2 In the study by Andrade, two groups were compared, a doodling condition and a control condition. Each participant produced a memory score. (a) Explain the purpose of a ‘control condition’, using an example from this study. ................................................................................................................................................... ................................................................................................................................................... ................................................................................................................................................... ...............................................................................................................................................[2] (b) Name a suitable graph to display the mean memory scores for the doodling condition and the control condition. ...............................................................................................................................................[1]

Mark scheme: 2(a) Explain the purpose of a ‘control condition’, using an example from this 2 study. 1 mark for explanation of the purpose of a control condition 1 mark for identification of the control condition in Andrade • A control condition is the absence of the IV, in this case the absence of (a cue for) doodling to compare to the experimental condition to look for a difference / to see if the IV is the cause of a difference = 1 mark (explanation) • The control condition was the ‘no doodling’ group (who were not given a special sheet or asked to ‘shade circles and squares’) = 1 mark (example) • Andrade used the control group as a baseline to compare the doodling group’s monitoring/recall scores = 1 mark (example) 2(b) Name a suitable graph to display the mean memory scores for the 1 doodling condition and the control condition. 1 mark for bar chart / bar graph

Mark scheme: 3(a) Outline what is meant by a ‘case study’. 2 Both marks are for outlining the term, examples only gain marks if they are part of the definition. 1st mark for either detailed or one instance/person 2nd mark for any of: detailed one instance/person of a rare / unusual condition may be longitudinal (can use) several different data collection methods (can use) triangulation • an in-depth study of a single participant = 2 marks • a very descriptive study of one unit = 2 marks 3(b) Suggest one disadvantage of using a case study. 2 Both marks are for one disadvantage. Points may be linked but do not have to be. • one person is studied and they may be rare/unique/unusual = 1 mark • so researchers are less likely to be able to generalise to the wider population / less representative = 2nd mark • reliability may be a problem because the researcher may be subjective and vary their interpretation = 2 marks • the researcher may be get to know the participant well (making their interpretation / data collection) subjective = 1st mark • which would make the data invalid = 2nd mark

4 In the study by Pepperberg (parrot learning), the data collected was the parrot’s speech. Alternatively, the parrot’s actions in response to instructions, such as ‘peck yellow square’ could have been observed.

Mark scheme: 4(a) Suggest why observing the parrot’s actions might have been a better way 2 to collect data than using the parrot’s speech. Both marks are for the suggestion. 1 mark for identifying an advantage. 2nd mark for detail. • An action may be much more obvious / speech could be misheard/ misunderstood (=1 mark) • So the observers would make fewer errors (=1 mark for detail) • this would make observing actions a more valid/reliable measure (both are correct) (=1 mark for detail) 4(b) Suggest why observing the parrot’s actions might not have been a better 2 way to collect data than using the parrot’s speech. Both marks are for the suggestion. 1 mark for identifying a disadvantage. 2nd mark for detail. • An action requires an additional instruction / the instruction ‘peck’ (= 1 mark) • the parrot may not understand this instruction (= 1 mark for detail) • this would make the parrot appear not to understand the concept (= 1 mark for detail) • which would be incorrect / would lower validity (= 1 mark for detail)

Mark scheme: 6 Describe what researchers can and cannot learn from correlational 6 studies, using any examples. Award 1 mark per idea. Up to max 4 marks for all one side, e.g. ‘can tell us’. Award max 3 marks for examples. From correlations we can learn about: • relationships/links between variables (accept can be negative or positive if no definitions); (1 for definition) • whether the two variables are positively correlated i.e. both increase together • for example Piliavin et al. found that as group size increased the likelihood of helping also increased • or negatively correlated, i.e. as one increases the other decreases • for example, Piliavin et al. expected to find that as group size increased the likelihood of helping would decrease • so they can guide ideas for (future) experimental work • can study variables which cannot practically be manipulated, such as activity levels in dreams • can study variables which cannot ethically be manipulated, such as phobia strength From correlations we cannot learn about: • causal relationships between the variables being tested • i.e. whether one causes the other to change • or whether they are both dependent on a third factor • e.g. Dement and Kleitman could not be certain whether longer REM caused longer dreams or longer dreams caused longer REM periods.

Mark scheme: 7(a) Explain one ethical issue Dr Kwan should consider in choosing which 2 species to test. You may use an example in your answer. 1 mark for linking issue to animal species e.g. social / solitary 2nd mark for detail about potential ethical problems (this may include a relevant example) • He would have to choose a species that would cope with both social company; and isolation = 2 marks • A solitary animal would be unsuitable; as it would be distressed being in the experiment when it had to be with another one = 2 marks • Dogs are unsuitable because they are social; and could be distressed by the social isolation = 2 mark 7(b) Dr Kwan has considered testing whether the animals can help each other 1 to avoid pain. Explain why this might be an unethical procedure. 1 mark for a comment based on the experiment related to pain/distress. • The animal that needed help would have to be in pain, which is unethical = 1 mark • The animal that was supposed to help might be distressed if it could not stop the experimental animal’s pain, which would be unethical = 1 mark 7(c) Dr Kwan should use as few animals as possible, for ethical reasons. 1 State why it would also be important that Dr Kwan uses a big enough sample. 1 mark for idea that small samples may not be representative • If the sample is too small the findings may not be representative of the species / the results may not generalise to the rest of the species = 1 mark 7(d) Dr Kwan has developed behavioural categories for observing the 3 animals. However, he thinks that another researcher should conduct the observations rather than him. Explain why this is a good idea. 1 mark for correct use of subjective / objective 1 mark for explaining idea of avoiding subjectivity / being objective 1 mark for detail, e.g. for the consequences if Dr Kwan did /did not record the data himself Max 2 marks if explanation not linked to study • Dr Kwan believes that the animals will help, so is biased • so he may not observe/record data in an objective way / he may be subjective in his data collection • this would tend to make his results fit his expectations • making the results invalid

Mark scheme: 8(a) Suggest two closed questions that Kieran could ask in a structured 2 questionnaire. 1 mark per relevant closed question with answer options X2 • Did you have a nice dream last night? yes/no (= 1 mark) • Rate how happy you felt today on a scale of 0-5 (0 = not happy, 5 = happy) (= 1 mark) 8(b) Explain one advantage of using closed questions. 2 Both marks are for the advantage. Award 1 mark for identifying an advantage. Award 2nd mark for detail. • They give objective data • so are reliable to interpret • They give numerical data / data that can be converted to numbers • so are easy to analyse 8(c) Outline what is meant by an ‘unstructured interview’. 2 1 mark for basic/partial explanation of term (e.g. of ‘interview’). 2nd mark for detail. • an interview is a real time / direct / face-to-face self report method (= 1 mark) • unstructured ones have no fixed questions (= 1 mark / 1 for detail) • so give the interviewer the freedom to adapt to what the participant says (= 1 mark / 1 for detail) • this means they can pursue interesting lines of questioning (= 1 mark for detail) 8(d) Suggest one open question that Kieran could ask during an unstructured 1 interview. 1 mark for a relevant open question • Describe how happy you have felt today. • If you had a dream last night, describe how nice it was. 8(e) Explain one advantage of using open questions. 2 Both marks are for the advantage. 1 mark for identifying an advantage. 2nd mark for detail. • They give participants freedom to express themselves • so are likely to be valid / more valid than closed questions (in this respect) • They give detailed / in-depth / qualitative data • so can reveal aspects in the results that could be overlooked if closed questions were used
