- Cognitive Psychology
- Assumption
- Our behaviour is mainly explainable in terms of our cognitive processes (input, throughput and output)
- Uses the computer analogy
- Strengths
- Opens up the "black box" which was disregarded by behavioural psychologists in the 19th century
- Usually uses laboratory experiments making the data highly repeatable and therefore reliable
- Good for helping psychology with being regarded as a science
- Important practical applications
- Loftus and Palmer- questioned eye witness testimonies being only evidence in a conviction
- Weaknesses
- The computer analogy breaks down- human decision making is also effected by instinct and emotion, this is unlike a computer.
- Many conducted in a laboratory
- Lacks Ecological validity
- Questionable validity of some measurement methods
- Very difficult to measure or truly know some processes such as thought (throughput)
- Reliant on reliability of the participants- they could not be truthful about their throughput (if self report about thought)
- Associated studies
- Savage-Rumbaugh (1986)
- Loftus and Palmer (1974)
- Baron-Cohen (1997)
- Assumption
