human Memory1339 Words   |  5 PagesReliability of the human memory in eyewitness memory In this essay it will be argued how the human memory for recalling details of past events is not reliably accurate and that it will be interpreted through the reliability of memory in eyewitness memory and testimony. The human memory is a complex finding in the cognitive research of psychology, which can be explained by many different contributing factors but eyewitness is dependent upon the accuracy of long-term memory.

Essay2709 Words   |  11 PagesMemory is a capacity that humans rely upon to relate to different events, experiences, conditions, and people. It is a vitally important process and system whereby the brain receives information from (external or internal) stimuli, stores it (encoding), and makes it available on a future occasion (retrieval).

Needless Animal Experimentation is Wrong If penicillin had been tested on guinea pigs, it might never have reached the public. It is lethal to guinea pigs, deactivates the blood system of rabbits and is deadly to cats (Bio-Medical Research). Scientists are pushing for more experiments regardless of the cost to the animals life. One expense is the involvement of killing animals in the pursuit of a pine-scented air freshener(Vergoth,p21). Animals suffering in experimentation labs are in just and cruel to animals. It is wrong to harm an innocent animal of any wrong doing, when the animal doesnt know right from wrong. It is argued that people have an obligation to animals, so that we can protect their welfare. Charles†¦show more content†¦More than five billion dollars of federal tax revenue are spent annually on animal research (Bio-Medical Research). With that money there could be drug rehabilitation programs, nutrition counseling for the disadvantaged, or even improving water and air quality; but instead animals get experimented on. Animals, like the rest of nature, were understood not have any sort of value, except to bring enjoyment to lives. Animal life has some value (Frey, p27). Scientists test products on animals to see if they are safe, or if any side effects may occur. Many different companies use tests on animals, such as: the Draize Test and the LD-50, or Lethal Dose 50 Percent. The Draize Test is used to measure the harmfulness of chemicals found in household products and cosmetics, by observing the damage they cause to the eyes and skin of animals (Product Testing). Albino rabbits are used for the eye irritancy of a solution. The rabbits suffer extreme pain, mutilation and blindness. Often the rabbits eyes are held open with metal clips. The damage to their eyes are irreparable and leave the eyes ulcerated and bleeding. At the end of the test, the animals are killed to see what the internal effects were (Product Testing). The Lethal Dose 50 Test kills half of the test group. This test was developed in the 1920s, and is used to measure the acute toxicity of certain ingredients.

Social Biases free essay sample

Dr. Deirdre Teaford Abstract People behave differently toward other culture and groups and discriminate in many forms of social bias. These biases can impact harshly an individuals career and social life. Discrimination, prejudice, and stereotypes can influence adversely an individuals quality of life. The concept is more prevalent in society that most people realize. This problem could be unfavorable to group cohesion, cooperation, and the success of society. Humans prefer to go with the flow of a crowd. When an idea is chosen by the masses (an entire nations or a small group), the individualized brain enters a kind of hive mind mentality. This causes social norms and behaviors to propagate among the individuals regardless of the evidence in support. This type of social bias is built with the desire to conform or fit in. Social biases have been a barrier humans have experienced from generation to generation. They take short cuts to make sense of the world. We will write a custom essay sample on Social Biases or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Humans have made rash decisions or discriminatory practices based on gender, race, ethnicity, religious affiliation, political preferences, and socioeconomic tatus. Humans have become fallible and has been subjected to their many flaws by making errors in Judgment, memory, and social attribution. Social psychologists have claimed these biases can be eliminated if the individuals have the motivation and capacity to change their attitude. According to Fiske (2010), Some people think bias is a thing of the past, and others think it is a real and present danger that targets diverse social groups (p. 28). Moreover, there are subtle and obvious misunderstandings among groups of individuals that affects the bias of people in heir lives, but strategies for change are possible (Fiske, 2010). In this analysis, the concept of prejudice, stereotyping, and discrimination will be defined. In the same aspect, the analysis will describe the differences between blatant and subtle bias while identifyi ng some common biases that may affect the lives of individuals and Stereotyping, and Discrimination Gender and ethnic stereotypes are inevitable. In the context of affirmative action, the inevitability has played an important practical implication. One arguments against affirmative action is that employers and educational administrators should be ender-blind and colorblind in their hiring and recruiting process (Stewart, Weeks, Lupfer, 2003). Individuals are often hurt by discriminatory and prejudicial behaviors and attitudes. The current laws cannot halt prejudicial or stereotyping attitudes, but they can address instances of discrimination. Discrimination, stereotyping, and prejudice are somewhat similar, but they are very different. Prejudice The operational definition involves reacting fervently to an individual on the basis of ones feelings about the group (Fiske, 2010). It is a belief that formulated without considering the facts. It is also an unwarranted or negative attitude toward a person based on his or her association of a social group. Stereotyping The operational definition entails an individuals cognitive associations and expectations about a group. These expectations will encompass the beliefs about the characteristics of a group (Fiske, 2010). Moreover, it is an indiscriminate belief about a class of people or particular group. Advantage: It allows the individual to respond hastily to certain situations because he or she may had a related experience. Disadvantage: It will make us ignore the differences between people. Discrimination The operational definition involves acting on the basis of ones prejudices and stereotypes, rebuffing equality of treatment that individuals wish to have (Fiske, 2010). Moreover, it is the negative behavior, or actions toward a group of people or individual on the basis of social/race/gender class. In this context, discrimination can be either blatant or subtle. Subtle and Blatant Bias In the last two decades, there is no doubt that women have made strides in the fight for equality. Many can recognize that women have overcome the many prejudices against their participation in the workforce (Earnshaw, 1993). In our society, blatant bias is being replaced by subtle bias to decrease the broad- mindedness for obviously biased behavior. Subtle bias is also acknowledged as modern prejudice. This does not mean that women do not get discriminated at work even though they have achieved equality of opportunity (Earnshaw, 1993). The first generation bias was more hostile towards women who needed to be in home with the children. On this second generation bias, for example, women may get more narrative praise than the male co-workers but low rating point related to Job performance (Earnshaw, 1993). Subtle Bias This particular modern bias is indirect and is manifested by withholding respect and sympathy. It is ambiguous and sometimes involves positive and hostile feelings that can cause extreme responses (Fiske, 2010). Blatant Bias This old-fashioned bias ensues as a result of threats to the struggle for positive group identity. They include segregation, physical attack, extermination, avoidance, opinion clearly in regard to a particular individual or group. Impact of Social Bias The lives of individuals can be influenced by social biases. Negative outcomes like neglect, hostile environment, or avoidance may be created by discrimination. When a biased individual interacts with an outgroup members, the expressed behavior of the individual will solicit negative and ill attitudes. Prejudice will influence the individuals lives with instances of ageism, sexism, and racism that will affect their career and social life. According to Vaish, Grossman, and Woodward (2008), When adults display a negative bias across an array of psychological situations, they will use the negative information instead of the positive one (p. 383). Moreover, the negativity bias may serves as an evolutionary adaptive purpose of helping individuals afely explore and examine the environment to avoid harmful situations (Vaish et. al. , 2008). Two Strategies to Overcome Social Biases There are several strategies to minimize social biases, such as affirmative action, and equal opportunity laws. The majority of these strategies involve constant intergroup contact. The key term for a biased individual is change. Old habits die hard but and individual can break those habits. According to Fiske (2010), Intergroup contact and mutual differentiation are two possible strategies to minimize the bias. Intergroup Contact These are interactions between members of different social groups. During the contact, there is equal status in the groups, there are common goals, and there is no competition but cooperation. They are not easy to meet, but they make complete sense (Fiske, 2010). Mutual Differentiation In this context, mutual differentiation is important for two reasons: (1) People retain awareness of individuals social identity in the contact situation, and (2) Individuals seem typical in the sense that they represent their own groups (Fiske, 2010). In Conclusion The motivation of change is the key to steer away from social biases. The bias will be the individuals preference toward a peculiar way of viewing or thinking omething. This behavior will be influenced by a certain prejudice.
