PSY240 Abnormal Psychology Lecture 2 Sep,19 ,2012 Reviews from Last lecture: How to define abnormal behavior? a) Statistical Criteria b) Cultural norms c) Developmental norms d) Frequency intensity, duration  We are looking for the behaviors that interfere with the daily functions. Psychologist: Assessment -> diagnoses -> treatment Etiology: is a study of the causes and prevalent of abnormal behaviors. Etiological models of abnormal behavior: a) medical-disease models In current/modern psychopathology, people tend to use medical disease models to treat disorders. Schizophrenia is the only disorder that’s proved medicines would help (biological origin). You cannot treat schizophrenia with only psychotherapist since it was a brain disorder. (too much dopamine=schizophrenia) Genetic models # We use twins study (identical twins), when one twin has schizophrenia; the chance for another one to develop the disorder is 50% # Stress is a big factor of developments of psychopathology. Biochemical models # Depression does not always response well to the same drug to each person; schizophrenia does. # These drugs are manipulating neurotransmitters. (Depression = too little serotonin) Neurophysiological models Psychoanalytic model # Freud: Mental disorder is because of the intro psychic conflict eternally. b) social/environmental models Sociocultural models # This emphasizes on the socio/culture determines. # Stressors in a person’s life -> Death of family, losing a job, divorcing but as well as starting a new job, marrying etc. These can all affect psychopathology. More stress you have the more possible you will develop psycho disorder. Learning models #The model comes from Pavlov, and Skinner. The models are about how we learn about the environments. The depression that causes by learning model suggests that we think we are worthless from the interaction with other people or the stimulus. We need a relearning therapist to treat this kind of depression. Humanistic models # Humanistic paradigm. It focuses on one’s positive views about what’s going around them and themselves. It’s not interested to explore about unconscious or learning.  What is Assessment in psychology? Three major categories: 1. We interview 2. Testing 3.Observation or behavior assessment # Interview is about the verbal responses from the patients, which is also the most common in the assessments treating adult patients. (self-reports) # To treat the children, observation of behaviors is the most common assessment.  First stage of the assessment is “referral”, who comes from a family position (or general patrician). They will write down what the general problem might be and refer the patient to a more specific help.  In the referral, the basic information is given, such as duration, unset and medical stasis. (*Call morbid)  Observation: Simply looking at the physical behaviors of the patients in a specific situation.  The observer bias can be aware on the observation.  Valuable information of observation of assessment: 5 categories 1. General appearance (How they present themselves can tell you a lot about themselves such as their clothing, or cuts, bruces on themselves) 2. Emotional gestures/facial expressions (body languages; it is not just what they wear but their body languages.) One of the most comment emotion gesture: anxiety. 3. Grouse movements. (The area of the assessment of the responsibility. It can be influence by different factors. It can be related to
