  • 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)
