 1 Repeated measures designs differ from independent groups designs because independent variables have more conditions (levels) in the repeated measures design. A) True B) False 2 It is not necessary to use random assignment to control for individual differences variables in the repeated measures design. A) True B) False 3 Practice effects are the primary threat to the internal validity of repeated measures designs. A) True B) False 4 Two major advantages of the repeated measures design is that this design requires fewer research participants and it is more efficient than the independent groups design. A) True B) False 5 The "sensitivity" of an experiment refers to its ability to detect large effects of the independent variable. A) True B) False 6 Independent groups designs are less sensitive than repeated measures designs because there is typically more variability in responses between different people in conditions than there is variability within individuals. A) True B) False 7 Assessing the test-retest reliability of a questionnaire is the same as conducting a repeated measures design experiment. A) True B) False 8 Random assignment to conditions in the independent groups design is analogous to counterbalancing in the repeated measures design. A) True B) False 9 Practice effects must be balanced in the independent groups design and the repeated measures design. A) True B) False 10 The complete repeated measures design is used when individuals participate in each condition of the independent variable more than once. A) True B) False 11 Practice effects in the complete repeated measures design are counterbalanced using all possible orders or selected orders. A) True B) False 12 In ABBA counterbalancing a random order of conditions is presented twice. A) True B) False 13 In a complete repeated measures design practice effects are balanced within each individual. A) True B) False 14 In an incomplete repeated measures design each participant experiences only one level of the independent variable exactly once. A) True B) False 15 When there are four or fewer conditions of an independent variable in an incomplete repeated measures design it is best to use all possible orders for presenting the conditions. A) True B) False 16 Data analysis for the complete repeated measures design requires the additional step of computing a summary score for participants' performance in each condition of the experiment. A) True B) False 17 The logic of inferential statistics for the repeated measures design differs from the logic used for independent groups designs. A) True B) False 18 Differential transfer occurs when the effects of one condition persist to influence participants' experience of subsequent conditions in the experiment. A) True B) False 19 Similar to practice effects, the problem of differential transfer in a repeated measures experiment is controlled through counterbalancing. A) True B) False 20 The effects of differential transfer can be eliminated in a repeated measures design but not in a random groups design. A) True B) False 21 A repeated measures design is an experiment in which individuals participate in each condition of the independent variable. A) True B) False 22 The effects of individual differences variables in the repeated measures design are averaged across conditions using counterbalancing. A) True B) False 23 Practice effects are eliminated in the repeated measures design through counterbalancing. A) True B) False 24 A disadvantage of the repeated measures design is that it is less sensitive than the independent groups design. A) True B) False 25 The less the variability in participants' responses within the conditions of an experiment, the greater the sensitivity of the experiment. A) True B) False 26 A repeated measures design differs from a longitudinal survey design because an independent variable is manipulated in a repeated measures design but typically not in a longitudinal survey. A) True B) False 27 A major problem in repeated measures design is due to the confounding of individual differences variables with the levels of the independent variable. A) True B) False 28 Both independent groups designs and repeated measures designs require that potential confounding variables be controlled through balancing; however, the nature of the confounding variables differs. A) True B) False 29 "Practice effects" refer to the potential problem that participants' performance always improves across the conditions of a repeated measures design. A) True B) False 30 In an incomplete repeated measures design, participants experience some of the conditions of the independent variable, but not all of them. A) True B) False 31 Block randomization is the preferred counterbalancing technique in the complete repeated measures design when anticipation effects are likely or practice effects are nonlinear. A) True B) False 32 "Linear practice effects" refers to the idea that each presentation of a condition in the experiment adds the same amount of practice. A) True B) False 33 In an incomplete repeated measures design practice effects are balanced for each participant. A) True B) False 34 The rule for balancing practice effects in an incomplete repeated measures design is that each condition of the independent variable must be presented in each ordinal position (1st, 2nd, etc.) equally often. A) True B) False 35 In an incomplete repeated measures design that uses all possible orders of the conditions, each participant experiences all of the possible orders. A) True B) False 36 Random starting order with rotation and Latin Square are two methods for creating selected orders of conditions of the independent variable in an incomplete repeated measures design. A) True B) False 37 An advantage of the "random starting order with rotation" method for selecting orders of presentation is that each condition precedes and follows every other condition equally often. A) True B) False 38 The error variation in the statistics for a repeated measures design is generally less than the error variation for the same variables when manipulated in an independent groups design. A) True B) False 39 A researcher who tests the effects of alcohol vs. no-alcohol conditions in a repeated measures design should be aware of the problem of differential transfer. A) True B) False 40 One way to determine whether differential transfer is a problem in a repeated measures design is to replicate the repeated measures design to see if the same results are observed. A) True B) False
