Psychopathology = study of psychological disorders
1. Statistical infrequency
• Occurs when an individual has a less common characteristic
• Any usual behaviour or characteristics are ‘normal’, so any unusual
behaviours or characteristics are ‘abnormal’
• How often we come across these unusual behaviours
Examples:
• Using Normal distribution we can see whether the characteristic is
‘normal’ For example , the average IQ is 100 and 2% of people
have a score below 70 = ‘abnormal’ likely to have intellectual
disability disorder
• Being more depressed than most of the population

2. Deviation from social norms
• Behaviour that is different from the accepted standards in society are
classified as abnormal.
• Bases abnormality on whether the norm / what is accepted is being
followed
• Social norms vary between generations and cultures
Examples:
• Homosexuality was considered abnormal in the UK and still is in
some cultures
• Antisocial personality disorder (psychopathy) is classed as
abnormal because there’s an absence of acting ethically and
conforming to moral standards

3. Failure to function adequately
• Occurs when someone is unable to cope with the ordinary demands
of everyday life
• Includes not maintaining basic standards of nutrition and hygiene
• Rosenhan and Seligman say people fail to function adequately when:
• They no longer conform to standard interpersonal rules eg eye contact
• They experience severe personal distress
• Their behaviour becomes irrational or dangerous
