Tabby is a new bcba. She works with kindergarten students in a self-contained classroom at a public school as part of a clinic/home/school partnership between the aba clinic she works at. The preschoolers make her handprint thank you cards after she helps them with a cooking lesson that they enjoyed. Tabby turns to the teacher when they give her the cards and says, i am sorry but this would be a violation of bcba ethics code. The children start crying because they think she did not like the cards. What assimilation or separation strategy identified by knapp et al. , 2013 in the dark side of ethics is this an example of?.
