41)ABA designs are also known as A)alphabetic designs. B)Latin square designs. C)reversal designs. D)multiple baseline designs. 42)In reversal designs, the effects of a manipulation are demonstrated by A)measuring the independent variable at three or four points in time. B)measuring the independent variable during the no-treatment baseline period. C)reversing the order of presentation of experimental stimuli. D)measuring the dependent variable at three or four points in time. 43)In an ABA reversal design, the term “reversal” refers to A)the sequential reversal of levels of treatment. B)reversing the order of presentation of stimuli. C)controlling for sequence effects. D)switching the independent variable with the dependent variable. 44)In ABA designs, the effects of the independent variable on the dependent variable are demonstrated if A)the level of the dependent variable stays the same in spite of any manipulation. B)the behaviour changes in the predicted direction whenever the conditions are reversed. C)the level of the dependent variable changes even though there is no independent variable being manipulated. D)the time graph shows some fluctuations. 45)The ABA reversal design is, according to the textbook example, an ideal one for studying A)the effect of seatbelt legislation. B)the effect of reducing the speed limit on accidents. C)treatment of self-stimulation behaviour in a mentally retarded child. D)a new medication used to treat serious depression. 46)In the hypothetical example given in the text of the use of an ABA reversal design to reduce Betty’s self-stimulatory behaviour, the independent variable is ________ and the dependent variable is ________. A)the self-stimulatory behaviour; teacher’s attention B)the baseline behaviour; the treatment C)the baseline; the intervention D)teacher’s attention; the self-stimulatory behaviour 47)In the hypothetical example given in the text of the use of an ABA reversal design to reduce self-stimulatory behaviour, the dependent variable is operationally defined as A)the number of minutes per day in which the self-stimulatory behaviour occurs. B)the intervention. C)the baseline. D)the sequential reversal of treatment levels A and B. 48)Reversal designs are also called A)pretest-posttest designs. B)randomized time-series designs. C)multiple baseline designs. D)ABA designs. 49)The second A in an ABA design refers to A)the reversal to the no-treatment condition. B)the absolute minimum number of responses. C)the archaic principle. D)the treatment condition. 50)In the example of an ABA design in which a teacher wanted to reduce a child’s self-stimulatory behaviour, the independent variable was A)the number of times the child hit herself. B)the number of days it took to reduce the self-stimulatory behaviour. C)the attention given to the child when she engaged in self-stimulatory behaviour. D)the psychologist’s presence in the classroom. Â
