Test 3/4 Ch. 16 Defining Psychological Disorders Defining Psychological Disorders What's normal and what's abnormal? Can you be atypical and not have a disorder? Psychological Disorders a harmful dysfunction in which behavior is judged to be atypical, disturbing, maladaptive, and unjustifiable What is atypical? disturbing? maladaptive? unjustifiable? Why is it so important to diagnose someone correctly with a disorder? 1 psychological disorders.notebook Defining Psychological Disorders The answer is yes That is why you must also consider the behavior to be disturbing standards of acceptability vary with different cultures one example of how acceptability of disorders can vary in one culture is: from 1952 to Dec. 9, 1973 homesexuality was considered a disorder in the DSM on Dec. 10, 1973 it was not later nicotine dependence was added to the DSM March 05, 2014 Defining Psychological Disorders many clinicians focus on the maladaptive part of the definition to diagnose someone with a disorder for example they see nicotine dependence a disorder when it becomes selfdestructive they see a behavior as a possible disorder when it becomes disabling maladaptiveness has become a key element when defining disorder the behaviors must be distressing or disabling or put one at greatly increased risk of suffering or death an intense fear of spiders may be irrational but it does not impair your life like a disorder Understanding Psychological Disorders in the past people have blamed disorders on outside forces like the stars, godlike powers, or evil spirits if this was the case, then the cure was simply to get rid of the outside force mad people were often put in zoolike conditions or given therapies appropriate to a demon sometimes beaten, burned, pulling teeth, or even castration 2 psychological disorders.notebook Understanding Psychological Disorders March 05, 2014 Understanding Psychological Disorders Medical Perspective Medical Perspective Philippe Pinel of France said madness was not demon possession but a sickness of the mind caused by stress and inhumane conditions physicians began to look for ways to treat psychological disorders through medicine Pinel believed in mortal treatment unchaining them, talking with them, and replacing this new focus was called the mental health movement a mental illness needs to be diagnosed on the basis of symptoms and cured through therapy brutality with gentleness, isolation with activity, the therapy may include treatment in a psychiatric and filth with clean air and sun hospital he believed if you boosted their moral you improved their behavior medical model concept that diseases have physical causes that can be diagnosed, treated, and cured(often) 3 psychological disorders.notebook Understanding Psychological Disorders March 05, 2014 Understanding Psychological Disorders Medical Perspective BioPsychoSocial Perspective with the medical model being followed, hospitals started to replace asylums for dealing with "mad" people today psychologists say that all behavior, whether called normal or disordered arise from in the interaction of nature over time the medical perspective has gained more and more credibility as doctors are finding more ways to deal with disorders through medicine or some form of medical treatment to say a person is mental ill is to say the condition is solely internal maybe the issue is a growth blocking influence in the environment, in the person's current interpretations of events, or in the person's bad habits and poor social skills evidence of this is that some cultures are culturally bound Understanding Psychological Disorders Understanding Psychological Disorders BioPsychoSocial Perspective BioPsychoSocial Perspective schizophrenia and depression seem to be worldwide BioPsychoSocial Perspective a contemporary perspective which assumes that biological, psychological, and sociocultural factors combine and interact to produce psychological disorders anorexia and bulimia seem to only occur in western cultures susto which is a fear of black magic seems to only occur in Latin America a fear of social anxiety about one's appearance with a readiness to blush and a fear of eye contact appears only in Japan they recognize that the body and mind cannot be separated stress and negative emotions can lead to physical illness they all seem to have similar causes but very different symptoms 4 psychological disorders.notebook Classifying Psychological Disorders classification in science creates order in psychology, classification orders and describes symptoms classification in psychology also looks to predict the disorders future course, imply appropriate treatment, and stimulate research into its causes the way for classifying psychological disorders is the American Psychiatric Association's Diagnostic and Statistical Manual of Mental Disorders(Fourth Edition) also called the DSMIV March 05, 2014 Classifying Psychological Disorders many people do not like the DSM because it diagnoses people's problems in terms of their symptoms which says that it is a mental illness they do however still see it as a very practical tool when diagnosing and treating people with disorders health insurance companies require a DSMIV diagnosis before they will pay for therapy DSMIV defines 17 major categories of mental disorder the DSMIV describes the disorders and lists their prevalence without presuming to explain their causes this is a 1994 model that is currently being revised and will be the DSMV Classifying Psychological Disorders DSMIV mentions something called neurotic disorders a psychological disorder that is usually distressing but that allows one to think rationally and function socially this term is often considered to be too vague so it is not used often the DSM also talks about psychotic disorders a disorder in which a person loses contact with Classifying Psychological Disorders DSMIV categories must be reliable What does this mean? some critics say the DSMIV is too vague and can bring any kind of behavior within the compass of psychiatry some say that the number of disorder categories has grown too much from 60 in the 1950's to 400 today 30 percent of adults meet the criteria for at least one psychiatric ailment reality, experiencing irrational ideas and distorted perceptions 5 psychological disorders.notebook Labeling Psychological Disorders once someone is labeled, they are viewed differently March 05, 2014 Labeling Psychological Disorders David Rosenhan's study labels guide our perceptions and our interpretations of people all eight participants were diagnosed as being ill David Rosenhan conducted a study to test this the patients exhibited no further symptoms until being released on an average of 19 days later, he and seven others went to mental hospital the clinicians were able to discover the cuases of admissions offices, complaining of hearing voices their disorders after analyzing their life histories that were saying empty, hollow, and thud they said one person was reacting to mixed apart from this complaint and giving false names emotions about his parents and occupations, they answered all the questions even the normal behaviors of the patients, such as truthfully taking notes, were often misinterpreted as symptoms Labeling Psychological Disorders Ellen Langer conducted another study where people rated an interviewee as either normal or out of the ordinary all viewers saw the same tape those who watched the unlabeled interviewees perceived them as normal those who watched supposed patients perceived them as different from most people Rosenhan discovered that labels can be useful but also they can have a life and an influence of their own Labeling Psychological Disorders Stewart Page experiment pg. 625 paragraph 2 the media can often affect people's stereotypes of disorders movies often portray mental health patients as homicidal or as freaks they are also seen as violent or alcoholics 9 in 10 people with disorders are in fact not dangerous they are instead anxious, depressed, or withdrawn if used correctly labels can help doctors to properly treat someone suffering from a mental disorder 6 psychological disorders.notebook Anxiety Disorders March 05, 2014 Anxiety Disorders anxiety is a

compulsions arise, reinforcement helps maintain them anxiety can develop from a classical conditioning of fear when something bad happens, people become apprehensive when they go back to the place where it happened sometimes fears can be a result of stimulus generalization avoiding or escaping the feared situation reduces anxiety, thus reinforcing the phobic behavior we can also learn fear through observational learning by observing others' fears when someone fears height after a fall also fears airplanes without ever flying in one Anxiety Disorders Anxiety Disorders Explaining Anxiety
