Wechsler Intelligence Scale for Children-Fourth Edition (WISC-IV)
Wechsler Intelligence Scale for Children-Fourth Edition (WISC-IV) is the Fourth edition of the Wechsler Intelligence Scale for Children (WISC; Wechsler, 1949). It is an individually administered clinical instrument for assessing the intellectual ability of children aged 6 years through 16 years, 11 months. The child's performance on these various measures is summarized in three composite scores, the Verbal, Performance and Full Scale IQs, which provide estimates of the individual's intellectual abilities according to each age group. The Full Scale IQs summaries the overall performance on the HK-WISC and provides a broad assessment of general intellectual ability. The Verbal IQ provides an indication of verbal comprehension, including the ability to use verbal skills in reasoning and solving problems, and the capacity to learn verbal materials. The Performance IQs reflects the efficiency and integration of the perceptual organization, including non-verbal reasoning skills, the ability to employ visual images in thinking, and the ability to proess visual material.
