Idiographic & Nomathetic Flashcards
Explain the two approaches
Debate over which is preferable in Psychology
- Detailed study of one individual or group provides in-depth understanding (idiographic) or
- Study of larger groups with the aim of discovering universal principles or ‘laws’ of behaviour (nomothetic)
What are the key concepts of the debate
INEPO
Idiographic approach and qualitative research
Nomothetic approach and quant research
Both examples in Psychology
Objective versus subjective
Tell me about Idiographic and qualitative research
When the number of participants is small, often a single indivudal or group. Initil fous o about understanding the individual but generalisations may be based on findings
Qualitative research useed.
Examples in psychology idiographic
Humanistic approach - rogers concept of counselling was based on his work as a therapist. His ‘theory/ of the role of unconditional positive regard in self-development was based on his in-depth study of his clients
Freud’s explanation of a phobia was based on the detailed study of Little Hands over many years ago
Nomothetic approach and quantitive research
General principles of behaviour are developed and are then applied to individual situations, such as in therapy
Quant research - hypotheses formulated, sample of people / animals gathered and dt analyse to test statistical significance then seek to quantify human behaviour (can make large scale laws/generalisations)
Examples in Psychology
Skinner studied animals to develop general laws of learning
Sperry’s split brain research involved repeat testing and was in part the basis for understanding hemispheric lateralisation
Objective versus subjective
The nomothetic approach seeks standardised methods of assessing people. This ensures true replication occurs across samples of behaviour and removes the contaminating influence of bias
Idiographic - tends to to believe that objectivity is possible in psychological research. It is people’s individual experience of their unique context that is important.
What are two strengths and two limitations for the approaches
Strength: Idio and nomo approaches work together
Both fit with the aims of science
Weakness: in nomothetic the individual experience is lost
Idiographic on its own is restricted
Point about a continuum
Tell me the strength of the idio and nomo approaches working together
The idiographic approach uses in-depth qualitative methods which compliments the nomothetic approach by providing detail
In depth case studies such as HM (damaged memory from removal of hippocampus and amygdala) may reveal insights about normal functioning which contribute to our overall understanding
This suggests that even though the focus in fewer individuals, the idiographic approach may help from ‘scientific’ laws of behaviour
Say the counterpoint about the idio approach
The idio approach on its own is restricted as there is no baseline for comparison, also unscientific and subjective
this suggests that it is difficult to build effective general theories of human behaviour in the complete absence of the nomo approach
Tell me about how both approaches fit with the aims of science
Nomo research seeks objectivity through standardisation, control and statistical testing.
Idio approach seeks objectivity through triangulation (comparing a range of studies and reflexivity (researchers examine own biases).
This suggests that both the nomo and idio approach raise psychology’s status as a science.
Tell me the limitation of the nomothetic approach
One limitation is that the individual experience is lost
Nomathetic approach focuses on general laws and may ‘lose the whole person’ within psychology. For example, knowing about a 1% lifetime risk of schizophrenia says little about what it is like having the disorder, which might be useful for therapeutic ideas
this means in its search for general laws of behaviour, the nomo approach may sometimes fail to relate to experience.
Evaluation: distinct or complimentary?
Each approach is distinct and appropriate for different situations. However, they may also be two ends of a continuum eh when diagnosing personality disorders, clinicians begin with general nomo criteria ten focus on individual unique needs.
This suggests that these approaches are both either/or, we can consider the same topic from both perspectives.
