  10. 5. June 2014 Psychologists use a range of methods to collect their data including experiments and observations. Behaviourists believe that the subject matter of psychology should be observable behaviour and experiments can sometimes include the use of observational techniques. The presence of others can be studied experimentally by measuring what participants are doing rather than what they are thinking.

  11. You must choose one of the options: • The effect of presence of others on musical performance. • The effect of presence of others on sport performance. • The effect of the presence of others on mathematical skill. • The effect of the presence of others on acts of kindness. • The effect of the presence of others on acts of aggressive behaviour. • The effect of the presence of others on acts of food choices. • The effect of the presence of others on face recognition. • You must use an independent measure design and plan to collect data which measures observable behaviour. It must be a practical project that could be conducted.

  12. Questions (Total Mark 40) • State the null hypothesis for your practical project. (3) • Describe the method you would use to conduct your practical project. (19) • Outline one advantage of using the experimental method in your practical project. (3) • Explain one strength of using the independent measure design in your practical project. (3) • Explain one weakness of using the independent measures design in your practical project. (3) • State and appropriate inferential statistical test to analyse the data that would be collected in your practical project. Give reasons for your choice. (3) • Briefly discuss one practical issue in relation to your practical project. (3) • Suggest an alternative way of manipulating the independent variable in your practical project. (3)

  13. Section B

  14. Section B • Briefly outline the observational method in psychology. (4) • Describe two pieces of psychological research that uses the observational method. (8) • Discuss the strengths and limitations of conducting research using the observational method. (12) • Compare the observational method with the case study method. (8) • Discuss the extent to which the observational method is scientific. (8)

  24. Are these significant? Don’t forget, if they are significant, you reject your null hypothesis and accept the alternative one; if they aren’t, you retain the null and reject the alternative.

  25. Are these significant? Don’t forget, if they are significant, you reject your null hypothesis and accept the alternative one; if they aren’t, you retain the null and reject the alternative.
