CH.16 Antecedent Control Procedures - ACP are also called antecedent manipulations,antecedent stimuliaremanipulated to evoke desirablebehaviors so thattheycan bedifferentiallyreinforced and todecrease undesirable behaviors that interferewiththe desirablebehaviors - ACP procedures involve manipulatingsomeaspect ofthephysicalor socialenvironmentto evoke a desiredresponse or to make acompeting,undesirablebehaviorlesslikely. - Presenting the Discriminative stimulus (sD) or Cues for the desired behavior: onereason tht a desirablebehaviormay not occur often isthtthediscriminativestimuli(sDs)for the behavior aren’t present in the person’senvironment.Ex:thesDfor eatinghealthfulfoodsis the presence of healthful foodsinthekitchen ortheperson’slunchbag.Ifunhealthyfoods aren’t present, the person willbe lesslikelytoeatsuchfoods. - Arranging Establishing Operations for the Desirable Behavior:EOisan envrnmntlevent or biological condition tht changesthevalueofa stimulusasareinforcer.When an EOis present, the behavior tht resultsinthtreinforcerevoked. - Decreasing response effort for the desirable behavior: arrangeantecedent conditions such that lesseffort isneededto engageinthebehavior.Behaviours tht requirelesseffort are more likelyto occur than are behaviorsthatrequiremore effort ifbothresultinfairly equal reinforcers - Presenting sD,EO,and decreasing responseeffort allevokeadesired response - One way to make a desirable behaviormorelikelyrooccur istomake undesirable competing behaviors lesslikely tooccur. - Removing the discriminative stimulus or cues for undesirable behaviors: onewayto decrease the likelihood of an undesirablebehavioristoremovetheantecedentconditions tht have stimulus ctrl over it.If thesDor cuesforan undesirablebehavioraren’t present,it isless likely tht the person willengageinthebehavior. - Presenting abolishing operations for undesirable behaviors: ifyoucan makethe outcome of the undesirable behaviorlessreinforcing,youwilllesslikelytoengagein the behavior and more likely to engage in thedesirablebehavior. You makeoutcome of the undesirable behavior lessreinforcingbypresenting anabolishingoperation(oreliminating an establishing operation) for thereinforcer.Ex:eat afullmealbeforeshoppingtoavoid buying junkfood - Increasing the response effort for undesirable behaviors: ifthecompetingbehaviorstke more effort, they are lesslikely tointerferewiththedesirablebehavior. - Research on AntecedentControlstrategies:manipulatediscriminativestimuli,manipulate response effort,andmanipulate motivatingoperations - If the person isengaging in the behaviorat leastoccasionally,antecedentctrlstrategies may be usedto mke it more likelythtthepersonwillengageinthebehaviorat the appropriate times.Differential reinforcement proceduresareused inconjunction with antecedentctrl procedures to maintainthebehavior. - If a person isengaging ina behavioralexcess,antecedent ctrlstrategiescan mkeit less likely tht thisundesirable behaviorwilloccur.Extinctionand differentialreinforcement are often used in conjunction with antecedent ctrlprocedurestodecreasebehavioralexcesses. - Conduct a functional assessment toanalyze3termcontingency(ABC)involved inevoking and maintainingthe desirable behaviorand undesirablebehaviorstounderstandthe situation and knowhow to use antecedent controlprocedures. - Antecedent ctrl strategi
