Research Methods Question Feedback. THIS IS REALLY IMPORTANT STUFF. General Feedback . YOU MUST LOOK AT THE MARKS ALLOCATED – is it a quick answer (1 mark) or does it need developing to a certain degree? IF YOU ONLY WRITE ON HALF THE LINES its probably not enough.

Research Methods Question Feedback

THIS IS REALLY IMPORTANT STUFF


General feedback
General Feedback

  • YOU MUST LOOK AT THE MARKS ALLOCATED – is it a quick answer (1 mark) or does it need developing to a certain degree?

  • IF YOU ONLY WRITE ON HALF THE LINES its probably not enough


1a what experimental design was used in this experiment
1a) What experimental design was used in this experiment?

  • Experimental design =

  • Matched Pairs, Independent groups, repeated measures

  • Independent groups

  • Therefore follows through to 1b)


1b explain one limitation of the design that was used in this experiment 2
1b) Explain one limitation of the design that was used in this experiment (2)

  • 1 mark for brief/muddled e.g. “individual differences“ or “needs more pts”

  • 2 marks e.g.

  • There may be differences between the groups as there are different pts in each condition. E.gpts in one group may have a better memory ability, affecting the results


1c explain what the results suggest about the effectiveness of the cognitive interview 2 marks
1c) Explain what the results suggest about the effectiveness of the cognitive interview (2 marks)

  • The graph shows that the cognitive interview is effective.

  • There were more correct statements made after the cognitive interview than after the traditional interview.

  • 1 mark for brief statement e.g. it’s effective

  • 2 marks for some elaboration with reference to correct/incorrect statements


1e) What is meant by the term investigator effects? Explain possible investigator effects in this study (4 marks)

  • 1 mark for brief or muddled “the researcher’s influence”

  • Maximum 2 marks for an accurate understanding of the term but no reference to this experiment

  • Can gain 4 marks if show full understanding without giving a definition

  • Occur when the researcher’s behaviour or characteristics influence the research in some way. This includes the way the presence of the researcher may influence the pts.

  • E.g. the psychologist may expect the cognitive interview to be most effective. This may unconsciously be communicated to the pt through mannerisms e.g. smiling/frowning. This would therefore affect the accuracy of the findings.

  • You must make it clear that the researcher is UNAWARE of it happening e.g. they wouldn’t ask leading questions on purpose! – especially a psychologist who specialises in memory research!!


2 a explain why this is an example of a natural experiment 2
2. a) Explain why this is an example of a natural experiment (2)

  • The IV is a naturally occurring variable

  • Ie not manipulated

  • Whether children attend nursery or a childminder’s is not manipulated by the researcher

  • “Answers referring only to research carried out in a real life situation should not receive credit”


b) Suggest one way in which the psychologist could have measured the children’s aggressive behaviour (2)

  • Name the METHOD

  • i.e. observation, questionnaire, interview

  • 2nd mark give detail as to how they would measure it

  • Observation would use…

  • Data collection grid/tally chart/ count up the number of aggression behaviours seen

  • Ask questions assessing how aggressive children are e.g. amount of times they hit, push, kick etc

  • Getting people to rate from 1 – 10 is not very clear


2c) Explain two ethical issues which the psychologist should have considered when carrying out this research (2 +2)

  • Identify the relevant issue – 1 mark

  • Elaborate – explain how it is an issue/what should be done/why 2nd mark

  • Must be relevant – unlikely that psychological harm will occur. WHY?

  • As nothing is being manipulated!

  • Informed consent – unable to make informed choice as under age 16

  • Confidentiality – parents may not want children to be identified so therefore should not use names/give pseudonyms


3a)i) have considered when carrying out this research (2 +2)

  • Mean

  • Total sensitivity score divided by number of caregivers

  • ii) explain one strength and one weakness of the measure of central tendency

  • 2 steps to your answer are needed!

  • It is a sensitive measure of data

  • This is because it makes use of all the values (therefore representative)

  • It is not useful if there are extreme values

  • This is because it uses all the data therefore these will make it misrepresentative

  • Don’t say this will may it unreliable - you mean not representative


B what do the standard deviations tell us about the data in the table 2 marks
b) What do the standard deviations tell us about the data in the table? (2 marks)

  • Standard deviation is a measure of...

  • Dispersion

  • The standard deviations tell us about variation in the data from the two groups (1)

  • It shows that the group receiving sensitivity training have more variation in their scores, compared to the group with no training (2nd)

  • Higher S.D. Suggests more variation in individual scores of sensitivity in this group

  • One point developed or two separate points can gain 2 marks.

  • IT DOES NOT SHOW that the sensitivity training is effective – the MEAN shows this

  • IT DOES NOT SHOW a correlation? - it’s an experiment with two conditions! A correlation is where you see if there is a link between two co-variables NOT IV and DV e.g. age and IQ would be two co-variables
