An old issue in psychological assessment is to what extent power and speed each are measured by a given intelligence test. Starting from accuracy and response time data, an approach based on posterior time limits (cut-offs of recorded response time) leads to three kinds of recoded data: time data (whether or not the response precedes the cut-off),…

The Jastak System of obtaining scores on "personality" dimensions is currently widely promoted. It is shown to be totally spurious, based on hereditarian doctrines long in disrepute, and dangerous in use. The promotional techniques used are also described. (Author)

The use of psychological and educational tests in World War I led to their adoption in schools for testing intelligence and achievement in order to classify students academically according to a national norm. After World War II, rapid changes in occupational and social structure demanded the education and identification of students for employment.…

A survey of 97 school psychologists found that the majority felt they needed additional training in administering, scoring, and interpreting the fourth edition of the Stanford-Binet Intelligence Scale. Thirty-four percent were using the fourth edition. Rank ordering of instruments of choice was: Wechsler scales, Kaufman Scale, old Stanford-Binet,…

The clinical inference process in test interpretation is described so that people can more easily communicate about it, teach it, and learn it. Chapter 1 compares different levels (concrete, mechanical, and individualized) of interpretation of the same test. Chapter 2 offers examples of an often-neglected kind of data necessary for individualized…

The Stanford-Binet Intelligence Scale: Fourth Edition is a conceptually new version of this traditional intelligence scale. The new scale has a solid basis in theory, but there is little evidence that the Binet matches its intended theory. This study was designed to determine whether the Binet corresponds to the theory that guided its…

The development and standardization of the third edition of the Wechsler Intelligence Scale for Children-Revised (WISC-R) are described. The existence of documented historical trends was a significant factor in the project to revise the WISC-R, which is the most widely used intelligence battery in North America. Development of the third edition…

Three tables are provided to aid in the clinical interpretation of factor scores for the Wechsler Adult Intelligence Scale-Revised (WAIS-R; 1981). The factor structure of the WAIS-R has proven to be robust across samples, tests, time, statistical analyses, measurement scales, and distortions of the distribution. Information necessary to make…

Bad intelligence tests seem as inevitable as death and taxes. However, new theories of intelligence are resulting in some promising developments. Thirteen approaches to the measurement of intelligence are described, divided into the following categories: classical psychometric; developmental; culture-sensitive; cognitive; biological; and systems.…

As spinoffs of the current revolution in the cognitive and neurosciences, clinical neuropsychologists in the 21st century will be employing biological tests of intelligence and cognition which record individual differences in brain functions at the neuromolecular, neurophysiologic, and neurochemical levels. Assessment of patients will focus more…

Questionnaire results from l04 psychologists serving the blind and partially sighted indicated disagreement on the tests used and on the evaluation of these tests. Tests of all kinds from 45 publishers were rated, and appropriate ages and populations (blind, partially-sighted) were suggested. (CP)
