prefrontal cortex and antisocial behavior, studies have shown impairments on other areas of the brain. Parts of the brain like the hippocampus, cingulate and temporal cortex. (Raine & Yange ,2008), cited in Raine (2008).
These impairments are caused back to genetics, which Raine hypotheses with two simple reasons. One being that the studies examining antisocial individuals who have impairments in the prefrontal cortex, did not account for environmental risk factors or drug/alcohol abuse.(Raine et al.,2000) cited in Raine (2008). Another reason, is that the use of MRI images and studies show how genes makeup 90% of the volume represented in the prefrontal. (Raine et al.,2000) cited in Raine (2008). Raine uses these two arguments to state that genetics play key roles in structural impairments in antisocial people. …show more content…
He refers to a chart explaining the impaired brain regions risk factors relating to antisocial behavior. However, some of these risk factors do not lead straight to antisocial/aggressive behavior they still pave the way to that direction. (Raine,2008) For example, in the ventral-orbitofrontal (frontal cortex) risk factor is decision making. (Raine,2008) The outcome of this can lead to bad life judgments. (Raine, 2008) This lack of moral decision making can be linked to antisocial behavior which is found in antisocial individuals.
However, to fully understand the causes of antisocial behavior researches still take account of the role of the environment has on antisocial people. The other 50% of antisocial behavior is by environmental behavior. (Raine, 2008) While genes cannot be fixed, psychological influence can make structural modifications to a person’s DNA causing antisocial behavior. (Raine, 2008) One example, is violence in households or birth problems combined can lead to antisocial behavior adult violent offenses.(Raine,2008) Same can be said

The essay will also go into detailed by supplying a lesson plan which will include the objectives/goals, accommodations/modifications, strategies, assessments, activities as well as including brief description of the student by submitting the student’s age, grade, disability strength, and weaknesses. Hearing and Visual Impairments Hearing is a complex process of changing sound waves into the neural signals which can be translated by the brain into sounds. Within the inner ear is the Cochlea, which changes sound waves into neutral signals. The signals are sent to the brain through the auditory nerve. Where the visual impairment is also a complex process, light enters the eye through the pupil and is collected by photoreceptor neurons in the retina. Signals are then sent to a neuron network that then generates electrical impulses which goes to the brain. The legal definition of a hearing impairment is “a full or partial decrease in the ability to detect or understand sounds. It can range from a mild hearing loss to total deafness” (Hearing Impairment Law and Legal Definition...

Effect of Social Stigma on the Mentally Ill

...of laziness and substance abuse. Social stigma reduces opportunities available for people with serious mental illnesses (Johnstone, 2001). Medicalization is expected to be a strategy that could be used to reduce blame and stigma, although those who oppose this have said to proceed with caution as attributing mental illness to biogenetic causes may cause unnecessary side effects that could worsen prejudice and rejection (Kvaale, 2013). This essay will review the definitions of mental illness and stigma and the impact that social stigma has on people with these illnesses. It will look at whether increased ‘medicalization’ of mental illness, as thought by the biogenetic explanations, has any impact on public attitudes towards people with such illnesses. Perceptions on mental illness is not always accurate as definitions have mostly been biased over the years. One of the definitions used to describe the mentally ill were “mentally-disordered, mad, or crazy”. Mental illness is a well-known, medically diagnosable illness that causes impairment of one’s cognitive and social abilities. In the middle ages, people with a mental illness were thought to be examples of weakness of mankind. People with mental illnesses were put in prison as criminals and sometimes put to death (Corrigan, 2002). A wider and more...

...of its grammatical rules. A better description of memory could be ‘the ability to retain and utilize acquired information or knowledge’. Memory is an integral part of our existence, yet it is only vaguely understood. Through empirical studies on people, the methods of cognitive psychology have lead to some useful descriptions, distinctions and theoretical advances in our understanding of different types of memory. These approaches have paid little attention to the biological substrate of memory – the brain. This is probably partly because, until recently, the tremendous complexity of the brain has hampered our ability to gain useful insights into memory from it. But now, our understanding of the brain is beginning to reach a level of sophistication that may allow this. Tentative links between brain processes and cognitive theories are beginning to emerge in our quest to understand memory. 1 This essay is about some of these tentative links between brain and mind, and how they are may set the stage for some...

Impact of Sickle Cells on Individual

...Freddie Ntunga | Student ID Number: 21608670 Bucks New University Abstract An Essay Discusing the ImpacT of Sickle Cells on an Individual Health & Illness across the Life Span Introduction The concept of health is purely abstract in form and therefore remains indefinable to a great extent. It may be referred to an aspect that is considered to be prima facie with regard to the fulfilment of all kinds of objectives of human life. Being healthy does not essentially refer to being disease free only, as the World Health Organiastion definition of health encompasses a state of well being from the mental, psychological, social and physical perspectives. For providing a comprehensive definition to the concept of health it is vital to focus on the various aspects of health. The definitions of health can either address the functional needs of the humans which would put more attention on the individual’s ability to deal with various kind of situations and head towards its destination or from the humanist approach it can be considered as the state of self actualization that can be linked with empowerment. Health in other words can be stated as a pulpit which begets achievement. Health is the result of the natural environment, the built up environment and the social environment that the individuals are surrounded with from the time of its very conception ( Zhang et al,.2011). The natural environment constitutes the genetic background of the individuals involving certain unique...
