本文发表在 rolia.net 枫下论坛David Wechsler is best known for developing several widely-used intelligence tests, including the Wechsler Intelligence Scale for Children (Wechsler, 1949) and the Wechsler Adult Intelligence Scale (Wechsler, 1955).
Updated versions of these tests remain popular in the 21st century (WISC-IV®, 2003; WAIS-III®, 1997) and new tests founded on Wechsler’s work continue to be developed by other researchers (e.g. Wechsler & Naglieri, 2006).
Wechsler is also notable for his use of the deviation quotient (DQ), a technical innovation that replaced the use of mental ages in computing IQ scores. This greatly improved the utility of normative comparisons when intelligence tests are used with adult examinees (Edwards, 1994).
The Wechsler Intelligence Scale for Children—Fourth Edition® (WISC-IV®) was published in 2003. It has been normed for use with children aged six through sixteen years and eleven months.
It yields a full-scale IQ score and four index scores:
(1) Verbal Comprehension (VCI, less formally refere to as the "Verbal IQ")
e.g. similarities, vocabulary and comprehension activities
(2) Perceptual Reasoning (PRI, less formally refere to as the "Nonverbal IQ")
e.g. matrix reasoning, block design and picture concepts
(3) Working Memory Index (WMI)
e.g. letter-number sequencing and digit-span
(4) Processing Speed Index (PSI)
e.g. symbol search and coding.
Registered psychologist practice in Counselling, School Psychology can administer the test.
WISC-4 test is a great method to have a reliable intellectual profile of your child, and assists determining candiacy for a gifted program.
My son, 8 years old, achived following scores in WISC-4 Test:
(1) VCI: Range-> Very Superior; Percentile -> 99.9; Score -> 146
(2) PRI: Range-> Very Superior; Percentile -> 99; Score -> 136
(3) WMI: Range-> Upper end of average; Percentile -> 70 Score -> 108
(4) PSI: Range-> Superior; Percentile -> 94 Score -> 123
Full Scale IQ(FSIQ): 139
He is attending a private school, and now we know he is a gifted child.
His WMI score is relatively low, and the psycologist explains that the score shows that his best study style is to be instructed within a relatively smaller group.更多精彩文章及讨论,请光临枫下论坛 rolia.net
