    • Maplesden Noakes AS Psychology Key Words Test 2013 Name: _____________________________ Target Grade Score Grade Distance from target grade Sub-topics Which questions? Score on this sub-topic Aims, hypotheses and variables 3, 4 & 6 Validity and Reliability 10, 15, 17, 20, 23, 27 Sampling 1, 2, 11, 12 & 13 Research design 16, 18, 19, 26 Experiments 7, 14, 15, 21 Observations 8, 22, 23 Self-report techniques 5, 10, 25 Comments and target
    • 1. A researcher put an advert in a newspaper asking for participants for her research. Participants were asked to e-mail her if they wanted to take part. What type of sample is this? a. Random Sample b. Volunteer Sample c. Opportunity Sample 2. A researcher is conducting research into how stress affects reaction times. Her sample consists of 13 men and 2 women, and because there are significantly more men this means her sample isn’t _____________________________ of the target population which consist of a more even number of men and women. 3. A group of sixth form students want to investigate whether putting signs up in the common room asking people to work in silence reduces the level of noise. For one week they measure the noise level in the common room without a sign up, and for a second week they out up signs and then measure the noise level again. The __________________________________ in their research is whether or not there is a sign up and the __________________________________ is the level of noise in the common room. 4. An ____________ is a general statement about what a piece of research is investigating. 5. A researcher is investigating opinions on the government and decides to use an interview to collect data. He expects that older participants will have more negative opinions on the government than younger participants. He decides to get another researcher who is unaware of the hypothesis to conduct to the interviews. He has done this to reduce _________________________________. 6. Before conducting a piece of research the researcher will write a _________________________, stating what the researcher is expecting the results to be. This will either be a _____________________________________________ or a __________________________________________________. 7. An experimenter is conducting a study into how stress affects a person’s eye witness testimony. They set up a situation where a man robs a bank. Customers at the bank are then asked to choose the man who robbed the bank from a line-up of 6 photographs. Participants are then asked to rate their stress levels during the incident on a scale of 1-10. This is an example of what type of research method? a. A correlation b. A field experiment
    • c. An observation 8. When the main researcher is conducting an observation there is a possibility of ___________________ _________________ occurring due to the researcher wanting to finding support for their hypothesis. 9. As a research method the observation is high in ____________________/____________________ _________________ since we are directly observing how people observe in their natural environment. 10. The extent to which two interviewers produce the same results from an interview is known as ____________________________________________________. 11. Which sampling method gives every member of the target population an equal chance of being selected? Answer: ___________________________________________ 12. A university lecturer wants to conduct a study into how sleep affects memory. He selects participants by asking his psychology class to participate in his research. This is known as an _____________________________________________. 13. If a researcher has a very small sample of people for their research it will be difficult to ____________________________________ result to the whole target population. 14. A researcher wants to see how having experienced an earthquake affects the probability of developing stress-related illnesses (e.g. heart disease). She compares a group of people who have experienced an earthquake, and a control group who have not experienced an earthquake. This an example of what research method? Answer: _________________________________________ 15. A field experiment is high in ________________________/_______________________ _______________. This is because it is conducted in a natural environment. However, because it is conducted in a natural environment there are a lot of __________________________________________ which are difficult for the researcher to control. This will lower the ______________________________________ of the research. 16. A researcher is conducting an experiment into music and memory. She has 60 participants complete a memory task in silence and again listening to music. To eliminate _____________________________
    • the researcher decides to use a technique known as _________________________________. 30 of her participants completed the task with music then in silence, while the other 30 complete the task in silence then listening to music. 17. A researcher was conducting a piece of research into intelligence and reading speed. To measure intelligence the researcher created an IQ test. However when he began analysing the result he discovered that some questions on the IQ test were actually measuring memory instead of intelligence. This means the research will be low in _________________________________________. 18. A researcher is investigating how music affects problem solving skills. Participants are given a rubix cube to complete and the time taken to complete it is measured. In condition one the participants are in a room where the radio is being played, and in condition two the participants complete the task in silence. The researcher finds the participants are significantly quicker when working in silence. However, a second researcher points out that there may have been ___________________________. Specifically the researcher points out that there may have been ____________________________ since participants completed exactly the same task in condition one and two meaning they may just been better in condition two since they have done the task before. 19. When conducting an experiment a ________________________ or a _________________________ design are preferable because they eliminate any ________________________________. This is because participants in each condition are similar in some way. 20. A researcher gives his participants a questionnaire to measure the personality trait extroversion. He decides to ask them to complete the questionnaire today and again once a week for the next 3 weeks. The researcher has decided to do this to test the …………… a. Internal validity b. Internal reliability c. External reliability 21. A researcher has decided to use a ________________________________ as the research method for her experiment. When asked by a colleague why she wasn’t using a ____________________________ the researcher replied “because I can control all extraneous variables using my method, and therefore my research will be higher in internal validity than the method you have suggested” 22. A group of students wanted to conduct an observation to see whether boys and girls behave differently at lunch time. However, before they began the observation one student asked what
    • behaviour she was meant to be looking for. The psychology student in the group suddenly remembered her psychology lesson on observations and said “we need to decide on a set of __________________________________________ so we are all looking for the same thing.”. 23. By comparing the results of an observation recorded from 2 or more observers we are checking the _________________________________________ of the observation. 24. If an observer is tallying behaviours in not a completely honest way the results will be affected by _______________________________. This may be because the researcher wants to find support for his/her hypothesis. 25. A researcher wants to find out about views on minority groups in the workplace. He thinks that men and women might have different views, with women feeling more positive about minority groups. He gives out a questionnaire to employees at a local company; however he finds there is absolutely no difference. Just as he is about to throw out the questionnaires a colleague stops him and says “perhaps you should try using a different research method and you might find a difference, the results of your questionnaire might have been affected by __________________________________.” 26. A researcher wants to use an ______________________________________ design for his experiment. However, another researcher asks him how he is going to control participant variables when using this design. The researcher tells his colleague that by randomly allocating participants to the different conditions the variation amongst participants is more likely to split across the conditions. 27. A researcher is conducting an experiment into how music affects memory. He gives his participants a list of words to learn while there is music playing in the background. After the experiment the researcher overhears a conversation between two participants. One participants says she found it really hard to learn the words with the music playing the background, the other replies the she guessed they weren’t meant to be able to remember the words with music playing so didn’t even bother to try. This is an example of ______________________________________________.
