| Abstract: | An extended series of functional analysis conditions were conducted to assess the operant function of aggressive behaviors emitted by a 33-year-old female with diagnoses of severe mental retardation and organic psychosis. Results from the primary test conditions were fairly undifferentiated, but response rates were elevated in the control condition. Independent-variable integrity data from the control condition indicated that aggressive behaviors were nearly always contiguous with the fixed-time delivery of experimenter attention. These results are discussed in the context of the current control condition functioning as a possible test for escape from social interaction. © 1998 John Wiley & Sons, Ltd. |
