- Q14. Which of the following is not an advantage of field experiments?The studies have high ecological validityConsent is often not requiredthey are naturalisticThey are easily replicated30s
- Q21. Which of the following is not essential for a study to be a "true" experiment?Random allocation to conditionsExtraneous variables are controlledOne or more IVs are manipulated and the effect on the DV is measuredAll ethical considerations must be met30s
- Q3What is the key difference between a quasi-experiment and a "true experiment?"In a quasi experiment, participants have a trait that determines which condition they are in; in a true experiment, they are randomly allocated.a. Quasi experiments are cross-sectional; true experiments are longitudinal.Quasi experiments do not have controlled variables.Quasi experiments take place in naturalistic environments; true experiments take place in laboratories.30s
- Q4Which of the following is a null hypothesis for a study of the role of aerobic exercise on one's mood?16-year-old female participants who run on a treadmill for 30 minutes will score lower on a test for depressive symptoms than those that do not exercise.None of the 16-year-old female participants who run on a treadmill for 30 minutes will have depression, according to their scores on a test for depressive symptoms.16-year-old female participants who run on a treadmill for 30 minutes will score either higher or lower on a test for depressive symptoms than those that do not exercise.There will be no significant difference in the scores of on a test for depressive symptoms among 16-year-old female participants who run on a treadmill for 30 minutes and those that do not exercise.30s
- Q5Which of the following is the best explanation of the difference between a quasi-experiment and a natural experiment?Natural experiments randomly allocate participants to conditions; quasi-experiments do not.Quasi experiments are done in a lab; natural experiments are done in the field.All quasi experiments are natural experiments, but not all natural experiments are quasi experiments.The IV in both is not manipulated - but in a quasi experiment the IV is a trait of the individual and in a natural experiment it is an environmental factor.30s
- Q6A researcher carries out a study where the participants were asked to give electric shocks to a student in a study of learning. After the experiment, the researcher asks the participant why he thinks that he was willing to shock the student. He says that he "knew all along that this was fake." This is an example ofSocial desirability effectExpectancy effectOptimism biasScrew-you effect30s
- Q7A researcher does an experiment to see how people respond to an elderly person who is asking for help on public transportation. In some cases she is dressed very fashionably; in a second condition, she is dressed in a tattered old dress. Which type of experiment is this?A quasi experimentA longitudinal experimentA field experimentA natural experiment30s
- Q8If extraneous (confounding) variables are not well controlled, this may affectConstruct validityPopulation validityInternal validityEcological Validity30s
- Q9Participants completed a memory test in the presence of music, then they complete the same test without music. What is one limitation of this experimental design?Practice effectsExternal validityDemand characteristicsContent validity30s
- Q10In Loftus and Palmer, participants received a questionnaire with one of 5 verbs ("hit, smashed, contacted, bumped, collided". What type of experimental design was this?Matched PairsIndependent samplesRepeated measuresObservation30s
- Q11A limitation of an independent samples design is...time consumingDemand characteristics may be presentParticipant variability is not controlled forWe can directly compare the participant to themselves30s
- Q12A "matched pairs" design is when..Participants completed both conditions of the experimentParticipants in one condition are matched with participants in another condition on one or more characteristicsParticipants are randomly allocated to one condition.Participants only receive one condition30s
- Q13When we discuss external validity in quantitative research, we are..Discussing the extent to which the findings can be applied to time, location and other people.Discussing the extent to which researchers agree on the findings.Discussing the extent to which the findings reflect a real life situationDiscussing the extent to which we are measuring what we intend to measure30s
- Q14What is one limitation of using a volunteer sampling method in Psychological research?Volunteers may possess characteristics that make them different from non-volunteersVolunteers are representative of the target populationVolunteers might disclose the wrong information30s
- Q15A psychologist tests the hypothesis that eating chocolate while studying is detrimental to learning. The research is carried out by allocating participants one block of chocolate or no chocolate while studying in a lab, then completing a relevant test. Which of the following is NOT an extraneous variable that should be controlled?Questions on the testHow much chocolate they already eatTime of day the test is takenLearning ability of the participants30s
