SIGMUND FREUD'S STRUCTURE OF PERSONALITY

It’s the first comprehensive theory of personality.
The structure of personality:
Id-
·         the original system of personality
·         the matrix within which the ego and the superego become differentiated
·         consists of everything psychological that is inherited and present at birth
·         reservoir of psychic energy
·         it is in the close touch from bodily processes
·         Freud called the id the “true psychic reality” because it represents the inner world of subjective experience and has no knowledge of objective reality
·         It cannot tolerate increases of energy that are experienced as uncomfortable states of tension
·         Consequently, when tension increases through external or internal stimulation, the id functions to discharge the tension immediately- THIS IS CALLED PLEASURE PRINCIPLE
·         To accomplish its aim, id uses 2 processes:
1.   Reflex actions:  It is inborn
          They are automatic reactions
          They reduce tension immediately
2.   Primary processes:It forms an image of the object that will remove the tension
e.g.- nocturnal dream
note- the hallucinatory experience in which the desired object is present in the form of a memory image is called wish-fulfillment.
Ego-
·         Comes into existence because the needs of the organism require appropriate transactions within the objective world of reality
·         The basic distinction between the id and the ego is that the id knows only the subjective reality of the mind whereas the ego distinguishes between things in the mind and things in the external world.
·         Obeys the reality principle, the aim of reality principle is to prevent the discharge of tension until an object that is appropriate for the satisfaction of the need has been discovered.
·         Operates by the means of secondary process, the ego formulates a plan for the satisfaction of the need and then tests the plan, usually by some kind of action, to see whether or not it will work.
Superego-
·         It is the internal representative of the traditional values and ideals of society as interpreted to the child by its parents and enforced by means of a system of rewards and punishments imposed upon the child.
·         The moral arm of personality
·         Represents the ideal rather than the real or the desire
·         There are 2 subsystems of superego:
1.   Conscience- whatever parents say is improper and punish the child for doing tends to become incorporated into conscience. It punishes the person by making him feel guilty.
2.   Ego-ideal- whatever parents approve of and reward the child for doing tends to become incorporated into its ego-ideal. It reward the person by making him or her feel proud.
This incorporation happens through introjection.

On the development of superego the self-control is substituted for parental-control.

SUBSTANCE ABUSE EXPLAINED

Any abused substance produce some form of intoxication that alters –
·         Judgment
·         Perception
·          Attention or
·         Physical control.
Many substances may bring on withdrawal- an effect caused by cessation or reduction in the amount of the substance used. Withdrawal can range from mild anxiety to seizures and hallucinations.
Drug overuse may cause death.
Tolerance- increasingly larger amount of the drug is required to produce the same level of intoxication.
TOBACCO
According to WHO, tobacco use is one of the biggest public health threats the world has ever faced.
Reasons for using tobacco: a. pleasure
      b. improved performance
      c. vigilance
     d. relief of depression
      e. curbing hunger
      f. weight control
The addicting substance in cigarettes is nicotine:
It changes how the brain and body function.
It can both invigorate and relax a smoker, depending on how much and how often they smoke.
It causes a rapid release of adrenaline which causes:  
·         rapid heartbeat
·         increased blood pressure
·         rapid and shallow breathing

v  Adrenaline causes the release of glucose in blood and nicotine blocks the release of insulin therefore making people hyperglycemic (having more sugar than usual in their blood). Therefore, people eat less (they think it curbs their appetite)
v  Nicotine increases the basal metabolic rate slightly (therefore weight lose takes place but it is not as healthy as exercising)
v  Overtime nicotine can increase the level of LDL cholesterol that damages the arteries and causes a heart attack or stroke.
Cigarette smoke- contains thousands of other chemicals that also damage health.
Health hazards- heart disease, lung cancer and emphysema, peptide ulcer and stroke.
Withdrawal symptoms of smoking-
·         anxiety
·         hunger
·         sleep deprivation
·         depression

Research Design

What is the need for research?
 It is a task to conduct research in order to inform a case involves carrying out experimental tests in order to  :  1. Illustrate a point 2. provide further information.
And aims to
·         Discover
·         Interpret
·         Revise existing knowledge.
What is a research design?
·         It is a tool which assists in defining the topic under investigation.
·         Describes the method by which the topic will be explored
·         Analyses the sources which will be utilized
·         Often necessary to revise and enhance design when more is known about the topic under investigation
·         Initial research design is a brief general statement of topic under investigation( consists of the methods and the sources)
What to consider while writing an initial research design?
·         Topic under investigation? What is the hypothesis? Define as exactly as possible what it is that is being investigated.
·         Reason of particular investigation being conducted
·         Literature review
·         Is the research different and original?
·         Merits and shortcomings of the existing state of knowledge
·         Importance and significance of the chosen research topic.
