PSY240 – Lecture 2 9/18/2013 11:04:00 AM We are going to be talking about chapter 1 today and our assignment that is nd going to be due on October 2 Christine – [email protected] (marking final exam) Monika – [email protected] What is abnormal behavior?  It is easy to recognize abnormal behavior, but really hard to define  What constitutes abnormal behavior?  Strange behavior is hard to consider abnormal  DSM 5 has made the definition broader  The definition of a learning disability in children is a deviation of the norm, in mathematics or language abilities  DSM 5 has tried to catch more people who are more pathological  What abnormal means, how it comes about? – it is not easy to define Principles used to establish abnormality are: statistical concept, developmental norm, frequency duration and intensity, and behavioral norms Another word for norm is average – Statistical Concept  How do you determine what average means – you calculate the mean  In an ideal objective world, this is how we would determine what abnormal behavior is  Normal behavior is what most people display  The average number of pieces of information you can keep in your mind is 7  What is the average IQ? – 100 o Your intelligence for your age, is almost the same for all of the people your age – ideally this is what we want to do because we want to ideally define abnormal as a statistical criteria o We would like to collect a lot of data from other people, to see how they feel o What does the normal distribution look like in statistics? – a bell curve o Looking at the behavior seen in the majority of the population, most people think and feel o Is memory a behavior?  Memory is a behavior – I am angry is a behavior  What we are looking at abnormal behavior is abnormal, thoughts, feelings, and actions (all three of these are behaviors) o What could abnormal blowing of the nose be? Statistically?  How frequently you blow your nose, blowing your nose can be abnormal statistically o We consider averages normal – this is what we like to do  Ideally there is a problem – it is restricted to those behaviors that are most common and it disregards behaviors that are favorable  Example: there is a one to one correspondence to people and you  basically taking the average and coming it to yourself  In statistics this is called standard deviation – abnormal standard deviation is how far you are from the averages  If 1 standard deviation away from average 2/3 of the population has a higher mark than you  Using the statistical criteria for what normal is, it disregards deviant behavior – giftedness is favorable  Babies born above average weight are considered to be “healthy” – positive comments, and babies that are below the average weight are considered to be sick – negative comments  We don’t consider gifted children as psychopathological – and when we look at the other side of that they have unfavorable behaviors  There are behaviors on the DSM that are bad, but we all participate in them  almost everyone has participated in this activity but the DSM calls is psychopathology which is SUBSTANCE ABUSE (coffee drinkers, drinkers, smokers, etc.) – something that is used to alter your mind, and when you are not using it, you start to withdraw  using statistical criteria which is common behaviors that are unfavorable  disregards deviant behaviors that are favorable  includes common behaviors that are unfavorable  there are certain behaviors that are distinctive – such as schizophrenia – in most societies it is so distinctive that it would be considered abnormal o in north American culture, religious experiences this is normal o there are many cultural differences o the content of abnormal behavior varies among different cultures o in cultural norms, and environment situations, they’re defined  Example: “I am going to get naked now okay?”  Is this normal or abnormal? – is it so abnormal that is it illegal  Situation defined; it is normal to get naked in a locker room  If you ended up punching your sister when you were 7 it would not be illegal (situation defined)  There is an acknowledgement about certain behaviors and certain ways of thinking –  There is a name for these norms, and it is developmental norms (milestone)  another word for it o Wetting the bed when you are 5 is normal, but when you are 25 it is considered abnormal o When you are stringing telegraphic speech o Age 2 – telegraphic speech (I want a cookie) o Age 3 – if your child is not speaking, a little bit of concern o Age 4 – if your child is still not speaking, there is a higher level of concern o Age 5 – time to see a professional Frequency, intensity, and duration  We are still trying to use statistics to figure out what abnormal is – we are looking at deviation at a norm from these three perspectives  Depression is a sad affect – depression is referred to a mood disorder o Things that should make you happy, chocolate, raise at work, doesn’t make you happy anymore – there is something in your life that is stopping
