Models and computer simulation

In Chapter 8 it was pointed out that the term 'model' has been used in a number of different ways, and three meanings were distinguished: (1) as synonymous with 'theory'; (2) as inferior to a theory on account of reduced scope and associated confidence; (3) as a particular type of theory, which seeks to explain phenomena by reference to an abstract system or mechanism. One of the foremost proponents of such an approach in psychology has been Deutsch (1960) who sees its advantages as compared with those of the descriptive approach as being qualitative rather than quantitative, possessing rigour rather than precision and logical cogency rather than mathematical formulation.
