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

homework completion. The teacher decides to use a token

economy system, in which the student earns tokens for

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

homework assignment completed.*
