Self Destructive Behavior and Role of the I function
The I function describes all behavior associated with the notion of self. Is there really a specific I function and what is its role exactly? Because the I function is linked to the self, one would think that it would prevent harmful behaviors. However, there are cases where the I function does not intervene to terminate detrimental actions for example addiction and a mental disorder called Lesch-Nyhan syndrome. In both cases, a person is harming themselves and can not seem to stop. Does the I function play a role in self-destructive behavior? By researching addiction, more specifically alcoholism, and Lesch-Nyhan syndrome, it is clear that the I function can be overruled by other structures of the brain even when harm to the body is one of the final outcomes.
Addiction is defined as a physical and psychological dependence on a substance or behavior (1). Initially the behavior simply satisfies the person but turns into addiction when strong urges accompany the behavior and the person feels that it is needed to avoid painful feelings. What is causing the urges? The brain can be divided into two parts, the primitive brain and the new brain or the neocortex (2). The primitive or beast brain is responsible for survival appetites which are associated with physical pleasure. However, in order to satisfy the urges, the beast brain must communicate to the neocortex and cause the necessary motions to get the drug or exhibit the behavior. According to Rational Recovery (2), the neocortex, or you can overcome the beast brain. Is this alluding to the I function? If this is true, why did the behavior become an addiction in the first place? Where was the I function during that first d...

... the desires of the limbic system, but when necessary the limbic system can ignore the inhibition. There are three structures previously mentioned, the neocortex, the limbic system and the I function. Certainly the first two exist and have specific locations. The I function is only a hypothetical at this point. It fits conveniently into hypotheses. It has not yet been proven wrong but at the same time more evidence is found indicating that the I function can not be included in the same category as structures like the limbic system or the neocortex. It does not have a definite location or a definite purpose. Does the I function exist or is it just wishful thinking that somewhere in the brain is the self or the soul which has some control over our actions whether or not the influence is beneficial.

One bacterium was gram negative. It underwent four different tests. These tests were the EMB test (Eosin Mehylene Blue), the Sulfur Indole Motility (SIM) test, the Urease test, and the Simmon’s Citrate Utilization test. The EMB test checks for a bacteria’s ability to ferment lactose. This test is accomplished by placing the bacteria on Eosin Methylene Blue agar. The agar is selective for gram negative bacteria and those bacteria that can ferment lactose will have colored growth, usually a metallic green sheen.
According to Leshner, drug addiction is a chronic brain disease that is expressed in the form of compulsive behaviors (Leshner, 2001). He believes that drug addiction is influence by both biological, and behavioral factors, and to solve this addiction problem we need to focus on these same factors. On the other hand, Neil Levy argues that addiction is not a brain disease rather it is a behavioral disorder embedded in social context (Levy, 2013). I believe, drug addiction is a recurring brain disease that can be healed when we alter and eliminate all the factors that are reinforcing drug addiction.
The first step to the unknown is selecting an actual organism. The best way to select a culture is based on a high-quality distribution. Equally important, shaking up the broth tube facilitates in the distribution. Upon selection, a gram check for purity is performed. Step by step instructions for this procedure can be found in Benson’s, Microbiological Applications p. 99. Furthermore, an aseptic technique must be performed for this test and the entire tests following the unknown. The purpose of this test is to differentiate between gram positive and gram-negative bacteria. The key indicator of gram-positive bacteria is a purple stain and a pink stain for gram-negative bacteria. A slide is viewed with a microscope under oil immersion. Equally

Some people have impulses that are not conducive to the decorum of society. Some people cannot explain their need, their impulse, to shout obscenities, to make strange faces at strangers, or to excessively mimic others around them. Tourette's Syndrome is one example of a disorder that causes a person to be overwhelmed by impulses to say and do things that they cannot control. Do impulses have varying degrees? And can some people more efficiently control these impulses, or channel the impulsive thoughts into something other than actions? Is our behavior conducive to the ability to monitor numerous impulses of all degrees? And I wonder what role I-function plays in behavior, if behavior is explained in terms of controlled impulses.
Coined by theorist Sigmund Freud, the psychodymanic approach to therapy revolves around the interaction between the conscious and the unconscious. It is believed that the mind is made up for three entities; the Id, Ego,& Superego. The id is known for its pleasure seeking drive and impulsiveness. Often referred to as the “devil on your shoulder” the id exhibits very little self control and is often linked with the unconscious mind. Driven by sex, violence, and impulsivity, the id has been known to encourage risky behavior that normally would not occur. If the id were dominant, a person would behave in a devious, and socially unacceptable manner. Contrary to the id, the superego acts as the “angel on ones shoulder”. As stated in Day,2008, “when the superego is in charge, we are perfectionistic and uptight and demand too much of ourselves.” The superego acts as the conscience by reflecting social standards learned through observation. When the superego is allowed to take control, it sets such high expectations and demands, that is is too difficult to reach such high standards. The only way to stop the pendulum of the psyche from swinging to either extreme is the presence of the ego. The ego is the mediator between the superego and the id, providing moral reasoning and the principal of reality. The reality principle acknowledge that one must not act out id impulses, but also realizes that one cannot live up to the demands of the superego (Day, 2008). The ego helps moderate between these two extremes with the use of defense mechanisms.
George F. Koob defines addiction as a compulsion to take a drug without control over the intake and a chronic relapse disorder (1). The Diagnostic and Statistical Manual of Mental Disorders of the American Psychiatric Association defined "substance dependence" as a syndrome basically equivalent to addiction, and the diagnostic criteria used to describe the symptoms of substance dependence to a large extent define compulsion and loss of control of drug intake (1). Considering drug addiction as a disorder implies that there are some biological factors as well as social factors.
Development is a never ending cycle in life. Each person begins to develop from conception until passing away. Now, while most people think that development starts after birth that is incorrect. Development starts as soon as the baby is conceived. Everything that a woman carrying a baby does or takes place in will translate into the baby. The baby shares a blood flow with the mother. Drugs, even legal drugs, will go into the mother’s blood stream which will then go into the baby’s blood stream. The “maternal blood flows through the uterine arteries to the spaces housing the placenta, and it returns through the uterine vein to the maternal circulation” (Santrock, 2012, p. 80). This means that anything that enters into the blood stream will also affect the baby. Each type of drug is under a certain category. Psychoactive drugs are drugs that are constantly being studier. According to Santrock (2012), psychoactive drugs are drugs that act on the nervous system to alter states of consciousness, modify perception, and change moods. (p.83). They come in three categories: stimulants, depressants, and hallucinogens. Stimulants include caffeine, cocaine, methamphetamine and nicotine. Some people say that pregnant woman do not know what taking these into their system is doing to their baby. Stimulants are becoming more popular and there effects need to be studied and known. Each stimulant affects the baby in short-term and long-term.
Addiction is a chronic, often relapsing brain disease. It causes compulsive drug seeking and use despite harmful consequences to the addicted person as well as the people around that person. The abuse of drugs -- even prescription drugs -- leads to changes in the structure and function of the brain.

Due to the availability of news and media in today’s technologically advanced society, many people are aware of the violent acts that are committed every day all throughout the world. In addition, the technological advances of today’s society have continued to fuel one of the most successful industries of the present day: the video game industry. Many people have been eager to blame the video game industry for the violent acts that are committed throughout the world because the video game industry has continued to target an audience that seemingly craves an increasing amount of violence, and they criticize the video game industry for its complete lack of restrictions on the sale of violent video games to teenagers. However, although some experts believe that playing violent video games may perpetuate a violent disposition in a teenager, it has been demonstrated that
