Psychological Disorders (Unit 1)

January 20, 2015
Abnormal Psychology

Psychological Disorder- a “harmful dysfunction” in which behavior is judged to be atypical, disturbing, maladaptive and unjustifiable.
DSM IV- diagnostic statistical manual of mental disorders: the big book of disorders
-DSM will classify disorders ad escribe the symptoms
-DSM will NOT explain the causes of possible cures

·         Two major classifications in the DSM
1.) Neurotic Disorders- Distressing but one can still function in society and act rationally
2.) Psychotic Disorders- Person loses contact with reality, experiences distorted perceptions

Anxiety Disorders

·         A group of conditions where the primary symptoms are anxiety or defense against anxiety
·         The patient fears something awful will happen to them
·         They are in a state of intense apprehension, uneasiness, uncertainty, or fear



  • Phobia- A person experiences sudden episodes of intense dread
  • Generalized Anxiety Disorder (GAD)- An anxiety disorder in which a person is continuously tense, apprehensive and in a state of autonomic nervous system arousal.The patient is constantly tense and worried, feels inadequate, is over sensitive, can’t concentrate and suffers insomnia.
  • Panic Disorders- Anxiety disorder marked by a minute long episode of intense dread in which a person experiences terror and accompanying chest pain, choking and other frightening sensations
Obsessive- Compulsive disorder (OCD)
·         Persistent unwanted thoughts (obsessions) cause someone to feel the need (compulsion) to engage in a particular action.
·         Obsession about dirt and germs may lead to compulsive hand washing.

Post-Traumatic Stress Disorder (PTSD)
·         Flashbacks or nightmares following a person’s involvement in or observation of an extremely stressful event.
·         Memories of the event cause anxiety.




January 21, 2014
  • ·         Somatoform disorders- occur when a person manifests a psychological problem through a physiological symptoms
  • ·         Hypochondriasis- has frequent physical complaints for which medical doctors are unable to locate the cause- believe they are minor issues.

  • ·         Conversion Disorder- report the existence of severe physical problems with no biological reason. Like blindness or paralysis


·         Dissociative disorders 
      (3 types)- these disorders involve a disruption in the conscious process.
1.       Psychogenic Amnesia- a person cannot remember things with no physiological basis for the disruption in memory.
2.       Dissociative Fugue- People with psychogenic amnesia find themselves in an unfamiliar environment.
3.       Dissociative Identity disorder (DID)- People with DID commonly have a history of childhood abuse or trauma, diagnosed birth to 18.


·         
      Mood Disorders
      Mood Disorders: Experience extreme or inappropriate emotion
·         Major Depression- unhappy for at least two weeks with no apparent cause. (Depression is the common cold of psychological disorders.)

·         Dysthymic Disorder- suffering from mild depression every day for at least two years

·         Seasonal Affective Disorder (SAD)- experience depression during the winter months. Based not on temperature, but on amount of sunlight.

·         Bipolar Disorder- formally maniac depression, Involves periods of depression and manic episodes (involve feeling of high energy). Some get confident, some get irritable.

Schizophrenic Disorders

·         About 1 in every 100 people are diagnosed with schizophrenia.
Symptoms of Schizophrenia:
1.       Disorganized thinking:
·         The thinking of a person with schizophrenia is fragmented and bizarre and distorted with false beliefs.
·         Disorganized thinking comes from a breakdown in selective attention- they cannot filter out information

 Delusions (false beliefs):
 Delusions of :
Persecution (fear)
Grandeur (god)

2.       Disturbed Perceptions: Hallucinations- sensory experiences without sensory stimulations.
3.       Inappropriate emotions and actions:
·         Laugh at inappropriate times
·         Flat effect- reduction in emotions
·         Senseless, compulsive acts
·         Catatonia- motionless waxy flexibility

Positive v. Negative Symptoms

  3. Catatonic Schizophrenia: Parrot like repeating of another’s speech and movements
  4. Undifferentiated Schizophrenia: Many and varied symptoms.



Intro to Psychology

January 7th, 2015
Psychology: The science of behavior and mental processes
Science: Based on research
Behavior: Observable ; measurable
January 8, 2015
Goals of Psychology:
·         Observe
·         Predict
·         Explain
·         Describe
·         Control

Prescientific Psychology
·         Wilheim Wundt: Father of Psychology (first psychology lab)

Structuralism
-          Broke down mental process into the most basic components (structures) of conscious experience
-          What did you see? Hear? Taste? Smell? Feel? (Introspection)
Functionalism
-          Focused less on the How of sensation and perception, but rather on the Why.
-          Emphasized the process of how thoughts are formed , changed and how thoughts formed, changed, and how they adapted.


7 Perspectives of Psychology
 
1.       Neuroscience Prospective
-          Focus on how the physical body and brain create our emotion, 
      memories and sensory experiences.

-          2.   Evolutionary Perspective
-          Focuses on Darwinism
-          We behave the way we do because we inherited those behaviors
-          Thus, those behaviors must have helped ensure our ancestors survival

-          3. Psychodynamic Perspective
-          Fathered by Sigmund Freud
-          Our behavior comes from unconscious drives

-          4. Behavioral Perspective
-          Focuses on our observational behaviors
-          Only focuses on the behaviors that impair our living, and attempts to change them

-          5. Cognitive Perspective
-          Focuses on how we think (or encode information)

-          6. Social- Cultural Perspective
-          Focus on how your culture affects your behavior

-          7. Humanistic Perspective
-          Focuses on positive growth
-          Attempt to seek self- actualization

Business Graph

Expansionary (Growth): Real output in the economy is increasing, and the unemployment rate is declining. (Ex: building)
Peak: Real output is at its highest point
Contractionary (Recession): Real output in the economy is decreasing and the unemployment rate is rising.

Trough: Reach your lowest point in GDP. (Trough to trough- 6 Year duration)

January 16th, 2015


Surplus
Quantity supplied>Quantity demanded
QS>QD
Shortage
Quantity demanded>Quantity supplied
QD>QS

·         Equilibrium: The point in which supply and demand intersect, at this point resources are used efficiently.
·         When resources are not used efficiently, Disequilibrium occurs.


Price Ceiling: A government imposed price control on how high a price can be charged for a product of service. (Ex: Mortgage in NYC)

Price Floor: A government imposed price control on how low someone can charge for a product or service. (Ex: Minimum wage)

January 15th,2015


Price Elasticity of Demand: Tells how drastically buyers will cut back or increase their demand for a good when price rises or falls.



Elastic Demand: When demand changes greatly due to change in price.
“Wants”: Find substitutes
E is greater than 1

Inelastic Demand: Demand will not change even if the price changes.
“Needs”: Few substitutes (Ex: gas, milk, salt)
E is less than 1

Unit or Unitary Elastic
E = 1


1. % ∆ in Quantity
(New Quantity- Old Quantity)/ Old Quantity
2. % ∆ in Price
(New Price- Old Price)/ Old Price
3. Price Elasticity of Demand (PED)
% ∆ in Quantity/ % ∆ in Price ( Make sure to take absolute value)
=E (Inelastic or Elastic or Unitary Elastic)


January 14th, 2015



Supply
Supply: The Quantities that producers/ sellers are willing and able to produce/ sell at various prices.


The Law of Supply: There is a direct relationship between price and th quantity demanded. As price increases, quantity increases. As price decreases, quantity decreases.
·         ∆ in price is caused by ∆ in quantity supplied

∆ in supply is caused by:
1.            in anything except price, such as factor price
2.            in resource
3.            in technology or technique
4.            in taxes or subsidies
5.            in prices of other goods
6.            in expectations
7.            in the number of supplies


Total Revenue


Total Revenue: Price X Quantity
Marginal Cost: The cost of producing one more unit of a good.
Fixed Cost: The cost that does NOT change, no matter how much is produced.

Variable Cost: A cost that fluctuates; does not depend on how much is produced. (Ex: Electricity, gas, phones)


Now that you learned supply and demand, here is a video of a creepy teacher reteaching it.

Demand
Demand Schedule:

Demand Curve

Demand Increase: Curve shifts right
Demand Decrease: Curve shifts left
Demand: The quantities that people are willing and able to buy at various prices.
The Law of Demand: There is an inverse relationship between price and quantity demanded. As price decreases quantity increases.
·         ∆ in price is caused by ∆ in quantity demanded


       ∆ in Demand is caused by:
       5 Determinents of Demand
1.    ∆ in buyers taste- (advertising)
2.    ∆ in number of buyers- (population)
3.    (∆ in income)-
1.    Normal goods: Goods that buyers buy more of when their income rises.
2.    Inferior goods: Goods that buyers buy less of when their income rises.
4.  ∆ Of price of related good:
       1. Substitute goods: Goods that serve roughly the same purpose to buyers (Ex: Coke & Pepsi)
       2. Complimentart goods: Goods that are often consumed together (Ex: Cars & Gas)

5.  ∆ in expectations- Thinking of the future

Production Possibilities Graphs
Key Assumptions:
1. Two goods are produced
2. Full employment
3. Fixed resources (land, labor/capital)
4. Fixed state of technology

5. No international trade

January 8th, 2014: Unit 1

Four Factors of Production
1.    Land- natural resources
2.    Labor- work force
3.    Capital-
Physical: human made objects used to create another goods and services ; 
ex: buildings, goods, machinery
Human: knowledge/ skills gained through work/ education
4.    Entrepreneurship: innovation and risk taking
Trade-offs: alternatives that we give up whenever we choose on a course of action over the other.
Opportunity cost: the most desirable alternative given up by making a decision.
“Guns and Butter”: Where the government is allocating the money
Ex: guns= military butter= agriculture


Production Possibilities
 Graph: Alternative ways to use resources


Point D: Attainable, but inefficient
Reasons:
·         recession,
·         water/ famine
·         underemployment
·         unemployment
·         population loss

Point B and A: Attainable, but efficient

Point C: Unattainable
Reasons:
·         Economic growth
·         Technology
·         New resources discovered

January 7th, 2015

·         Macroeconomics- Study of the entire economy
·         Microeconomics- Study of part of the economy, how households and firms make decisions and how they interact in markets (supply and demand)/ market structures
Fact vs. Opinion
Fact: Positive economics- claims that attempt to describe the world as is, it is very descriptive.
Example: Minimum wage laws causes unemployment
Opinion: Normative economics- claims that attempt to prescribe how the world should be.
Example: The government should raise the minimum wage.
Scarcity vs. Shortage
Scarcity: The most fundamental economic problem that all societies face, try to satisfy unlimited wants with limited resources
Shortage: A situation in which quantity demanded is greater than quantity supplied
Ex: water; oil
Goods vs. Services
Goods: Bought, Sold, Traded, Produced
Consumer goods: goods that are intended for final use by the consumer
Capital goods: items used in the production of other goods

Services: any work performed Ex: Barber, plumber
