Reinforcer AssessmentYou may be required to perform a reinforcer assessment as part of yourschedule with your child. Typically, each child’s reinforcer bin is emptied whenthey leave school each day and a reinforcer assessment is conducted when theyarrive the following day. Reinforcer assessments consist of two components: 1)toy exchange, 2) preference assessment.The toy-exchange sessions take place in the playroom. This is done to obtainnew and more effective reinforcers. If possible, try to get sample stimuli fromall stimulus categories! (Visual, auditory, tactile, social…).Mini preference assessments take place in your booth. The purpose of apreference assessment is to determine which reinforcer is the most effective forthat child at that point in time. These should be conducted frequently, in betweenprocedures and sometimes even during procedures to make sure you are usingthe most reinforcing item with your child.These preference assessments are relatively easy to conduct. You will simplyshow the child two toys (or sometimes edibles) and ask him or her which onethey would like to play with. This should be repeated with different toys until thechild chooses one. If the child is not choosing a toy, you can play with it to try toentice them. Also, your playing with the toy when presenting it to the child mayincrease its reinforcing effectiveness and will increase your reinforcingeffectiveness.Additionally, for those children skilled in the Picture Exchange CommunicationSystem (see week 3) they can use icons to communicate which reinforcer theywould like to work for.
