GRE Psychology: Measurement And Methodology

Subjects : gre, psychology
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. (Mental age/chronological age)/100 - Highest age = 16

2. Attitude change in response to feeling that options are limited; e.g. dislike experiment and intentionally behaving unnaturally - or being set on a certain flavour of ice cream as soon as told it is sold out






3. When subjects act in ways they think experimenter wants or expects






4. Mean of Americans is standardized to 100 - with SD 15 or 16 depending on test; correlates most with IQ of biological parents and socioeconomic status






5. Normal curve - negatively skewed distribution - positively sknewed distribution - bimodal distribution - platykuric distribution






6. Anything that is measured such as height or depression score on a depression scale






7. Measure mastery in a particular area (e.g. final exam)






8. Calculates how off the mean might be in either direction






9. Similar to T-test - but can measure more than 2 groups






10. Tests whether the means on one outcome or dependent variable are significantly different across groups - height or level of anxiety from anxiety scale






11. The degree to which an independent variable can predict a dependent variable






12. Measure the extent to which test measures what it intends to; concurrent - construct - content - face






13. The most frequently occurring value






14. Measured by the same individual taking the same test more than once






15. Tests the effects of two independent variables or treatment conditions at once






16. Frequency polygon (continuous variables) - histogram/ bar graph (discrete)






17. Critical of personality trait-theory and personality tests; felt situations (not traits) decide actions






18. Knowing how to do something






19. Analyses how a large group responded to each item on the measure; weeds out problematic questions with low discriminatory value; increases internal consistency






20. Tests whether at least 2 groups co-vary - can adjust for preexisting differences between groups






21. Intelligence in relation to performance; pioneered development of psychometrics - 'no intelligence is culture-free'






22. Originally used with free association techniques; word called out - subject says next word in mind






23. Aims to match demographic characteristics to population (i.e. 50% female - etc)






24. Subjects alter behaviour because they are being observed






25. Experimenter bias; researchers see what they want to see; minimized in double-blind






26. Every member of the population has an equal chance of being chosen for the sample






27. Fluid intelligence declines with old age while crystallized intelligence does not






28. Studying the same objects at different points in the lifespan and provides better - more valid results than most other methods - costly - time commitment






29. Have order - equal intervals and a real zero ex: age






30. Birth order vs. intelligence; the older - the more intelligent; the more children - the less intelligent; the greater spacing - the more intelligent






31. Might show how often different variables appear; nominal - ordinal - interval - ratio (real zero)






32. When subjects do and say what they think puts them in a favorable light -ex: reporting they are not racist even if they really are






33. For even number of values in the set - take the average of the two middle value






34. Created multitrait-multimethod technique to determine validity of tests






35. Mathematically combines and summarizes overall effects or findings for a topic; best known for consolidating effectiveness of psychotherapy - can calculate overall effect size or conclusion drawn from a collection of studies; needed when conflicting






36. Used when equivalent one cannot be isolated






37. Bell curve; larger the sample - greater chance of having a normal distribution






38. Combines longitudinal and cross-sectional approach






39. Rosenthal effect; researchers see what they want to see; minimized in double-blind






40. Describe what is seen in each of 10 inkblots; scoring is complex; validity questionable






41. Process in testing concurrent validity






42. Used when an experiment involves more than one independent variable - can separate the effects of different levels of different variables - can isolate main effects - can identify interaction effects - ex: studying effect of brain lesion on problem s






43. Whether scores on a new measure correlate with other measures known to test the same construct; cross validation process






44. How well a test measures a construct; multitrait-multimethod technique determines validity; internal - external: concurrent - construct - content - face






45. Internal-External Locus of Control Scale






46. Developed concept of IQ and first intelligence test (Binet Scale)






47. The effect that might result when a group is born and raised in a particular time period






48. Data that has been counted rather than measured - usually limited to whole or positive values - ex: group size - number of hospital visit - number of symptoms






49. How stable measure is; test-retest - split-half






50. Whether test items look like they measure the construct
