idiographic Vs nomothetic approaches Flashcards
what is the idiographic approach
- focuses more on the individual case
- attempts to understand specific/unique behaviour and gain detailed insights
- doesn’t aim to formulate general behavioural laws
what methods does the idiographic approach use
- qualitative methods, studying individuals in depth
- focuses more on the quality of information rather than quantity
- unstructured interviews, observations and case studies
what’re idiographic examples in psychology
- Humanistic approach
- case studies eg Phineas Gage and HM
what is the nomothetic approach
- studies human behaviour via development of general principles
- studies a large number of people
- seeks to make generalisations or develop laws/theories about human behaviour
what methods do nomothetic approaches use
- quantitative
- measures of central tendency (mean, median, and mode) and dispersion graphs and statistical analysis
- nomothetic is more scientific than ideographic
what’re nomothetic examples in psychology
- behaviourist approach (skinners rats)
- biological (brain scans in countless individuals)
- attachment (44 thieves, strange situation)
what’re the main assumptions of the idiographic approach
- people are unique identities
- people have their own subjective experiences and motivationd
- you cannot compare unique individuals to larger groups, standards or norms
what’re the main assumptions of the nomothetic approach
- psychologists should produce general laws of human behaviour
- provides a ‘benchmark’ against which people can be compared, classified and measured
- large numbers of people should be studied to establish ways that people are similar to each other
what is the support for idiographic approaches
- uses in depth qualitative methods to provide a detailed account of the individual
- a single case study can lead to further nomothetic studies (eg HM)
what is the limitation of the idiographic approach
- can be very time consuming to collect and analyse such detailed information (often interviews)
- the reliance on case studies makes the approach less scientific as conclusions often rely on subjective interpretations of the researcher and so are open to bias
what is the support for the nomothetic approach
- the process tends to be very scientific, testing often with standardised procedures and statistical data analysis
- this has allowed psychologists to establish behavioural norms of behaviour (eg IQ norm of 100) which gives greater scientific credibility
what is the limitation of the nomothetic approach
the nomothetic approach often loses ‘the whole person’, eg we may know the %risk of developing OCD but we don’t know how it feels to live with OCD. this means that it loses some external validity
