- cognitive psychology
- Overview
- information processing approach
- Information in --> processing --> information out
- Oversimplification?
- Assumption; brain processes information from the environment in a similar manner to a digital computer
- Hardware: physical system, i.e. the nervous system
- representational account: internal representation of external objects
- propositional representations: 'token' mental representations with semantic properties
- Indirect realism: access externa - reality through representation
- Software: mental processes
- Hardware: physical system, i.e. the nervous system
- information processing approach
- Information: amount of entropy (disorder) in a system (Shannon & Weaver, 1949)
- Cognitive processes: aim to process this surprise and filter out any noise
- Environmental information: processes by a variety of different processing systems (modularity)
- Includes visual processes, auditory, memory, and attention
- Discrete systems transform and store information collected from the environment
- A brief history
- Structuralist approach
- Wundt - theory of Introspection
- Limitations: cant be verified, different reports, can alter thought processes. Assumes mental processes are conscious
- Behaviourism
- Study of observable and measurable events
- Watson: need for scientific approach to psychology. Same foundations as other physical sciences
- All human behaviour can be explained in terms of the learned relationship through stimuli and response
- mental variables are unimportant - they are epiphenomenal
- Structuralist approach
