psychopathology Flashcards
how can statistical frequency show abnormality
- implies that a disorder is abnormal if the frequency is more than two standard deviations away from the mean incidence rate
- people who behave “abnormally” will deviate away from the centre
evaluation of statistical frequency as a definition of abnormality
+ objective and based on data
+ good measure for psychological disorders
- infrequency does not mean abnormality and may be desirable (high IQ)
- abnormality may not be infrequent (anxiety and depression)
- some psychological disorders are difficult to measure objectively
- rely on arbitrary cut off points which may not apply to everyone
- only those that seek help will be included in data
- cultural bias- may be more frequent in other cultures like auditory hallucinations
define social norms
an unwritten rule of society which sets guidelines for behaviour
how can deviation from social norms show abnormality
behaviours which violate these moral standards are seen as abnormal
evaluation of deviation from social norms strengths
+ distinguish between desirable and undesirable behaviours
+ social dimensions can help abnormal individual and wider society by helping them
evaluation of deviation from social norms weaknesses
- beliefs about abnormality and social norms of morally acceptable behaviour change over time- homosexuality was classified as a mental disorder until 1972 so lacks temporal validity
- definition is subjective , basing our assumptions on prevailing social norms
- judgements are related to context of behaviour- hard to know difference between abnormal deviation or harmless eccentricity
- cultural relativism and cultural bias- behaviours in western countries may be different to ethnic minorities, like hearing voice or hallucinations may be “normal” in african and asian cultures
- can be used to justify the removal and discrimination about certain people in society
jahoda’s criteria for deviation from ideal mental health
- positive attitudes towards the self
- personal growth and self actualisation
- resistance to stress
- personal autonomy- independent
- accurate perception of reality
- mastery of environment- ability to love, function in different places, adapt
evaluation of deviation from ideal mental health strengths
+ focuses on what is positive and functional
+ allows for goal setting h- permits the identification of what is needed to achieve normality
+ holistic view and approaches the whole of the human being
evaluation of deviation from ideal mental health weaknesses
- over demanding criteria- meeting all 6 would be difficult
- subjective criteria- vague and difficult to measure
- cultural variation- in some countries personal autonomy or self actualisation is uncommon like in collectivist cultures
- the degree to which people meet the criteria may vary overtime
how can inability to function adequately show abnormality
- unable to navigate everyday life or behave in a necessary way
- cause distress and suffering to the individual, as well as people around them
rosenham and seligman criteria for dysfunctional behaviour
- personal distress
- observer discomfort
- irrational behaviour
- unpredictable
- dysfunctional
DSM assessment rating for functioning adequately
- understanding and communicating
- getting around
- self care
- getting along with other people
- life activities
- participation in society
evaluation of ability to function adequately strengths
- assess degree of abnormality with WHODAS
- focuses on observable behaviour so has empirical evidence
- practical methods for assessment
- personal perspective which helps to recognise personal experience
evaluation of ability to function adequately weaknesses
- abnormality is not always accompanied with dysfunction as people with dangerous personalities can function normally (Harold Shipman)
- subjective to suggest what is dysfunctional or not
- cultural relativism- different diagnosis for different cultures, lower class non white people are often misdiagnosed
- questionnaire limitations like social desirability bias
- people may not be able to function normally for a period of time, which may not be a mental health disorder e.g grief

explains how classical and operant conditioning produce and maintain a phobia
classical conditioning to explain initiation of phobias
- learning through association
- little albert was conditioned to fear white, furry objects as every time he reached for the white rat, a bar was struck and startled him
- generalised to other white, furry objects like santa hats
