What is Video Modeling?
“The occurrence of a behavior by an
 observer that is similar to the
 behavior shown by a model on a
                  -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”

Effects of Video Modeling on Social
Initiations by Children with Autism

Effects of Video Modeling on Social
Initiations by Children with Autism
               (Nikopoulos & Keenan, 2004)

 Children 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)

 Examine effects of video modeling on social initiation and
  reciprocal play
             (Nikopoulos & Keenan, 2004)

 3 boys diagnosed with autism, 7-9 yrs old

 Video model one room
 Social initiations and play measured in another room
               (Nikopoulos & Keenan, 2004)

                     Stimulus Materials
 4 toys
     Ball, trampoline, tambourines and a game
     All familiar with the toys
 Video tape
     Typically developing peer (model) enters room with the
     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
                (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
   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
                  Multiple baseline across subjects
 Baseline
    Child and experimenter enter room
    Experimenter sits in seat across from toys
    All toys present
    Rotation of toys located by the experimenter’s seat
 Video modeling
    Condition B1: View of video before entering room
        If social initiation occur within 25sec 3 consecutive sessions during
         each condition  Condition C
        If not Condition B2
    Condition B2: Simplified video. No play model
    Condition 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
 Baseline:
    No social initiation or reciprocal play
 Condition B1:
    1 child engaged in social initiation and reciprocal play
 Condition B2:
    Other 2 children engaged in social initiation and reciprocal
 Condition C:
    1 child engaged in social initiation and play (generalized)
    Other 2 children social initiation only to play with modeled
 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
 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 Issues
Reinforcer 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. game
  Ability could reflect on EO to initiate and play
 Possible Stimulus Control Issues
What Possibly Contributed to the Ability of SDs to Gain
                Control Over Behavior?
 Item’s proximity to the chair
    Video model always chose one closest to experimenter
    Positional prompt
 Placement of Toys
    Always in similar places
 Experimenter
   No mention of generalization to other individuals
 Room
    No 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 toy
   No 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 Skills
   Previous study by Nikopoulos and Keenan (2003), state
    that social initiation was “dependent on imitation skills”
    (p. 102)
 Preference of watching videos
 Many 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?
