1. A behavior analyst is conducting a functional analysis of
a child's tantrums in a classroom setting. The analyst
manipulates four conditions: attention, demand, play, and
alone. In which condition does the analyst present attention
contingent on the occurrence of tantrums?
a) Attention
b) Demand
c) Play
d) Alone
*Answer: a) Attention. Rationale: In the attention
condition, the analyst provides attention to the child only
when he or she engages in tantrums, to test whether
attention is a maintaining reinforcer for the behavior.*
2. A teacher wants to increase the frequency of a student's

completing homework assignments and can exchange them
for preferred items or activities. What type of
reinforcement schedule is the teacher using?
a) Fixed ratio
b) Variable ratio
c) Fixed interval
d) Variable interval
*Answer: a) Fixed ratio. Rationale: In a fixed ratio
schedule, reinforcement is delivered after a fixed number
of responses. In this case, the student earns tokens for every
