DEFINITIONS OF ABNORMALITY (STATISTICAL INFREQUENCY)
Terms in this set (5)
WHAT IS STATISTICAL INFREQUENCY?
any relative usual behaviour that is the majority is classed as normal, any other behaviours are classed as abnormal.
WHAT IS AN EXAMPLE OF STATISTICAL INFREQUENCY?
example= human characteristic's, the majority of peoples scores will cluster round the average, some will be lower, others will be higher. this is called normal distribution. IQ SCORES- average = 100 = (68% of population), 2% have lower than 70- these individuals are classed as abnormal (intellectual disability disorder)
EVALUATION: Real world application
used in clinical practise and for diagnosis to assess severity of individuals symptoms. BECK DEPRESSION INVENTORY- a score of 30+ on test (top 5%) is interpreted as indicating severe depression. Value of statistical infrequency is critical to diagnostics
Evaluation: Unusual characteristics can be positive
people with a high IQ are not seen as abnormal, yet they aren't the average. examples show that being on one end of psychological spectrum doesn't necessarily make someone abnormal. This means it is never sufficient as the sole base of defining abnormality
EVALUATION: benefits vs problems
people benefit from being classed as abnormal. someone with BDI can access support services or benefit from therapy in their daily lives. However, there is a social stigma with associated labels meaning their life wouldn't benefit from a label
