BCBA practice

A behavior analyst records a toddler's tantrums for three weeks. She finds that tantrums are much more likely in the 15 minutes after the toddler's older sister receives a parent's attention. She has not changed anything in the home yet. Which goal of the science has her work reached so far?

• AControl, because a reliable relation between attention and tantrums was found
• BPrediction, because repeated observation shows that the two events reliably covary
• CDescription only, because no formal hypothesis has been written down yet
• DExplanation, because the sister's attention has been shown to cause the tantrums
