Research Methods Question Feedback

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.

  1. Research Methods Question Feedback THIS IS REALLY IMPORTANT STUFF

  2. 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

  3. 1a) What experimental design was used in this experiment? • Experimental design = • Matched Pairs, Independent groups, repeated measures • Independent groups • Therefore follows through to 1b)

  4. 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

  5. 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

  6. 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!!

  7. 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”

  8. 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

  9. 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

  10. 3a)i) • 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

  11. 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
