Composite Scores or Indexes The most reliable scores for the DTVP-A
are the indexes. These scores are found by adding the standard scores of the
subtests that comprise a composite and converting the sum to an index.
General Visual-Perceptual Index: The GVPI is the best
measure of what the majority of people mean when they say "visual perception."
Data from six subtests, each of which measures a different type of visual
perception in a different manner, contribute to the GVPI. When GVPIs are below
90, examiners need to pay more attention to the clinically important indexes-
the Motor-Reduced Visual Perceptual Index (MRPI) and the Visual-Motor
Integration Index (VMII). Examination of these indexes may help explain the
causes for low GVPIs.
Motor-Reduced Visual Perception
Index: Of all of the DTVP-A indexes, the MRPI is the "purest" and most
direct measure of visual perception in that only minimal motor skills (e.g.,
pointing) are required to show perceptual competence. This index is formed by
combining the standard scores from the Figure-Ground, Visual Closure, and Form
Constancy Subtests.
Visual-Motor Integration Index: To
do well on this composite, individuals must perform complex eye-hand
coordination tasks. Low scores do not necessarily indicate poor visual
perception; they may mean that the individuals have awkward hand movements or
that they have difficulty coordinating hand-to-eye movements. This index is
formed by combining the standard scores of the Copying, Visual-Motor Search, and
Visual-Motor Speed Subtests.
Special Features of the
DTVP-A:
- Subtests were developed to be appropriate for
adolescents and adults.
- The normative sample reflects the current
population characteristics of the United States relative to race, ethnicity,
gender, geographic region, parent education, and income.
- Internal
consistency, stability, and interscorer reliability for all indexes are high.
-
Validity evidence shows that all DTVP-A subtests and indexes are useful for
measuring visual-perceptual and visual-motor integration skills.
-
Evidence is provided to show that the test is unbiased with respect to gender
and race.

Developmental Test of Visual Perception (DTVP-2)
OUR
PRICE-$300.00
Ages: 4-0 through 10-0
Testing Time: 30 minutes to 1 hour
Administration: Individual
The DTVP2 is the 1993 revision
of Marianne Frostig’s popular Developmental Test of Visual Perception
(DTVP). The original version of the test was administered to more than 6 million
children. The new edition includes numerous improvements, is suitable for
children ages 4 to 10, measures both visual perception and visualmotor
integration skills, has eight subtests, is based on updated theories of visual
perceptual development, and can be administered to individuals in 35 minutes.
Of all the tests of visual
perception and visualmotor integration, the DTVP2 is UNIQUE in that
its scores are reliable at the .8 or .9 levels for all age groups; its scores
are validated by many studies; its norms are based on a large representative
sample keyed to the 1990 census data; it yields scores for both pure visual
perception (no motor response) and visualmotor integration ability; and it
has been proven to be unbiased relative to race, gender, and handedness. The
DTVP2 subtests are Eye-Hand Coordination, Copying, Spatial Relations,
Position in Space, Figure-Ground, Visual Closure, Visual-Motor Speed, and Form
Constancy.
The DTVP2 was
standardized on 1,972 children from 12 states. Characteristics of the normative
sample approximate those provided in the 1990 Statistical Abstract of the
United States with regard to gender, geographical region, ethnicity, race,
and urban/rural residence. Standard scores, NCEs, percentiles, and age
equivalents are provided in the Examiner¹s Manual. Internal consistency
reliabilities (i.e., alphas) and stability reliabilities (i.e., testretest)
for all scores exceed .8 at all ages. Criterion-related validity is evidenced by
correlating DTVP2 scores with those from the Developmental Test of
Visual-Motor Integration (VMI) and Motor-Free Visual Perception
Test. Construct validity is supported by correlations with mental ability
tests, achievement tests, and age. Studies also show that the subtests are
intercorrelated and that groups known to have visual perceptual difficulties do
poorly on the DTVP2. Results of factor structure and gender/race/handedness
bias studies also reinforce the validity of the
DTVP2.

Motor-Free Visual Perception Test (MVPT-3)
OUR PRICE-$180.00
Ages: 4 through 85
years
Testing Time: 20 minutes
Administration: Individual
The
third edition of the Motor-Free Visual Perception Test (MVPT-3) is appropriate
for children and adults ages 4 through 85 years. Designed to assess visual
perception without reliance on an individual's motor skills, the MVPT-3 is
particularly useful with those who may have learning, cognitive, motor, or
physical disabilities. The MVPT-3 can be used for screening as well as
diagnostic and research purposes by teachers, psychologists, educational
specialists, rehabilitation therapists, and others who need a quick, highly
reliable, and valid measure of overall visual-perceptual processing ability in
children and adults.
The MVPT-3 measures skills without copying tasks.
It contains many new, more difficult items at the upper end for older children
and adults. Tasks include matching, figure-ground, closure, visual memory, and
form discrimination. Stimuli are line drawings. Answers are presented in
multiple-choice format. Responses may be given verbally or by pointing. Standard
scores and percentiles are provided. Item response times may be interpreted in
terms of functional behavioral categories. Clinical population comparisons are
also provided. The test takes about 20 minutes and is individually administered.

Test of Auditory
Processing Skills - Third Edition (TAPS-3)
Nancy
A. Martin and Rick Brownell
OUR PRICE-$160.00
Ages: 4-0 to 18-11 years
Administration Time:
Approximately 60 minutes
Administration:
Individual
The TAPS-3
represents a very thorough reshaping of the Test of Auditory Perceptual Skills
(TAPS-R) and the Test of Auditory-Perceptual Skills: Upper Level (TAPS-UL), both
previously authored by Morrison Gardner. The most obvious change is that there
are no longer two "levels" of the test; the TAPS-3 offers seamless coverage.
The TAPS-3 measures
what a person does with what is heard, and is intended to be used along with
other tests as part of a battery. It is designed for use by speech-language
pathologists, audiologists, school psychologists, and other testing
professionals.
Other differences
are apparent in the details of the test structure. The order of subtests has
been amended to reflect a developmental progression of tasks from easiest to
most difficult. Four new subtests have been added:Phonological Segmentation;
Phonological Blending; Auditory Comprehension; Auditory Reasoning (this replaces
Auditory Processing subtest from previous Editions).
New items were
developed for many subtests, while some existing test items were retained. The
content of some subtests has been completely revised; for example, the last
subtest, Auditory Reasoning, contains all new items specifically designed to tap
auditory cohesion, a higher-order process. An optional Auditory Figure-Ground
task has also been added as a supplemental subtest presented in CD format to
flag attention problems and give feedback about how the child's auditory
processing system works in "real-world" situations.
The subtests are:
Word Discrimination;Phonological Segmentation;Phonological Blending; Numbers
Forward; Numbers Reversed; Word Memory; Sentence Memory; Auditory Comprehension;
Auditory
Reasoning.
There are also
notable differences in how scores are derived and the types of scores obtained.
The use of partial credit in some subtests reflects more accurately the child's
auditory abilities. In addition to one overall score, individual subtest scores
are combined to derive three cluster scores: Basic Auditory Skills (Word
Discrimination, Phonological Segmentation, and Phonological Blending subtests),
Auditory Memory (Number Memory Forward, Number Memory Reversed, Word Memory, and
Sentence Memory), and Auditory Cohesion (Auditory Comprehension and Auditory
Reasoning subtests). The introductory chapter of the manual presents an updated
literature review

Test of Auditory Reasoning and
Processing Skills [TARPS]
Morrison F. Gardner
OUR PRICE-$90.00
Ages: 5 Through 14
Testing Time: 10 – 15 Minutes
The TARPS
measures the quality and quantity of a subject’s auditory thinking and reasoning
- the ability of a child to draw conclusions, to make inferences, and to apply
and use judgment from what the child auditorily perceives. While many of the
questions and statements do reflect what a child has learned from home and
formal education, the purpose of this test is to determine what the child does
with what he or she has learned. For example, factual information learned from
home and formal education usually suggest a measure of memory but does not
always measure how a child uses what he or she has learned.
This test
will measure a child’s ability to think logically, conceptually, and abstractly.
It is the ability of a child to perceive auditory matter accurately, make sense
of it, and to use judgment and common sense in bringing the matter to a
conclusion.
Another purpose of the TARPS is to assess how well a child
can pick out key words in a question or a statement and know that that key word
holds the clue to the answer or is the answer.

Test of Visual-Perceptual
Skills - Third
Edition [TVPS-3]
Nancy Martin
OUR PRICE-$200.00
Ages 4-0 through 18-11
Individual
Administration
Norm-Referenced on over 2000 students
Now, just one test covers all of the ages that were
previously covered by the two forms of the earlier test (TVPS-R and
TVPS-UL-R).
The TVPS-3 remains an easy to use assessment to determine the
visual perceptual strengths and weaknesses of students aged 4-0 through 18-11.
Visual perception is an important ability that enables one to make sense out of
what is seen (in contrast to visual acuity tests which determine just that
something was seen by the individual).
The TVPS-3 utilizes black and white line drawings as stimuli for
all of the perceptual tasks; the stimulus plates are bound in a convenient
easel-style booklet. The items are still presented in a multiple-choice format,
and responses can be made vocally (by saying the letter of the response choice)
or by pointing to the answer choice. This format is ideal for use with students
who may have impairments in motor, speech, hearing, neurological, or cognitive
functions.
There are still 16 plates in each of the perceptual areas so
that the length of the test remains the same as previous editions:
* Visual Discrimination
* Visual Memory
* Visual Spacial
Relationships
* Form Constancy
* Visual Sequential Memory
*
Figure-Ground
* Visual Closure
Ceilings ensure that the more difficult items do not unduly tax
younger students, yet enable the examiner to obtain a reliable and accurate
measurement of the students' abilities at all ages.
By analyzing the subtest score patterns, the examiner make
functional comparisons of the child's abilities and provide a basis for planning
the appropriate remediation. The manual contains an updated review of literature
pertaining to the importance of visual perceptual ability to the tasks a child
faces in both school and home settings.
The TVPS-3 also provides new, nationally stratified norms on
over 2000 students.
Administration and Scoring
The TVPS-3 is administered to
individuals; it is untimed and takes about 25 minutes to complete. The TVPS-3
may be used by a number of different types of professionals: occupational
therapists, learning specialists, optometrists, and rehabilitation specialists.
Scoring is quick and uncomplicated. Raw scores are reported as scaled scores and
percentile ranks for each subtest, the overall total score is reported as a
standard score and percentile rank. Age-equivalents are also provided for the
subtest and overall scores.

Test of Visual-Perceptual Skills
(non-motor):Upper Level [TVPS(NM):UL]
Morrison F. Gardner
Ages: 12 Through 18
Years
The Upper Level of the Test of Visual-Perceptual Skills
(non-motor) was developed to provide a measurement of a subject’s
visual-perceptual strengths and weaknesses with greater detail and precision
than had previously been available. Like the original TVPS, the Upper Level also
measures the following seven visual-perceptual skills: Visual Discrimination,
Visual Memory, Visual Spatial Relationships, Visual Form Constancy, Visual
Sequential Memory, Visual Figure-Ground, and Visual Closure.
