[FINA] A behаviоr аnаlyst runs a brief functiоnal analysis оf her young client Titania’s hitting behavior. After collecting data, hitting seems to occur at the highest rate during the demand condition of the functional analysis. The data in the functional analysis’s attention, alone, and control conditions all show an increase in hitting whenever they immediately follow a demand condition as the hitting often continues on into the following condition. However, whenever these conditions do not follow a demand condition, the rate of hitting is typically low in the attention, alone, and control conditions. Therefore, the data suggest the possibility of Titania’s hitting being maintained by “multiple functions.” The behavior analyst is rightfully concerned that these data are most likely being impacted by which confound?
