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)
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)
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
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

Test of Auditory Reasoning and Processing Skills [TARPS]
Morrison F. Gardner
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
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.
| TVPS(NM):UL is no longer available - we will continue to sell the record forms only. Please see the updated TVPS-3 (B004-3 listed above) |
