What are the
WISC-V – 10 Subtests producing the Five Primary Index Scales
- Similarities (VCI)
- Vocabulary (VCI)
- Block Design (VSI)
- Visual Puzzles (VSI)
- Matrix Reasoning (FR)
- Figure Weights (FR)
- Digit Span (WMI)
- Picture Span (WMI)
- Coding (PSI)
- Symbol Search (PSI)
-
What are the Ancillary Indexes and Subtests, and what are they used for?
- Quantitative Reasoning Index
- Auditory Working Memory Index
- Nonverbal Index
- Cognitive Proficiency Index
- General Ability Index
- They allow the clinician to explore specific cognitive hypotheses related to children’s WISC-V scores
-
what are the Complementary Index Scales used for?
They are designed to provide examiners with more detailed information relevant to psychoeducational evaluations of children referred for specific learning disorders
-
Other Important IQ Tests:
Stanford-Binet Intelligence Scale
One of the oldest and most widely used
The reliability estimates, using a measure of internal consistency for the FSIQ is .98
-
Other Important IQ Tests:
Kaufman Instruments
designed to assess children 3-18, with the intention of assessing children fairly who are from diverse backgrounds, minimizing ethnic differences in performance
-
Other Important IQ Tests:
Language-Free and Culture-Free IQ Tests
- Raven’s Standard Progressive Matrices
- Peabody Picture Vocabulary Test-IV
- The Test of Nonverbal Intelligence 4
-
what are the uses of
Group Intelligence Tests
- Given in conjunction with Group achievement tests
- Initial screening tools for children needing further testing (LD, DD)
- Evaluate an entire school
-
What are the limitations of group intelligence tests?
- Cannot observe behaviors that reflect the level of motivation
- Requires more reading-problematic for individuals with limited reading skills.
- Not sensitive to individual’s culture, background and language proficiencies
- Not as sophisticated and detailed as individually administered tests
-
Is Intelligence Stable ?
- Infants and preschool children have the least stable IQ scores
- IQ is fairly steady throughout adulthood with slight decline after age 65
-
What do IQ test scores Predict?
Academic performance r=.5
-
Is Intelligence Hereditary?
- Very controversial area of study
- Hereditability Index for IQ = .5
-
What Environmental Factors Influence Intelligence?
- Cultural environments
- Schooling and the amount of schooling
- Familial environments (parents interest in achievement; severely neglectful or abusive )
- Exposure to toxins (lead; prenatal exposure to large amounts of alcohol in the womb)
-
Are there group differences in intelligence?
- Gender differences-no general intellectual differences, but men tend to score better in visual-spatial ability and women better on verbal tasks
- Ethnic differences-African Americans, Hispanics, and Native Americans tend to score lower on IQ tests than European and Asian Americans
-
what are the three
Types of Achievement Test
- Survey Achievement Batteries
- Individual & Diagnostic Achievement Tests
- Criterion-referenced and minimum-level skills assessment
-
what is
the DESCRIPTION OF THE WIDE RANGE ACHIEVEMENT TEST 4
- norm-referenced test that measures the basic academic skills of word reading, sentence comprehension, spelling, and math computation.
- standardized on national sample of over 3,000, age from 5 to 94 years.
- normative sample stratified controlling for age, gender, ethnicity, geographic region, and parental/obtained education as an index of SES
- Alternate forms, designated the Blue Form and the Green Form, were developed and equated during standardization
-
What are the
WRAT 4 Subtests
- *Word Reading: measures letter and word decoding through letter identification and word recognition.
- *Sentence Comprehension: measures an individual's ability to gain meaning from words and to comprehend ideas and information contained in sentences through the use of a modified cloze technique. *Can be combined to form a Reading Composite Score
- Spelling: measures an individual's ability to encode sounds into written form through the use of a dictated spelling format containing both letters and words.
- Math Computation: measures an individual's ability to perform basic mathematics computations through counting, identifying numbers, solving simple oral problems, and calculating written mathematics problems
-
What are the Uses of the WRAT 4
- Collect initial data for psychological, educational, and vocational assessments;
- Reevaluate individuals diagnosed with learning and/or cognitive disorders;
- Contribute to research projects needing assessment of basic academic skills for pre-testing and post-testing purposes;
- Evaluate achievement-ability discrepancies to identify specific learning disabilities;
- Assess specific academic skills as part of a more comprehensive study of psychological and neuropsychological functioning;
- Determine a minimal level of proficiency needed to perform in certain educational and/or vocational settings; and
- Assess an individual's academic progress over time.
- Cannot be used alone for diagnostic purposes
-
WRAT Reliability and Validity
- Internal consistency reliability ranges from .94 to .98
- WRAT validity range between .42 and .92
-
Strengths-WRAT 4
- Ease of administration and scoring; takes very little time.
- Psychometrically sound
- Has excellent standardization
- Correlates well with other achievement and cognitive tests
- In clinical studies, separates people with learning or cognitive deficits from people without
-
Weaknesses WRAT 4
- Only screens for strengths and weaknesses
- Does not measure other important achievement abilities.
- In later adolescent and adult years, WRAT-4 does not adequately measure skills of readers that are above-average or advanced.
- Only a small number of appropriate items for younger children being tested.
