"Transitional objects" as establishing operations for thumb sucking: A case study.
Journal of Applied Behavior Analysis,
33, 507-509.
This study examines the effects of a "transitional
object" (surgical cloth) on the thumb sucking of a
3-year-old boy in two conditions: while sitting in the lap of his
physical therapist and while alone in his crib. Sucking occurred
when the cloth was present and did not occur when it was absent,
regardless of condition. These results are discussed in terms of
establishing operations, object attachment, and application.
