3770 – reviewPremack principle: high frequency behaviors can reinforce low frequency behaviors Backward chaining: the teaching of a behavior chain begins with the last behavior of the sequence and ends with the first. Behavioral shaping: the differential reinforcement of successive approximations to a terminal behaviorChaining: the name for procedures linking behaviors in a sequence. Concept formation: generalization within a class of stimuli and discrimination between classes of stimuli.Behavior chain: a sequence of responses in which one response produces the conditions necessary to the next. Differential reinforcement: reinforcement which is contingent upon the occurrence of specific response properties (specific stimulus properties)Discriminative stimulus: a stimulus in the presence of which a response is reinforced Forward chaining: chain begins with first behavior and ends with the lastOpportunity to respond: presentation of the stimulus conditions constituting the occasion for the target responseDiscrimination: control by a particular stimulus classResponse differentiation: changes in the properties of the response (topography, duration, location…)Stimulus control: behavior under the differential control of an antecedent stimulusSuccessive approximation: any behavior that is an intermediate value of the terminal behaviorTask analysis: breaking a complex skill into small unitsTotal task presentation: the whole chain is trained from beginning to end in every presentationErrorless learning: the transfer of stimulus control with minimal error production.Fading: gradual change of the intensity of a promptGraduated guidance: the teacher provides a physical prompt only when needed, and it is faded immediately after a correctLeast-to-most prompting: greater degrees of assistance over timeMost-to-least prompting: starts with complete assistance and gradually reducesStimulus shaping: gradual change of topography of prompt towards the criterion stimulus controlPreattending skills: behaviors that result in the appropriate contact the discriminatinve stimulusSimultaneous discrimination: a procedure that consists of presentation of SD and S-deltasResponse prompts: supplementary stimuli to guide the student to emit the correct response Stimulus prompts: supplementary… brings student under correct stimulus controlSuccessive discrimination: a procedure that consists of the sequential presentation of the SD and other stimuli. Time delay: delaying the presentation of the prompt after the natural stimulus is presented. Transfer of stimulus control: the change of stimulus control from supplementary to
