A component analysis of "stereotypy as reinforcement" for alternative behavior.
Journal of Applied Behavior Analysis,
33, 285-297.
Results from several studies have suggested that the opportunity
to engage in stereotypic behavior may function as reinforcement
for alternative, more socially desirable behaviors. However, the
procedural components of this intervention include several
distinct operations whose effects have not been analyzed
separately. While measuring the occurrence of stereotypy and an
alternative behavior (manipulation of leisure materials), we
exposed 3 participants to three or four components of a
"stereotypy as reinforcement" contingency: (a)
continuous access to materials, (b) prompts to manipulate
materials, (c) restricted access to stereotypy (i.e., response
blocking), and (d) access to stereotypy contingent on
manipulating the materials. Continuous access to materials and
prompting (a and b) produced negligible results. Restriction of
stereotypy (c) produced a large increase in the alternative
behavior of 2 participants, suggesting that response restriction
per se may occasion alternative behavior. However, contingent
access to stereotypy (d) was necessary to increase the 3rd
participant's object manipulation; this finding provided some
support for the use of stereotypy as reinforcement for
alternative behavior. Finally, when transfer of the effects of
intervention was assessed during periods in which active
intervention components were withdrawn, the alternative behavior
was maintained for 1 participant.
