Purposes
PKP
•Overview Procedural Knowledge Profile
(PKP)
•Rationale for its development
•Provide intervention suggestions based on
Procedural Knowledge Profile
1. Evaluates ability to interact effectively
within an environment and
2. Demonstrates knowledge of the function
of the objects contained within the
environment
Linguistic
Procedural
Knowledge
• Difficulty with “
simple
language concepts (e.g.,
verbs, prepositions,
pronouns)
• Difficulty with language
acquisition despite
exposure and instruction
• Strong operational
competence
• Imitation skills often poor
in contrast to strong
observational skills
• Skills often learned
without instruction
• More complex learning
may require some
additional language input
PKP
Does the content of the
PKP help explain disparity
between measured ability
and perceived capacity?
These distinctions may help explain why persons with ASD
may appear more competent than standardized tests often reveal

Clinically relevant aspects
•Procedural knowledge evolves through
non-verbal relationship with objects
•Procedural knowledge is obtained
through observation of predictable and
repeated goal oriented routines
Clinically relevant aspects
•Spoken language is not required but
sometimes assists in the comprehension of
the function of objects in a natural setting
•Procedural understanding is the foundation
for mapping language (symbols) to concepts
already within the individual’
s repertoire
•Helps identify three clinical sub-groups
Contemporary Treatments
and Relationship to PKP
Comprehension
Comprehension is …“
the essence of language”
(Savage-Rumbaugh & Lewin, 1994)
•Children with ASD have weakness in declarative
knowledge (concept formation)
•Children with ASD have strength in procedural
knowledge (knowledge for doing things)
(Goldstein, Minshew, & Siegel 1994)
•Comprehension….as the power that fuels
expression (Twachtman - Cullen, 1997)
Theory of Human Cultural Learning
(Vygotsky; Tomasello, Kruger and
Ratner)
Language development is dependent on:
•A cultural context that structures events for
a child
•Child’
s capacity to learn from this cultural
structuring
Developmental Pragmatics
• DP movement developed in the late
1970’
s and early 1980s. Promoted the
view that:
Social context of naturally occurring routines
was considered of primary importance in
language development
2
Developmental Pragmatics
Child was viewed as an active participant in
learning and a social participant rather than
under the agenda and control of a teacher with
a specific reinforcement schedule and variety
of instructional variables
“
[J]oint attention, early language skills, and
imitation are core deficits that are the
hallmarks of the disorder, and are
predictive of longer-term outcome in
language, adaptive behaviors, and
academic skills.

Natural Language Paradigm
Applied Behavioral Analysis
Natural child-centered routines that recur in
everyday life with family and peers as a
primary intervention context (Koegel &
Johnson, 1989: Scheibner & Pierce, 1983)
Rationale for highly repetitive non-contextual
approach:
•Children with ASD could not learn in natural
environments because of extreme learning and
attentional problems
•Natural environments do not provide practice
opportunities and systematic reinforcement
(Lovaas 1981)
“There is now a large body of empirical support for more
contemporary behavioral approaches using naturalistic
teaching methods that demonstrate efficacy for teaching not
only speech and language, but also communication. ….include
natural language paradigms (Koegel et al., 1987), incidental teaching (Hart, 1985;
McGee et al., 1985; McGee et al., 1999), time delay and milieu intervention (Charlop
et al., 1985; Charlop and Trasowech, 1991; Hwang and Hughes, 2000; Kaiser, 1993;
Kaiser et al., 1992), and pivotal response training (Koegel, 1995; Koegel et al., 1998).
These approaches use systematic teaching trials that have several common active
ingredients: they are initiated by the child and focus on the child’
s interest; they are
interspersed and embedded in the natural environment; and they use natural
reinforcers that follow what the child is trying to communicate. Only a few studies,
all using single-subject designs, have compared traditional discrete trial with
naturalistic behavioral approaches. These studies have reported that naturalistic
approaches are more effective at leading to generalization of language gains to
natural contexts (Koegel et al., 1998; Koegel et al., 1992; McGee et al., 1985).”

Floor time
Especially relevant is the suggestion to
follow the child’
s lead –typically occurs
in natural environment
Evidence from
Observational Learning
Influences to what has become
PKP
•Lack / Limited spoken language
comprehension
•Our growing interest in Observation Learning
•Clinical encounters reveal relative strength especially in relationship to language profile
•Too limiting to restrict instruction to discrete
trial, table top, scripted instruction, etc
•Wanted to maximize strength of acquiring
information and skills into a clinically practical
approach

Abstract
Symbolic
“Don’
t do what I do, do what I say.”
Evidence from ESM Interest
Typical Findings
Bandura & Walters, 1963
•88% of children imitated the
model’
s aggressive behaviors.
•40% of same children repeated
these behaviors 8 months later.
Key Point
Children imitated novel behaviors
• With high frequency & precision
• Without any reinforcements,
prompts or instructions

Survey
Electronic Screen Media for Persons
with Autism Spectrum Disorders –Shane & Albert
(ASHA –2005 & submitted for Publication)
•Quantification of television and computer use
•Instructional potential of medium
–Extent of interaction
–Nature of interaction
•Distributed Survey Design
– N = 89
–Drawn from families having children
(preschool to 12 years) on the autism spectrum
MAIN FINDINGS
MAIN FINDINGS
•More time with media than other activities.
•Considerable “operational
competence”, but not equal to typical
children.
•Prefer animated characters, but need to explore
actual preference by individual.
•Deferred vocal imitation occurs frequently.
•Families change viewing habits to
accommodate child on autism spectrum.
Fundamental Question
•Prefer characters in media over commercial
products.
•Motor imitation and copying reported.
Can the recognized high level of interest in OL
and ESM, be harnessed and used as an
essential and effective method of instruction?
We submit PKP can be used to as a way to
improve instruction. It takes advantage of
naturally occurring opportunities as well as
knowledge / skills the child has acquired by
observation with or without adult directed
training.
PKP
•Functional
•Naturalistic
•Map language onto "existing" capacity

•Matching (identity match)
•Student matches identical representations
of noun items that are the recipient of
procedural functions, found within a
specific environment. (Refer to Vocabulary
lists).
• Student matches noun items (as above) to multiple
examples of nouns that are not identical but are at the
same level of representation

Associated Behaviors
Level 2 Student Profile
PKP Analysis
• Primarily ‘
Adult Directed”procedural skill acquisition
• Level of prompts are at the symbolic level, e.g.,
conventional gestures, visuals, spoken language,
written language
• Concepts that are understood through procedural
performance--either task specific or across settings--are
identified
• Concepts that need to be explicitly taught are identified
• Level of ability to perform a goal-oriented sequence of
procedural functions is evaluated
Individual may have difficulty in following areas:
•Attending to task
•Initiating
•Maintaining representation of the end goal of the
task (working memory)
•Planning steps needed to complete a sequence
•Processing temporal information (concepts of
beginning, middle, end)
•Understanding symbolic representation
•Connecting relational aspects of language

Video Based
• Student reviews video of a procedural sequence
• Screen shots (scene cues) are taken as a visual support
to trigger retrieval of each step in the procedural
sequence
In Vivo
• Student uses the scene cues that are placed in a leftright array to perform the procedural sequence
• Prompts are either conventional gestures, visual or
spoken assists

Video based
• Student reviews video of a procedural sequence
In Vivo
• Screen shots (scene cues) are taken as a visual support to
trigger retrieval of each step in the procedural sequence
• Student independently refers to the scene cues as a memory
aid to recall the next behavioral chunk that needs to be
recalled and performed
• Student begins to successfully initiate sequences after long
delays by taking advantage of scene cues to help remember
the correct number and order of procedural steps
Table Top Activities-Vocabulary
Development
•Student interprets action symbols linking actor
and recipient of the action after repeated
rehearsal of the procedural function with the
visual support of a scene cue
•Student acts out the scene using element cues
•Student interprets locative prepositions that are
embedded with action verbs after repeated
rehearsal of the procedural function with the
visual support of a scene cue
•Student acts out new procedural routines using
elements arranged in novel sequences
Benefits of PKP
•Identifies student sub-groups
