A03

• A03; based on well controlled research

  • lab with high internal val and control of evs and cvs
  • allows for standardisation,replication,reliability
  • therefore, takes reductionist approach as breaks down behaviour into simple components allowing cause and effect relationships
  • thus has scientific credibility and covers one aim of science
  • however lacks mundane realism,ecological validility
• A03; operant conditioning has real world application

  • used in some psychiatric hospitals in the form of token economy(extend)
  • increases QOL,return to work, benefit the economy
  • shows approach has high external validity and widespread credibility
• A03; ethical concerns with animals

  • treated poorly, kept in harsh conditionins, starving
  • therefore CBA needs to take place
  • also cannot extrapolate findings due to different congnition and emotions however animals decrease demand characteristics
  • however studies cannot be carried out on humans so it still increases knowledge to an extent
