inferences2) poor generality 3) based on improperevidence4) gathered in the support of the wrong questions5) wasting the field’s limited experimental resourcesThe goal would be to determine whether the innovation or established intervention results in better outcomesSome comparative studies are not of two different intervention but evaluate variations of the same intervention to develop and refineitThe goal of comparison to refine intervention studies is to identify the most powerful and efficient form of the interventionSometimes research focuses on whether two or more _interventionsare more or less effective give a couple contextual variablesContextual variables can be categorized on at least four dimensions.1) physical space and materials2) social structure3) temporal structure4) instructional characteristics
The goal of comparisons to understand interactions is to discern whether one intervention produces differential patterns of responding under varying conditions When a widely used intervention with little or no research support is suggested for use itis prudent to compare the effectsof the untested interventions with an intervention supported by researchMultitreatment InterferenceMultitreatment interference is the influence one experimental condition has on performance under another experimental condition Carryover effects are the influence of one experimental condition on performance under another condition due to the _nature of the initial conditions Sequence effects are the influenceof one condition on another due to the orderingof experimental conditionsRapid alternation effects are the effects on performancedue to rapidly changing (alternating) conditionsSeparation of Treatment IssueYou want to attribute the ultimateresults to one and only one interventionSeparation of treatments issues is when two or more interventions are applied to the same behavior, the ultimate levels of the behaviorcannot be attributed to only one intervention Multitreatment DesignsSequential introduction and withdrawal designs are flexible designs that allow for comparisonsbetween two treatments in addition to comparisonsbetween baseline and one treatment Variations of the ABABdesign developed to comparetreatments are called multitreatment designsMultitreatment designs are flexiblemaking them useful for a variety of important comparisonswith reversible behaviors Multitreatment designs can only be used when the dependentvariable of interest is a reversiblebehavior Alternating Treatment Design and Multi-element DesignAlternating treatment designs and the multi-element design are procedurally similarThe primary difference is that the ATDis used to compare interventions while the M-ED is used to assess factors that may be maintaining challenging behavior Adapted Alternating Treatments DesignThe adapted alternating treatments design (AATD) was developed to compare
