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. Inactive substance or condition disguised as a treatment substance or condition - used to form control group






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






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






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. Tell you the average extent to which scores were different from the mean - if average standard deviation is large - then scores were highly dispersed






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






7. Capable of showing order and pacing because equal spaces lie between the values - do not include real zero - ex: temperature






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






9. Mean (standard error of mean) - median mode; normal and platykuric: equal; positively skewed: mode - med - mean; negatively skewed: mean - med - mode; bimodal: equal mean and med - 2 modes






10. Empirical-keying or criterion-keying approach; to determine of subject is like a particular group or not






11. How the score are spread out overall






12. For children 4-6






13. Subjects alter behaviour because they are being observed






14. Comparing an individual'S performance on 2 halves of the same test to reveal internal consistency; internal consistency can be increased by item analysis






15. Not to diagnose depression but assess severity of depressive symptoms; used by researcher or clinician to track course of depressive symptoms






16. If it is significant - same finding can be generalized to the population - use test of significant to reject null hypothesis






17. Not IQ - It is unlikely IQ captures all facets of it






18. Allows own answer: expression of conflicts - needs - impulses; content interpreted by administrator - some more objective than others; Rorschach Inkblot Test - Thematic Apperception Test - Rosenzweig Picture-Frustration (P-F) Study - Word Association






19. Process in testing concurrent validity






20. Tests the same person at multiple time points and looks at changes within that person






21. Personality measure for 'normal' / less clinical groups than MMPI - by Harrison Gough






22. Whether content covers a good sample of construct being measured






23. Most commonly used for adults 16+ - organized by subtests with subscales and identify problem areas; current is WAIS-IV






24. Used most commonly on standardized test






25. Similar to word association - finish incomplete sentences






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






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






28. Use correlation coefficients in order to predict one variable y from another variable x - let you define a line on graph that describes the relationship between x and y - when the least-square line or regression line is fit to the data - basically: u






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






30. Different subjects of different ages are compared - faster - easier






31. Sorting cards into a normal distribution; each has a different statement on it about personality; to one end is 'least like self' - other is 'most like self' - and middle is neutral; factor analysis to reduce viewpoints into a few factors






32. 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






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






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






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






36. Notable for cross-cultural application and simple directions - to make the best picture of a man - scored based on detail and accuracy - not artistic talent






37. The approach to construct assessment instruments - involves selection of items that can discriminate between various groups; responses determine if he is like a particular group or not; e.g. Strong-Campbell Interest Inventory






38. Knowing a fact






39. When subject behave differently just because they thing that they have received the treatment substance or condition






40. When subjects that drop out are different than those that remain; no longer random






41. Measure arousal of sympathetic nervous system - stimulated by lying and anxiety






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






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






44. Interest in the effect of independent variable on the dependent variable - often manipulated by applying it in experimental or treatment condition and withholding it from control condition






45. Like a histogram except that the vertical bars do not touch - various columns are separated by space






46. Whether test really taps abstract concept being measured






47. Step beyond correlations; allows not only identification of relationship between 2 variables - also make predictions






48. Not simple and linear - looks like a curved line - ex: arousal and perfomance - high A --> low P - Low A --> low P - medium A --> high P






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






50. 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
