This essay will engross further into the routes of occupational psychology to understand and differentiate between the similarities and differences of two main theories that are still applicable today when applied to the context of work; this includes one to be Abraham Maslow’s hierarchy of needs model (1954) a pyramid based satisfactory model and the other that is Peter Warr’s Vitamin Model (1987) a unusual analogy of reality.
Abraham Maslow (1954) an adventurous American Psychologist whose main notion of interest was accelerated in the direction of ‘self-actualization’ (Champan, 1995-2010) after meeting a successful researcher named Kurt Goldstein who influenced him in actually taking the topic of humanistic psychology a step forward. The whole creativity of the ‘hierarchy of needs’ was established by studying and observing monkeys to find patterns of behaviour they had addressed based on their needs (Poston, 2009). However, Peter Warr (1987), a Research Professor, focuses on explaining job satisfaction and stimulating the linear relationships that creates a trend in graphs (Jonge et al, 1998) concerning job characteristics and the indices of employee welfare; to achieve this the ‘vitamin model’ was invented. Sir Warr (1987) stresses the importance of work and suggested that certain features at work act like vitamins (Job,2004) as they
