(subway Samaritans). 1 1 mark for aim • to investigate whether models affect altruism / to record the time it takes to help; • to test whether race affects helping / to count numbers helping black or white victims; • to compare helping by males and females; • to test whether ‘reason’ (ill/drunk) affects helping / to count numbers helping ill or drunk victims; • to test bystander effect / diffusion of responsibility

Mark scheme: 2 The study by Canli et al. (brain scans and emotions) raised ethical 4 issues of ‘right to withdraw’ and ‘protection from harm’. Explain why the study by Canli et al. raised these ethical issues. 1 mark for description + 1 mark for link x2 Right to withdraw: participants can leave a study at any time; for example if they are uncomfortable or distressed; and remove their data; without loss of payment; they should not be pressurised to continue; Right to withdraw may not be apparent if the participant is unaware that they are participating; and may suffer harm as a consequence; Canli et al.’s participants could not easily withdraw from the fMRI machine (as they are hard to get out of, e.g. if they became claustrophobic / because their heads were held still by the bite bar); (link) They were in a scanner; so couldn’t leave if they wanted; = 2 Protection from harm: a participant should not be exposed to any greater physical or psychological risk than would be expected in their day-to-day life; Canli et al. used an fMRI machine which carries risks for people whose bodies contain metal objects (and a participant might not have known this, so have been at risk); Canli et al. (deliberately) exposed participants to negative images, (which may have been distressing); (link) Canli et al. (apparently) did not use positive images afterwards to reverse the potential mood change; (link) They saw scary/unpleasant images; which could have cause harm; = 2

Mark scheme: 3 In the study by Laney et al. (false memory) random allocation was used. 3(a) Explain what is meant by ‘random allocation’, using this study as an 2 example. 1 mark for definition, 2nd mark for link Random allocation is a way to divide participants between levels of the independent variable such that any participant has an equal chance of being in any condition; (definition) Laney’s participants were in the ‘love’ (asparagus) / false memory group or the control group; (link) Laney’s participants were in the ‘love’ (asparagus) / false memory group or the control group by chance; 2 Participants are put in experimental or control group without bias = 0 (because could be stratified allocation) 3(b) Explain one strength of using random allocation in this study. 2 1 mark for strength, 1 mark for link Random allocation reduces the effect of confounding variables such as individual differences; (strength) The participants could have really loved asparagus or not (so would be spread between the groups); (link) The participants could have differed in gullibility to false memories (so would even across groups); (link)

Mark scheme: 4 In the study by Bandura et al. (aggression), children were shown a 2 room full of attractive toys to play with but were told they were for other children. Explain one of the two reasons Bandura et al. gave for doing this. 1 mark for a brief muddled explanation, 2 marks for a clear/detailed explanation From the paper: To make them angry/jealous/annoyed/aroused; So they were all equally likely to be aggressive; So they were likely to be aggressive in the next room; To ensure the children in the nonaggressive condition were feeling aggressive = 1 To ensure the low(ered) aggression children could be demonstrated in the nonaggressive condition = 2 To ensure they were likely to be aggressive/aroused = 1 To ensure performance of aggressive behaviour was not reduced by having watched aggression / catharsis = 2

Mark scheme: 6 Describe positive correlations and negative correlations, using any 6 examples. 1 mark for what a correlation is – looks for relationships / links between variables 1 mark for each definition, up to a maximum of 2, for each type of correlation 1 mark for each example that is linked to one issue, up to a maximum of 2, for each type of correlation. Examples can be from any studies (core studies, other studies, candidate’s own psychological studies). Max 4 if no examples Max 5 if only positive / only negative positive correlation: where two variables increase in the same direction / as one variable increases the other does too / directly proportional; has a coefficient between 0 and +1; (definition) Dement and Kleitman found a positive correlation between dream duration and dream narrative word count; Canli et al. found a left amygdala positive correlation: the greater the activation, the stronger the memory; Piliavin et al. proposed a positive correlation between number of bystanders ‘diffusion of responsibility’: the greater the number of bystanders, the greater the diffusion of responsibility; negative correlation: where two variables increase in opposite directions / as one variable increases the other decreases / inversely proportional; has a coefficient between 0 and –1; (definition) Baron-Cohen et al. found a negative/inverse correlation between eyes test score and AQ; Canli et al. found a negative correlation: the greater the emotional intensity (of the stimulus) the weaker the memory; Piliavin et al’s. proposed correlation between number of bystanders and ‘diffusion of responsibility’ can be described as a negative correlation: the more bystanders there are, the lower the speed/frequency of helping; Other ideas might be: Positive: time spent watching TV and aggression; Negative: hours of sleep and ability to concentrate; time spent in therapy and level of symptoms;

7 Jane is planning a laboratory experiment with two groups of participants. One group speaks one language fluently and the other group speaks two or more languages fluently. Jane thinks this may affect her dependent variable of how well they learn ‘nonsense’ words. These are words that read like real words but have no meaning. (a) Jane has two possible ways to measure her dependent variable: • by timing how quickly the participant can recall 10 nonsense words correctly • by counting the number of spelling errors made when recalling 10 nonsense words.

At first, Kofi is not certain what kinds of behaviours he will see. Credit reference to players or spectators throughout Q8. 8(a)(i) Explain why, at first, Kofi uses an unstructured observation. 2 1 mark for explanation 1 mark for link as he wouldn’t know which behaviour categories to use = 1 to decide which behaviours to choose (to observe next) = 1 to decide which aggressive behaviours to choose (to observe next) = 2 to decide which behaviours to choose for each sport = 2 Because he can record all the different behaviours = 1 (generic explanation) as he doesn’t know what aggressive behaviours he will see / will see in different sports; (link) 8(a)(ii) After watching different sports, Kofi can now use a structured 2 observation. Explain one strength of using a structured observation in Kofi’s study. 1 mark for strength 1 mark for link He would have an objective / reliable list of the different behaviours (in advance); (generic strength) this is important so he can concentrate on the aggression he sees and just tally so he observes better; (link) He would have a specific list of the different aggressive behaviours; (link) This is better as he can focus on observing and check listing (rather than writing details); (generic strength) The list of behaviours makes comparison easier; (generic strength) So he can compare (the same thing about) different sports; (link) 8(b) Kofi has decided to be a covert observer. 8(b)(i) Suggest one strength of being a covert observer in this study. 2 1 mark for strength 1 mark for link His role as an observer would not be apparent / he would be hidden/ disguised; (strength) and other spectators could limit their aggression (or exaggerate it) if they thought they were being observed (making the results less valid); (link) Participants won’t change behaviour / respond to demand characteristics / show social desirability; (strength) So their aggression levels will be normal; (link) 8(b)(ii) Suggest one weakness of being a covert observer in this study. 2 1 mark for weakness 1 mark for link Keeping your role hidden might make it hard to see; (weakness) So he may not be able to access all the aggression that is happening (making the results less valid); (link) No consent / participants are deceived / denied right to withdraw / potential harm; (weakness) The players / spectators unaware of observation / need right to avoid being observed / might be distressed if they find out they have been watched; (link)
