Maslow - Humanist
Hierarchy of Needs
Humanist study the whole person.
5 tier model of human needs. 
People are motivated to achieve certain needs and some take precedence over others. Our most basic need is physical survival, and this is the first that motivates our behaviour. Once that level is fulfiled, the next level up is what motivates us. Until we reach self-actualisation.
Personal growth and fulfilment in life is a basic human motive. Each person wants to better themselves and make the world better.
It can be divided into deficiency needs (D) and growth needs (G).
D arise due to deprivation and are said to motivate people when they are unmet. The motivation to fulfil them will become stronger, the longer the duration that they are denied. When D has become 'more of less' satisfied it will go away. For example, the more a person goes without food, the hungrier they will become.
G do not come from a lack of something, rather from a desire to grow as a person. Once G have been reasonably satisfied, you may be able to reach the highest level. Every person is capable of achieving this, however, progress is usually disrupted due to failure to meet D. For example, life experiences such as divorce or going into care can cause an individual to fluctuate between levels.
5 levels
1) Biological - air/food/drink/ warmth/shelter/sex/sleep.
2) Safety - protection from elements/ security/law/stability.
3) Love - friendship/intimacy/ trust/receiving and giving affection/being part of a group.
4) Esteem - for oneself (dignity/achievement/ independence) and for reputation (status/ respect from others).
5) Self-actualisation - realising personal potential/self-fulfilment/ seeking personal growth.
