Abstract

Objectives: The aim of the study was to evaluate the effectiveness of Time-out procedure
in reducing behaviours maintained by negative reinforcement. Method: At the beginning,
a functional analysis was conducted in order to identify functions of the stereotypical
behaviour (spitting) performed by a 6-year-old developmentally delayed child. Later on
the frequency of the target behaviour was measured before and during applying the
Time-out procedure and then again during a temporary withdrawal of the procedure and
after reapplying it. Results: The number of the target behaviour decreased while the
procedure was being applied whereas it increased after its withdrawal. Conclusion: A
procedure based on negative punishment can be effectively used to reduce behaviours
maintained by negative reinforcement. This apparent paradox can be explained by the
fact that the Time-out procedure does not allow the subject to escape the situation
completely, but only delays it.
