Descriptions
Central
Processing Skills can be viewed as multiple intelligences.
They are based on the Cattell-Horn-Carroll (C-H-C) Theory of
Cognitive Abilities (1993). Unlike other theories of
multiple intelligence (e.g., Gardner, 1983) standardized
tests which validate the constructs of the C-H-C model
exist. Perhaps the most comprehensive of such tests is the
Woodcock-Johnson Psychoeducational Battery – Third Edition (WJ-III).
The
existence of Central Processing skills and their importance
in the development of academic skills in children and
adults, has been well documented in factor-analytic
research. Certain Central Processing skills underlie certain
types of academic achievement, depending upon the age of the
individual and the area of achievement being considered.
For
example, in the six year-old child, learning to read is
extremely dependent upon Auditory Processing skills. As the
child’s age increases, certain reading skills (in
particular, reading comprehension) will also be dependent on
other Central Processing skills, such as
Comprehension-Knowledge. In other words, Central Processing
skills are differentially associated with academic
development.
The
following descriptions of the Central Processing skills have
been adapted from Hessler (1997) and Woodcock, McGrew, and
Mather (2001).
Auditory Processing
Auditory Processing is the
ability to analyze and synthesize auditory information.
Auditory Processing includes Phonemic Awareness, which is
the ability to differentiate phonemes (individual units of
sound in language, such as "t" in the word "cat"). Phonemic
Awareness is extremely important in the development of basic
reading skills. Children who have difficulties with Phonemic
Awareness will have problems with learning the sounds of
individual letters, word analysis and word attack.
Comprehension suffers because the child expends much of
his/her cognitive resources decoding each individual word.
Children with phonemic
awareness difficulties make up the majority of individuals
with reading and writing disorders. Whole language
approaches should not be used for children with problems in
this area. Phonics-based approaches such as Orton-Gillingham
should be used. Sounding-out words is a good start, because
the child must learn to employ auditory as well as visual
cues in sound-symbol integration.
It is possible to determine if a child
has difficulties with phonemic awareness skills simply by
examining the nature of his/her spelling errors. If a child
spells words phonetically (e.g., "Kof" for "cough"; "rane"
instead of "rain"), then it is probable that he or she has
grasped the concept of phonics and probably has difficulties
with Orthographics (see below). If the child’s errors show
no pattern of phonetic spelling, then it is probable that
the child’s phonetic skills are not adequately developed and
that a phonics-based program is needed.
Fine Motor Skills
Fine Skills
involves the ability to control purposeful fine motor
movements. This is a lower order cognitive skill.
Younger
children with Fine Motor problems may have difficulties
using simple tools such as scissors. Older children with
Fine Motor difficulties will have problems performing the
mechanical aspects of handwriting speed and legibility.
Fluid Reasoning (Flexible Problem-Solving)
Fluid
Reasoning involves the ability to reason, form concepts, and
solve problems using unfamiliar information or novel
procedures. It is a basic reasoning process involving the
manipulation of abstractions, rules, and logical relations.
This is a higher order cognitive skill.
Children with problems in this area will
experience difficulties with novel, unfamiliar reasoning and
problem solving, including difficulties processing new or
abstract information, concepts that require organization or
integration, information that requires the invention of new
cognitive strategies, and tasks that require one to
adaptively react to unfamiliar situations.
Long-Term Retrieval (Associative Memory)
Long-Term
Retrieval involves the ability to store information and
fluently retrieve it later through association. This is not
to be confused with acquired stores of knowledge such as
Comprehension-Knowledge. Comprehension-Knowledge is the
actual "store" of information in Long-Term Memory. Long-Term
Retrieval is the process by which this information is stored
and retrieved.
Children with
difficulties in this area will experience problems with the
fluent storage and retrieval of information from long-term
memory; the retrieval of information will be slow, laborious
and inconsistent, requiring extra effort on the individual's
part. This may make it difficult for the child to gain
access to his/her prior knowledge when he/she needs it, or
will require so much effort that little cognitive energy is
left for solving problems that are presented to him/her.
Orthographic Processing
Orthographic
Processing involves the ability to recognize words by their
letter patterns and to apply the alphabetic principle to
print.
Orthographic
Processing skills develop only through frequent exposure to
printed words. Difficulties in this area often results in
poor and non-automatic sight word recognition and spelling,
even though the child’s phonics analysis strategies might be
well developed. If a child’s shows a pattern of
phonetically-based spelling errors (e.g., "table" for
"table"; "hows" for "house"; "koff" for "cough"), then it is
likely that the child’s spelling difficulties are not
phonetically-based but rather, that he/she needs to work on
the development of Orthographic Processing skills.
Processing Speed
Processing Speed is the
ability to rapidly and automatically process information and
perform cognitive tasks, particularly when measured under
pressure to maintain focused attention. Processing speed,
also referred to as "automaticity", is strongly associated
with academic fluency.
Children with Processing
Speed difficulties will have problems processing information
and performing tasks as fluently and automatically as
his/her age-mates, and as he/she thinks. This includes
deficient mental speed, and indicates that he/she will
search and scan for information in a slow and non-automatic
manner.
Individuals who lack
automaticity must essentially "think through" most
activities, rather than perform them in a fluent, easy, and
unconscious manner. While they may be able to allocate the
resources to perform some tasks fairly fluently and well,
they may essentially often run out of cognitive energy to do
so; this may particularly occur toward the end of the school
day when one's mental resources are exhausted. Variable
performance may therefore be evident throughout the school
day.
Short-Term Memory
Short-Term Memory involves
the ability to apprehend ant hold information in immediate
awareness and then use it within a few seconds.
Children with Short-Term Memory problems
will experience difficulties retaining information in
immediate awareness long enough to process it conceptually.
The individual will therefore either miss or lose
information, or he/she will need to use limited conceptual
processes to compensate for the short-term memory
difficulties. Conditions such as Anxiety, Depression, and
ADD/ADHD can exacerbate and/or cause Short-Term Memory
failure.
Comprehension-Knowledge
Comprehension-knowledge is the breadth
and depth of knowledge of a culture, the ability to
communicate one’s knowledge (especially verbally), and the
ability to reason using previously learned knowledge or
procedures.
Children with problems in this area will
experience difficulties comprehending verbal information and
using this information for reasoning and problem solving.
Visual Processing (Visual-Spatial
Thinking)
Visual Processing is the
ability to analyze and synthesize visual information to
store and recall visual representations.
Children with problems in
this area will experience difficulties performing tasks that
require visual recognition, visualization, spatial
abilities, and visual imagery - the type of processing that
is required during social perception (e.g., perceiving
facial cues and body language), and during such activities
as art, geometry, landscaping, etc.
Working Memory
Working memory, a variant of Short-Term
Memory, involves the ability to temporarily store and
perform a cognitive operation on information, and to divide
attention and the management of short-term memory.
Children with Working
Memory problems will experience difficulties remembering or
processing information when extraneous stimuli are present,
or when he or she uses it to solve problems or integrate
information.

Educational
Recommendations
The
following educational recommendations, originally developed
by Hessler (1997), are based on research which indicates
that Central Processing (Lower and Higher-Order Cognitive)
Skills underlie and are differentially associated with
academic achievement. These Central Processing Skills are:
Auditory
Processing
Fine Motor Skills
Fluid Reasoning (Flexible Problem-Solving)
Long-Term Retrieval (Associative Memory)
Orthographic Processing
Processing Speed
Short-Term Memory
Verbal
Comprehension-Knowledge
Visual Processing (Visual-Spatial Thinking)
Working Memory
In
psychoeducational evaluations, Dr. Rickman obtains
individual performances across many of these areas of
central processing. By doing this, students’ weaknesses in
any area(s) of central processing can be addressed with
specific, research-based educational recommendations. These
recommendations are as follows:
EDUCATIONAL RECOMMENDATIONS FOR INDIVIDUALS
WITH AUDITORY PROCESSING
(PHONOLOGICAL AWARENESS) DIFFICULTIES (Hessler, 1997):
1. Consider that the
individual will experience difficulties learning phonics
based reading and spelling skills.
2. Emphasis should be
placed on teaching phonological awareness and decoding
skills in association with meaningful reading.
3. If not already
performed, a comprehensive hearing examination should be
conducted.
EDUCATIONAL RECOMMENDATIONS FOR INDIVIDUALS
WITH FINE MOTOR DIFFICULTIES (Hessler,
1997):
1. Consider that the
individual will experience difficulties performing the
mechanical aspects of handwriting speed and legibility.
2. Provide additional time
for the individual to perform tasks that require writing.
3. Lower the standards (at
least temporarily) for acceptable handwriting quality.
4. Provide structured
handwriting activities - such activities should provide a
variety of concrete beginning fine motor activities that
lead directly into beginning handwriting activities (e.g.,
dot-to-dot, tracing, and letter and word copying
activities). During these activities, the teacher should
define the motor plans for letters and words, encourage the
individual to verbally rehearse these plans, and then
practice executing the motor plan.
5. Be patient with the
individual while he/she is developing better handwriting
performance.
6. Carefully structure and
design written assignments to ensure success.
7. When it is important
that the individual demonstrate his/her knowledge in a
particular area, permit him/her to respond orally or in
performance based ways, rather than just in writing - if
writing is required, shorten the written requirements (e.g.,
use short answer rather than essay formats)
8. When extensive
note-taking is required, permit the individual to use a tape
recorder and/or have access to copies of peers' notes or
notes developed by the teacher.
9. Permit the individual
to use computer-based word processing and word prediction
programs.
EDUCATIONAL RECOMMENDATIONS FOR INDIVIDUALS
WITH FLUID REASONING
DIFFICULTIES (Hessler, 1997):
1. Consider that the
individual will experience difficulties with novel,
unfamiliar reasoning and problem solving, including
difficulties processing new or abstract information,
concepts that require organization or integration,
information that requires the invention of new cognitive
strategies, and tasks that require one to adaptively react
to unfamiliar situations.
2. Provide activities that
encourage the individual to activate his/her prior
knowledge, that engage him/her in prediction, and that
encourage him/her to monitor meaning during learning tasks.
3. Provide hands-on,
activity-oriented tasks and activities that include
interactive activities that encourage the individual to be
actively involved in the learning process.
4. During academic
instruction, much emphasis should be placed on pre-reading,
pre-writing, and pre-mathematics activities - this is
important to assess the individual's prior knowledge and to
help the individual activate his/her prior knowledge and
organize his/her conceptual schema.
5. Emphasis should be
placed on teaching procedures and concepts in a concrete,
over-learned manner - use manipulables, figures, diagrams,
graphs, etc.
6. Much time needs to be
provided for the active construction of the relationships
among the taught procedures and concepts. This extended
activity time needs to provide multiple examples, which
include concrete representations and offers feedback from
the physical world, from adults, and from tasks related to
social interaction with peers.
7. The individual's
teachers need to structure for, and to highlight, the links
between related concepts and procedures; teaching and
practice time making connections between old understandings
may be more critical to learning than the introduction of
new knowledge.
8. To facilitate
comprehension, use such activities as previewing and
advanced organizer activities, concept analysis activities,
reciprocal teaching activities, POSSE (Predict, Organize,
Search, Summarize, Evaluate) activities, and concept mapping
activities.
9. Use of elements of
effective teaching and direct instruction to reduce the
abstract nature of lessons, therefore allowing the
individual to better comprehend the material.
A. Advanced Organizers
(e.g., statement of instructional objective; review of
previous, relevant concepts/skills).
B. Instruction in
Domain-Specific Skills (e.g., examples, non-examples,
modeling, definitions)
C. Guided Practice
(e.g., hands-on activities, checking for understanding,
monitoring student learning)
D. Independent Practice
(e.g., small group activities, homework, seatwork,
learning center activities)
E. Closure/Summary
(e.g., review of the concepts that were studied, review of
why these concepts are important)
EDUCATIONAL RECOMMENDATIONS FOR INDIVIDUALS
WITH LONG-TERM RETRIEVAL
DIFFICULTIES (Hessler, 1997):
1. Consider that the
individual will experience difficulties with the fluent
storage and retrieval of information from long-term memory;
the retrieval of information will be slow, laborious and
inconsistent, requiring extra effort on the individual's
part. This may make it difficult for one to gain access to
his/her prior knowledge when he/she needs it, or will
require so much effort that little cognitive energy is left
for solving problems that are presented to him/her.
2. Provide additional time
for the individual to answer questions and to perform tasks.
3. Provide prompting,
cueing, and reinforcement to help the individual retrieve
information when he/she needs it.
4. Teach information that
is important in an intensive way, so that it is
"over-learned", and retrieval is facilitated.
5. Use tests that employ a
multiple-choice, true-false, or answer-matching format so
that the individual can better demonstrate his/her knowledge
(e.g., rather than tests that require the recall of specific
information).
6. Teach visual
association or mental imagery strategies to enhance the
retrieval of information.
EDUCATIONAL RECOMMENDATIONS FOR INDIVIDUALS
WITH ORTHOGRAPHIC PROCESSING
DIFFICULTIES (Hessler, 1997):
1. Consider that the
individual will experience difficulties learning to
recognize words by their letter patterns - this often
results in poor and non-automatic sight word recognition and
spelling, even though phonics analysis strategies might be
well developed.
2. The individual should
be encouraged to use compensatory strategies during writing;
for example, he/she would profit from having access to a
traditional or electronic spelling dictionary, an electronic
notebook, or a prepared spelling list of frequently used
words so that he/she may more easily access the correct
spelling of words when necessary.
3. To help the individual
learn to recognize sight words and to spell words,
instructional strategies should include teacher-directed,
systematic practice with controlled amounts of new
information, modelling and immediate feedback, multisensory
instruction, and organized and sequential instruction with
basic skills. He/she may also benefit from learning to spell
words that he/she frequently uses when writing, and from
learning to spell the most frequently used words (e.g.,
"Spelling for Writing List").
EDUCATIONAL RECOMMENDATIONS FOR INDIVIDUALS
WITH PROCESSING SPEED (AUTOMATICITY)
DIFFICULTIES (Hessler, 1997):
1. Consider that the
individual will experience difficulties processing
information and performing tasks as fluently and
automatically as his/her age-mates, and as he/she thinks.
This includes deficient mental speed, and indicates that
he/she will search and scan for information in a slow and
non-automatic manner.
2. Particular
consideration should also be given to the implications of
the lack of automaticity during the day. Individuals who
lack automaticity must essentially "think through" most
activities, rather than perform them in a fluent, easy, and
unconscious manner. While they may be able to allocate the
resources to perform some tasks fairly fluently and well,
they may essentially often run out of cognitive energy to do
so; this may particularly occur toward the end of the school
day when one's mental resources are exhausted. Variable
performance may therefore be evident throughout the school
day.
3. Provide additional time to
complete tasks.
4. When the individual is
required to perform long, involved tasks that require
extensive problem solving and reasoning, he/she should
receive ongoing support and reinforcement.
5. When it is essential
that the individual learn basic skills and facts at an
automatic level, extra practice time will be necessary.
Those working with the individual will therefore need to
display patience and empathy, as well as additional
structured support and practice.
EDUCATIONAL RECOMMENDATIONS FOR INDIVIDUALS
WITH SHORT-TERM MEMORY
DIFFICULTIES (Hessler, 1997):
1. Consider that the
individual will experience difficulties retaining
information in immediate awareness long enough to process it
conceptually. The individual will therefore either miss or
lose information, or he/she will need to use limited
conceptual processes to compensate for the short-term memory
difficulties.
2. Provide information and
instructions in short sequences and in a relatively slow
manner, making certain that the individual understands.
3. Record long sequences
of information so that the individual can refer to it as
necessary (rather than being required to remember it).
EDUCATIONAL RECOMMENDATIONS FOR INDIVIDUALS
WITH VERBAL COMPREHENSION-KNOWLEDGE
DIFFICULTIES (Hessler, 1997).
1. Consider that the
individual will experience difficulties comprehending verbal
information and using this information for reasoning and
problem solving.
2. Make verbal directions
and explanations concrete and concise, making certain that
the individual understands.
3. Always assess the
individual's prior knowledge to determine whether or not
he/she has the knowledge and knowledge structures to perform
the presented tasks. If not, the necessary information and
knowledge will need to be learned by him/her, before task
performance can be expected.
4. Teach the necessary
vocabulary and verbal reasoning in association with reading,
written expression, and mathematics instruction.
EDUCATIONAL RECOMMENDATIONS FOR INDIVIDUALS
WITH VISUAL PROCESSING
DIFFICULTIES (Hessler, 1997).
1. Consider that
the individual will experience difficulties performing
tasks that require visual recognition, visualization,
spatial abilities, and visual imagery - the type of
processing that is required during social perception
(e.g., perceiving facial cues and body language), and
during such activities as art, etc.
