  • Cognitive Approach
    • Studies
      • Loftus and Palmer
        • Supports the approach because: the study is concerned with EWT and shows that memory is reconstructive, it shows that people reconstruct the past by fitting new info into their existing schema, and L&P showed this to be true.
      • Baron-Cohen
        • The approach could explain the difficulties experienced by individuals with autism, as they seem to have an impaired theory of mind, leaving them with social, communicative and imaginative abnormalities.
      • Savage-Rumbaugh
        • The approach considers methods of communication and language acquisition. The study found that the chimps where able to communicate with humans by using lexigrams, as they had learned to use symbols by observing.
    • Assumes that behaviour is caused by the way that we process information.
      • Preferred research method is controlled lab methods. As it allows you to focus on one variable to see how it affects a particular cognitive process.
      • It assumes the brain processes info similar to a computer: we input info through our senses, we process info (schemas), and we output info as our behaviour reflects our thoughts and intentions.
    • Strengths
      • Useful E.G. can use it in court as L&P showed that you can't rely on EWT
      • Scientific E.G. controlled lab method shows cause and effect (IV&DV)
    • Weakness
      • Reductionist, so as it ignores other factors the explanation for the behaviour is incomplete and low in validity.
      • Preferred research method is case study, this means that you normally cannot generalise the findings to the general public as the sample is not representative.
