P: The humanistic approach has led to practical application in the form of Rogers' client-centred therapy.

E: This is argued to have revolutionised counselling for mental health problems such as depression and anxiety and has therefore helped many people to overcome difficulties they experience in everyday life.

E: This is a strength as the humanistic approach has made a significant contribution to improving people's quality of life, which may also benefit the economy, as people may be more likely to come to work.

P: Humanists reject any attempt to simplify behaviour into smaller components.

E: It considers all components of the body to prevent important aspects from getting overlooked.

E: Therefore, it is not reductionist.

P: Emphasises that humans have free will over their behaviour.

E: Humans have the ability to make genuine choices over their actions

E: Therefore, it is less deterministic than the biological and behaviourist approach

P: Many of the approach's core concepts are abstract and untestable.

E: For example, concepts such as self-actualisation and congruence may be difficult to assess under experimental conditions. As a result, they can't be directly measured and empirical evidence can't be gained to support the key concepts of the theory.

E: This is a weakness as it makes it hard to know how accurate the explanations are as they aren't falsifiable, ultimately reducing the scientific credibility of psychology

P: Culturally biased

E: The humanistic approach values concepts that are valued in individualistic cultures e.g. personal success and self-actualisation. However, collectivist cultures such as China and Korea are focused on community and helping each other, rather than pushing individual, personal growth

E: Therefore, the approach cannot be applied to collectivist cultures, reducing its usefulness
