Three levels in Psychology:
- Descriptive: How decisions are made/observing behaviour/actions.
- Algorithm: What is the algorithm that the brain uses? ('Software')
- Hardware Implementation: How is the algorithm physically implemented? Associated with brain systems and their link to function.
Lots of work has been done aiming to determine the algorithms. However, research that has been done does not exactly determine a certain algorithm, but helps to exclude some possibilities.
Language
- Descriptive: How do people use language? How is language similar/different? How is language learned? What are the common problems/disorders of language?
- Algorithm: Rules that underline language - e.g. how can a computer understand/produce language?
- Hardware implementation: Parts of the brain that are involved with language. Neuronal function linked to the production and comprehension of language, writing poetry etc.
