Year 12 Psychology Verification Test Feedback

Question 5: One of the strengths of using secondary data from the internet for psychological research is that secondary sources will…

• A. Have satisfied ethical guidelines.

• B. have already been published and so the data is likely to be reliable and valid.

• C. provide large reserves of data and be representative of the general population.

• D. Provide access to volumes of data that the researcher may not be able to gather.

Question 6. What is a key aspect of controlled experiments?

• A. participants being exposed to only one condition of the experiment.

• B. aiming to ensure that the changes to the DV can be attributed to the IV rather than other variables.

• C. aiming to ensure that the changes to the IV can be attributed to the DV rather than other variables.

• D. utilising aspects of both between-subjects and within-subjects designs.

Question 8: Dr. Gaultieri is a psychologist interested in investigating whether studying psychology positively impacts the mental wellbeing of Australian teenagers. She recruited 54 Australian students from Everbrooke High School, where she works. The participants are divided into two groups – group 1 are students who do not study psychology and group 2 are students who do study psychology.

The experimental and control groups, respectively are…

• A. Group 2, Group 1

• B. Both group 1 and 2 are experimental groups

• C. Students who study psychology, Australian teenagers

• D. Group 1, Group 2

Question 10: The mean is a measure of central tendency often used in psychological research.

The mean can be a misleading representation of data if…

• A. the frequency of each score has not been calculated.

• B. the range of the scores is much greater than anticipated.

• C. it contains outliers, very small or large values in the scores that are not typical.

• D. there is not an equal number of scores whose values lie above and below its value.

Question 11: Professor Von Trapp is studying how the length of time that a stimulus is exposed to a participant affects the participant’s ability to recall the shape of the stimulus. She recruits 30 first-year university students, 15 male and 15 female. Each participant is presented with three sets of 10 shapes, which are exposed for: four seconds for the first set of 10 shapes, two seconds for the second set of 10 shapes and one second for the third set of 10 shapes. She then asks each participant to perform a memory recognition task for 50 different shapes, the 30 shapes previously seen and 20 distracters.

What research design was used in the professor’s study?

• A. Within subjects

• B. Between subjects

• C. Mixed design

• D. Correlational study

Question 15. Internal validity is best described as...

• A. the extent to which the results can be generalised to the population.

• B. the extent to which the results are due to the variables tested.

• C. the extent to which the results are consistent, dependent and stable.

• D. the extent to which alternative words or questions in a test generate similar results.

Question 17: Parminder compared the effects of consumption of alcohol on reaction times in people at various stages of life.

His stratified sample included participants aged 18 to 70 years. In the within subjects experiment, participants consumed one standard drink of alcohol at half-hourly intervals until they reached 0.10% blood alcohol concentration (BAC). Participants completed a series of computer-based tests for reaction times at BACs of 0.00%, 0.05% and 0.10%.

Additionally, once participants reached 0.10% BAC, Parminder asked all participants to write down on a lined piece of paper their immediate feelings, thoughts and memories, and to provide an estimate of how long they thought the tests ran for.

Which of the following accurately describes the two types of data Parminder was gathering during the testing period and after the last test?

• A. Subjective and qualitative

• B. Self-report and qualitative

• C. Objective and quantitative

• D. Quantitative and qualitative
