PRT is an intervention or treatment approach derived from the principles of applied behavior analysis (ABA;
R. L. Koegel, Openden, Fredeen, & Koegel, 2006). PRT focuses on building a
set of four "pivotal" skills or behaviors, including (a) motivation
to respond to natural environmental and social cues, (b) responding to multiple
(rather than single) cues in the environment, (c) management of own behavior,
and (d) self-initiation of behavior in appropriate contexts.
These are called pivotal behaviors because
they are likely to have a positive effect on the learner's acquisition and
use of a wider range of developmental or behavior skills than those specifically
targeted for the PRT intervention (Coolican, Smith & Bryson, 2010; Smith,
Koegel, Koegel, Openden, Fossum, & Bryson, 2010).
The
10 core goals of PRT are to:
·
Teach learners to respond to the many
learning opportunities and social interactions that occur in the natural
environment
·
Decrease learners' needs for constant
supervision and support from adults
·
Promote family involvement and improve the
quality of life for all family members
·
Decrease the number of services delivered
in separate settings that remove learners from the natural environment
·
Improve learners' academic performance
·
Advance learners' communication and
language skills
·
Foster learners' social interactions and
friendships with typically developing peers
·
Reduce learners' interfering behaviors
(e.g., disruptive, repetitive, stereotypical)
·
Move learners toward a typical
developmental trajectory by teaching a diverse number of behaviors
·
Broaden learners' interests
This approach gives the learner opportunities to make choices and share control
of the interactions with adults. The teaching that follows these interactions
enhances learners' motivation to engage with objects and activities that
maximize the reward strength (i.e., the intrinsic motivating power of the
activity or object) and minimize the need for extrinsic reinforcers (e.g.,
stickers, tokens, edibles).
Why developed?
PRT was developed by Robert Koegel and Laura
Schreibman, who arranged teaching settings in which children were allowed to
choose materials and activities while adults interspersed teaching
opportunities within learning and play activities. Children in these settings
learned new skills and maintained those skills over time (Schreibman, 2006).
PRT, like all other behavioral teaching approaches (and probably non-behavioral
teaching approaches as well), uses the fundamental teaching tools of
reinforcement, antecedent
control, prompting,
fading,
shaping, and chaining
The first behavioral interventions for children and youth with ASD
successfully used the basic behavioral principles of reinforcement, punishment, and shaping to teach target behaviors
such as speech, imitation, following instructions, and reduction of unwanted
behaviors (Ferster, 1961; Ferster & DeMyer, 1962).
PRT, like all other behavioral teaching approaches (and probably
non-behavioral teaching approaches as well), uses the fundamental teaching
tools of reinforcement, antecedent
control, prompting,
fading,
shaping, and chaining.
PRT uses both motivational and learning principles and applies them
systematically in natural settings to optimize the development of fundamental
skills that are pivotal to the development of a wide range of other skills.
PRT is a technique that a wide range of individuals can use, including
family members and school staff, as well as individual therapists and
consultants (e.g., speech-language pathologists, occupational therapists).
One
primary goal of PRT is to promote generalization and maintenance
of mastered skills. A successful strategy for addressing this goal is to focus
on skill deficits in the natural environment, in as many naturally occurring
opportunities as possible, and with multiple intervention partners (National
Research Council, 2001). For example, it is much more likely that learners will
maintain newly acquired skills, such as buttoning, and generalize to different
types of buttons if they button pajamas at night, coats when going outside, or
a doll's dress during play-all naturally occurring opportunities that take place
throughout the daily routine.
PRT can be implemented in
any setting and context where (a) the learner has consistent contact with an
individual and (b) there are activities or objects that the learner prefers
