INTRO -Pathological = impairs the individual’s ability to function What is Abnormal? -Deviation from normality in an ‘undesirable’ way 1. Statistically unusual a. The behavior must be comparatively rare 2. Culturally deviant a. The behavior must be outside of the cultural norm b. Different from what would be expected from a person in that culture 3. Distress a. The behavior must cause significant discomfort to the individual or others 4. Impairs functioning a. The behavior “gets in the way” of otherwise normal activity Abnormality in Children (addition of first 4 bullets) Kids do some rare (and sometimes deviant) things all the time Parameters of Deviance: 5. Pervasive a. The behavior must be present across contexts (home, school, etc.) 6. Persistent a. Behavior does not dissipate over time 7. Stunts normal development a. The behavior must obstruct otherwise “normal” growth b. The child does not meet developmental milestones because of the behavior Definitions: -Nomothetic = what all people with the disorder necessarily share in common -Idiographic = aspects that are utterly unique to the individual with the disorder Establishing Causality 1. Temporal precedence a. The cause must come before the effect 2. Correlation a. There must be a relationship between the presence of the cause and the presence of the effect b. Correlation is necessary but not sufficient to imply causality c. Positive correlation (ear size and reading ability) i. Spurious correlation- outwardly similar or corresponding to something without having its genuine qualities ii. Things can be correlated, but the correlation is due to a 3 rd variable that you don’t know about 3. Nonspuriousness a. The effect cannot be the result of an extraneous third variable b. Example: Trauma and depression c. That is, the effect is specifically due to the cause and not an alternate explanation
