Introduction to Cognitive Psychology

Linda is an ex substance abuser and has experienced a few relapses. Linda is 33 and is in good health besides damage to her lungs due to smoking crack cocaine. She is concerned about her memory, since she misplaces her car keys at home and losing her car in the parking lot. Linda is also telling stories regarding her children and is later corrected for telling the story about the wrong child. Linda has no brain damage, besides the decay of her memory due to her substance abuse. When one has brain damage, or anyone uses any illicit drug, it affects the function of the brain. She believes she might be suffering from a neurological disorder. I believe the effect she is experiencing is due to her past substance use. Cocaine is known to cause several neurological disorders due to the fact that the crystalline free-base form is water insoluble which when smoking or free basing results in an instantaneous high contributing to the rapid absorption through the large pulmonary surface area and swift penetration to the brain. Cocaine can be absorbed from the mucous membrane, therefore causing neurological complications (Agarwal, 2013). Since she is healthy I would rule out that it is a neurological disorder and that it is just poor memory. Substance abuse affects the brain stem, the limbic system, and the cerebral cortex since drugs are chemicals. Cocaine causes nerve cells to release excessive amounts of natural neurotransmitters or prevent the normal recycling of these brain chemicals. This leads to an exaggerated message in the brain, ultimately wreaking havoc on the communication channels (Seikel, 2013). In which I believe explains Linda’s confusion, etc.
In regards to the information processing system, I will use Atkinson and Schifrin theory, to best explain how memories are created, stored and…...

...Encryption Standard. 7. What is SHA1, and what is it used for? The Secure Hash Algorithm 1 (SHA-1) is a well-known and currently secure cryptographic hash function designed by the NSA. Is it used similarly to TripleDES or are they different? They are the same, they both use algorithms. 8. Provide and explanation for the difference between symmetric keys and asymmetric keys in a PKI? symmetric-key: It only needs one key to encrypt the message. And both user only need the same key to decode the message. And the in order to create the key is by moving the bit. asymmetric-key: It needs two different keys- public key and private key. Everyone can see the public key and only the person who has private key can decode the message. 9. What is a common drawback to Encrypting using enterprise level tools such as PGP? Complexity, cost, lack of scalability, and lack of interoperability with VoIP systems. So even though implementing encryption is appealing, many businesses may balk at the potential obstacles. 10. What is the difference between PGB and GPG? “PGP” stands for “Pretty Good Privacy.” It was developed by Phil Zimmermann. At first it was written as copyrighted freeware under the Gnu Public License. Later, PGP was upgraded and made into a propriety program. The rights for this program are traded around. The reason for this upgrade was legal defense costs and royalty issues related to the export laws of the USA. Now the PGP program is owned by PGP......

...Psychology June 22, 2010 Unit 9 Final Project: Urie Bronfenbrenner developed the ecological systems theory to explain how everything in a child and the child's environment affects how a child grows and develops. He labeled different aspects or levels of the environment that influence children's development, including the microsystem, the mesosystem, the exosystem, and the macrosystem (Bukatko, 2008). Bronfenbrenner’s theory stresses the need to understand how children develop in everyday life. The development issue I chose to discuss is Fetal Alcohol Syndrome (FAS) and how the surroundings and everyday life affects the development. There are different characteristics that accompany FAS in the different stages of a child's life. "At birth, infants with intrauterine exposure to alcohol frequently have low birth rate; pre-term delivery; a small head circumference; and the characteristic facial features of the eyes, nose, and mouth" (Phelps, 1995, p. 204). Some of the facial abnormalities that are common of children with FAS are: microcephaly, small eye openings, broad nasal bridge, flattened mid-faces, thin upper lip, skin folds at the corners of the eyes, indistinct groove on the upper lip, and an abnormal smallness of the lower jaw (Wekselman, Spiering, Hetteberg, Kenner, & Flandermeyer, 1995; Phelps, 1995). These infants also display developmental delays, psychomotor retardation, and cognitive deficits. As a child with FAS...

I choose this topic because this is the age group that I would like to work with once I obtain my Bachelors of Science in Psychology with a minor in Child Development, and I also find children in this age group to be very interesting especially on the way they view life around them and how independent they become. The Stages of Development: Cognitive Development: Language begins to develop rapidly, also children begin to use language as their communication tool and their vocabulary increases tremendously. Physical Development: Each skill that the child already has is practiced and becomes perfected. Therefore at this stage the child applies and develops mastery motor skills in challenging situations they are faced with. Social Development: At this age and in this stage the child will begin to learn the concept of right from wrong. Also at this stage he or she begins to imitate what he or she sees an individual do, whether a family member or friend at school. Children at this stage and age also begin to interact with their peers. Theories: Erickson’s Psychosocial Theory of Development: “highlights the child’s composite need to initiate......

...Emotional Intelligence is important because it helps a person to be able to recognize and manage their feelings’ appropriately. It also helps a person to be able to recognize and effectively deal with others’ emotions. It also helps people to motivate themselves and build successful relationships.

...Unit 9 Seminar August 31, 2012 MT140: Introduction to Management Unit 9 Seminar Many people encounter communication problems and sometimes they can be avoided and others not so much. Everyone uses a process of perception and filtering and it’s easy to mistake perception which will lead to a misunderstanding as does filtering. It’s best to try and use clear, slow speech when communicating with someone, be sure to repeat, pause, and use gestures. Word choice and body language are what I believe to be very important in communication. These two can clash very quickly and easily if not done properly, it can also cause confusion. There are also different kinds of communication channels that we have such as oral and written. Oral communication is face to face discussion, telephone, and even through presentation and speech. The written communication is emails, memos, letters, reports, computer files, and more. The steps to managing change can also vary, but change can happen constantly and unpredictably. There are several ways you can take to managing the change and they could be by first building a case for the change. What’s the reason for the change and why is it so important that it happens within the business? Next, would to be sharing the vision and values these are important because you would want your company to know what the vision is and values. This way everyone is on board and has and understanding to why it is happening. Thirdly, you will need the recourses......

...Unit 9 Assignment PS210: History of Psychology Kaplan University August 18, 2014 Psychology today reflects the history and origins of psychology. In order to have a full understanding of psychology, you need to spend some time exploring its history and origins. Structuralism, in psychology is defined as the study of the elements of consciousness. It focuses on recurring patterns of thought and behaviors and it also involves more psychological aspect of human studies rather than social structures. Structuralist use numerous techniques to examine one's own conscious feelings and thoughts. Functionalism is the study of the mind and how the mind functions to the whole body to adapt into a community or a society. It is also a perspective or theory that tries to explain and justify why society is the way it is. According to different psychologist it can explain social structures and social behavior of a society and their functions. In the functionalist perspective, society is thought to function like organisms, with many social institutions working together to maintain and reproduce societies. Functionalists studied the mind not from the standpoint of its composition, its mental elements or its structure but as a conglomerate or accumulation of functions and processes (Schultz, 2012). William James was the major contributor to functionalism. James broadened the field of structuralism to more of an developmental, education, and gender......

...Unit 9 Assignment 1. Refer to the sets of the aggregate demand, short-run aggregate supply, and long-run aggregate supply curves. Use the graphs to explain the process and steps by which each of the following economic scenarios will shift the economy from one long-run macroeconomic equilibrium to another equilibrium. Under each scenario, elaborate the short-run and long-run effects of the shifts in the aggregate demand and aggregate supply curves on the aggregate price level and aggregate output (real GDP). a. Suppose the household wealth decreases due to a decline in the stock market asset prices (See the set of graphs below and pay attention to the 3-stage shifts in graphs). Answer: In graph one the decline in the stock market asset price causes the AD line to shift downward, decreasing. The long-run equilibrium in the first graph is the point where all three of the lines (LRAS, S1, and D1) are connecting. With a lower GDP, the aggregated demand curve shifts to the left (D1 to D2) creating a new equilibrium point at a lower price level. In the second graph it shows a higher supply with the increase in the SRAS (S1 to S2) curve. It will create a new long run equilibrium at a lower price level. In the last graph it shows both the shift in the AS curve from AD1 to AD2 due to the decrease and it shows the increase in the SRAS curve from S1 to S2 due to higher supplies. It shows both the old and new equilibrium along the LRAS curve. The first one being higher......

...Unit 9 Assignment Kaplan University CJ211: Police Operations Police Technology has evolved so much from the time of the first modern officer. With population increasing, law enforcement officers needed technology that gave them the chance to do their jobs quicker and better. Instead of having to shoot a suspect, officers now have less than lethal weaponry which makes it possible to incapacitate using different methods. Crime mapping allows police departments to find correlations between crimes in different areas of the city. In order for law enforcement officers to contain traffic pursuits they now use pursuit management technology which helps to stop a pursuit before something gets damaged or somebody gets hurt. Police officers sometimes have to deal with violent, combative people and while dealing with them have to keep in mind the use-of-force protocols. Less-lethal technologies give police an alternative to using physical force options that potentially are more dangerous to the officers and the suspects (National Institute of Justice). There are seven types of less-than lethal technology. Conducted Energy Devices, such as the Taser and Stun gun, can induce involuntary muscle contractions that temporarily incapacitate people. Directed Energy Devices use radiated energy to achieve the same effect as blunt force, without injury. Chemicals, including pepper spray, tear gas, and stink bombs, are used to incapacitate suspects so officers can catch them and......

...Effects of Bullying John Wells Maryville University Observations of Children on a Psychiatric Unit This part of the paper will cover my observations of patient-to-patient aggression in the form of verbal, emotional, and physical bullying on an inpatient behavioral health unit, and its psychological effects. Over the span of 3 weeks I observed the interactions between children on a psychiatric unit where I work. Each week I spent one shift making observations. I do not typically work the children's unit, but I was able to float to this unit and make observations during the time where the kids were in the day area interacting. The type of bullying I saw the most was in the form of verbal. Verbal bullying happened 100 percent of the time I was on the unit. It involved children of all ages, race, and gender. The verbal aggression was consistently focused on intellect, appearance, skin color, lifestyle choices, and ethnicity. The most common form of verbal aggression was directed at appearance and intellect. This was very interesting to me because our patients have general learning disabilities. I also saw emotional bullying. This type of bullying included the spread of rumors, excluding others from activities, and refusal of talking to other patients. The last type of bullying I observed was physical bullying. This type of bullying was less likely to happen on our unit. I felt that the presence of staff and security discouraged this type of bullying.  However, it did......
