problem behaviors. However, you have found that sitting the girl on her mom’s lap
while playing with toys seemed to be a reinforcer for appropriate behavior, so you
decide to implement an fixed-momentary DRO using mom’s attention and toys as the
reinforcer and an interval of 5 seconds. Which of the following would describe your
fixed-momentary DRO procedure most accurately?
a. Give the girl a specific appropriate response (e.g., say “mom”) that she should display
to gain access to mom and the toys. After 5 seconds expires, prompt her to engage in
this response. If she does it, she gets to play with mom and toys.
b. Set a timer for 5 seconds. When the timer dings, if the girl is not engaged in finger
picking, hair pulling, or face scratching, allow her to play with mom and toys. If she is
picking her fingers, pulling her hair, or scratching her face, do not allow her to play
with mom and toys.
c. Set a timer for 5 seconds. If she does not engage in finger picking, hair pulling, or
face scratching at any time during the 5 seconds, allow her to play with mom and toys.
Reset the timer contingent on finger picking, hair pulling, or face scratching.
d. Set a timer for 5 seconds. If she engages in finger picking, hair pulling, or face
scratching for 5 seconds, allow her to play with mom and toys.
Define event recording and give three examples of devices or procedures used to collect
event data.
