Rather than reducing behaviour to one factor, such as biology or conditioning, it considers the full range of influences on a person, including their thoughts, emotions, experiences, relationships, and potential for growth. For example, Maslow's theory considered physical, emotional, social and self-fulfilment needs.
This contrasts with the reductionism found in other approaches and offers a more comprehensive and meaningful understanding of individuals. By recognising the complexity of human behaviour, the humanistic approach is more reflective of real-life experience and better suited to understanding the subjective, personal nature of psychological wellbeing. It is particularly effective in counselling settings, where the therapist must understand the client as a whole person, not just a set of symptoms.
