Working Memory Analysis
Chapter 7 speaks of memory, the function of short term/long term memory, and the way we encode/retrieve information. “Memory is the mental capacity to encode, store and retrieve information.” (Gerrig 196) In this chapter I found that within working memory there are four components within working memory, a phonological loop, a visual spatial sketchpad, the central executive and the episodic buffer. Before I continue to explain each component, I’d like to first explain what working memory is. “Working memory is a memory source that is used to accomplish tasks such as reasoning and language comprehension; consists of the 4 components.” (Gerrig 203) Phonological loop controls speech-based information within the short-term memory, for …show more content…
“The cognitive process is one of the higher mental processes, such as perception, memory, language, problem solving, and abstract thinking.” (Gerrig 233) I’d like to discuss language behaviors in animals. Sue Savage-Rumbaugh conducted research on bonobos, a species of ape that is similar to a chimpanzee and closely related to humans. Kanzi and Mulika are two chimps that were studied during this research. With no training, these chimps acquired meanings of plastic symbols by observing other humans and bonobos using them. Kanzi and Mulika were able to understand spoken English and basic commands. For example, when Sue would tell Kanzi “Take off Sue’s shoe,” he would understand and follow the …show more content…
“Crystallized intelligence is the knowledge a person already acquired, this can be measured by vocabulary, mathematics, and information tests.” (Gerrig 279) Fluid intelligence is the ability to attack complex and abstract problems. I believe we all have both types of intelligence. Some may have one more than others but I do believe they exist in ones mind. In Chapter 10 I will discuss human development across the human life span. “Developmental psychology is the branch of psychology concerned with interaction between physical and psychological processes and with stages of growth from conception throughout the entire life span.” (Gerrig 298) The stages within a life span begin in the prenatal stage; the age period begins at birth and continues into infancy that is the first 18 months. The last stage is late adulthood and the age period is between 65 and

    Many people think that human development means childhood development from birth to adolescence. This assumption had been supported by the developmental theories of Freud and Piaget. However, we will learn throughout this course that development does not end at the start of adulthood; it continues till the end-of-life. This is the life span perspective of development. Describe the importance of the life span perspective of development.…

    The working memory model is the part of the short term memory which is governed by the ‘central executive which monitors and coordinates the operation of the store systems; Phonological loop and visuo – spatial sketchpad. The phonological loop allows sounds to be stored for brief periods. The visuo spatial sketchpad allows visual and spatial information to be stored for brief periods. The two slave systems within the WMM are completely separate and can work individually.…

    Baddeley and Hitch (1974) developed an alternative model of short-term memory which they called the working memory model. The working memory model consists of four components. The central executive which controls and co-ordinates the operation of two subsystems, the phonological loop and the visuo-spatial sketchpad. The central executive controls attention and coordinates the actions of the other components, it can briefly store information, but has a limited capacity. The phonological loop consists of two parts, the articulatory control system and the phonological store. The articulatory control system (the inner voice) where information is rehearsed sub vocally and has a capacity of about 2 seconds. The phonological store (the inner ear) stores information in speech-based form, the speech input is held for a brief duration. The third component, the visuo-spatial sketchpad, mentally manipulates images and space, for example it is used when a person imagines the encodes visual information in terms of separate objects as well as the arrangement of these objects in one's visual field. The final component, episodic buffer, receives input from many sources, temporarily stores this information, and then puts them together in order to construct a mental episode of what is being experienced right now.…

    Theories were established in learning the dynamic aspects of human growth and development. Human growth refers to the physical aspects that occur as human life exist from the start of conception to the end of life. It can be quantified and measured through an individual’s physiological attributes such as the height, weight, dental progression, and bone structure. Development pertains to the stages and characteristics describing the complexity of cognitive skills and social skills being established by an individual as they age from their conception or fetal stage and matures into adulthood. Theories of development were created from different school of thoughts that are products from processes of methodological thinking in providing a basis of intellectual arguments to address the questions regarding human behaviors and actions through age, contact to other individuals, experiences and situations, and their environment.…

    Baddeley and Hitch (1974) criticised the multi-store model for being a very simplistic view of memory. They saw short term memory as a store that had many individual sections inside it. This was supported by patient KF who had epilepsy, the doctor wanted to try and remedy this by removing his hippocampus. This surgery was done, however instead of fixing his epilepsy, it damaged his short term memory, yet he still had his long term memory intact. In the multi-store model it states that in order to have long term memory, one needs to have gone through the several stores, such as the sensory memory store, the short term memory and then by adding meaning and rehearsal, into the long term memory store. Seen as patient KF could still encode long term memory, it is obvious that he still had part of his short term memory that was intact, proposing the idea that there was in fact many sections to the short term memory. Therefore, Baddeley and Hitch proposed the working memory model. The first key component of the working memory model is the central executive; this is like the boss of the working memory model. It controls all of the other slave systems in it, and orders them to do what they do, when they need to do it. Put simply, it directs attention to particular tasks, and how to allocate resources. One study to support this is Gathercole and Baddeley (1993) study on the Visio-spacial sketch pad. This is a dual task study, which involved asking participants to follow a moving point of light, whilst describing the angles of the hollow angle 'F '. This was found to be difficult because both activities are competing from the same slave system. They were then asked to perform a verbal task whilst following light (using the phonological loop). These are process from two different slave systems, and so they are not competing for the resource. This resulted in this task being performed much better. The second key component of the working memory model is the phonological loop…

    According to Berger (2010), a developmental theory is a systematic statement of principles and generalizations that provide a framework for understanding how and why people change as they get older. After many years of observations, theorists have tried to use their findings to construct a sort of map of the human path from an infant through childhood and finally through adulthood. Psychoanalytic theory, behaviorism, and cognitive theory are three theories that focus on human development.…

    The field of study that examines patterns of growth, change, and stability in behavior that occur throughout the entire lifespan is called lifespan development. Lifespan development takes a scientific approach in its study of growth, change, and stability. This development emphases on human development. Developmentalists study the course of development in nonhuman species, the most popular examine growth and change in people. In contrast I will focus on the ways people and myself change and grow during our lives, with the consideration of stability in our live span. Together, these findings suggest that we will go through different developments and stages from Infancy, through childhood and adolescence, and to marriage and parenthood.…

    Working memory plays a central role in all forms of complex thinking, such as reasoning, problem solving, and language comprehension. However, its function in language comprehension is especially evident because comprehension entails processing a sequence of symbols that is produced and perceived over time. Working memory plays a critical role in storing the intermediate and final products of a reader 's or listener 's computations as she or he constructs and integrates ideas from the stream of successive words in a text or spoken discourse. In addition to its role in storage, working memory can also be viewed as the pool of operational resources that perform the symbolic computations and thereby…
