Pass the big ABA exam Chapter 5: Experimental Design

Pass the big ABA exam Chapter 5: Experimental Design Chapter 5: Alternating treatments design with baseline and final best treatment phase - ANSWER Most widely used alternating treatments design Chapter 5: Alternating treatments design with baseline - ANSWER Whenever possible, baseline should be conducted as it shows change produced by each IV Chapter 5: Alternating treatments design single phase without baseline - ANSWER Does not require an initial baseline Chapter 5: Alternating treatment design (aka concurrent schedules design, multi-element baseline design, multiple schedules design) - ANSWER An experimental design in which 2 or more conditions are presented in rapidly alternating succession independent of the level of responding & the differential effects on the target behavior are noted; compares 2 IVs to one another to determine efficacy Chapter 5: NCR reversal design - ANSWER NCR serves as a control condition instead of BL where no reinforcement is provided Chapter 5: Multiple treatment reversal - ANSWER A type of design that compares 2 or more IVs to baseline and/or to one another Chapter 5: B-A-B reversal - ANSWER 3 phase reversal design: 1 -BL, 2 -IV removed, 3 -IV reintroduced Weaker than A-B-A design because it doesn't allow for assessment of the effects of IV during BL Chapter 5: Reversal - ANSWER Any experimental design in which the researcher reverses responding to a level obtained in a previous condition; alternation between BL and intervention; treatment variable may be reversed; term encompasses both reversal and withdrawals of the IV Chapter 5: Changing criterion design - ANSWER A design in which an initial BL phase is followed by a series of treatment phases consisting of successive & gradually changing criteria for reinforcement or punishment; only one behavior Chapter 5: Delayed multiple baseline design - ANSWER Initial BL & intervention begin & subsequent BLs are added in a delayed or staggered fashion; effective when: reversal isn't possible, limited resources available for a full-scale design and when a new bx, subject or setting becomes available
