Analysis
What is Video Modeling?“The occurrence of a behavior by an observer that is similar to the behavior shown by a model on a videotape”
-Nikopoulos & Keenan, 2004, p. 93
“A behavioral technique that uses videotapes…target behaviors in order to expand the learner’s capability to memorize, imitate, and generalize or adapt targeted behaviors”
-McCoy, & Hermansen,2007, p. 183
Effects of Video Modeling on Social Initiations by Children
with Autism (Nikopoulos & Keenan, 2004)
Nikopoulos Keenan
Effects of Video Modeling on Social Initiations by Children with Autism
(Nikopoulos & Keenan, 2004)
BackgroundChildren with autism make or accept fewer social
initiations and spend more time playing alone compared to their typically developing peers (Koegel, et al., 2001)
Video modeling is a method for promoting social skills (LeBlanc, et al., 2003)
PurposeExamine effects of video modeling on social
initiation and reciprocal play
Method (Nikopoulos & Keenan, 2004)
Participants 3 boys diagnosed with autism, 7-9 yrs old
Setting Video model one room Social initiations and play measured in
another room
Method (Nikopoulos & Keenan, 2004)
Stimulus Materials4 toys
Ball, trampoline, tambourines and a game All familiar with the toys
Video tape Typically developing peer (model) enters room with
the experimenter Experimenter sits in chair opposite the toys Child takes experimenter by hand and says “Lets
play” Both play with toy closest to the experimenter’s chair
for about 15 seconds
Method (Nikopoulos & Keenan, 2004)
Response Measurements
Social Initiation Child approaching the experimenter Emitting a vocal (“Let’s play”) or gestural (taking hand)
behavior Leading experimenter to the toy
Reciprocal Play Child engaged in appropriate reciprocal toy play with the
experimenter Session terminated by the participants (i.e. walk away,
say “all done”) or 5 min maximum
Latency to social initiation and total duration of reciprocal play were recorded
ProcedureMultiple baseline across subjects
BaselineChild and experimenter enter room Experimenter sits in seat across from toysAll toys presentRotation of toys located by the experimenter’s seat
Video modelingCondition B1: View of video before entering room
If social initiation occur within 25sec 3 consecutive sessions during each condition Condition C
If not Condition B2Condition B2: Simplified video. No play modelCondition C (generalization):
Removal of toy depicted in video and 2 other toys. See if respond with different toy then in video.
Follow up 1 and 3 months after final measurements
ResultsBaseline:
No social initiation or reciprocal playCondition B1:
1 child engaged in social initiation and reciprocal play
Condition B2: Other 2 children engaged in social initiation and
reciprocal playCondition C:
1 child engaged in social initiation and play (generalized)
Other 2 children social initiation only to play with modeled toy
Duration of reciprocal play increased for all More so in 3-month then 1-month follow up
Latencies to social initiation were low in follow-up
Implications
Social initiations as well as reciprocal play skills can be taught to children with autism using video modeling.
These skills appear to maintain for at least 3 months following teaching.
Possible Stimulus Control IssuesReinforcer Preference Assessment Not
Conducted
How were items chosen?Trained on one item, expected to generalize
skills to other 3 toys
How Well do the Participants Play with the Toys?
Jumping on a trampoline vs. gameAbility could reflect on EO to initiate and play
Possible Stimulus Control IssuesWhat Possibly Contributed to the Ability of
SDs to Gain Control Over Behavior?
Item’s proximity to the chairVideo model always chose one closest to
experimenter Positional prompt
Placement of ToysAlways in similar places
ExperimenterNo mention of generalization to other individuals
RoomNo other room used
Possible Stimulus Control Issues
Removal of Toys During Condition-C May have Contributed to the Increase in Play
Results
Perhaps create EO for the non-removed toyNo other toys to play with
Tweak-out: During initial baseline contains removal of all but one of the toys.
Other Considerations
Influences on the Effects of Video Modeling
Participants’ Imitation SkillsPrevious study by Nikopoulos and Keenan
(2003), state that social initiation was “dependent on imitation skills” (p. 102)
Preference of watching videosMany different ways to conduct
When/how reinforced?
Other Considerations
What is ‘Reinforcement’ for Desired Behaviors?
Toys?Social interaction?Is access to toys blocked with out social
interaction?What would you want the stimulus control
to be for child initiating and then playing with you?
