Q

What is the complementary approach?

A

Idiographic and nomothetic approaches should not be seen as conflicting. It is more helpful to see them as complementary.

Q

What did Milon and Davis suggest?

A

Suggested research should start with a nomothetic approach –> produce laws –> focus on idiographic understanding.

Q

A03: Useful for treatments

A

However, as drug treatments are not successful for all patients, some psychologists argue that alternate treatments (e.g. Cognitive Behavioural Therapy) which are based on an idiographic approach are more suitable for treating individuals with such conditions, as they seek to understand and explain the disorder from a patient’s point of view.

Q

A03: Scientific basis

A

This is a strength of the nomothetic approach, as its highly scientific nature means that results attained are objective and reliable as the conditions used to attain them are standardised and have a high degree of control. As a result of this, the findings have scientific credibility and can be used to prove theories proposed by psychologists.

Q

A03: Time-consuming

A

The idiographic approach is very time consuming. It takes a lot of time and money to study individuals in depth. If a researcher is using the nomothetic approach once a questionnaire, psychometric test or experiment has been designed data can be collected relatively quickly.

Q

A03: Generalising issues

A

That being said, theories developed from case studies may struggle to be generalised beyond the individual, reducing the ecological validity of these findings, As a result, generalisations cannot be made without further examples, meaning that the idiographic approach alone cannot be used to improve the scientific credibility of psychology.

17
Q

The interactionist approach

A

Despite this, idiographic and nomothetic approaches could be used to complement each other. Milon and Davis (1996) suggest that research should start with a nomothetic approach, and once general laws have been established, researchers can then use a more idiographic approach. Doing this allows researchers to have the reliability given by nomothetic approaches, and the more detailed findings attained by employing an idiographic approach.

Q

A03: Loses sight of the whole person

A

Furthermore, some psychologists argue that the nomothetic approach loses sight of the ‘whole person’, due to its fixation on quantitative data and statistical analysis. Furthermore, these psychologists also claim that the nomothetic approaches only provides a superficial understanding of human behaviour. For example, Milgram’s research found that 65% of participants obeyed an authority figure and inflicted a 450-volt electric shock because they were ordered to do so. However, the results fail to provide an explanation of why each person obeyed, and there may have been very different circumstances that led to the obedience found in each participant.
